In the solar world, panel efficiency has traditionally been the factor most manufacturers strived to lead. However, a new battle emerged to develop the world’s most powerful solar panel, with many of the industry’s biggest players announcing larger format next-generation panels with power ratings well above 600W.
The race for the most powerful panel began in 2020 when Trina Solar revealed the first panel rated at 600W. Not long after, at the SNEC PV Power Expo in China, JinkoSolar unveiled a 610W version of the Tiger Pro panel. Around the same time, Trina Solar announced that a more powerful 660W panel was in development. Amazingly, close to 20 manufacturers at SNEC 2020 showcased panels rated over 600W, with the most powerful being the Jumbo 800W module from JA solar. However, this panel was enormous at 2.2m high and 1.75m wide and will most likely not become commercially available.
Despite the publicity around the many high-powered panels, many PV cell technologies enabling these higher power ratings are universal. Traditional commercial and residential panels have also increased in size and power, with 400W to 500W panels now standard. The considerable increase in power is primarily due to increases in efficiency thanks to many innovations, which we describe later in the article.
Designed for utility-scale systems
The main driver for developing larger, more powerful solar panels stems from the desire to decrease the cost of utility-scale solar farms and ultimately reduce electricity prices. Since larger panels require an equivalent amount of connections and labour compared to smaller panels, the installation cost per kW is reduced, resulting in lower overall cost and decreased LCOE. As explained below, the new high-powered panels are much larger than the ones used on residential rooftops. Those wishing to use ten 700W panels on their home rooftop to get an easy 7kW will be a little disappointed. At this stage, most high-powered panels will only be available for commercial and utility-scale systems, plus the extra-large size is not well suited and challenging to handle on most residential rooftops.
The solar industry has been slowly shifting towards larger, higher-wattage panels. The front runners in the race were traditionally Trina Solar, Jinko Solar, Canadian Solar, Risen Energy and JA Solar as these well-known companies were the first to launch ultra-power panels with ratings above 600W over the last two years. However, more recently, Jolywood, Huasun and the lesser-known company Akcome have moved forward with panels rated above 700W utilising more efficient N-type TOPCon or heterojunction (HJT) cell technology.
Interestingly, premium module manufacturers SunPower (now Maxeon) and REC are not racing to develop larger format high-power panels. Instead, they are focusing on supplying their traditional residential and commercial customer base with high-efficiency panels. That being said, Sunpower has revealed a larger 540W panel in the next-generation ‘Performance 5’ series.

Larger panel sizes
In the past, most increases in power came from efficiency gains due to advances in solar PV cell technology. While that is partly a driver behind the massive jump in panel wattage, the main factor is the new larger cell and panel sizes being developed together with a higher number of cells per panel. These new cell formats and configurations mean the panels have become physically larger in size. Generally, these large-format panels are best suited for utility-scale solar farms or large commercial installations.
Traditionally, solar panels were available in two main sizes. the standard format 60 cell panels (roughly 1.65m high x 1m wide) used for residential rooftops, and the larger format 72 cell commercial size panels (roughly 2m high x 1m wide). Then half-cut cell panels emerged in roughly the same size but with double the amount of half-size cells at 120 cells and 144 cells. Besides the standard sizes, a few premium manufacturers, such as SunPower and Panasonic, produce unique 96 and 104-cell panels.
The industry-standard panel size for much of the last decade was built around the 156mm x 156mm or 6-inch square cell format. However, the new panel sizes emerging are up to 2.4m long and 1.3m wide and built around the larger 180 and 210mm wafer cell sizes. This is a size increase of 20% to 30% compared to the traditional 2.0m x 1.0m 72-cell panels, which naturally corresponds to a considerable boost in power.
Larger cell sizes
To decrease manufacturing costs and gain efficiency, most manufacturers moved away from the standard 156mm (6”) square cell wafer size in 2020 in favour of larger wafer sizes. While there are a variety of cell sizes under development, a few sizes have emerged as the new industry standard; these include 166mm, 182mm and 210mm. Many of the leading manufacturers, including Jinko, Longi and Canadian, aligned with the 182mm format. Trina Solar is pushing the larger 210mm wafer size, while Longi, the world’s largest mono silicon wafer manufacturer, uses 166mm and 182mm sizes, depending on the application.
