    LIVE POLL: Which Sunpower Maxeon solar panels are you considering?

    Intrigued by public opinion? It takes 1-second to anonymously discover the most popular Sunpower/ Maxeon solar panels like-minded people are researching globally with Solar Analytica Polls.

    Performance 3: 81/100

    Any great technology often accompanies an increased cost. The Performance 3 series is the slightly less efficient Sunpower/ Maxeon solar panel option where project budget restraints are a likely barrier. The engineers at Sunpower Maxeon seem to love solar module designs free from front surface busbar obstructions, and shingled-cell solar module designs are another innovative way to achieve this. Due to the absence of busbars and an almost gapless cell formation, the result is a strikingly seamless visual appearance compared to traditional cell formations. Compromising slightly on efficiency, the Performance 3 Series offers Sunpower/ Maxeon industry-leading quality more accessible than ever for the most diverse project types.

    Maxeon 3: 92/100

    Creating something marvellously efficient takes an impressive level of ingenuity. The Maxeon 3 is so remarkable in 2021/22 that even newer module types fail to exceed the 22.6% STC max module efficiency marker. A native Direct Current solar module, DC solar panels enjoy compatibility with most string and microinverter types, so you have the power to decide on how you will interact with your power supply. Three different Maxeon 3 variants exist within the range. Maxeon 3 (104-cell). ideal for most residential type installations. The Maxeon 3 (104-cell) BLK. an all-black module, is hard to ignore if aesthetic appeal and high performance are a requirement. While the Maxeon 3 (112-cell) is a mixed-use residential and industry option, supporting overall larger module dimensions to incorporate the additional cells. Expect the Sunpower Maxeon 3 to continue to dominate in 2022 through its outstanding energy density, where optimum space utilisation is critical.

    Model: Manufacturers model name. Output: Standard Test Conditions (STC) peak wattage range. Application: Manufacturers recommended application – Residential or Industry. Density: Maximum Power density per square meter at NOCT of the highest output module.

    Image; Sunpower Maxeon 5 follows a similar design to the Maxeon 3, yet uses a larger cell design for a slightly reduced efficiency.

    Maxeon 5: 92/100

    The beefed-up Maxeon 5 range is Sunpower/ Maxeon’s most durable solar module yet. A larger cell size than the Maxeon 3, efficiency is a minuscule 0.1% from being on parr. One particular limitation within the Maxeon 5 AC (60-cell) module will either make or break this module selection for most. This is an AC (Alternating Current) module with Enphase micro-inverters embedded on the module’s rear. A potential drawback that limits compatibility to the Enphase ecosystem only. That aside, it’s a pretty darn good ecosystem to be a part of as far as software and technology are concerned. The Maxeon 5 COM (72-cell) remains a DC (Direct Current) type solar module for commercial and industrial projects with varied inverter compatibilities. Expect the Sunpower Maxeon 5 to dominate as a combination of ultra-efficiency and as a complete all-in-one residential solution where extreme environments are present.

    Maxeon 6: 92/100

    The latest generation of mainstream Sunpower Maxeon solar panels, the Maxeon 6, tones down the durability criteria of its predecessor ( Maxeon 5 ) yet improves on the aspect the Sunpower/ Maxeon brand is renowned for, industry-leading efficiency. As the world demands higher power output modules, gone are the days of 60-cell module designs with installers and designers now accustomed to larger format 66-cell panels. Therefore, the Sunpower Maxeon 6 presents in 2 distinct variants; a residential 66-cell module in an AC only format and a conventional 72-cell DC commercial module.

    Model: Manufacturers model name. Output: Standard Test Conditions (STC) peak wattage range. Application: Manufacturers recommended application – Residential or Industry. Density: Maximum Power density per square meter at NOCT of the highest output module.

    Maxeon Air:

    An exciting release by Sunpower/ Maxeon set to be introduced in 2022, the Maxeon Air encompasses a new generation of flexible module designs free from glass and aluminium. Less energy dense than the Maxeon 3 and Maxeon 5, the Maxeon Air will improve rooftop design drawbacks from mounting hardware, in turn improving the power density of the system as a whole. Watch this space! Subscribe now to be the first to know how the Sunpower Maxeon Air ranks in the Solar Analytica assessment Criteria (solar modules).

