Solar panels in Aberdeen, WA
Roofs in Aberdeen get about 1,232 hours of usable sunlight a year — less than 97% 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 Aberdeen → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Aberdeen solar system costs
A 26-panel system (10.4 kW) is about right for an average Aberdeen home using 10,800 kWh a year. It would produce roughly 10,891 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,351 | $6,384 | $379 | 16.9 yrs |
| 12 panels | 4.8 kW | 5,027 | $9,576 | $568 | 16.9 yrs |
| 16 panels | 6.4 kW | 6,702 | $12,768 | $757 | 16.9 yrs |
| 20 panels | 8 kW | 8,378 | $15,960 | $947 | 16.9 yrs |
| 26 panels | 10.4 kW | 10,891 | $20,748 | $1,223 | 17 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 Aberdeen gets 1,232 sun hours
That figure comes from Google's analysis of real rooftops across Aberdeen — 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 Aberdeen reaches about 1,255 hours, roughly 2% better than typical.

When Aberdeen actually produces
Annual totals hide the thing that catches people out: 39% of Aberdeen's yearly sunlight arrives in May–July, and just 11% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 44 | |
| Feb | 66 | |
| Mar | 96 | |
| Apr | 130 | |
| May | 156 | |
| Jun | 167 | |
| Jul | 162 | |
| Aug | 140 | |
| Sep | 109 | |
| Oct | 75 | |
| Nov | 49 | |
| Dec | 38 |
That is a severe seasonal swing — Aberdeen produces roughly 4.4× 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 Aberdeen's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Aberdeen compares to the other 673 cities
| Measure | Aberdeen | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,232 hrs | 655th |
| Sunlight lost to shade | 2% | 624th most |
| Median roof size | 185 m² | 403rd largest |
| Electricity rate | 11.3¢ | 626th highest |
| Payback | 17 yrs | 642nd fastest |
| Grid carbon | 696 kg/MWh | 279th dirtiest |
What actually stands out about Aberdeen:
- Unusually open roofs. Only 2% of available sunlight is lost to obstruction in Aberdeen — better than all but 49 of the 673 cities measured. Most roofs here get close to their theoretical maximum.
- Cheap electricity is the headwind. Washington power costs about 11.3¢/kWh. Low rates are good news generally, but they lengthen solar payback — there is simply less bill to displace.
Cities with almost the same sunlight
These are the closest matches to Aberdeen's 1,232 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 |
|---|---|---|---|
| Bradford, PA | 1,226 | 18.1¢ | 10.6 yrs |
| Grande Prairie, AB | 1,250 | 18.1¢ | 15.1 yrs |
| Kailua-Kona, HI | 1,253 | 42.1¢ | 4.5 yrs |

Aberdeen solar questions
How many solar panels do I need in Aberdeen?
About 26 panels for an average home using 10,800 kWh a year. Aberdeen roofs get 1,232 usable sun hours, so each 400W panel produces roughly 419 kWh annually. A typical Aberdeen roof fits about 68 panels, so roof space is unlikely to be your limit.
Is solar worth it in Aberdeen?
At 11.3¢/kWh and 1,232 sun hours, a typical system pays for itself in about 17 years and returns roughly $9,826 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 Aberdeen?
A 10.4 kW system costs about $29,640 before incentives and $20,748 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.
