Solar panels in Medford, OR
Roofs in Medford get about 1,562 hours of usable sunlight a year — more than 59% 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 Medford → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Medford solar system costs
A 21-panel system (8.4 kW) is about right for an average Medford home using 10,800 kWh a year. It would produce roughly 11,153 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,249 | $6,384 | $527 | 12.1 yrs |
| 12 panels | 4.8 kW | 6,373 | $9,576 | $790 | 12.1 yrs |
| 16 panels | 6.4 kW | 8,497 | $12,768 | $1,054 | 12.1 yrs |
| 20 panels | 8 kW | 10,622 | $15,960 | $1,317 | 12.1 yrs |
| 26 panels | 10.4 kW | 13,808 | $20,748 | $1,432 | 14.5 yrs |
How we worked this out for Medford
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Medford rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,562 sun hrs × 0.85 system losses |
531 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 531 kWh per panel |
21 panels |
| 3 | System size 21 panels × 400W |
8.40 kW |
| 4 | Annual production 8.40 kW × 1,562 hrs × 0.85 |
11,153 kWh/yr |
| 5 | Installed cost 8,400 W × $2.85 per watt, then −30% federal credit |
$16,758 |
| 6 | Annual saving 3,780 kWh used as generated × 12.4¢ + 7,373 kWh exported × 12.4¢ |
$1,350/yr |
| 7 | Payback $16,758 ÷ $1,350 per year |
12.4 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in Medford is used the moment it is generated; the other 7,373 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 — 12.1 years against the 12.4 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 Medford gets 1,562 sun hours
That figure comes from Google's analysis of real rooftops across Medford — 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 Medford reaches about 1,692 hours, roughly 8% better than typical.

When Medford actually produces
Annual totals hide the thing that catches people out: 37% of Medford's yearly sunlight arrives in May–July, and just 13% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 65 | |
| Feb | 91 | |
| Mar | 125 | |
| Apr | 161 | |
| May | 188 | |
| Jun | 198 | |
| Jul | 193 | |
| Aug | 171 | |
| Sep | 138 | |
| Oct | 101 | |
| Nov | 71 | |
| Dec | 59 |
Medford 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 Medford's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

What actually stands out about Medford:
- Sunnier than the rest of Oregon. Medford roofs get 11% more usable sunlight than the typical Oregon city we've measured — statewide averages will understate what you can expect here.
Cities with almost the same sunlight
These are the closest matches to Medford's 1,562 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.

Medford solar questions
How many solar panels do I need in Medford?
About 21 panels for an average home using 10,800 kWh a year. Medford roofs get 1,562 usable sun hours, so each 400W panel produces roughly 531 kWh annually. A typical Medford roof fits about 53 panels, so roof space is unlikely to be your limit.
Is solar worth it in Medford?
At 12.4¢/kWh and 1,562 sun hours, a typical system pays for itself in about 12.4 years and returns roughly $16,995 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 Medford?
A 8.4 kW system costs about $23,940 before incentives and $16,758 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.
