    Frequently Asked Questions

    A: It is a complete turn-key solar energy system that contains a solar panel design that fits your roof, full installation of solar panels, microinverters, and mounting system, complete with a monitoring app for your phone. There are different price points to fit the budgets of the many people. IKEA, together with SunPower, intends to make clean energy affordable, accessible and easy to understand.

    A: In order to provide to our customers with great technical expertise, IKEA is partnering with SunPower. SunPower has been in business for more than 37 years and globally has more than 13.2 GW of installed solar capacity to date. That’s the equivalent of powering over 7.5 million homes each year. SunPower’s solar panels among the most efficient and durable technologies on the market. The Home Solar offer combines the IKEA knowledge of life at home with SunPower’s technical expertise in solar energy to secure a great customer offer and experience. You will be redirected to the SunPower website after signing into your IKEA Family account for more information.

    A: First, sunlight hits a solar panel on the roof. The panels generate direct current (DC), energy which flows to an inverter. The inverter converts the electricity from DC to alternating current (AC), which you can then use to power your home. It’s beautifully simple and clean, and it’s getting more efficient and affordable all the time. The solar system generates electricity during the day to power your home. If you have a solar storage system, any excess solar energy generated can be stored in your home solar storage battery. In the evening, the energy stored in the solar storage system can be used to help decrease the amount of electricity drawn from the grid. The solar plus storage system enables you to generate your own electricity and then use it when it best suits your needs.

    A: When you install solar panels you will save by reducing your electricity consumption from the grid and thus, you’ll see a reduction in your electricity bill. If you choose to install a battery, your savings will likely be even higher as you can consume the excess electricity you produced and stored during sunny hours in the evening or when the sun is not shining.

    A: One of the advantages of solar energy is that the addition of PV panels can increase home values. In 2019, an online real estate marketplace found that U.S. homes with solar panels typically sell for 4.1% more than comparable homes.

    Home Solar offer

    A: IKEA is launching the partnership with SunPower in the state of California in September 2022. California is an excellent place to start, as it leads the United States in residential solar installation. IKEA Home Solar is already present in Australia, and 10 markets in Europe, so we are just getting started, with desire to expand soon.

    A: No, the offer is currently for a complete solar system, including a battery if desired. We would suggest you reach out to the company that originally installed your panels to see if they can assist to install more panels or a battery.

    A: You would need to own the home where you want the solar system to be installed. In case you live in a rented home the purchase of the solar system must be done by your landlord.

    Solar energy

    A: Solar energy is the most abundant source of energy on Earth. About 173,000 terawatts of solar energy strike the Earth at any given time. more than 10,000 times the world’s total energy needs. Going solar is for everyone, and there are 47.1 gigawatts of total solar capacity already installed in the US nationwide. The history of photovoltaic (PV) solar power began with scientific experimentation during the late 1800s. The environmental benefits of solar power are undeniable, and it’s being embraced widely because it can save homeowners money on electricity.

    A: Most of the electricity we use at home comes from fossil fuels and effects our planet and health. One of the easiest and most impactful things you can do to is to switch to clean electricity at home. Also, it helps reducing your electric bill as you can generate about 30%-100% of the energy that you consume. On top of that, by adding storage to a solar system, you can store your own energy on-site, further reducing your reliance on grid electricity and preserving the ability to power your home in the event of a power outage or use it during peak times when electricity rates are the highest. Software monitoring examines solar production, home energy use and utility rates to determine which power source to use throughout the day. maximizing the use of solar, providing you the ability to reduce peak-time charges, and the ability to store power for later use during an outage.

    • Solar (PV) panels
    • Inverter/microinverter
    • Mounting system
    • Cables Energy monitoring system
    • Battery (optional)
    • EV charger (optional)

    A: The installation of a solar system includes the mySunPower Monitoring app provided by SunPower where you can visualize and monitor your consumption and production. In case you install a battery or electric vehicle charger you’ll also be able to monitor the charging status of these devices. On top of that, the app can recommend you some consumption habits so you can save even more with your solar system.

