What a typical Klamath Falls solar system costs
A 18-panel system (7.2 kW) is about right for an average Klamath Falls home using 10,800 kWh a year. It would produce roughly 11,255 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,002 | $6,384 | $620 | 10.3 yrs |
| 12 panels | 4.8 kW | 7,503 | $9,576 | $930 | 10.3 yrs |
| 16 panels | 6.4 kW | 10,004 | $12,768 | $1,241 | 10.3 yrs |
| 20 panels | 8 kW | 12,505 | $15,960 | $1,392 | 11.5 yrs |
| 26 panels | 10.4 kW | 16,257 | $20,748 | $1,508 | 13.8 yrs |
How we worked this out for Klamath Falls
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Klamath Falls rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,839 sun hrs × 0.85 system losses |
625 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 625 kWh per panel |
18 panels |
| 3 | System size 18 panels × 400W |
7.20 kW |
| 4 | Annual production 7.20 kW × 1,839 hrs × 0.85 |
11,255 kWh/yr |
| 5 | Installed cost 7,200 W × $2.85 per watt, then −30% federal credit |
$14,364 |
| 6 | Annual saving 3,780 kWh used as generated × 12.4¢ + 7,475 kWh exported × 12.4¢ |
$1,353/yr |
| 7 | Payback $14,364 ÷ $1,353 per year |
10.6 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in Klamath Falls is used the moment it is generated; the other 7,475 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 — 10.3 years against the 10.6 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, 12.4¢/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 Klamath Falls gets 1,839 sun hours
That figure comes from Google's analysis of real rooftops across Klamath Falls — 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 Klamath Falls reaches about 1,861 hours, roughly 1% better than typical.

When Klamath Falls actually produces
Annual totals hide the thing that catches people out: 37% of Klamath Falls's yearly sunlight arrives in May–July, and just 13% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 77 | |
| Feb | 108 | |
| Mar | 147 | |
| Apr | 190 | |

| Aug | 201 | |
| Sep | 163 | |
| Oct | 119 | |
| Nov | 84 | |
| Dec | 69 |
Klamath Falls produces about 3.4× 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 Klamath Falls's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Klamath Falls compares to the other 788 cities
| Measure | Klamath Falls | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,839 hrs | 108th |
| Sunlight lost to shade | 1% | 765th most |
| Median roof size | 100 m² | 704th largest |
| Electricity rate | 12.4¢ | 659th highest |
| Payback | 10.6 yrs | 387th fastest |
| Grid carbon | 696 kg/MWh | 272nd dirtiest |
What actually stands out about Klamath Falls:
- Unusually open roofs. Only 1% of available sunlight is lost to obstruction in Klamath Falls — better than all but 23 of the 788 cities measured. Most roofs here get close to their theoretical maximum.
- Sunnier than the rest of Oregon. Klamath Falls roofs get 31% more usable sunlight than the typical Oregon city we've measured — statewide averages will understate what you can expect here.
- Older imagery. Google's aerial capture of Klamath Falls dates from 2019. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight

Klamath Falls solar questions
How many solar panels do I need in Klamath Falls?
About 18 panels for an average home using 10,800 kWh a year. Klamath Falls roofs get 1,839 usable sun hours, so each 400W panel produces roughly 625 kWh annually. A typical Klamath Falls roof fits about 36 panels, so roof space is unlikely to be your limit.
Is solar worth it in Klamath Falls?
At 12.4¢/kWh and 1,839 sun hours, a typical system pays for itself in about 10.6 years and returns roughly $19,468 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 Klamath Falls?
A 7.2 kW system costs about $20,520 before incentives and $14,364 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.