To remain competitive, many smaller volume manufacturers may need to align with one of the new wafer sizes to utilise common wafer and equipment suppliers. For a complete history and insight into wafer and PV cell sizing standards, this detailed article from PV Tech examines the various wafer and ingot sizes, technology changes, and manufacturing trends around current and future PV cells.
Along with the different cell sizes, there is a myriad of new panel configurations built around the many cell combinations. The three most popular which have emerged are 66-cell (half-cut 132), 78-cell (half-cut 156), and 84-cell (half-cut 168) panels. The extra-large 210mm cells are also well suited to unique cell dividing formats such as 1/3 cut cells; where the square wafer is divided into three segments rather than the common half-cut or half-size cell.
To achieve these impressive power ratings, panels and cells have not just increased in size, but cell efficiency has improved substantially using numerous new technologies (listed below) along with more advanced rear-side passivation techniques like TOPCon.
- MBB. Multi-busbars
- PERC/PERC. Passivated emitter rear cell
- Heterojunction (HJT)
- TOPCon. Tunnel-Oxide Passivating Contact
- N-type silicon cells
- High-density cells. Reducing inter-cell gaps
Manufacturers are exploring ways to increase power and cell efficiency by spending big on research and development. N-type silicon wafers are one of the best ways to boost efficiency but have traditionally been more costly. However, the price gap between P-type and N-type silicon is reducing as the economies of scale lower the cost of manufacturing the high-performance N-type silicon wafers used as the basis for more efficient HJT and TOPcon cells. In the future, Perovskite cell technology is expected to become stable and viable, allowing manufacturers to create next-generation tandem cells with power levels up to 800W.
Of the many cell improvements, the most common technology used to increase efficiency has been multi-busbars (MBB). Traditional ribbon busbars (5BB or 6BB) are being rapidly phased out in favour of nine or more thin wire busbars (9BB). Some manufacturers, such as REC have even moved to 16 micro-wire busbars in the new Alpha panel series. Wider cells also mean more busbars can fit across the cell surface with 10 or 12 busbars cells also becoming more common.
Bifacial panels featuring MBB are also growing in popularity due to the increased power output by utilising the rear side of the panel to achieve up to 20% or more power (roughly 80W extra). However, bifacial panels are generally only beneficial over light coloured surfaces such as light sandy or rocky ground used in large MW scale solar farms located in more arid areas.
To further boost panel efficiency and increase power, manufacturers such as Trina Solar have introduced techniques to eliminate the vertical inter-cell gap between cells. Removing the typical 2-3mm vertical gaps and squeezing the cells together results in more panel surface area being available to absorb sunlight and generate power. Manufacturers have developed a number of techniques to minimise or eliminate the gap with the most common being to simply reduce the cell spacing from around 2.0mm to 0.5mm. The reason for this gap was due to traditional larger ribbon busbars requiring 2.0mm to bend and interconnect the front and rear of each cell. However, the transition to using much smaller wire busbars enabled the gap to be reduced significantly.
LONGi Solar is another manufacturer that managed to reduce the inter-cell gap down to 0.6mm by using what the company describes as a “Smart soldering” method using integrated segmented ribbons. This new technology uses a unique triangular busbar design across the front surface of the cell, with a very thin flattened section that bends and runs behind the cell to form the interconnection.
TR. Tiling Ribbon technology
Jinko Solar, currently the world’s largest panel manufacturer, developed what the company refers to as Tiling Ribbon or TR cells. Tiling Ribbon cell technology is the elimination of the inter-cell gap by slightly overlapping the cells creating more cell surface area. This in turn boosts panel efficiency and power output. The tiling ribbon technology also dramatically reduces the amount of solder required through using inter-cell compression joining methods rather than soldering. Shingled cell panels, such as those used in the Sunpower Performance series, uses a similar technology where overlapping thin cell strips can be configured into larger format high-power panels.
Several other leading manufacturers such as Q Cells have taken a similar approach to boost efficiency by completely eliminating the inter-cell gap. However, most manufacturers have taken the more common approach and reduced the inter-cell clearance as much as possible leaving a very small 0.5mm gap; this effectively removes the gap without having to develop new cell interconnection techniques.
