12V SOLAR PANEL 20W, 36 CELL,10 WATTS WITH CHARGER/CHARGE IN INDIA

It is important to verify the wattage of any panel based on datasheet before considering a purchase. Here are the Simple Tests to confirm Wattage for 12v applications with PWM Solar charge controller before you order;   Test1:    Number of Cells, If it is 36 –  OK Test2:    Ask Vmp. If it is a fixed value between 17v to 18v -  OK  (Because  e ach cell is supposed to be approximately 0.5V) Test3:    Ask Imp.  If it is fixed value between   to A for 20Watt Panel. - OK Test4:    Multiply Vmp with Imp. If it comes to 20W  –  OK (i.e. 17V X Amp = 20 Watt or 18V X Amp = 20Watt) 20 W panel is 36 cell, Vmp of 17V-18V, Imp of A-Amp and 17V X Amp = 20 Watt, and 18V x Amp = 20 Watt Solar Charger Controller 12V/6A PWM Solar Charge/Charger Controller with Mobile Charger 2yr warranty Series solar charge controllers are used