    A: At this time, our FOCUS is on residential solar systems. Check back with us to see if the offer is updated in the future.

    A: How much electricity you get depends on several factors, as the weather and the quality and efficiency of your solar panels. In general around 17-20% of the incoming solar energy is transformed into electricity. Normally it indicates how much electricity (kWh) is being produced per installed kWp. These numbers are usually around 800-1100 kWh/installed kWp, depending on the yearly insolation and tilting of the panels. Other factors that affect the production are shadowing, temperature, snow/dust coverage, contamination etc. Depending on the size of the solar system and your consumption habits, the electricity generated could cover about 30%-100% of the energy that you consume.

    Q: How does weather affect solar energy? Do solar systems produce the same amount of energy all year round?

    A: Weather conditions can impact the amount of electricity a solar system produces. While more hours of direct sun exposure will indeed help a solar system generate more electricity, modern panels are quite efficient and can still generate energy in low light situations. No matter where you live, solar energy can be an excellent investment and a way to help combat climate change. Whether you’ll save money depends on many factors, like the cost of electricity, solar incentives available, net metering, the quality of your solar panels, shading, weather, among other factors. SunPower panels are leading in third-party durability testing, which means they can withstand some of the harshest weather conditions, including hail up to 1 inch in diameter. The installation is informed by local wind patterns and is comprised of components that have also been tested against extreme wind gusts. Underwriter’s Laboratories (UL) certification, ensures that every solar panel manufactured is required to undergo testing for extreme weather conditions. The UL certification proves that a solar panel has satisfied a number of safety, durability and quality assessments. However, it should be noted that this certification only ensures a minimum amount of testing. SunPower can provide more information on specifics of the solar panel for the system you choose.

    A: When you install solar panels you can save by reducing your electricity consumption from the grid and thus, see a reduction in your electricity bill after installation and activation. If you choose to install a battery, your savings can be even higher as you can consume the electricity you produced during sunny hours when the sun is not shining. Finally, the energy you produce but do not consume or store in a battery will go back to the grid and you can receive a credit from your utility. (see net metering)

    A: Net metering is a utility billing mechanism available in many locations that offers a credit to residential and business customers who are making excess electricity with their solar panel systems and sending it back to the grid. With net metering, the homeowner can receive a credit on their electricity bill for excess energy generated and sent back to the grid.

    Buying process, installation and warranties

    The design plan should also ensure compliance with local fire safety requirements. The installer will then submit these plans to your city/county permitting departments and to your utility company. The design and permitting phase typically takes approximately one to three months, depending on the jurisdiction. Your installer should keep you informed about the progress and let you know when it’s time to schedule the physical installation date.

    If there are no changes on the original proposal the contract is finalized. In case there are some amendments after the technical visit you would be requested to accept the amendment contract and in case you do so, the contract is finalized.

    When it is done, SunPower will install the solar system at your home. For more details regarding the installation please check “How is the installation conducted?” Once you’re connected to the grid you will start enjoying consuming your own produced electricity!

    SunPower will provide a limited warranty of the solar system, including a 25-year limited warranty for the panels, microinverters and racking, and 10-year limited warranty for the monitoring system and storage system.

    Q:Where are the solar panels produced, and how are the working conditions in the SunPower supply chain secured?

    A: IKEA has carefully chosen SunPower as a partner in the US. We put high demands on our suppliers to ensure that they comply with social and environmental responsibility. SunPower prohibits the practice of forced, bonded, indentured or child labor, or any exploitative labor practices throughout our workforce, and demand the same from their suppliers. SunPower Speaks Out: Forced Labor | SunPower SunPower panels sold in US are manufactured by Maxeon Solar Technologies in Mexico

    A: Solar is a form of renewable energy, which means it can’t run out. As long as there’s sunlight, there will be solar power. Solar energy generates 91 % less CO2 emissions than natural gas and 96 % less emissions than carbon. Solar cells are an important energy source fit for the future of the planet. A Connecticut study found that one home switching from fossil fuels to solar power had the same emissions impact as planting 150 trees every year. How does solar energy help the environment? | SunPower Solar panels are a manufactured product, and — as with any building processes — there is an environmental impact, from the chemicals used to make the panels to the transportation and beyond, but the impacts are far smaller than the impacts of burning oil, coal, and gas. However, Solar is one of the least-polluting forms of energy generation available and SunPower is committed to sustainability in every step of the process.

