Solar Panel Review

Editor's Pick
Evergreen Spruce Panel Evergreen's Spruce series is made for grid-tie systems. The reason this system gets Editor's Pick is because of the care taken by Evergreen during the manufacturing process to ensure a low environmental impact. The only gripe we have about it is the relatively short warranty.

Sharp has the only one PV in this review under 190 watts (it is 180-W) but it makes up for it with some great features, such as a 25-year warranty, and built-in bypass diodes. Solar Panels Sharp PVs have a strong name in the industry but for the price we would go with a higher-output solar panel.

At 17.4 percent efficiency, the Sanyo Solar Panels Sanyo is the most efficient photovoltaic module out of the the ones we reviewed. This is because of Sanyo's HIT (heterojunction with intrinsic thin layer) technology, which allows the module to obtain maximum power within a fixed space and a lower temperature de-rating. As the days get hotter, the Sanyo HIT technology allows these photovoltaics to produce more electricity than conventional crystalline silicon solar panels at the same temperature.

The Kyocera Solar Panels Kyocera KC190GT is a very good solar panel for the price and works well in everything from small-scale residential solar power systems to mid-scale commercial projects. Kyocera uses newly developed treatment method processes multi-crystalline silicon cells in order to produce a surface texture that minimizes surface reflectance and maximizes output.
