If you have a good handle on DC systems and inverters it's not that bad. Hardest part in my experience is figuring things out with your power company if you're staying on grid.
Also at least in the us, check your town and state for rebates and such. A lot of the time these scummy solar companies are double dipping, charging you 20k and also getting a couple k from the gov through solar programs.
Been on graphene for a few months now. Aside from a few apps that are over-reliant on the Google ecosystem, it's works fine. Would recommend. Battery is also a lot better with all the tracking and such removed.
