New questions Help with solar ?

[Orchidlandguy]

Anybody use ProVision or know anybody who did?

We are doing a grid tie system.
If we don't go with SunRun/Revoluson they take on all the maintenance. With a grid tie system, is there that much maintenance that it is worth the extra expense to go with them?

Or can someone with no tech or mechanical inclination easily maintain and who do you call to fix and tweak system if you don't go with the folks who take care of the system (sun run)?
Thanks again for all the help.