N-Type TOPCon silicon cells
Cells built on an N-type silicon substrate offer improved performance over the more common P-type silicon due to a greater tolerance to impurities which increases overall efficiency. In addition, N-type cells have a lower temperature coefficient compared to both mono and multi P-type cells. N-type cells also have a much lower rate of LID or light-induced degradation and do not generally suffer from LeTID (light and elevated temperature induced degradation) which is a common problem with P-type cells.
TOPCon or Tunnel Oxide Passivated Contact refers to a specialised rear side cell passivation technique that helps reduce the internal recombination losses in the cell and boosts cell efficiency. The process has been available for several years but is now becoming the new industry standard as manufacturers strive to increase efficiency and performance.
How and why to use solar panels to charge an electric car
There may not be a better pairing than home solar panels and electric cars. Both of these exciting technologies represent a major shift away from how things have been done for a long time. Together they are sparking a revolution in self-reliance while helping to lead to a better future for everyone.
Electric vehicles (EVs) are more efficient and less expensive than gas cars and aren’t susceptible to the huge fluctuations in gas seen in recent years. Our solar-powered EV report shows that electric cars become even cheaper when you fill the battery at home with rooftop solar panels. In addition, pairing an EV with solar panels massively reduces your carbon footprint.
Let’s dive into the numbers to show exactly how much better EVs are compared to gas cars, then explore how many solar panels you might need to offset the energy needs based on the EV in your driveway.
- Home solar is cheaper and cleaner than grid power over the long term in almost every place in the United States.
- Public EV charging is even more expensive than grid power and no less polluting, for the most part.
- A home needs between five and ten 400-watt solar panels to charge an EV for an average day of driving.
- The same panels that charge your first EV will last long enough to charge your second and third, up to 30 or 40 years.
Why you should charge your electric car with solar panels
The reasons to charge your EV with solar panels are simple: it’s the cheapest and cleanest way to fuel a motor vehicle.
According to the U.S. Department of Transportation, the average American drives about 13,500 miles per year or about 40 miles per day. Over the course of a year, the driver of a gas-powered Hyundai Kona will pay around 1,440 for the 420 gallons of gasoline they’d need to go that far (based on 32 mpg fuel economy). Gas fluctuate, and due to inflation and the war in Ukraine, they’re basically as high as they’ve ever been:
Gas have jumped around wildly in the past two years. Image source: AAA
If the driver chose a Kona EV instead, they’d need to buy 27 kWh of electricity for every 100 miles they drive, or 3,645 kWh per year. At the average electricity price of 0.2282/kWh in California, they’d pay just 830 for their annual driving, saving over 600 compared to gas. In a cheap electricity state like Florida, where electricity costs about 0.1190/kWh, that annual cost to charge an EV drops to about 435, saving the driver 1,000 in fuel costs in a year.
But charging that EV from solar is even better. Let us count the reasons:
- The levelized cost of solar energy is usually cheaper than grid power.
- The cost of grid power goes up over time, while solar panels keep producing electricity without additional cost.
- Solar panels are far less polluting than gasoline or electricity from the grid:
- 420 gallons of gas results in 8,135 lbs of CO2 emissions
- 3,645 kWh of California grid power results in 1,837 lbs of CO2 (0.5 lbs/kWh 35 lbs CO2 from EV lithium battery production)
- 3,645 kWh of home solar energy results in 321 lbs of CO2 (0.088 lbs/kWh 35 lbs CO2 from EV battery)
Switching to an EV already means you’re cutting emissions by eliminating the need for gasoline and oil, but electricity from the grid still comes mostly from natural gas and coal. Just a handful of solar panels on your roof is enough to provide energy to charge your first EV, and your second, your third, and so on.
Again, those panels will last at least 25 years. No wonder they call it renewable energy. Who knows—maybe they’ll even help power your first flying car?
Here’s an infographic that shows why EVs and solar panels are a perfect match:
How many solar panels do you need to charge your EV?
Cost to charge an electric car with solar and without
When you own an electric vehicle, every outlet is potentially a way to get a few more miles into your car’s batteries. Realistically, though, you’ll want to find a Level 2 EV charger for home use or the equivalent of a Tesla supercharger if you’re out on the road.
