I have a massive array+battery (20kWh generation, 19kWh storage) and while it's great, some things to pay consider:
- if you need roof repair/replacement, do it before you get solar. Alternatively, make your array free standing
- prioritize the circuits you want to cover. Not every one is critical but health & safety (water, fridge, cooking capabilities) are key
- MOST jurisdictions won't require permitting for the grid (especially if it's not connected to your house) but MOST will require an inspection if you want to connect to the grid
- if you connect to the grid, make sure you understand how your electricity provider addresses net metering. I wrote about it here: https://geekamongthetrees.com/what-is-solar-net-metering-or-...
