Solar Design San Diego
Energy Usage
The right solar system size for your San Diego property depends on how much electricity you use each day. Typical homes consume approximately 40 kWh daily on average, though well-insulated properties with efficient appliances often use significantly less.
Before installing solar it is often a good investment to first look to reduce your energy consumption where possible. This can be done through improved insulation, and energy efficient appliances.
Typical energy usage per person per day in San Diego:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 10.5kW solar system would typically cover your average daily electricity consumption. For best results, size your system between 15.8kW and 21.1kW to account for fluctuations in solar output throughout the day and year.
A 6.6 kW system in San Diego generates approximately 28.6 kWh daily on average, with seasonal variation from 3.50 kWh/kW/day in December to 4.83 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 San Diego
Solar Battery Sizing
Solar-only systems in San Diego typically provide 50% self-usage with a 6.6 kW installation, meaning 50% of your electricity still comes from the grid. Installing a 10 kWh battery boosts your energy independence to around 65% per year, cutting grid dependency down to 35%.

Solar & Battery System Cost San Diego
Understanding Solar & Battery System Costs
Solar systems in San Diego are priced around $10,945 for a 6.6 kW installation, rising to approximately $15,481 when including a 10 kWh battery. Payback periods for solar-only installations average approximately 6.2 years, whilst battery storage extends payback but significantly improves energy independence.
The cost breakdown shows estimates for equipment costs, installation labour, and applicable taxes. Adjust system size and battery storage to see how it affects total investment and payback periods.
ITC Rebates San Diego
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.