    OVERALL: 89/100

    With decades of admires in a similar Apple cult following manner, there’s no denying that people love the appeal of the Sunpower/ Maxeon module range. Boasting an elite spectra of solar module offerings, you’re going to have to be prepared to pay a little more than most. The astute shopper, you calculate the upside beyond hypothetical/ basic ROI (Return on Investment). likely (than other brands) to improve the value of your property, you’re investing in reliable energy production beyond the next 25-years. Which, we’re sure, makes that little extra at the point of sale a lot less when you’re energy supply operates seamlessly and is characteristically more sophisticated than your neighbour’s cheapy. If that’s not enough to get you all Sunpowered-up, don’t forget Sir David Attenborough’s stark message in 2021’s Breaking Boundaries – The Science of our Planet Film (recommended viewing!). The planet as we know it is at a tipping point. Abandoning a throwaway society is one step to ensure humanity continues (i.e., you and your children have a non-toxic planetary place to call home). If reliable, clean energy with less waste is the path forward, Sunpower Maxeon solar panels are an intelligent investment towards one of the most technologically advanced module offerings, no matter your preference.

    How much do solar panels cost?

    Solar panels generate “free” electricity, but there are still costs associated with installing them. On average, solar panels cost 17,430 to 23,870 after federal tax credits.

    Supply chain constraints led to solar photovoltaics (PV) price increases in 2021, but we saw costs go back down in 2022.

    Key insights

    • In 2023, the average cost for a residential system is currently 3 to 5 per watt.
    • It typically takes five to 15 years to break even on installation costs.
    • Solar leases and PPAs can reduce the cost but aren’t eligible for the federal tax credit.

    Average solar panel cost by state

    You can get a better sense of how much you can expect to pay for a solar installation in your area with a state-by-state comparison. The data in this table is based on average installation costs for a 6-kW solar panel system, a common size for a residential installation.

    State Cost for 6-kW system (before tax credit) Cost per watt (before tax credit) 2022-2032 federal tax credit value (30%) Cost for 6-kW system (after tax credit)

    How much does it cost to install solar panels?

    The average cost to install solar panels in the U.S. is 20,650 after federal tax incentives, according to EnergySage. Depending on the size of your home and your energy needs, however, your costs could range from 10,000 to 30,000 or more.

    Most installers set the price according to the system’s wattage, with the average around 3 to 5 per watt. The cost per watt is the price you pay for each “unit” of energy the solar panel system can produce.

    For example, if a solar panel system has a cost of 3 per watt, it costs 3 for every watt of energy it can produce. If the solar panel system can produce 5,000 watts of power, then the system’s total cost would be 15,000 (5,000 watts x 3 per watt).

    If you just need a few panels for a small do-it-yourself project, start at around 200 to 350 per panel (between 80 cents to 1.40 per watt).

    Regardless of the size of your system, it’s worth it to get a few quotes — even the difference between 3 and 4 per watt can add up to thousands of dollars.

    For example, a ConsumerAffairs reviewer in California was quoted almost 26,000 for a 5-kW system (14 355-watt panels and an inverter), which works out to 5.20 per watt.

    “For a 4.97-kW system … it should be priced between 13,071 and 17,047. I personally would have expected a price of 13,668 for a 4.97-kW system (2.75 per watt),” the reviewer told us.

    Solar panel installation cost breakdown

    Local climate and the availability of sunlight in your area all play a role in how much you end up paying.

    Your energy needs Your energy needs determine how many panels you need, which affects the overall price of your solar system installation.

    To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most American homes end up needing 15 to 30 panels to meet their electrical demands. The standard size for solar panels is about 5½ feet long by 3 feet wide, so consider the size of your roof.

    Larger systems require more materials and labor to install, so they generally cost more than smaller systems. If you have limited roof space, you might need to get more efficient (and more expensive) panels.

    • Durability: Solar panels are designed to last decades, so they should withstand harsh weather conditions and extreme temperatures. Look for panels with a strong frame and tempered glass.
    • Efficiency: Higher-efficiency panels convert more sunlight into electricity, meaning you can generate more power with fewer panels. Look for panels with a high efficiency rating — typically above 18%.
    • Warranty: Panels typically come with a warranty ranging from 10 to 25 years. A longer warranty indicates that the panel manufacturer is confident in the quality of its product.

    Of the three types of panels available, monocrystalline and polycrystalline are most commonly used to power homes. In general, monocrystalline panels are more efficient, but they’re also more expensive compared with polycrystalline panels.

    Hard and soft costs Installing a solar panel system has two main expenses: hard and soft costs. Hard costs are the materials needed for the design, such as the panels, wiring and inverter. Soft costs are associated with labor, permits, deposits and administrative expenses.

    Solar panels — the main component of a system — usually make up the largest portion of the cost, but other hardware (for example, you might also want to buy a solar battery for energy storage), plus labor and permits, factor into the overall price.

