Solar Design San Antonio
Energy Usage
To choose the right solar system in San Antonio, start by understanding your daily electricity consumption. 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 Antonio:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 10.5kW of solar capacity. Sizing your system between 15.8kW and 21.1kW accounts for daily and seasonal variations in solar generation.
A 6.6 kW solar array in San Antonio delivers approximately 29.0 kWh daily, with generation varying seasonally from 3.65 kWh/kW/day in December up to 4.86 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 Antonio
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in San Antonio, depending on your consumption patterns, drawing 50% from the grid. Adding a 10 kWh battery increases energy independence to approximately 66% annually, reducing grid reliance to 34%.

Solar & Battery System Cost San Antonio
Understanding Solar & Battery System Costs
Solar systems in San Antonio are priced around $10,945 for a 6.6 kW installation, rising to approximately $15,481 when including a 10 kWh battery. Most solar-only systems reach payback in approximately 6.2 years, though battery storage lengthens payback periods whilst substantially boosting 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 Antonio
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.
