Nothing will motivate a man to move forward faster than knowing what's behind Him.

The Solar Energy Equation

power needed x 2 = inverter power

if you needed 250 watts

250 X 2 = 500

500 would be your inverter power

inverter power / 500 = batteries @ 100ah

500 / 500 = 1 battery @ 100am

if your inverter power was 750-1000 watts you would want 2 batteries @ 100ah

if your inverter power was 2000 watts you would want 4 100ah batteries.

solar panels =  90 watts x 100ah batteries

if you had 1 100ah battery you would want 90 watts of solar panels to be useful  

keep in mind that 15 watts = approx. 1 amp.   an ideal charging rate is 10 amps which is about 150 watts.  

if you had 2 100ah batteries you would want 180 watts of solar panels.

Don’t get me wrong, you can have a 45 watt solar panel system but don’t let your battery go flat 11.9 volts you will be days on end to top off your 100ah battery

 

The ideal beginner solar system would be 500 watt inverter, 1 100ah battery and 90 watts of solar panels.
