Solar panels in Reno, NV: payback and output
A kW of south-facing panels in Reno produces about 1,664 kWh a year, 5% less than Las Vegas, the Nevada reference city. Summer months produce 1.8× what winter does. To cover a typical 10,500 kWh/yr home on paper you'd need roughly 6.3 kW.

Production vs. use by month
11,645 kWh/yr
Covers 40% of your use directly; 36% of the output is used on the spot.
1,144 kWh/yr earn no credit. Your credits exceed a year of grid purchases and most utilities don't pay out the excess. A smaller system pays back faster.
Which size pays off best?
Same usage and prices, only size changes. Best 25-year gain: 7 kW.
| Size | Cost | Year-1 savings | Payback | 25-yr gain |
|---|---|---|---|---|
| 3 kW | $9,000 | $637 | 14.3 years | $8,880 |
| 4 kW | $12,000 | $850 | 13.8 years | $12,673 |

Solar in Reno: common questions
Are solar panels worth it in Reno, NV?
For an example 7 kW system costing $21,000 on a home using 10,500 kWh a year, payback in Reno is 14.1 years with full net metering and 18.6 years if exports earn half the retail rate, at the Nevada average price of 12.77¢/kWh (EIA, July 2026).
How much electricity do solar panels produce in Reno?
About 1,664 kWh per year for each kW of south-facing panels at a 20° pitch (NLR PVWatts, typical-year weather), from 87 kWh in Jan to 179 kWh in Jun.
What size solar system does a home in Reno need?
About 6.3 kW to cover 10,500 kWh a year. Divide your own annual use by 1,664 kWh per kW for a first estimate; if exports earn less than retail, a smaller system often pays back faster.
Does roof direction matter in Reno?
Yes. Per kW at a 20° pitch: south 1,664 kWh, southeast 1,607 kWh, southwest 1,584 kWh, east 1,441 kWh, west 1,410 kWh, east-west (split) 1,425 kWh a year. South-facing roofs produce the most; east or west roofs still work, with less output.
