Production vs. use by month
12,335 kWh/yr
Covers 40% of your use directly; 34% of the output is used on the spot.
1,835 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 | $1,777 | 5.1 years | $45,322 |

Solar in Palm Springs: common questions
Are solar panels worth it in Palm Springs, CA?
For an example 7 kW system costing $21,000 on a home using 10,500 kWh a year, payback in Palm Springs is 5.8 years with full net metering and 7.3 years if exports earn half the retail rate, at the California average price of 33.61¢/kWh (EIA, July 2026).
How much electricity do solar panels produce in Palm Springs?
About 1,762 kWh per year for each kW of south-facing panels at a 20° pitch (NLR PVWatts, typical-year weather), from 112 kWh in Dec to 179 kWh in May.
What size solar system does a home in Palm Springs need?
About 6.0 kW to cover 10,500 kWh a year. Divide your own annual use by 1,762 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 Palm Springs?
Yes. Per kW at a 20° pitch: south 1,762 kWh, southeast 1,665 kWh, southwest 1,719 kWh, east 1,479 kWh, west 1,555 kWh, east-west (split) 1,517 kWh a year. South-facing roofs produce the most; east or west roofs still work, with less output.