    SunPower Tesla Solar — Rooftop Solar Comparison

    As part of my family’s journey to learn more about residential renewable energy, I decided to look into solar panels for our house. We are in the middle of Texas, and who can forget power going out for one week across the entire state in February. We were fortunate, but many of our neighbors had to be without power for a week. The state has done minimal winter weatherization for the coming winter. I fear this winter will be bad, and if not this winter, an upcoming one in short order. Natural gas are spiking across the world. According to the Dallas Fed, natural gas and coal make up the majority of power production in Texas. The good news is that wind and solar have made great strides in Texas, but there is much more to go.

    A friend of mine mentioned that their average electric bill has increased to 170 a month this year from 140 a month last year. That’s a 20% increase. Retail consumers may have been isolated if they had a fixed rate plan during the freeze. Utilities had to keep buying at ridiculous wholesale prices. I’m sure they will lobby the government for rate increases to make up for all their losses. We can assume electricity will go up over the coming years. If the world continues warming, and summers get longer and hotter, that’s another reason our electric bills will go up.

    Tesla Solar

    Enter rooftop solar and batteries. The first step is having 12 months of electric bills handy. You want to calculate your total kilowatt-hours used in one year. That starts with finding your current electric rate. Ours is 10.9 cents per kWh. Our energy consumption was 14,400 kWh in a year. Our average electric bill was about 131 a month.

    Second step: contact many solar providers to get a quote. Tesla makes it easy on its website. Enter your address and Tesla will tell you how much solar and how many Powerwalls you need. Our address was not found, so Tesla asked us to enter some house information.

    Below is what Tesla recommends for a Solar Roof. Tesla is quoting 69,500 after the US federal tax credit, 100% estimated energy offset of our annual monthly bill, and 3 days of backup power using a Powerwall. Considering my roof was 35,000 to fix three years ago, and labor and construction costs have increased since then, this seems competitive.

    Below is Tesla’s quote for solar panels. This is a great price. Tesla would provide a 8.5 kW solar panel system along with 1 Powerwall battery. The cash price is 20,412 after the federal tax credit. The estimated energy offset is 73%, which means 73% of 140 would be offset. Be wary of solar companies providing you a 100% solar offset of your energy bill. Your roof’s potential has to take into account trees, roof shading, weather, pitch of your roof, and which direction the solar panels would be facing. The solar panel preference in the northern hemisphere is south facing or an azimuth of 180 degrees. Azimuth is the angle of your roof position from true north, with roofs facing true north having an azimuth of 0 degrees, and those facing south having 180 degrees. The opposite will be true for those in the southern hemisphere. A pitch of 30 degrees is ideal for solar production. Tesla offers financing of 10 years, with 10% down and 2.99% APR. For the below system, that comes to a price of 240 a month. Readers will note that is almost double our 140 a month in current electric costs.

    Savvy readers may ask, how long is the system guaranteed for? How much will it produce after 25 years? Tesla informs us on its Service and Warranty | Tesla Support page:

    Your solar panels are guaranteed by their manufacturer to at least 80% of nameplate power capacity for at least 25 years.

    Your entire Tesla solar system is covered by a 10-year comprehensive warranty.

    This includes the following aspects of your solar system. For details and exclusions, you can check your specific purchase agreement.

    I’m not thrilled the worst case capacity of the system might decrease by 20% over 25 years. That would leave us with a system size equivalent of 6.8 kW after 25 years. The average production size over 25 years is 7.65 kW (8.5 6.8, divided by 2). According to my utility, each 1 kW of system capacity facing south will generate 1,533 kWh per year. Taking the average system, we calculated that multiplying by 25 years and multiplying by 1,533 kWh gives us a total of 293,186 kWh produced. Our total cost is 240 12 months 10 years, for a total cost of 28,800. That’s a cost of 9.8 cents per kWh after the credit. This cost would be locked in for as long as we own the panels. As a reminder, that includes one Powerwall battery, which makes this a great deal, especially if the power is to go out. There is a new option that allows you to remove a Powerwall if you don’t want one.

