Solar panels in Durango, CO
Roofs in Durango get about 1,978 hours of usable sunlight a year — more than 95% 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 Durango → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Durango solar system costs
A 17-panel system (6.8 kW) is about right for an average Durango home using 10,800 kWh a year. It would produce roughly 11,433 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,380 | $6,384 | $796 | 8 yrs |
| 12 panels | 4.8 kW | 8,070 | $9,576 | $1,194 | 8 yrs |
| 16 panels | 6.4 kW | 10,760 | $12,768 | $1,593 | 8 yrs |
| 20 panels | 8 kW | 13,450 | $15,960 | $1,696 | 9.4 yrs |
| 26 panels | 10.4 kW | 17,486 | $20,748 | $1,846 | 11.2 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 Durango gets 1,978 sun hours
That figure comes from Google's analysis of real rooftops across Durango — 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 Durango reaches about 2,075 hours, roughly 5% better than typical.

When Durango actually produces
Annual totals hide the thing that catches people out: 35% of Durango's yearly sunlight arrives in May–July, and just 14% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 95 | |
| Feb | 125 | |
| Mar | 162 | |
| Apr | 199 | |
| May | 225 | |
| Jun | 235 | |

| Aug | 209 | |
| Sep | 175 | |
| Oct | 135 | |
| Nov | 102 | |
| Dec | 87 |
Durango produces about 2.7× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Durango's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Durango compares to the other 673 cities
| Measure | Durango | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,978 hrs | 36th |
| Sunlight lost to shade | 5% | 388th most |
| Median roof size | 468 m² | 11th largest |
| Electricity rate | 14.8¢ | 427th highest |
| Payback | 8.4 yrs | 155th fastest |
| Grid carbon | 770 kg/MWh | 183rd dirtiest |
What actually stands out about Durango:
- Plenty of roof to work with. Typical roofs here fit around 158 panels — roughly 9× what an average home needs. Roof size will not be what limits your system in Durango.
- Large roofs. At a median of 468 m², Durango has the 11th-largest typical roof footprint we've measured.
- Sunnier than the rest of Colorado. Durango roofs get 13% more usable sunlight than the typical Colorado city we've measured — statewide averages will understate what you can expect here.
- Older imagery. Google's aerial capture of Durango dates from 2019. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Durango's 1,978 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.

| Santa Fe, NM | 1,977 | 14.8¢ | 8.4 yrs |
| Riverside, CA | 1,980 | 31.2¢ | 8.2 yrs |

Durango solar questions
How many solar panels do I need in Durango?
About 17 panels for an average home using 10,800 kWh a year. Durango roofs get 1,978 usable sun hours, so each 400W panel produces roughly 673 kWh annually. A typical Durango roof fits about 158 panels, so roof space is unlikely to be your limit.
Is solar worth it in Durango?
At 14.8¢/kWh and 1,978 sun hours, a typical system pays for itself in about 8.4 years and returns roughly $26,979 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 Durango?
A 6.8 kW system costs about $19,380 before incentives and $13,566 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.
