Solar & Battery Rebates in Texas, United States Incentives & Costs

Energy Usage

Energy consumption patterns in Texas reflect the state's hot climate, with high cooling needs during long, hot summers. The average Texas household uses between 35-45 kWh per day, with higher consumption during summer months for air conditioning. Energy-efficient properties throughout Texas often use significantly less through modern insulation, efficient HVAC systems, and smart thermostats that optimize cooling schedules.

Before installing solar, consider reducing your energy consumption through improved insulation and energy-efficient appliances. This is particularly valuable in Texas, where high summer electricity usage makes reducing consumption a sound investment that can lower required solar system size and improve returns.

Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.

Solar System Sizing

You'll need around 10.5kW of solar to match your average consumption in Texas. We recommend sizing between 15.8kW and 21.1kW for optimal results, accounting for daily and seasonal variations. Texas enjoys excellent solar potential, with most regions averaging 4.5-5.5 kWh/kW/day annually, amongst the highest in the US, with strong generation throughout most of the year.

A 6.6 kW system in Texas generates approximately 28.9 kWh daily on average, with seasonal variation from 3.61 kWh/kW/day in December to 4.85 kWh/kW/day in April. Texas's exceptional solar irradiance, combined with competitive electricity markets and property tax exemptions, makes solar particularly attractive for homeowners across the state.

With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Texas, 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%. Battery storage is valuable in Texas, allowing you to store excess daytime generation for evening use and providing backup power during grid outages, which can be common during extreme weather events.

Texas lacks a statewide net metering policy, but many utilities offer net metering programs with rates varying by utility. Property tax exemptions ensure solar installations don't increase property taxes.

Understanding Solar & Battery System Costs

A 6.6 kW solar system in Texas costs approximately $10,945, while adding a 10 kWh battery increases the total to around $15,481. Texas offers property tax exemptions ensuring solar installations don't increase property taxes, and many utilities provide net metering programs. Solar-only systems typically pay for themselves in around 6.2 years in Texas, whilst adding battery storage usually extends payback but significantly improves energy independence and provides backup power. Texas's combination of excellent solar potential, competitive electricity markets, and property tax exemptions makes solar particularly attractive, with many systems achieving payback in under 7-9 years.
