A couple of questions for anyone with knowledge of solar setups (for context we're thinking about a 10-panel setup on our SW-facing roof, to be installed during a full-house refurb):
Is it a no-brainer to get a battery? I'm trying to work out the pros and cons. Storing excess production and running stuff from a battery would obviously reduce kWh used from the grid, but is the extra initial cost, space and general faff worth it? Would a battery pay for itself fairly quickly?
The panels would be split (6:4) between two adjoining staggered roofs that have the same orientation but slightly different pitches. The initial schematic that has been worked up shows a single inverter for all 10 panels. I've read that the output of the entire array can be choked by a single panel being shaded. Is it a better idea to have a separate inverter for each roof or even for every panel?
