Is $12,900 to install a 9.3 kW solar panel system with 10 kW battery and 8 kW inverter a fair price?
Project Details
I'm seeking advice on this quote. My roof faces southwest and can accommodate 20 panels. My annual electricity usage is closer to 6400 kWh, though I rounded it up to 7000 kWh for the quote. I asked about the new Neostar 3s+ - 470W panels, and they said they can provide them, but didn't specify if the price would change. I'm wondering if the quote is overpriced and if I should consider a 10 kWh inverter/controller and 16 kWh of battery storage instead. We discussed a gateway, but it's not very needed in my area as I haven't experienced power cuts since moving here. I am also getting quotes from different companies.
