Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Austin. Keep in mind that 41 kWh is an annual average — summer air conditioning or winter heating can push daily usage well above this in Austin.
Your actual usage may differ from the 41 kWh/day average for Austin — checking your electricity bills or smart meter data gives a more accurate starting point for solar sizing.
Typical energy usage per person per day in Austin:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 10.8kW of solar capacity. With limited roof space, higher-efficiency panels can help you reach the 16.2kW to 21.6kW sweet spot using fewer panels.
A 16.2 kW solar array in Austin delivers approximately 71.0 kWh daily, with generation varying seasonally from 3.61 kWh/kW/day in December up to 4.85 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 Austin
Solar Battery Sizing
At around 50% self-sufficiency without a battery, you're still buying 50% of your electricity from the grid — mostly in the evenings and overnight when solar isn't generating. A 10 kWh battery storage system can raise your energy independence to approximately 72% annually, lowering grid reliance to 28%.
Local incentives and rebates can significantly improve battery economics — check what's available in Austin and use the Photonik design tool to factor them into your calculations.

Solar & Battery System Cost Austin
Understanding Solar & Battery System Costs
Expect to invest approximately $22,608 for a 16.2 kW solar system in Austin, or around $35,328 with a 10 kWh battery included. Solar installations typically pay for themselves within around 8.8 years, whilst batteries extend payback but deliver significantly higher energy independence.
For the most accurate pricing, use the full Photonik design tool — it accounts for your specific roof, local installer pricing, and available rebates in Austin.
ITC Rebates Austin
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.
