Solar panels in Presque Isle, ME
Roofs in Presque Isle get about 1,329 hours of usable sunlight a year — less than 91% 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 Presque Isle → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Presque Isle solar system costs
A 24-panel system (9.6 kW) is about right for an average Presque Isle home using 10,800 kWh a year. It would produce roughly 10,845 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,615 | $6,384 | $896 | 7.1 yrs |
| 12 panels | 4.8 kW | 5,422 | $9,576 | $1,345 | 7.1 yrs |
| 16 panels | 6.4 kW | 7,230 | $12,768 | $1,793 | 7.1 yrs |
| 20 panels | 8 kW | 9,037 | $15,960 | $2,241 | 7.1 yrs |
| 26 panels | 10.4 kW | 11,748 | $20,748 | $2,737 | 7.6 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 Presque Isle gets 1,329 sun hours
That figure comes from Google's analysis of real rooftops across Presque Isle — 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 Presque Isle reaches about 1,376 hours, roughly 4% better than typical.

When Presque Isle actually produces
Annual totals hide the thing that catches people out: 39% of Presque Isle's yearly sunlight arrives in May–July, and just 11% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 48 | |
| Feb | 72 | |
| Mar | 104 | |
| Apr | 140 | |
| May | 168 | |
| Jun | 180 | |
| Jul | 174 | |
| Aug | 151 | |
| Sep | 117 | |
| Oct | 81 | |
| Nov | 53 | |
| Dec | 42 |
That is a severe seasonal swing — Presque Isle produces roughly 4.3× as much in Jun as in Dec. A system sized to cover your annual usage will overproduce badly in summer and fall well short in winter, so how your utility credits exported power matters more here than in most places.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Presque Isle's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Presque Isle compares to the other 673 cities
| Measure | Presque Isle | Rank of 673 |

| Usable sunlight | 1,329 hrs | 613th |
| Sunlight lost to shade | 3% | 511th most |
| Median roof size | 96 m² | 642nd largest |

| Payback | 7.1 yrs | 42nd fastest |
| Grid carbon | 445 kg/MWh | 533rd dirtiest |
What actually stands out about Presque Isle:
- Roof space is the binding constraint. A typical Presque Isle roof fits about 34 panels and a typical home needs 24 — so there is little room to oversize. If you add an EV or heat pump later, plan the array for it now.
- Small roofs. The median Presque Isle roof is 96 m², smaller than 95% of cities measured — worth checking your own footprint before assuming a standard system fits.
- Older imagery. Google's aerial capture of Presque Isle dates from 2020. Tree growth and new construction since then are not reflected.

Presque Isle solar questions
How many solar panels do I need in Presque Isle?
About 24 panels for an average home using 10,800 kWh a year. Presque Isle roofs get 1,329 usable sun hours, so each 400W panel produces roughly 452 kWh annually. A typical Presque Isle roof fits about 34 panels, so check your usable roof area before assuming that many will fit.
Is solar worth it in Presque Isle?
At 24.8¢/kWh and 1,329 sun hours, a typical system pays for itself in about 7.1 years and returns roughly $47,877 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 Presque Isle?
A 9.6 kW system costs about $27,360 before incentives and $19,152 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.
