Solar potential in Austin
Austin receives 4.812 kWh/m² per day on a horizontal surface, averaged over 30 years. Tilting panels to 25° raises annual output by 7%.
A typical home system is 5–10 kW. Roughly 15 panels for 6 kW.

Austin sun and solar questions
- How much does daylight change through the year in Austin?
- Austin sits at 30.3° north. Its longest day runs 14h 06m and its shortest 10h 11m — a swing of 3h 55m.
- What angle should solar panels be in Austin?
- 25° from horizontal, facing south, maximises annual production. That is about 7% more than laying panels flat. If you want to favour winter output, 52° is better; for summer, 0°.
- How much power would solar panels produce in Austin?
- About 1,465 kWh per year for every kW installed, at the optimal angle. A typical 6 kW home system would produce roughly 8,792 kWh a year. Jul is the strongest month and Dec the weakest.
- How high does the sun get in Austin?
- At the summer solstice the sun reaches 83.2° above the horizon at solar noon. At the winter solstice it only reaches 36.3°. That difference is what drives both the seasons and the ideal panel angle.
Sun times assume a flat horizon at sea level. Solar figures are long-term climate averages and do not account for shading, roof pitch or local regulations. See the methodology.
