Solar Design San Francisco
Energy Usage
How much energy your San Francisco home uses daily directly impacts the solar system size you'll need. Whilst typical San Francisco households consume 40 kWh daily, homes with good insulation and modern appliances often use far less energy.
Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.
Typical energy usage per person per day in San Francisco:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
To offset your average consumption, you'd need roughly 10.5kW of solar capacity. Systems sized between 15.8kW and 21.1kW perform best, accounting for natural fluctuations in solar production.
A 6.6 kW system in San Francisco generates approximately 27.8 kWh daily on average, with seasonal variation from 3.21 kWh/kW/day in December to 4.79 kWh/kW/day in August.
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 San Francisco
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in San Francisco, depending on your consumption patterns, drawing 50% from the grid. Adding a 10 kWh battery increases energy independence to approximately 63% annually, reducing grid reliance to 37%.

Solar & Battery System Cost San Francisco
Understanding Solar & Battery System Costs
Solar installation costs in San Francisco start at approximately $10,945 for a 6.6 kW system, with a 10 kWh battery bringing the total to around $15,481. Solar systems typically achieve payback in around 6.3 years, whilst adding battery storage extends the payback period but provides greater energy independence.
Pricing includes equipment, labour, and taxes. Use the sliders to adjust system size and battery capacity, observing how changes impact total cost and payback.
ITC Rebates San Francisco
The Investment Tax Credit (ITC) is a federal tax credit that allows you to deduct a percentage of the cost of installing a solar energy system from your federal taxes. The ITC applies to both residential and commercial solar installations.
Currently, the ITC provides a 30% tax credit for solar systems installed through 2032. This credit applies to the total cost of the solar system, including equipment, installation, and related expenses. The credit can be claimed in the tax year the system is installed and becomes operational.
In addition to the federal ITC, many states and local utilities offer additional 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.
