What a typical Parkersburg solar system costs
A 23-panel system (9.2 kW) is about right for an average Parkersburg home using 10,800 kWh a year. It would produce roughly 10,815 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,762 | $6,384 | $538 | 11.9 yrs |
| 12 panels | 4.8 kW | 5,643 | $9,576 | $807 | 11.9 yrs |
| 16 panels | 6.4 kW | 7,524 | $12,768 | $1,076 | 11.9 yrs |
| 20 panels | 8 kW | 9,404 | $15,960 | $1,345 | 11.9 yrs |
| 26 panels | 10.4 kW | 12,226 | $20,748 | $1,595 | 13 yrs |
How we worked this out for Parkersburg
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Parkersburg rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,383 sun hrs × 0.85 system losses |
470 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 470 kWh per panel |
23 panels |
| 3 | System size 23 panels × 400W |
9.20 kW |
| 4 | Annual production 9.20 kW × 1,383 hrs × 0.85 |
10,815 kWh/yr |
| 5 | Installed cost 9,200 W × $2.85 per watt, then −30% federal credit |
$18,354 |
| 6 | Annual saving 3,780 kWh used as generated × 14.3¢ + 7,035 kWh exported × 14.3¢ |
$1,545/yr |
| 7 | Payback $18,354 ÷ $1,545 per year |
11.9 years |
Step 6 matters more than it looks. Only 35% of what a system this size produces in Parkersburg is used the moment it is generated; the other 7,035 kWh is exported and credited one-for-one under net metering. Because exports here are credited at or near retail, that split changes the payback very little — 11.9 years against the 11.9 we show. In places where exports pay a fraction of retail the same split moves payback by years, which is why we model it explicitly rather than assuming.
Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), $2.85/W installed, 10,800 kWh typical annual household use, 14.3¢/kWh electricity. Change any of those and every figure above moves — which is exactly why a single national "solar costs X" number is misleading.
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 Parkersburg gets 1,383 sun hours
That figure comes from Google's analysis of real rooftops across Parkersburg — 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 Parkersburg reaches about 1,555 hours, roughly 12% better than typical.

When Parkersburg actually produces
Annual totals hide the thing that catches people out: 36% of Parkersburg's yearly sunlight arrives in May–July, and just 14% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 63 | |
| Feb | 85 | |
| Mar | 112 | |
| Apr | 141 | |
| May | 161 | |
| Jun | 169 | |
| Jul | 164 | |
| Aug | 148 | |
| Sep | 122 | |
| Oct | 93 | |
| Nov | 68 | |
| Dec | 57 |
Parkersburg produces about 2.9× 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 Parkersburg's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Parkersburg compares to the other 788 cities
| Measure | Parkersburg | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,383 hrs | 568th |
| Sunlight lost to shade | 11% | 48th most |
| Median roof size | 225 m² | 287th largest |
| Electricity rate | 14.3¢ | 551st highest |
| Payback | 11.9 yrs | 522nd fastest |
| Grid carbon | 883 kg/MWh | 70th dirtiest |
What actually stands out about Parkersburg:
- Shading is a real problem here. Parkersburg loses 11% of its potential sunlight to trees, chimneys and neighbouring buildings — the 48th-worst of the 788 cities measured. Panel placement matters more here than in most places, and a roof survey is worth more than a phone quote.
- Every kWh counts more here. The grid serving Parkersburg emits 883 kg CO₂ per MWh, among the highest of the 788 cities measured — so the same panels displace more emissions than they would elsewhere.
- Older imagery. Google's aerial capture of Parkersburg dates from 2021. Tree growth and new construction since then are not reflected.

Parkersburg solar questions
How many solar panels do I need in Parkersburg?
About 23 panels for an average home using 10,800 kWh a year. Parkersburg roofs get 1,383 usable sun hours, so each 400W panel produces roughly 470 kWh annually. A typical Parkersburg roof fits about 77 panels, so roof space is unlikely to be your limit.
Is solar worth it in Parkersburg?
At 14.3¢/kWh and 1,383 sun hours, a typical system pays for itself in about 11.9 years and returns roughly $20,269 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 Parkersburg?
A 9.2 kW system costs about $26,220 before incentives and $18,354 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.
