Based in Oslo and with its factory in Singapore, REC (Renewable Energy Corp) has the 8th largest market share of all solar panel manufacturers. And REC is a fully integrated manufacturer, which means every component for their solar panels is made in-house, with none of the process outsourced.
In a 2011 trial, Photon Magazine found REC to be the best performing solar panels, generating an average of 6% more electricity than other polycrystalline, monocrystalline and thin film panels tested.
REC solar panels also have an exceptional temperature coefficient of -0.40%, meaning they outperform most other panels in hot conditions. They also have four bypass diodes rather than the standard three, for better performance in shade and low light.
REC solar panels come with a 25 year linear performance warranty, and if you have them installed by Keen 2B Green you’ll receive an industry-leading 12 year product warranty instead of the standard 10 year warranty. That’s how highly we rate this product at Keen 2B Green.
