Where To start?

All journeys must have a beginning. A good place to start with your adventure into Solar power in general is Utube. You do not need to reinvent the wheel. Benefit fully from other peoples experiences, but try hard to find multiple people saying the same thing.

I will try to help in this adventure by sharing my favorite content.

Another good place to start is to come up with your own personal Use case, knowing what you want to do with Solar will help make the project a success.
