Off Grid Solar Power – How to Calculate Your Needs. Warning: Math and physics are involved!


Thinking of getting an off-grid solar powered system? As these guys will show you on their camper van roof, you need to work out the electrical load that will meet all your needs. You’re going to need to do some research into output wattage. Which might involve some basic math. Wattage = amps x voltage. Well, don’t let me spoil it for you. Watch this excellent video and learn just how much power you’re going to need.

Once you have the total, remember to look very closely at your solar power generator to see how much output it claims to provide. Some of them really don’t give as much power as you need.