    We recently mentioned SunPower’s move to help historically marginalized communities here. I’m supportive of the move. SunPower is listed on the Nasdaq as a public company. This week, the company decided to FOCUS purely on residential systems and sell off its commercial and industrial solar division. CNBC has more info.

    I contacted the company on its website and set up an appointment. I met with Salvador V. twice over the course of a week. Below is some key information from the proposal we reviewed.

    Above: A picture of our roof. We upsized our system by adding four more panels from the original proposal (dark orange).

    SunPower would install 22 panels, with a total solar system size of 7.194 kW. Lifetime production is estimated at 264,337 kWh. To repeat, we had calculated my monthly bill to be 131. Based on that, the system would offset 78% of my electricity consumption.

    The total out of cost was noted as 24,287 after the US federal tax credit. (Note: This does not include a Powerwall battery or any kind of energy storage battery.) The monthly cost of the system would be 109 a month over 25 years. That is how long SunPower will warranty the system, 25 years, which is phenomenal. Salvador noted a Powerwall from SunPower is an extra 16,000. Tesla Solar has a Powerwall listed for 10,500. The interest rate they offered me was 1.99%. Over 25 years, the total cost is 32,700 (109 12 25). If we divide that by a total production of 264,337, that gives us a total cost of 12.4 cents a kWh.

    SunPower’s warranty specifies the DC power will decline by no more than 2% a year for the first year, and the following years will not decline by more than 0.25% a year for the next 24 years. That means the system will be guaranteed to generate 92% of its capacity after 25 years. SunPower will repair, replace, or refund the original purchase price over 25 years for any valid claim. In their own words:

    “… will be at least 92% of the Minimum Peak Power rating (the “Guaranteed Peak Power” rating) and the AC power of the system will be at least 90% of the Peak System Power for the full 25-year warranty period.”

    That is an impressive warranty. When you install a solar system, the parts can be from different distributors and labor from another subcontractor. Who do you go to if you have a warranty claim? What happens if your part is no longer available? SunPower makes it easy. The company sells all of its equipment to one state distributor, and that distributor is captive to SunPower. In our case, Freedom Energy is SunPower’s captive distributor in Texas. If we had a warranty claim, I would contact my rep, Salvador. Freedom Energy would be responsible for the labor, fixing the system, and any parts needed under a claim. If needed, we can add a battery or more panels in the future. If you are in Texas and have interest in SunPower, you can contact my rep Salvador at Mention my name, Vijay Govindan, to him and you’ll save money on the system, I’ll make money, and we’ll being doing good together.


    After all was said and done, we went with SunPower for a few reasons. Reason 1: the lower monthly cost. Reason 2: no down payment. We can invest the down payment and 111 monthly savings compared to Tesla Solar in outside investments. Reason 3: the higher production capacity of the panels over 25 years. This advantage is offset by the larger Tesla Solar system size. Reason 4: time. SunPower estimates it can get the licensing, permitting, HOA approvals, and installation done within 2 months. I do not know how long it would take for Tesla Solar to do the same. I might not know until I finalize my order. Reason 5: the peace of mind of the long warranty period and ease of getting claims resolved. Reasons against the SunPower system are the expensive cost of the battery, higher system cost, smaller system size, and no battery being included in the proposal. If you can pay cash for your system, it’s a no-brainer — go with Tesla Solar and invest your savings. The SunPower app is not as good as Tesla’s, but with the changes at the top of the article, I am sure they will work to improve it soon.

    The bottom line is, whoever you go with — Tesla Solar, SunPower, someone else, or doing it yourself — it’s a good idea to explore renewable energy production for your home. Give it back to the governor, legislature, and utilities on escalating energy costs, brownouts, blackouts, and poor maintenance of the grid.

