Solar panels in Auburn, AL
Roofs in Auburn get about 1,609 hours of usable sunlight a year — more than 59% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.
Check your specific roof in Auburn → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Auburn solar system costs
A 20-panel system (8 kW) is about right for an average Auburn home using 10,800 kWh a year. It would produce roughly 10,941 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,376 | $6,384 | $678 | 9.4 yrs |
| 12 panels | 4.8 kW | 6,565 | $9,576 | $1,018 | 9.4 yrs |
| 16 panels | 6.4 kW | 8,753 | $12,768 | $1,357 | 9.4 yrs |
| 20 panels | 8 kW | 10,941 | $15,960 | $1,679 | 9.5 yrs |
| 26 panels | 10.4 kW | 14,224 | $20,748 | $1,807 | 11.5 yrs |
Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.
Why Auburn gets 1,609 sun hours
That figure comes from Google's analysis of real rooftops across Auburn — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Auburn reaches about 1,666 hours, roughly 4% better than typical.

When Auburn actually produces
Annual totals hide the thing that catches people out: 33% of Auburn's yearly sunlight arrives in May–July, and just 16% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 86 | |
| Feb | 107 | |
| Mar | 133 | |
| Apr | 158 | |
| May | 175 | |
| Jun | 180 | |
| Jul | 177 | |
| Aug | 164 | |
| Sep | 142 | |
| Oct | 115 | |
| Nov | 91 | |
| Dec | 80 |
Output is unusually steady — only about 2.3× between Jun and Dec. Auburn is close enough to the equator that seasonal variation is mild, which makes sizing a system considerably more predictable.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Auburn's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Auburn compares to the other 673 cities
| Measure | Auburn | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,609 hrs | 273rd |
| Sunlight lost to shade | 3% | 510th most |
| Median roof size | 305 m² | 115th largest |
| Electricity rate | 15.5¢ | 226th highest |
| Payback | 9.5 yrs | 308th fastest |
| Grid carbon | 663 kg/MWh | 299th dirtiest |
What actually stands out about Auburn:
- Plenty of roof to work with. Typical roofs here fit around 84 panels — roughly 4× what an average home needs. Roof size will not be what limits your system in Auburn.
- Older imagery. Google's aerial capture of Auburn dates from 2021. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Auburn's 1,609 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.

Auburn solar questions
How many solar panels do I need in Auburn?
About 20 panels for an average home using 10,800 kWh a year. Auburn roofs get 1,609 usable sun hours, so each 400W panel produces roughly 547 kWh annually. A typical Auburn roof fits about 84 panels, so roof space is unlikely to be your limit.
Is solar worth it in Auburn?
At 15.5¢/kWh and 1,609 sun hours, a typical system pays for itself in about 9.5 years and returns roughly $26,027 over a 25-year panel life. That is a solid return, and it improves further if electricity prices rise. Exported power earns full retail credit here.
How much do solar panels cost in Auburn?
A 8 kW system costs about $22,800 before incentives and $15,960 after the 30% federal tax credit. That works out near $2.85 per watt installed. Roof pitch, shading, electrical panel upgrades and equipment choice move the price most, which is why quotes for the same house can differ by thousands.
