Solar panels in Logan, UT
Roofs in Logan get about 1,705 hours of usable sunlight a year — more than 69% 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 Logan → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Logan solar system costs
A 19-panel system (7.6 kW) is about right for an average Logan home using 10,800 kWh a year. It would produce roughly 11,014 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,638 | $6,384 | $519 | 12.3 yrs |
| 12 panels | 4.8 kW | 6,956 | $9,576 | $779 | 12.3 yrs |
| 16 panels | 6.4 kW | 9,275 | $12,768 | $1,039 | 12.3 yrs |
| 20 panels | 8 kW | 11,594 | $15,960 | $1,232 | 13 yrs |
| 26 panels | 10.4 kW | 15,072 | $20,748 | $1,329 | 15.6 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 Logan gets 1,705 sun hours
That figure comes from Google's analysis of real rooftops across Logan — 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 Logan reaches about 1,759 hours, roughly 3% better than typical.

When Logan actually produces
Annual totals hide the thing that catches people out: 37% of Logan's yearly sunlight arrives in May–July, and just 13% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 73 | |
| Feb | 100 | |
| Mar | 137 | |
| Apr | 176 | |
| May | 203 | |
| Jun | 215 | |
| Jul | 209 | |
| Aug | 186 | |
| Sep | 151 | |
| Oct | 111 | |
| Nov | 79 | |
| Dec | 65 |
Logan produces about 3.3× 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 Logan's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Logan compares to the other 673 cities
| Measure | Logan | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,705 hrs | 207th |
| Sunlight lost to shade | 3% | 547th most |
| Median roof size | 190 m² | 389th largest |
| Electricity rate | 11.2¢ | 655th highest |
| Payback | 12.5 yrs | 530th fastest |
| Grid carbon | 696 kg/MWh | 267th dirtiest |
What actually stands out about Logan:
- Plenty of roof to work with. Typical roofs here fit around 80 panels — roughly 4× what an average home needs. Roof size will not be what limits your system in Logan.
- Cheap electricity is the headwind. Utah power costs about 11.2¢/kWh. Low rates are good news generally, but they lengthen solar payback — there is simply less bill to displace.
- Older imagery. Google's aerial capture of Logan dates from 2018. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Logan's 1,705 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
| City | Sun hrs | Rate | Payback |
|---|---|---|---|
| Carrollton, TX | 1,705 | 15.1¢ | 9.3 yrs |
| Daytona Beach, FL | 1,704 | 15.3¢ | 9.1 yrs |
| Hattiesburg, MS | 1,707 | 13.3¢ | 10.5 yrs |
| Muskogee, OK | 1,707 | 12.1¢ | 11.5 yrs |

Logan solar questions
How many solar panels do I need in Logan?
About 19 panels for an average home using 10,800 kWh a year. Logan roofs get 1,705 usable sun hours, so each 400W panel produces roughly 580 kWh annually. A typical Logan roof fits about 80 panels, so roof space is unlikely to be your limit.
Is solar worth it in Logan?
At 11.2¢/kWh and 1,705 sun hours, a typical system pays for itself in about 12.5 years and returns roughly $15,228 over a 25-year panel life. That is slower than average, so compare several quotes before committing. Exported power earns full retail credit here.
How much do solar panels cost in Logan?
A 7.6 kW system costs about $21,660 before incentives and $15,162 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.
