Is $68,900 to install a 15.48 kW solar system with battery storage a fair price?
Project Details
I got this quote for a solar installation in Los Angeles (LADWP) and wanted to get some thoughts. We have an older system (24 panels + single inverter) already, and the quote includes $4,320 for removal of that system, though we're keeping the old system. I'm targeting 26,068 kWh annual production, which is about 124% offset, as I wanted plenty of buffer for the future (we calculated around ~21,000 kWh annual consumption). The system integrates with Tesla's monitoring. My major concern is charging our cars; we have 3 EVs + 2 Tesla Universal Wall Connectors and often charge two cars simultaneously. Looking through my Tesla app, the peak single-day consumption for charging was 132 kWh. I think we can configure them to charge on solar and never charge from the battery, but I will continue looking into this and would love any pointers people have!