    I’ll leave you with the final slide in the SunPower proposal. Outside of the financial savings, the savings to the environment are significant. Below is the estimated impact form switching to the solar panels, every year. Stick it to the fossil fuel companies, their lobbyists, and favored donation recipients known as politicians. Take control of your energy production. At scale, this would dent natural gas and coal plants until they become unprofitable.

    Final note on net metering

    What happens in those months when we produce more than we consume, such as spring and fall? According to our utility, we would get no credit for those kWh, and they would go back to the grid for free. The utility will give us credit for what we produce at our retail rate, and charge us only for the net amount of electricity consumed. The catch is the full retail credit is only given if the solar panels did not produce more energy than our house consumed at the end of the billing cycle. That’s Texas for you.

    The ultimate goal for our family is creating apartment complexes that are sustainable, fashionable, and low cost. Solar and renewable energy will play a big role in bringing that vision to life. It’s one reason why we want to learn more about solar panels.

    Note: I own shares in Tesla, I own no shares in SunPower. You know by now this is not investment advice. Do your own diligence, read from a variety of sources on what you need to move to solar, and do what’s best for you.

    SunPower Solar Panels vs. LG Solar Panels

    If you are considering installing a solar system at your home or place of business, then you have many factors to consider. The paramount factor to many buyers is which solar panels (referred to as ‘modules’ in the industry) to choose. During your solar research, you will undoubtedly come across two solar module manufacturers: SunPower and LG. Both are widely recognized as high-end modules with SunPower leading the way. So which should you choose?


    SunPower is more expensive. Partnered with roughly 200 solar installation companies across the nation, sees SunPower pricing to be 0.57 per Watt higher than LG. This equates to a 3,420 on the total cost for an average sized residential solar system (6,000 Watts). This is a significant cost increase for most homeowners or business owners so it’s important to understand what differentiates the two brands and their products.

    Efficiency Nominal Power

    Solar module efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity. SunPower modules achieve a high of 22.2% with an average of 20.6%, while LG’s current products can achieve 19.5% with an average of 18.3% on the efficiency scale.

    Nominal power, rated in DC Watts, is an important characteristic of a solar module to consider. SunPower’s modules range from 327W – 360W, while LG’s residential modules ranges from 275W – 320W. LG does currently offer modules as high as 370W, but these are larger in size and are typically used for commercial solar projects. Nominal power is significant because if you are a homeowner who needs a 6,000 W system to offset your electricity consumption from the Utility, you would need 17 modules with SunPower or 19 modules with LG.

    Depending on how much available space you have on your roof, this may impact your decision. Also, if you plan to increase your energy consumption in the future (e.g. plan to have kids, want to get an Electric Vehicle, etc.) you may want to choose SunPower modules so you have enough space to install more modules in the future (if roof space is a constraint).


    Degradation is another characteristic of modules and it refers to their power decline over time. Most manufacturers guarantee their modules to degrade no more than 0.7% each year for 25 years. At 0.25%, SunPower’s X Series has the lowest degradation rates of any manufacturer. LG is better than average at 0.6%. After 25 years, a SunPower solar system is guaranteed to produce 92% of the electricity that it did at the time of installation while an LG solar system is guaranteed to produce 83.6%. The difference here may seem insignificant, but over the course of 25 years, this can add up.


    Homeowners and business owners who are concerned with aesthetics, often choose an “all black” module with a black frame and black back sheet. SunPower and LG both offer this style. However, SunPower’s all black module has a nominal power rating of 335 Watts, while LG ‘s is rated at 305 Watts. With a similar appearance, your decision to choose SunPower or LG should rely more on available roof space and the solar system size you need.

    Warranty and Bankability

    These two factors are closely related and should be discussed together. Warranties provide both security and peace of mind to consumers, but if the manufacturer goes belly up, their warranty is meaningless. SunPower leads the industry with their 25/25/25 warranty, covering performance, product defects, and labor. LG covers the performance for 25 years and any product defects and labor costs for 12 years. If you have a defective solar module after 18 years, SunPower will send someone out to replace the module at no cost to you, however, LG will not. That said, If you chose an installation company that has a 25-year bumper-to-bumper workmanship warranty, then this is a moot point.