    • Inverter: This device converts the generated DC electricity into AC electricity that can be used to power your home. The cost of an inverter depends on its size and efficiency, but on average, it can cost between 1,000 and 3,000.
    • Mounting system: This is what holds the panels in place on your roof. Costs vary depending on the type of installation, but it generally costs between 7 cents and 20 cents per watt.
    • Electrical wiring and hardware: This includes the wiring, switches and circuit breakers required to connect the solar panel system to your home’s electrical system. Electrical wiring and hardware costs typically range from 10 cents to 20 cents per watt.
    • Labor: The cost to install also includes an electrician, who handles wiring, hooking it up to your house and setting up various electronics to convert the power from the panels to the same AC voltage as you have in your home. Labor costs usually range from 50 cents to 1 per watt but can vary greatly depending on where you live and the complexity of the installation.
    • Permits: Permits ensure the solar panel installation is safe, follows regulations and can qualify for incentives and rebates. Fees vary based on location, but residential solar permits typically cost a few hundred dollars. Some state regulations cap permitting fees (Colorado caps them at 500 for residential projects and 1,000 for commercial projects; California caps residential fees at 450).

    The condition of your roof Get a thorough inspection of your roof now, and make sure you get pictures. If your roof needs repairs, it’s better to take care of that before installing solar panels — it’s more cost-effective than removing the panels and reinstalling them later.

    A reviewer in California told us they discovered leaks in their roof a year after installing panels. They said the solar company charged 5,000 “to take the panels down and reinstall them after the roof was replaced” and said “if I had known the roof was in such bad shape, I would’ve replaced the roof before installing the panels.”

    Federal and state incentives The federal solar tax credit, also known as the Investment Tax Credit (ITC), is a tax credit for 30% of the total cost of a new solar PV system. Homeowners, businesses and nonprofits can qualify, but there are some limitations. For example, you must own the panels — solar leases and PPAs do not qualify for the tax credit.

    State incentives also help reduce the initial cost, but not everyone can take full advantage of them. Look for policies and incentives by state through the Database of State Incentives for Renewables Efficiency (DSIRE). Some states, like Massachusetts, offer additional discounts or even free systems for low- and moderate-income households.

    It’s usually in your best interest to take advantage of state clean energy programs when you can — it lowers your upfront costs and shortens your payback period.

    How much do solar panels save?

    Switching to a solar energy system could cut your energy bill by 75% or more. The savings you see will depend on where you live, what the climate is like and your particular energy needs.

    Like a lot of solar energy customers we talk to, a reviewer in Pennsylvania said they went solar to “help [the] environment while saving money. During the summer when the central air is going full blast, my electric bills are either 0 or less than 10.”

    The average U.S. electric bill is 80 to 178 per month, according to the U.S. Energy Information Administration.

    The average American electric bill is currently between 80 and 178 per month, totaling around 1,500 each year, according to the U.S. Energy Information Administration. Depending on how much you pay out of for a solar energy system, it could take seven years or longer to break even, according to Wayne Turett, the founder of The Turett Collaborative, an architectural firm that specializes in sustainable designs.

    Another reviewer in Texas was able to take their “electricity bill down significantly, so even with the price we’re paying for the solar panels and the amount of electricity we’re using … it’s still much cheaper than what we were paying before we had them.”

    But some people see their electricity bills go back up if they run into a problem with their system — a reviewer in Nevada didn’t realize their inverter needed to be replaced, leading to an unexpected increase in their utility costs.

    “Everything had been going well and my energy bill had averaged 13 to 15 a month,” said one reviewer in Nevada. “Until I received a bill at the end of September 2022 in the amount of 429 from NV Energy.”

    So, keep in mind there’s some maintenance after installation, like panel cleaning and occasional repairs, which adds to the overall cost. Most solar energy companies offer monitoring apps that help you see how much energy your system is producing and when maintenance may be required.

    How can I pay for solar panels?

    Like buying a new car, you can pay for solar panels outright — but most people don’t.

    Homeowners and business owners often use loans, solar leases or power purchase agreements (PPAs) to pay for the upfront costs. You might also consider a cash-out refinance or HELOC.


    If you can pay cash, it’s usually cheaper in the long run. For example, consider this review from a customer in California:

    “Financing it was 18,000. But if I paid cash, it was 15,000 and they gave me a 1,000 debit card. It only cost me 14,000. I’m totally satisfied. I haven’t paid any electric bills in six months now. I’d recommend it to anybody.”

    Solar loan

    In general, solar loans work a lot like any other kind of loan: There’s an application and approval process, and you repay the loan amount in installments over time. Whether or not it makes sense for you comes down to your terms and break-even point.

    A solar customer in California “did the math,” and everything worked out:

    “Instead of paying 100 or 200 for the electric bill, if I use the same amount of energy or less, I will end up paying just the financing, which is 150,” they said. “But only for six years, and then after that, the panels will be mine and I don’t have to pay anymore.”

