When it comes to choosing panels for a home solar power system, many people prioritize panel efficiency, which dictates the amount of sunlight the panels can convert to usable energy. High-efficiency panels tend to generate more power, making them more likely to maximize your energy savings over time.
In this guide, I will review the top six most efficient solar panels brands in the clean energy industry you can install on your home and discuss how they compare to other performance metrics. I''ll also take a look at the other panel models available from the companies that manufacture the most efficient solar panels to help you decide if another option might suit you better.
I''ve spent several years researching and writing about solar panels and manufacturers, and I''ve found that the following are the best solar panels with the highest efficiency ratings you can buy for home solar projects:
I should mention that Panasonic panels were hitting efficiency ratings that were higher than some of these options, but the company has since stopped manufacturing its own panels. As such, I''m not including it as a solar panel brand on this list.
Maxeon panels have the highest efficiency you can get in terms of residential solar panels, topping out at an impressive 22.8%. I recommend these panels to anyone who can afford them, which is a serious sticking point, given that they''re one of the most expensive brands available. I do think they''re worth the investment, though.
It''s hard not to choose Maxeon panels as the most efficient since they have a higher efficiency than any other panel on the market. Not only that, but they have stellar degradation rates, which means that efficiency is going to stick around for longer than it would in most other brands. All in all, these combine to make Maxeon panels the most likely to maximize your savings and maintain high efficiency throughout the panel life span.
Maxeon panels also have incredible warranty coverage, with some of the premium models coming with an unheard-of 40-year warranty. That''s nearly double the industry average, which means you not only get maximum performance but also peace of mind that your panels are going to last for decades to come.
The only real downside to Maxeon panels, in my opinion, is that they''re expensive. They average around $3.00 per watt, which is well above what most other panels go for. Compared to some of the more inexpensive brands that sit at $2.50 per watt, that''s an additional $4,500 you''re paying for the premium Maxeon panels. I do think it''s worth it, though.
The only other downside is a minor one: Maxeon only has a few panel models currently available. This isn''t a huge deal, no matter what, but especially if you''re just looking for the most efficient solar panels available.
Maxeon panels come with some of the most appealing warranty coverage in the industry, which includes an unprecedented 40 years of coverage for manufacturer defects and a 40-year power production guarantee, both of which are better than the industry average. After 25 years, Maxeon panels are guaranteed to retain 92% of their starting efficiency, which is far better than the average, which is in the mid-80s.
Maxeon panels are available through the manufacturer''s sister company, SunPower. You can also get Maxeon panels through SunPower Master Dealers and certified installers.
Jinko Solar is based in China and has some of the most affordable solar panels with high efficiency. They''re great for homeowners who want maximum power output on a budget. However, they do have less impressive warranty coverage and other performance specs than most direct competitors on this list.
Jinko''s top-of-the-line panels reach up to 22.54% efficiency, which positions the company as a top competitor for efficiency. While the Tiger Neo panels from Jinko that hit this number aren''t available in the U.S., the top panels from Jinko that are available in America still top out at an impressive 21.13%.
Jinko''s pricing is pretty impressive as well, as it''s one of the only top panel brands with an efficiency of over 21% that comes in at below-average prices per watt. You could pay a few thousand dollars less for a system from Jinko than you would for a system with panels from a similar manufacturer.
Jinko panels also have a below-average temperature coefficient of as low as -0.29%, making them a good option for homeowners in hot climates looking for a high-efficiency but affordable panel brand.
The biggest downside to Jinko panels, in my opinion, is that they only come with a ten-year manufacturer''s warranty. That''s less than half of what most other tier-one manufacturers offer. This calls into question the durability of the panels overall. Unless you''re prioritizing upfront price more than anything else, I''d recommend a different manufacturer overall for this reason.
Another downside is that the degradation rate is worse than most other panels on this list. The first-year degradation is 3%, which is higher than almost every other tier-one manufacturer. The subsequent years'' degradation is 0.55%, which is, again, well above the average. These panels will produce above-average amounts of electricity in the first few years, but over time, they''ll degrade too much, in my opinion, to make them a true competitor in terms of efficiency.
Jinko''s warranty coverage isn''t ideal. Although most of the panels have a 25- to 30-year power production warranty, the degradation rates are above average for most of the panel options. Plus, the manufacturer''s warranty for many of the panels is just 12 years, which is less than half of what most direct competitors provide.
Jinko Solar doesn''t have exclusive relationships with any solar installers, so you should have some options. However, these panels are less popular in the U.S. than most others on this list, so you may have some difficulty finding an installer near you that carries Jinko products.
LONGi is the largest solar panel manufacturer in the world and for good reason. Its panels are highly reliable and durable, so although the warranty coverage isn''t the best, countless customers rely on them and get peace of mind from the fact that they perform well and usually for decades.