There are basically three ways to get the juice that’ll keep your car on the road: the grid, public charging stations, or your own solar panels.
Here’s how much each costs:
|Type of charging
|Grid power at home
|0.10 to 0.40 per kWh
|Varies based on location and time; cheapest at night; cost increases over time
|Public charging stations
|0.31 to 0.69 per kWh
|Varies based on location and charging station owner; additional idle fees; some require monthly subscription; cost increases over time
|Solar power at home
|Levelized over the solar panels’ lifetime; additional solar energy can be used to offset electricity bill
Charging from the grid at home
You can charge an EV at home without solar, but it’ll cost you. Image source: Electrek
The ongoing cost of fuel from the grid is whatever you currently pay for a kilowatt-hour (kWh). In the United States, that can be between 0.10 and 0.40 depending on where you live, but the average is about 0.15/kWh. For every kWh in your battery, you’ll get about 3 to 4 miles of range, so about 12 kWh will get you a 40-mile round trip every day, at an average cost of 1.80.
That’s how it looks now, but electricity rise like everything else, so next year, you might be paying 2 or 3% more for electricity, and over the lifetime of your car, could rise much higher. Over the next 25 years, your average cost for a kWh of grid power will be around 19 cents if electricity rise 2.8% per year and you live in a state where electricity is currently 0.15/kWh.
At historical rates of energy cost increase, Californians will start out paying 830 per year to charge an EV, and end up paying about 1,300 per year in 20 years when using grid power.
Complicating matters just a bit is the concept of Time-of-Use billing (TOU), which means that electricity costs different amounts at different times of day. As an EV owner, you likely have the option of choosing a TOU plan and charging your car exclusively at night, when electricity is cheapest. TOU billing rates vary widely between states, with some overnight off-peak rates as low as 0.07/kWh, while others such as SDGE in California bottom out at 0.31/kWh.
Public charging stations
You won’t need it often, but public EV charging stations are sometimes necessary. Image source: Electrive
When you’re out in the world and need to top up the “tank,” you’re going to be looking for a public charging station to do it. To a certain extent, this is unavoidable if you own an EV, but you will save a lot of money if you can limit how often you do it.
Of course, there are free EV charging stations located all around the country, but for the most part, you’ll probably be paying for the electricity you need, and paying a lot, at that.
for charging vary by location. For example, Tesla charging stations currently cost around 0.25/kWh for Tesla owners, with higher in California and other states with high electricity prices. Services like Electrify America and Blink are even more costly, with a minimum charge of 0.31/kWh, and a maximum of 69/kWh for fast charging, sometimes dependent on whether you pay a monthly membership fee first.
At 0.31/kWh with a 4 monthly membership fee, charging with Electrify America would cost the owner of our proverbial Hyundai Kona 1,134 for their 3,645 kWh of charging—more than twice the average cost of charging with grid power at home, but still cheaper than gas!
Charging with home solar
Realistically, you won’t have wind turbines in your backyard, but you can dream!
If you pay for a solar panel system at your home, you’ll have to either lay out some cash or take a solar loan and pay over time. That’s not a small expense, but you can compare it to the cost of paying for electricity for the next 25 years.
To do that, you calculate the Levelized Cost of Energy, or LCOE, which is just the total cost of installation spread over all the electricity your solar panels will generate in their lifetimes and adjusted for inflation.
The good news here is the LCOE of home solar in the U.S. is currently about 0.06/kWh for systems with a current average solar installation cost of 3.00 per watt (as of February 2023) before the federal solar tax credit. In states with lots of sun, like California, or states with additional incentives, like Massachusetts, solar LCOE is much lower.
Basically, by guaranteeing your fuel source (solar) for the next 25 years, you’ll save a bundle of money on EV charging.
Do you need home solar batteries to store energy for EV charging?
Many people worry that they’ll need a battery such as the Tesla Powerwall to store solar energy they will later use to charge their EV. We’re here to tell you that’s not necessary, and it may not even be very practical.
Take the Tesla Model 3: depending on which version you choose, it will have a battery of between 54 and 82 kWh. You would need between 4 and 6 Powerwalls in order to store enough energy to fill the car’s battery from stored solar energy. Those Powerwalls would cost you at least 30,000, in addition to the cost of solar panels and a car.
