When it comes to Home Solar panels, there are a few brands that stand out from the rest. Silfab, SunPower, Panasonic, and LG are some of the top contenders in the industry. Each of these companies offers high-efficiency panels with extended warranties and performance guarantees. Silfab Cells tops our list with its high-efficiency passivated emitter and back contact (PERC) panels that have guaranteed performance for 30 years.
Backed by one of the longest extended performance warranties available, Silfab offers high-performance panels at a price just below premium brands. The company promises 83% production of its panels for 30 years and if the panels fall below this level, Silfab will take care of their maintenance or repair. Their panels also include a 12-year labor warranty, which aligns with the industry standard of 10 to 12 years. However, this warranty can be extended to 25 years if homeowners purchase their panels from a SILFAB certified installer.SunPower produces some of the best high-efficiency solar panels on the market today.
Although their panels have the highest price of all the panels in our review, an initial investment in the top solar panels will result in future long-term savings. The company offers a 25-year product and performance warranty, one of the few companies to offer such extended warranties. SunPower also guarantees that its panels will produce at least 92% of the power initially published by Year 25.If its panels fall below this threshold, the company will update its system to restore performance.Panasonic's latest panel series, EverVolt, uses half-cut heterojunction (HJT) solar cell technology to create some of the most energy-efficient panels available. Its panels are made to withstand extreme temperatures, an excellent choice for homeowners in hot climates.
The most powerful panels in the series have efficiencies between 21.6% and 22.2% in options from 400 W to 410 W. The company's 25-year AllGuard and TripleGuard warranty covers EverVolt panels for products, parts, labor and performance. Panasonic also guarantees output performance of at least 92% of its panels for 25 years.LG solar panels are ideal for homeowners with complicated roof designs or limited roof space. Since your panels are more powerful yet compact, you can buy fewer panels and generate enough power for your home.
LG offers three options for residential solar systems. Smaller LG NeOn R 375W has 20.7% efficiency while the company guarantees the power of the 365 W NeON 2 Black solar panel at 90.6% after 25 years. Finally, the LG NeON 2 400W bifacial solar panel employs technology that allows sunlight to be absorbed at the top and bottom of the panel which allows them to continue to collect energy even on cloudy days.LG backs its panels with a 25-year product warranty. However, the energy production guarantee varies by model.
For example, LG NeOn R panels are guaranteed 98.5% production after one year and a minimum of 92.5% in 25 years while LG NeOn 2 series will produce 96.4% of its production at the end of 25 years.When it comes to choosing Home Solar Panels, there is no one size fits all solution as each homeowner has different needs and preferences when it comes to their energy needs and budget constraints. If you are looking for high-efficiency panels that provide the performance of a premium brand without the high price tag, we recommend Silfab as your best choice. Homeowners looking for solar panels that offer a more economical price but high quality performance should look for Q Cells while those looking for panel options on a budget should consider Trina Solar.Overall, SunPower, REC and Panasonic make the best solar panels due to their high efficiency, competitive pricing, and 25-year warranties but there are many more brands worth considering such as Polycrystalline solar panels which tend to have a lower efficiency rate than monocrystalline solar panels but offer good quality and affordable products.When industry experts talk about efficiency of Home Solar Panels they are referring to amount of sunlight that reaches a solar cell that is actually converted into electricity and comparing two experts say that Panasonic solar panels have slight advantage in terms of specifications while LG has small cost advantage.As general rule of thumb less space you have for solar panel more you want to look for high-efficiency panel to get most out of your solar energy system and ultimately choosing right solar system and finding best price on solar panel is unique to every homeowner or business owner interested in solar energy.It seems that California consumers are happy to pay hefty premium to get best Home Solar Panels available but there is no feasible way to perform practical testing after installation so subjective ratings for customer service is important factor in experience when obtaining solar panel for roof.
