Solar Design San Jose
Energy Usage
How much energy your San Jose home uses daily directly impacts the solar system size you'll need. 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 Jose:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A solar system sized at approximately 10.5kW would cover your typical daily energy needs. Optimal sizing ranges from 15.8kW to 21.1kW to accommodate daily and seasonal generation variations.
Expect around 27.9 kWh daily from a 6.6 kW system in San Jose, with production varying from 3.23 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 Jose
Solar Battery Sizing
A 6.6 kW solar-only setup in San Jose delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. A 10 kWh battery storage system can raise your energy independence to approximately 63% annually, lowering grid reliance to 37%.

Solar & Battery System Cost San Jose
Understanding Solar & Battery System Costs
A 6.6 kW solar system in San Jose costs approximately $10,945, while adding a 10 kWh battery increases the total to around $15,481. Most solar-only systems reach payback in approximately 6.3 years, though battery storage lengthens payback periods whilst substantially boosting 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 Jose
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.
