A solar panel system for a typical LA home costs 15 to 30 thousand dollars before the 30 percent federal tax credit. After credit: 10.5 to 21 thousand. The system pays for itself in 5 to 7 years through electricity savings.
Average LA home (2,000 sqft): 6-8 kW system. High-usage home (EV, pool, ADU): 10-12 kW. Calculate: review your LADWP bill for annual kWh usage, then size the system to cover 80-100% of consumption. LA gets 5.5 peak sun hours per day — one of the best solar locations in the US. A 7 kW system produces ~11,500 kWh/year.
System cost: $2.50-$3.50/watt installed. 7 kW system: $17,500-$24,500. Federal ITC (30% tax credit): saves $5,250-$7,350. Net cost: $12,250-$17,150. LADWP may offer additional rebates (check LADWP.com). Some LA neighborhoods have community solar programs. Financing: solar loans at 4-7% with $0 down available.
Net metering: excess solar energy flows to the grid, spinning your meter backward. You receive credits at the retail electricity rate. At night: you draw from the grid using your credits. Annual true-up: if you generated more than you used, LADWP pays you (at a lower wholesale rate). Goal: size your system so annual production ≈ annual consumption.
South-facing roof: optimal (gets the most sun in LA). West-facing: 85-90% as effective (captures afternoon sun — good for time-of-use rate optimization). East-facing: 80-85% effective. North-facing: not recommended. Shade: any shade on panels reduces the entire system's output (microinverters mitigate this). Roof condition: install on a roof with 10+ years of life remaining — replacing a roof under solar panels costs $2K-$4K extra for panel removal/reinstall.
Tesla Powerwall, Enphase IQ, or LG RESU: $10K-$15K installed per battery (13-16 kWh capacity). Powers your home during outages and optimizes time-of-use rates (store cheap solar energy, use it during expensive peak hours). ROI on batteries alone: 8-12 years. ROI on solar + battery combo: 6-8 years. Batteries are becoming standard in new LA solar installations.
