I have not yet spent a cent on a pv solar system. I have talked to a lot of people over the past five years. Most of them were not totallyl satisfied - I think the reason is that they did not have proper expectations of what a pv system will do. My suggestion - watch a lot of YT videos on the subject until you can speak "geek" on the subject - join with a local community college or adult ed program to see if they have classes. As part of a prep, you are ultimately the one who has to repair it. I think this is on instance when it is impossible to have too much knowledge.
