Solar panels in St. Cloud, MN
Roofs in St. Cloud get about 1,426 hours of usable sunlight a year — less than 63% 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 St. Cloud → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical St. Cloud solar system costs
A 23-panel system (9.2 kW) is about right for an average St. Cloud home using 10,800 kWh a year. It would produce roughly 11,151 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,879 | $6,384 | $574 | 11.1 yrs |
| 12 panels | 4.8 kW | 5,818 | $9,576 | $861 | 11.1 yrs |
| 16 panels | 6.4 kW | 7,757 | $12,768 | $1,148 | 11.1 yrs |
| 20 panels | 8 kW | 9,697 | $15,960 | $1,435 | 11.1 yrs |
| 26 panels | 10.4 kW | 12,606 | $20,748 | $1,665 | 12.5 yrs |
How we worked this out for St. Cloud
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from St. Cloud rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,426 sun hrs × 0.85 system losses |
485 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 485 kWh per panel |
23 panels |
| 3 | System size 23 panels × 400W |
9.20 kW |
| 4 | Annual production 9.20 kW × 1,426 hrs × 0.85 |
11,151 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 × 14.8¢ + 7,371 kWh exported × 14.8¢ |
$1,611/yr |
| 7 | Payback $18,354 ÷ $1,611 per year |
11.4 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in St. Cloud is used the moment it is generated; the other 7,371 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 — 11.1 years against the 11.4 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, 14.8¢/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 St. Cloud gets 1,426 sun hours
That figure comes from Google's analysis of real rooftops across St. Cloud — 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 St. Cloud reaches about 1,460 hours, roughly 2% better than typical.

When St. Cloud actually produces
Annual totals hide the thing that catches people out: 39% of St. Cloud's yearly sunlight arrives in May–July, and just 11% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 54 | |
| Feb | 79 | |
| Mar | 112 | |
| Apr | 150 | |
| May | 178 | |
| Jun | 190 | |
| Jul | 183 | |
| Aug | 160 | |
| Sep | 126 | |
| Oct | 88 | |
| Nov | 59 | |
| Dec | 47 |
That is a severe seasonal swing — St. Cloud produces roughly 4.0× 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 St. Cloud's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How St. Cloud compares to the other 788 cities
| Measure | St. Cloud | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,426 hrs | 498th |
| Sunlight lost to shade | 2% | 694th most |
| Median roof size | 499 m² | 6th largest |
| Electricity rate | 14.8¢ | 534th highest |
| Payback | 11.4 yrs | 476th fastest |
| Grid carbon | 832 kg/MWh | 101st dirtiest |
What actually stands out about St. Cloud:
- Unusually open roofs. Only 2% of available sunlight is lost to obstruction in St. Cloud — better than all but 94 of the 788 cities measured. Most roofs here get close to their theoretical maximum.
- Plenty of roof to work with. Typical roofs here fit around 190 panels — roughly 8× what an average home needs. Roof size will not be what limits your system in St. Cloud.
- Large roofs. At a median of 499 m², St. Cloud has the 6th-largest typical roof footprint we've measured.
- Every kWh counts more here. The grid serving St. Cloud emits 832 kg CO₂ per MWh, among the highest of the 788 cities measured — so the same panels displace more emissions than they would elsewhere.
Cities with almost the same sunlight
These are the closest matches to St. Cloud's 1,426 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 |
|---|---|---|---|
| Marquette, MI | 1,426 | 19.1¢ | 8.8 yrs |
| Cleveland, OH | 1,425 | 15.2¢ | 11.1 yrs |

St. Cloud solar questions
How many solar panels do I need in St. Cloud?
About 23 panels for an average home using 10,800 kWh a year. St. Cloud roofs get 1,426 usable sun hours, so each 400W panel produces roughly 485 kWh annually. A typical St. Cloud roof fits about 190 panels, so roof space is unlikely to be your limit.
Is solar worth it in St. Cloud?
At 14.8¢/kWh and 1,426 sun hours, a typical system pays for itself in about 11.4 years and returns roughly $21,931 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 St. Cloud?
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.
