Solar & Battery Installation Houston Local Installers & Quotes
Design solar and battery systems for Houston using Photonik's professional design platform. Houston's strong sunshine and competitive electricity market make rooftop solar a smart investment. As Texas' largest city, Houston has seen growing solar adoption, with homeowners benefiting from property tax exemptions and competitive installer pricing.
Solar Design Houston
Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Houston. Energy consumption patterns vary widely in Houston, but 43 kWh per day is a useful starting point for comparing solar system sizes and expected savings.
Every kWh you save through efficiency improvements is worth real money — and also means you need fewer solar panels to cover your remaining usage.
Typical energy usage per person per day in Houston:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 11.3kW system covers average consumption, but sizing slightly larger can help offset seasonal dips and future increases in usage from EVs or heat pumps. The 17.0kW to 22.6kW range accounts for real-world conditions — cloudy days, seasonal variation, and the fact that panels rarely perform at peak all day.
Over a full year, a 17.0 kW system in Houston generates around 27,249 kWh — enough to significantly offset a household using 43 kWh per day.
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 Houston
Solar Battery Sizing
Solar-only systems in Houston typically provide 50% self-usage with a 17.0 kW installation, meaning 50% of your electricity still comes from the grid. A 10 kWh battery makes the most difference in winter when daylight hours are shorter — helping maintain closer to 71% self-sufficiency year-round rather than just in summer.
The gap between December and April production affects how much work your battery does season to season — the full Photonik tool models this for your specific situation.

Solar & Battery System Cost Houston
Understanding Solar & Battery System Costs
At around $23,520 for a 17.0 kW system in Houston, solar is one of the best home investments available — especially with electricity costs continuing to rise. Solar systems typically achieve payback in around 8.7 years, whilst adding battery storage extends the payback period but provides greater energy independence.
The breakdown covers equipment, installation, and taxes. Adjust the system size and battery sliders to see how different configurations affect your investment and payback timeline.
ITC Rebates Houston
The federal Investment Tax Credit (ITC) for residential solar ended on December 31, 2025. To have qualified, the system had to be installed and operational by that date. Large-scale and commercial solar credits follow different rules.
Many states and local utilities still offer 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. Check your state energy office and utility for current programs.
