Solar & Battery Installation Los Angeles Local Installers & Quotes
Design solar and battery systems for Los Angeles using Photonik's professional design platform. LA's legendary sunshine makes it one of the best cities in the US for rooftop solar. With California's supportive policies, SGIP battery rebates, and high electricity rates from LADWP and Southern California Edison, solar is an outstanding investment for LA homeowners.
Solar Design Los Angeles
Energy Usage
How much energy your Los Angeles home uses daily directly impacts the solar system size you'll need. If your usage is above 38 kWh per day, switching to efficient appliances, smart hot water, or a pool pump timer can bring you closer to efficient-home levels.
Lowering energy usage before solar installation — via improved insulation and efficient appliances — often reduces required system size and enhances financial returns.
Typical energy usage per person per day in Los Angeles:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Based on 38 kWh daily usage, a 10.0kW system is a good starting point for Los Angeles — though many homeowners choose to install slightly more. With limited roof space, higher-efficiency panels can help you reach the 15.0kW to 20.0kW sweet spot using fewer panels.
Expect around 64.5 kWh daily from a 15.0 kW system in Los Angeles, with production varying from 3.39 kWh/kW/day in December to 4.82 kWh/kW/day in April.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).

Battery Storage Los Angeles
Solar Battery Sizing
At around 50% self-sufficiency without a battery, you're still buying 50% of your electricity from the grid — mostly in the evenings and overnight when solar isn't generating. A 10 kWh battery makes the most difference in winter when daylight hours are shorter — helping maintain closer to 74% self-sufficiency year-round rather than just in summer.
The gap between December and April production affects how much work your battery does season to season — the full Photonik tool models this for your specific situation.

Solar & Battery System Cost Los Angeles
Understanding Solar & Battery System Costs
For Los Angeles homeowners looking to reduce their electricity bills, a $21,240 solar installation can dramatically lower or even eliminate that ongoing monthly cost. Most solar-only systems reach payback in approximately 9.0 years, though battery storage lengthens payback periods whilst substantially boosting energy independence.
Whether you choose solar-only at $21,240 or add a battery at $33,960, the investment is typically recovered well within the system's 25-year lifespan.
ITC Rebates Los Angeles
The federal Investment Tax Credit (ITC) for residential solar ended on December 31, 2025. To have qualified, the system had to be installed and operational by that date. Large-scale and commercial solar credits follow different rules.
Many states and local utilities still offer rebates and incentives. These can include state tax credits, cash rebates, performance-based incentives, and net metering programs that allow you to sell excess solar energy back to the grid. Check your state energy office and utility for current programs.