    Now let’s take a look at the bankability of these two companies. Everyone has heard of LG. You may have a microwave, television, or refrigerator in your home that is made by LG Electronics. Unless you’ve looked into going solar, you likely have not heard of SunPower. Looking at the NASDAQ, SunPower’s stock price has steadily declined over the past year from 24 in March 2016 to roughly 8 today. LG stock have remained steady during that time period and have even risen slightly from 10 to 12. The solar industry is still relatively immature and changes in policy and advancements in technologies can have a direct impact on manufacturers. Soon after Congress extended the 30% federal investment tax credit for solar in December 2015, SunPower announced 1,200 layoffs and shares quickly dropped over 30% in trading. The diverse portfolio of LG protects itself from any changes specific to the solar industry, arguably, making them a more stable and bankable company.

    Coming Soon from LG

    LG has developed residential solar modules that seem to truly rival SunPower. The LG NeON® R modules appear to close the gap and even exceed many of the advantages that SunPower currently has over other products. If LG keeps the price point near the current modules they offer, homeowners and business owners may have a tough time justifying SunPower’s higher cost.

    Going solar can be a daunting task to many as there are many things to consider. The solar modules you choose are an important consideration, but many other factors deserve more attention.

    SunPower Vs. Tesla (Which brand should you choose?)

    The battle between solar tech giants such as SunPower vs. Tesla, more specifically Tesla Energy, will be more common in the future. Solar energy has come a long way since its humble beginnings in 1909. From feeble, costly solar water heating systems, solar technologies have provided notable breakthroughs toward decarbonizing grids and running space satellites. It’s unsurprising to see large organizations such as the U.N. and SEIA take giant strides towards net-zero carbon systems and sustainability, with solar at the dead center. With all countries setting ambitious climate change goals, we can expect many companies to jockey for the top spots and make the most out of this demand surge. This will culminate in close-knit competition in the solar energy market, which we’ll all benefit from.

    SunPower vs. Tesla: Tesla Overview

    While the Tesla name is synonymous with electric cars, the company has been part of the solar market for quite some time. Tesla Energy is a division of Tesla, Inc. that designs, manufactures, and sells energy storage systems and solar products.

    • Solar roofing: Tesla solar roof tiles/shingles
    • Solar panels: From third-party manufacturers
    • Energy storage: Tesla Powerwall

    Tesla Solar Roof

    During its launch, Tesla Energy marketed its solar roof tiles as an innovation over the typical rooftop.

    Based on our analysis, Tesla solar roofs are better than traditional rooftops since they allow you to earn your money back over time. And the best part? They don’t even look like solar panels (see figure below.)

    So, is a Tesla Solar Roof worth it? We believe opting for solar panels is still the quickest way to get your money back. Not to mention, Tesla is not ready to roll out solar roofs on a massive scale.

    Tesla Solar Panels

    Even though Tesla’s solar panels are slapped with the Elon Musk seal of approval, Tesla does not manufacture its solar panels.

    Panasonic was the initial supplier of Tesla’s solar cells before moving to other third-party manufacturers in the second quarter of 2021.

    The truth is, finding Tesla’s solar panel specifications is an arduous task compared to its PV peers. Check out their website and see for yourself. However, if you look hard enough, you’ll see that their main residential solar offerings post-Panasonic are as follows:

    Currently, SunPower’s primary offerings include:

    • Solar panels: SunPower Performance Maxeon panels.
    • Energy storage: SunPower SunVault Storage

    SunPower solar panels

    SunPower has two primary ranges of solar panels to choose from:

    Performance Panels

    SunPower’s Performance Panels make up the make cost-effective offerings from the company.

    These panels use a distinct shingled PERC-cell (based on P-type silicon) design made up of six strings of shingled cells in parallel. This makes the panels more resistant to micro-cracks — a common issue among convention square cell panels.

    The P-series is available in both DC and AC variants, and its residential panels range from 370 to 415 watts.

