At $3.00 a watt, the median price cash buyers pay nationally, a 4.6 kW system costs about $13,800. Quotes in Santa Fe will usually fall between $11,500 and $17,250. Complex roofs, main-panel upgrades and financing push prices up.
The 30% federal tax credit no longer applies to systems homeowners buy. This estimate includes no state or utility incentives; check with your utility before you buy.
The number that decides whether solar pays in Santa Fe is what your utility pays for the power you send back. Under full payback is about 11.0 yrs. Under net billing it is about 18.3 yrs, because only the ~42% of solar a typical home uses as it is made saves the full retail price.

The best angle and direction for panels in Santa Fe
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,779 |
| Southeast | 95% | 1,690 |
| Southwest | 95% | 1,690 |
| East | 82% | 1,459 |
| West | 82% | 1,459 |
| North | 58% | 1,032 |
Face panels south and tilt them 35° for the most energy over a year. East and west roofs keep about 82% of that. A north-facing roof keeps 58%, which is rarely worth the money. Try other angles.
Where the sun goes over Santa Fe
The noon sun is lower in winter, which is why the best winter tilt (61°) is steeper than the best summer tilt (6°).
Santa Fe's homes
Santa Fe has 41,921 households. 63.6% own their home, and 22,512 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1986. Many roofs that age are due for replacement. Replace the roof first, then add solar: taking panels off and putting them back later costs thousands.
20.7% of homes heat with electricity and 74.9% with gas. If you switch to a heat pump or an electric car, plan for more panels or leave room on the roof.

6.4 a day on panels tilted to 35°, and 5.5 on flat ground. The best month is Apr; the weakest is Dec.
What is the best angle for solar panels in Santa Fe?
35° for the most energy over a year, facing south. 61° is best in winter and 6° in summer. On a normal pitched roof, anything within 15° of 35° gives you about 95% of the maximum.

A Tesla Powerwall 3 running a fridge, freezer, furnace fan, lights, Wi-Fi, TV and microwave (6.9 kWh a day) lasts about 43 hours with no sun. With 7 kW of solar to recharge it, it gets through a three-day outage even in overcast January.

Snow: NASA records about 12 cm of snow on the ground here in an average January. Covered panels make little until it slides off, and these figures (like PVWatts') don't subtract that.
