Measuring Your Solar Needs – An Easy and Low Cost Method

I think the traditional approach of making sure you had enough battery and solar to cover your needs was largely because it was so expensive. You see a lot more people building larger systems simply because we can afford them. 24v panels are inexpensive per watt, telecom batteries are everywhere and some of those no name MPPT chargers are holding their own. You don't have to JUST get by anymore if you are lucky and have access to the gear.

The gear also weighs so you might stay mindful of your CCC.