Luckily, dropping 30 racks on sleek home batteries is unnecessary. First, you won’t often need to charge the car’s full battery in one go. Second, you’ll likely get net metering benefits, meaning you earn credit for extra solar energy that you send to the grid during the day, which you draw from when charging your car at night. With net metering, the grid acts as your “battery.”
As an added bonus, net metering and TOU billing can combine to make solar car charging a heck of a good deal. When your solar panels make electricity during the day, you earn net metering credits at the higher daytime prices, and are then able to charge the car at the low overnight prices. It’s the best of both worlds!
When solar charging isn’t a good idea
The numbers we gave above are averages that show the general benefits of solar and EVs together. There will always be specific cases where charging an EV from solar isn’t the best choice.
Specifically, if your state doesn’t offer net metering, your utility has very low overnight energy on a TOU plan, or your roof isn’t right for solar because it’s too shaded, you might be better off charging your electric car from the grid.
What about cars with solar panels built in?
We wish we had better news for you here, but cars with solar cells built into their bodies are not the answer to all the world’s problems. On the sunniest days with the car parked in the perfect, shade-free spot for the whole day, the solar cells will make enough electricity to get the car an extra 10 to 20 miles of range.
How to charge an EV with solar
Now that you know why you should charge an electric car with solar panels, here’s a little more about how to do it, to make sure you add the right number of panels and get a good value for the long term.
Here are the steps to use solar panels to charge your electric car:
- Step 1: Determine how many kWh you need for your car for your driving habits
- Step 2: Figure out how many solar panels you need to make those kWh
- Step 3: Purchase solar equipment that can make that much electricity
- Step 4: Get a Level 2 car charger
- Step 5: Enjoy!
Determine how many kWh you need every day
The first step is to find out how many kWh are needed to drive your car. If you keep track of mileage over a year, this step can be pretty easy. If not, you can estimate using an average number of miles per day.
As we said above, the average American drives about 40 miles per day. Let’s use that as a baseline. Here are the most efficient electric cars for 2023, excluding plug-in hybrid cars:

|Ford F-150 Lightning 4WD
Sorted from most efficient to least; data from FuelEconomy.gov; where multiple trim levels exist, the most efficient was chosen to limit each car model to one entry.
How many solar panels you need to charge your electric car
Based on the table above, you’ll need between around 10 and 12 kWh of electricity per day to charge the most efficient electric cars, but even power-hungry premium EVs like the Ford F-150 Lightning need less than 20 kWh per day for 40 miles of range. Now it’s time to figure out how many solar panels you’ll need to make that much electricity.
The average modern solar panel can put out around 400 watts under full sun, and gets between 3 and 7 peak sun hours per day, depending on where you live. That means our solar panel makes between 1.2 to 3.0 kWh of electricity every day (400 x 3 at the low end or 400 x 7.5 at the high end).
Let’s say you get 2 kWh per day, per panel. You’d need just five panels to make enough energy to charge a Tesla Model 3 battery and get 40 miles of range. That’s not very many! Of course, the number of panels increases if you need more than a 40-mile range.
Using the same math, you can determine that every EV on our list above needs just 5 to 7 solar panels to charge it every day. On the high side, you’d need 10 panels to make enough energy to drive 40 miles in a Ford F-150 LIghtning. Clearly, that is a truck that doesn’t sip the sun juice.
How many solar panels do you need to charge your EV?
Buy the equipment needed to charge your electric car with solar
Of course you can’t just stick five solar panels on your roof and plug them into your car. You need a solar panel system and all the equipment that goes with it.
A typical solar EV charging setup would include the following:
- Solar panels on your roof, mounted on metal racks and attached to the roof deck
- Either a string inverter that combines the DC output of the solar panels to AC, or microinverters that convert each panel’s output to AC and send it to a combiner box that connects to your main AC panel
- A Level 2 EV charger (or, combine 2 into 1 with an EV-charging solar inverter like the SolarEdge SE7600H)
What to do if you already have solar. If you’re a current solar owner and you’re thinking about adding an EV, you can just get a Level 2 EV charger if you have room for a new 50-amp breaker in your main panel. If you want to expand your solar array to meet the needs of charging an EV, you can use the guide above to see how many panels you’ll need for your estimated usage. You can also use our free and easy-to-use solar panel calculator.
