Detailed Solar Panel Reviews
SunPower Panel Review
Sunpower, founded in 1985, is the leader in solar panel innovation and produces panels for residential systems to large utility scale products. The company offers the most premium panels in the market in terms of efficiency and warranty and prices are higher than standard panels. Sunpower panels have efficiencies of 19.5% – 21.5%, which means they generate more power and take up less space on your roof (great for projects where roof space is limited). As an example (see here for details), Sunpower’s 360W panel is the same size as a conventional 260W panel, but generates ~40% more power (360W/260W). In addition, Sunpower’s panels lose their power output slower than other panels, so the production over the life of the system ends up being ~60% greater. Another area of differentiation for Sunpower is the Company’s 25-year warranty which is a compelling offer for homeowners that do not want to deal with any hassles if issues come up with the system. The Sunpower warranty is longer (25 years vs. 10-15 years), covers the entire system (vs. individual components/warranties with other panel providers), and will pay for shipping and installation of warranty claims. Note that Sunpower sells its panels through a network of exclusive dealers, so not every local installer will have Sunpower panels. For more information, read the details on the X model (data sheet) and the E-model (data sheet).
LG Electronics Panel Review
LG Solar is the solar division of the large South Korean company that makes everything from mobile devices to washing machines.

LG also offers a black version of its Neon line, which is more aesthetically pleasing and blends into your home better (slightly less efficiency). Following the trend of other module manufacturers, in 2017 LG introduced a version of its Neon panels that is packaged with an Enphase inverter to reduce installation time. LG’s Neon R offer a similar 25 year warranty to match the Sunpower panels, but the other models have a 15-year warranty.
