New to solar and learning. I have a 100 watt system for a start and it would be desirable to measure how much electricity it is generating as well as how much I am using. Any low cost options? So...
I think that I will try it with just the volt gauge. If I have the same or more every morning, I will be in good shape. If not? Lower usage or up the input. Thanks to all who offered suggestions about the various testers and meters.
