Choosing the best solar panel can feel overwhelming, but it''s easier than you might think. If you select a quality solar installer, in most cases they''ll install quality solar panels.
Many companies offer great solar panels. It''s your installer''s experience and your solar system''s size that really determine your installation''s effectiveness. Still, every home is different, and some can benefit from the highest quality panels. If it''s important that you have the "best" solar panels, efficiency, power output, and ability to perform in warm temperatures are all important. You''ll also want to choose panels from a company that backs its panels (and ideally your entire system) with a strong warranty.
Choosing the highest quality solar panels will likely mean a higher upfront cost, but it''s often worth it in the long run. With higher output, efficiency, and longer lifespans, solar panels from the following five brands will maximize your savings:
SunPower lost its exclusivity with its longtime manufacturer in 2024. Maxeon (also one of the best solar panel brands) still currently manufactures SunPower''s highest-quality line of solar panels (the M-Series), but is now able to sell these panels to other U.S. solar panel companies.
REC is a European-based solar company that offers a range of solar panels. Its newest series, the Alpha Pure-R, has an impressive temperature coefficient compared to other panels at 0.24%/°C, making them the best choice if you live in a consistently hot area. The Alpha Pure-R panels are the second most efficient panels on our list at 22.3% efficiency. REC offers a strong bang for the buck at an average of $2.68/W. With black cells, frames, and back sheets, they also blend in nicely with most asphalt shingled and metal roofs.
Panasonic is most commonly known in the U.S. as a TV and small appliance manufacturer, but the Japanese company is also a global leader in solar panels. In 2021, Panasonic began outsourcing its solar panel manufacturing to third-party companies, but panels with Panasonic''s name on them continue to uphold the same standards for quality workmanship and high efficiency. They also still include a 25-year warranty. Panasonic panels are the smallest on our list at just 19.9 sq ft, making them a great choice if you have an awkward roof with tight spaces.
As we mentioned before, Maxeon is the company behind SunPower''s highly efficient and power-dense M-Series solar panels. Maxeon offers an industry-leading warranty, guaranteeing its solar panels will produce 88.25% of their original output at year 40. That''s 15 years longer than traditional solar performance warranties.
Maxeon''s own line of solar panels doesn''t perform quite as well as SunPower''s, but its panels cost about 9% less. It''s also possible that Maxeon will start offering the highest-performance panels soon since their exclusive relationship with SunPower ended in April 2024.
Jinko Solar may have the lowest power per square foot of the top five panels on our list, but when you consider cost, they offer the best value in the market. At over 22% efficiency for their highest quality panels and an average cost of $2.82/W, Jinko panels are a great deal. Just keep in mind that they''re a bit larger than the other panels, so they might not work as well for installations on smaller roofs.
To determine which solar panels are best, we evaluate thousands of solar panel models from hundreds of manufacturers quoted through the EnergySage Marketplace. Here''s how we compare them:
All of the best solar panels on our list include premium monocrystalline solar cell technology. Monocrystalline solar cells are made from a single crystal of silicon instead of many silicon fragments melted together, like in polycrystalline cells.
Single crystal cells convert sunlight to electricity more efficiently than those made with silicon fragments, making monocrystalline solar panels more efficient than polycrystalline solar panels. Monocrystalline panels are typically black and have a higher price tag, whereas polycrystalline cells are blue and more affordable. A few installers still carry polycrystalline panels for home systems, but the price advantage is minimal compared with monocrystalline panels, and the differences in performance and lifespan make monocrystalline panels the clear choice.
The best way to assess a solar panel''s performance is to look at its power output and efficiency. Power output refers to the amount of electricity a solar panel generates under standard test conditions. Efficiency measures how well solar panels convert sunlight into electricity. To rank our solar panels, we primarily looked at power output per square foot. This metric is the best way to directly compare solar panels side-by-side since they can vary so much in size.
Solar panels are like most other electronic equipment: They operate most efficiently in cool temperatures (ideally around 25° C or 77° F). A solar panel''s temperature coefficient measures how much or how little its production drops in hot temperatures. The lower its temperature coefficient, the better it will perform.
For every degree above 25° C (or 77° F), your solar panel''s electricity production will decrease by the temperature coefficient. For example, if your panel''s temperature coefficient is 0.35%/°C, for every one-degree temperature increase above 25°C (77°F), its electricity production will decrease by 0.35%. If its temperature rises to 35°C (95°F), its electricity production will drop by 3.5%.
A solar energy system is a significant investment. Choosing a solar panel with a strong warranty is one of the best ways to feel confident that your system will pay off in the long run.
Your solar panel''s product warranty (sometimes called the materials or equipment warranty) guarantees the manufacturer will replace your panel if it fails due to manufacturing defects or environmental issues within a specific timeframe. Today, most solar panels come with a 25-year product warranty.
A performance warranty guarantees that your panels will produce a certain percentage of their original output by a specified warranty term. Most solar panels offer performance warranties above 80% by year 25. The best are around or above 90%.
You may also see labor included in your solar panel''s warranty. The conditions of a labor warranty vary significantly from brand to brand and will likely depend on you choosing an installer that your solar panel company authorizes. It''s also possible that your installer will offer their own workmanship warranty covering labor components should one of your panels fail.
