Comparative and performance tests on different photovoltaic solar panels. Comparative by Photon Labs, a German laboratory between 2006 and 2007. Posted in September 2007.
This comparison compares 10 models photovoltaic solar panels (ranked in decreasing order of performance): Photowatt PW1650, Solarworld SW 210 Poly, Shell Solar SQ 150-C, BP Solar BP 7185 S, Solar Fabrik SF 145A, Isofoton I-110 / 24, Kyocera KC 170GT-2, Sunways MHH plus 190, Sanyo HIP-J548E2 and Sharp NT-R5E3E.
For each model, 3 copies were tested between August 2006 and July 2007 according to different criteria, the energy produced being obviously the main of these criteria.
