Open circuit voltage(Voc): 21.6V. 4.5m cable with Anderson power connector at 2 ends. Short circuit current(Isc): 7.26A. 0.5m Cable with Anderson style plug and Alligator Clips. Solar panels strengthen by PCB stiffness backer sheet.Light-weighted, and easily set up! Convenient to carry, totally portable for camping, outdoor use. Do not wire the flexible solar panels in series to avoid damage or shortened lifespan. A brief calculation for solar panel with the formulation: EAD = B + SAD8. D Days the system can work without external input. B The capacity of battery, for example 140AH. EA The Amps usage of furniture, assume a Stereo (7.5A), Kettle (2A), TV(12A) and Fridge 40L (24A), 50L(32A), 60L(40A) , 80L(48A) or 100L (56A). SA The Amps provided by solar panel (Can be found from the parameters of solar panel). Then to get the solar panel needed for a certain days holiday.
SA = (EAD-B)/(8D). To get how many days the system can work based on a solar system. You have a 100AH battery, 80L Fridge and you plan a 5 days holiday, the current of the solar system should be. SA = (69.55-100)/(85) = 6.2 A. With 20% margin, the current should be 7.4, and the system needs to be 140W.Example 2: You have a 100AH battery, 100L Fridge and 160W solar system, then the days your system can support will be. D = 100/(77.5 8 8.6)=11.5. Considering around 20% margin, your holiday can be 9 to 10 days without worrying power system.