Congratulations! You now have a solar-powered electric car. To be fair, unless you’re charging during the day when the sun is up, the electrons stored in your car’s batteries won’t be the same ones knocked loose from the silicon in your panels.
Instead, you’ll be producing enough solar electricity to offset your car’s needs over the course of the year, reducing your carbon footprint, and saving money. all at the same time. And those same five panels can produce electricity for decades to come. 25 years of fuel all on a small section of your roof.
The bottom line:
Making the switch from fossil fuels to solar electricity is good for your book, and also a great way to shrink your carbon footprint. The higher initial cost of an electric car can be quickly offset by the fuel cost savings you’ll see, and many EVs still qualify for state and federal electric vehicle incentives to reduce the upfront cost by 7,500 or more.
The amount of energy you’ll need depends on your car’s battery capacity and your average miles driven per day, but no matter how much electricity you need, you’ll probably save a lot of money if you charge that car with home solar panels.

The Hyundai Solar Roof Initial Details
Using the Sun’s power to generate electricity for cars is not a new idea. Carmakers have toyed with the concept ever since the 1950s when a so-called Sunmobile was presented in Chicago. For various reasons, the technology never stuck, and solar powered cars are seen as eccentric builds of eccentric people.
But that may change, and it may happen as soon as next year.
Back at the beginning of November, South Korean auto group Hyundai-Kia announced plans to fit several of its models with solar panel roofs starting 2019. importantly, these roofs will be available not only for electric or hybrid cars but for internal combustion ones as well.
In ICE cars, the goal of the system is to support the fuel burning process, which in turn will lead to increased fuel efficiency. For electric and hybrid cars, this could mean more range.
WHAT IS THE Hyundai SOLAR ROOF
Hyundai says the system it is working on has only three components: the solar panels, a controller and the battery.
The solar panels are of course meant to capture the Sun’s energy. The controller is supposed to control voltage and current with the help of Maximum Power Point Tracking (MPPT), allowing for the maximization of the current produced by the solar panels.
This power is converted and then either stored in the battery of the system or used when the car needs more juice to decrease the load on the alternating current (AC) generator.
Hyundai says it will be developing three different types of solar panels, meant for each of the three major group of cars: internal combustion, hybrid and electric.
For instance, the carmaker says that when using a 100W solar panel on a car, some 100 Wh of electricity can be produced. This, of course, can only be done in ideal conditions, meaning summer noon and 1,000 W/m2 intensity of radiation.
By all accounts, that amount of electricity might not seem as much, but given the fact that a car could spend possibly even five hours under the clear bright sky, as it waits for its owner to come back from the office, that could amount to 0.5 kWh.
At this stage of EV development, 0.5 kWh of power is the equivalent of a little under half of the battery capacity of the Ioniq hybrid.
SOLAR ROOF FOR HYBRID CARS
Hyundai will be fitting the first generation of its new technology on the hybrid cars of the group. In this case, the system is made of silicon solar panels integrated into a standard car roof.
As per the manufacturer, the system will be capable of charging 30 to 60 percent of the car’s battery over the course of a day, with the percentage depending heavily on weather conditions and other environmental factors.
SOLAR ROOF FOR ICE CARS
Using a solar roof to give power to an internal combustion car is a first in the industry, especially when considering the fact that Hyundai plans to do so on volume production models.
To be made semi-transparent, this second generation of the technology can also be integrated into a panoramic roof, making for both an aesthetic and useful application of the technology.
Hyundai says the solar roof on ICE cars will make them less pollutant as a result of the fact that they will not use as much fuel as before, helping them comply with stricter CO2 emissions rules.
SOLAR ROOF FOR ELECTRIC CARS
Electric cars, on the rise in terms of sales, are likely to produce a lot of strain on the electric infrastructure of many countries. Providing a car with the possibility of generating its own electricity, even for auxiliary systems, might take some of that strain away.
Hyundai says the solar roof for electric cars is currently in testing stages, but when deployed will probably help with both range and charging times.