    Here’s a closer look at some of the P-Series panels:

    Ultimately, these design choices come together to form panels with extremely high levels of performance, efficiency, and very low degradation rates — approximately 0.2%/year compared to the average of 0.75%/year.

    For these reasons, SunPower and Maxeon back this range of solar panels with a whopping 88.25% retained capacity after a 40-year period

    Here’s a closer look at some of the P-Series panels:

    However, recently reported that Tesla has decided to become competitive in the pricing arena, stating that Tesla’s price reduction in its installation service will come from lowered installation costs and more powerful solar panel modules. This results in a 2.44 per watt cost before FTCs (Federal Tax Credits).

    In addition, Tesla has made the consultation / quoting process more seamless thanks to its convenient solar panel calculator.

    That said, SunPower is still holding its punches in this area. In their opinion, talking to a consultant is still the way to go to get a free evaluation.

    While SunPower is not wrong, the concept of empowering your potential clients does give Tesla the upper hand, at least initially. Not to mention this goes really well with their price-matching strategy.

    The Climatebiz Insight

    Looking at these figures, a 5kW solar panel system in the United States will cost you around:

    However, while the solar cell efficiency of SunPower helps reduce the cost of its entire system, Tesla still has a lower price for a 5kW residential system.

    Note to our readers: These systems will offset 78% of a home’s electricity consumption with a monthly bill of 130-150, depending on your state.

    Which company is right for you?

    Go with SunPower if you’re:

    • Detail-oriented and a fan of exhaustive approaches (leave no stone unturned!) like our lengthy deep dives on U.S. Solar Panel Installations.
    • A fan of a more tailor-fitted approach.
    • Value good warranty established reputations and love the 92% output guarantee after 25 years.


    SunPower is your best bet if you:

    • Value higher solar panel production capacity over 25 years (long-term savings).
    • Love a hands-on approach (which includes assistance in licensing, permitting, HOA approvals, and all that regulatory stuff).
    • Enjoy the peace of mind that comes with warranties from a company that has been in the game long enough.

    Don’t completely ignore solar roofs

    While we agree that the Tesla solar roof cost cannot compete with traditional solar panels, we don’t want to remove it from your options entirely.

    Tesla’s think tank definitely had a target market in mind when it created the Tesla Solar Roof concept. And given that it’s a relatively new and unique product, it’s crucial for you to learn everything you can about Tesla Solar Roofs before deciding if they’re right for you.

    Final thoughts

    We’re confident you can decide based on the information we provided you in this SunPower vs. Tesla discussion.

    Just remember; your solar system will be on your roofs for 25 years. Therefore, your chosen company will determine your renewable energy experience for decades.

    I am considering TESLA solar system and spoke to an engineer @ Tesla. According to him, Tesla now (Apr 2022) uses T400H TESLA panels manufactured at Buffalo factory. They no longer use Hanwha panels.

    You are correct Punit, we have already gotten feedback from Tesla. You can expect an updated article within the next week.

    Except that it’s been more than a month now and there hasn’t been any updates. So Tesla it is. Sunpower is 50% more expensive. Not worth it.

    Hi Oscar, please note we have now updated the article accordingly.

    I appreciate this comparison of solar panels as I’m researching options for our home and one of them is Tesla. However, I want to point out a misleading part of the article. You state that a SunPower solar panel will produce 8.25% more power than a Tesla solar panel because of the efficiency difference (22.3% vs. 20.6%) and use that conclusion to reduce the effective cost of a SunPower installation. That’s not accurate. A 400W solar panel produces the same amount of power (400W under ideal conditions) regardless of its efficiency. The more efficient panel does that using a smaller solar cell area. Indeed the SunPower 400W Maxeon 3 panel is 1.77 m^2 vs the Tesla T400H panel which is 1.98 m^2. So there’s indeed an advantage to higher efficiency panels, which is you can fit more production on a given roof size. But it does.not- mean the cost of a 5 kW SunPower installation should be reduced by 8.25% compared to a 5 kW Tesla installation. Both systems will produce the same amount of power so you should compare their non-adjusted prices.