    Just remember to pay attention to the interest rate. Another reviewer in California said they’re “paying more for the loan payment than I save from the utility. Interest payments alone are over 1,000 per year and this will continue for a long, long time.”


    With a solar lease, you don’t own the equipment; instead, you make monthly payments to use them for the duration of the lease term. Your leasing company is responsible for maintaining and repairing the solar panel system during this time.

    Another customer in California said they “opted for the lease approach instead of a purchase. So, we did not have to put any money upfront at all. Zero. I work in finance/accounting and generally feel that if it sounds too good to be true, it usually is. But in this case, it truly has turned out even better than we could have hoped for.”

    At the end of the term, you typically have the option to renew the lease, purchase the system at “fair market value” or have the leasing company remove the system from your property.

    Power purchase agreement

    A power purchase agreement (PPA) is another way to get solar panels installed on your property without paying for them upfront.

    An energy service company (ESCO) installs the panels for you but owns and maintains them. You then purchase the electricity generated by the solar panels from the ESCO at a fixed price.

    You can still save money on your electricity bills with a PPA, but some reviewers describe feeling “stuck” with a company.

    » WHAT’S THE DIFFERENCE? Solar lease vs. solar PPA


    In general, installing solar panels is a good investment. Studies show that homes with solar panels sell for more than homes without them, and that increase in value can be significant.

    • A study by the Department of Energy’s Lawrence Berkeley Laboratory found homes with solar panels sold for about 15,000 more, on average, than comparable homes without solar panels.
    • A National Bureau of Economic Research study found that solar panels added an average of 20,194 to the sale price of homes in the San Diego and Sacramento areas.
    • Zillow found that, on average, homes with solar panels sold for 4.1% more than comparable homes without solar panels.

    How much value the solar panels add depends on your system’s quality, location and other factors.

    The number of solar panels you need varies based on your energy usage, the efficiency of the panels and other factors.

    The average household uses 886 kWh per month in electrical power, according to the Energy Information Administration.

    A solar panel typically produces about 1.5 kilowatt-hours (kWh) per day, so if your daily kWh usage is 30, you would need 20 solar panels to generate all of your energy needs.

    • Energy usage: To estimate the amount of energy you’ll need, you need to know your average kilowatt-hours (kWh). This number should be on your utility bill as “kWh used.” To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.
    • Panel efficiency: Next, you need to find the solar panel efficiency, which is the amount of energy the panel can produce per hour of sunlight it receives.

    Sometimes, you might make more electricity than you need, especially on sunny or windy days.

    Net metering is a system that lets you send any extra power your panels produce back into the power grid (the big network of wires that carries electricity to everyone’s houses). In exchange, you get a credit on your electricity bill.

    This means that when your solar panels aren’t generating enough electricity, such as at night or on cloudy days, you can still use electricity from the grid without paying for it because you’ve already earned credits through net metering.

    A reviewer in Texas explains how it worked for them: “When I first signed up, my contract was a net metering, so I paid a certain cost of kilowatt-hours used, and the utility company purchased back from me at that same price. If I generated 200 and consumed 200, my net usage was zero, and my bill was essentially zero. My contract ended and I had to renew it.

    They continued: “Now, I’m paying 21 cents a kilowatt-hour for usage, and I’m only getting back 10 cents a kilowatt-hour for anything I push back to the grid. There’s another 40 a month service fee from the utility company as well. So the incentive isn’t quite what it was a year ago. Still, it’s a good value.”

    It’s a win-win situation: You save money on your bill, and the power grid gets more electricity to distribute to people who need it.

    Actually installing solar panels takes only a few days at most. Wiring is installed to connect the panels to an inverter, which converts the DC power generated by the panels into AC power for use in your home.

    “One of the most common misconceptions is that going solar is a complicated process that involves a lot of work and expensive equipment,” said Alan Duncan, founder of Solar Panels Network USA. “In reality, the process of buying and installing solar panels is relatively straightforward, and many companies offer turnkey solutions that take care of everything from the design to the installation of the system.”

    Once the installation is complete, an inspector checks the system to ensure it meets local safety and building codes. The system is then connected to your utility’s power grid.

    Once that’s done, your solar panel system is activated and ready to generate electricity. You can monitor the system’s performance and energy production using a monitoring system provided by the installer.

    Bottom line

    Buying solar panels can get expensive. vary based on efficiency, capacity and location, but a residential solar panel system generally costs anywhere from 10,000 to 30,000. This includes the cost of the panels themselves, installation and any additional equipment needed.

    The good news is we expect to see solar hardware continue to get cheaper, thanks to advancements in technology and increased competition in the market.

    If you aren’t financially ready to install solar panels yet, you still have options to incorporate solar technology into your life with solar phone chargers, solar panel cars and passive solar home design.
