I built 3 Solar Panels (@ 150 wp). It seems worked good on testing. I set it from 36 pcs 6 x 6 inch polycrystalline solar cell to get 18 volt DC (will reach above 20 VDC on strong sunlight). It got more than 18 VDC on limited sun light (under a blue canopy at the morning). Hope got maximum watt output ..
