About REC solar panels

REC are a polycrystalline cell panel made in Singapore and a very good example of a smaller mainstream brand looking for a point of difference. Their Twin Peak panels takes the usual 60 cells and chops them in half to provide 120 cells on 6 x 20 cell strings. The marketing of the panel says that this design improves performance in the shade and we understand the concept, but there are FAR superior ways to handle shade then this...put an $80 power optimiser on a panel or have a maxim embedded optimiser chip built into the panel. If that means nothing to you, then have a read of the Jinko panel review here.

It has long been said that the upper limit for a polycrystalline 60 cell panel was 290W. Too much heat above that, so the new design with split cells is clearly working as they have a 295W panel. However, as a moncrystalline panel can comfortably achieve 300W+ it would seem that a simpler solution to get greater output would have been to make a mono panel.

The other advantage of this panel is slightly better performance in the heat although the difference in real power production on a typical 6kW residential system is less than 30kW a year or about $10 of power.
