I put some left-overs in the microwave that the last owner had left, and turned it on. The microwave hummed, and then....silence. The lights went out. We were sitting in total darkness, surrounded by piles of boxes.
This was our introduction to our solar power system.
Oh, for a flashlight! Which box were they in? And...had we damaged anything?
It turns out, we hadn't done any damage- solar systems just don't do well with microwaves- at least ours doesn't. (This works for me, because I don't use microwaves any how) They draw a lot of power- more than the system can handle, unless it's fully charged.
So, here's our set-up:
These are the panels. They commune with the sun and, sort of like a plant, make energy!
(I hope you're OK with a LOW tech explanation...)
The energy gets sent to the batteries, where it's stored.
Then, when we turn on lights, or use any power, the inverter converts the DC power from the batteries to AC power that can run our lights and appliances.
There's a charge controller in there, too. Anybody want to guess what important function it serves?
How much, how fast, and how well all depends on how big your system is. There are a gazillion ways to configure the system, and we found it well worth the expense to pay an expert to help- they have all the tinker toys to be able to make sure the system is streamlined and as efficient as possible.
In the end, we made peanut butter sandwiches and went to bed early, since we were so tired and didn't know how to bring the lights back on anyway. Tomorrow would be solar 101 lesson day.
