Solar panels in Garden City, KS
Roofs in Garden City get about 1,847 hours of usable sunlight a year — more than 84% 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 Garden City → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Garden City solar system costs
A 18-panel system (7.2 kW) is about right for an average Garden City home using 10,800 kWh a year. It would produce roughly 11,304 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,024 | $6,384 | $708 | 9 yrs |
| 12 panels | 4.8 kW | 7,536 | $9,576 | $1,063 | 9 yrs |
| 16 panels | 6.4 kW | 10,048 | $12,768 | $1,417 | 9 yrs |
| 20 panels | 8 kW | 12,560 | $15,960 | $1,585 | 10.1 yrs |
| 26 panels | 10.4 kW | 16,327 | $20,748 | $1,718 | 12.1 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 Garden City gets 1,847 sun hours
That figure comes from Google's analysis of real rooftops across Garden City — 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 Garden City reaches about 1,930 hours, roughly 4% better than typical.

When Garden City actually produces
Annual totals hide the thing that catches people out: 35% of Garden City's yearly sunlight arrives in May–July, and just 14% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 87 | |
| Feb | 115 | |
| Mar | 151 | |
| Apr | 187 | |
| May | 212 | |
| Jun | 221 | |
| Jul | 216 | |
| Aug | 196 | |
| Sep | 163 | |
| Oct | 125 | |
| Nov | 94 | |
| Dec | 80 |
Garden City produces about 2.8× 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 Garden City's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Garden City compares to the other 673 cities
| Measure | Garden City | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,847 hrs | 105th |
| Sunlight lost to shade | 4% | 430th most |
| Median roof size | 273 m² | 167th largest |
| Electricity rate | 14.1¢ | 482nd highest |
| Payback | 9.3 yrs | 285th fastest |
| Grid carbon | 909 kg/MWh | 14th dirtiest |
What actually stands out about Garden City:
- Plenty of roof to work with. Typical roofs here fit around 97 panels — roughly 5× what an average home needs. Roof size will not be what limits your system in Garden City.
- Every kWh counts more here. The grid serving Garden City emits 909 kg CO₂ per MWh, among the highest of the 673 cities measured — so the same panels displace more emissions than they would elsewhere.
- Sunnier than the rest of Kansas. Garden City roofs get 12% more usable sunlight than the typical Kansas city we've measured — statewide averages will understate what you can expect here.
- Older imagery. Google's aerial capture of Garden City dates from 2017. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Garden City's 1,847 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 |
|---|---|---|---|
| West Covina, CA | 1,848 | 31.2¢ | 8.7 yrs |
| Salinas, CA | 1,850 | 31.2¢ | 8.7 yrs |

Garden City solar questions
How many solar panels do I need in Garden City?
About 18 panels for an average home using 10,800 kWh a year. Garden City roofs get 1,847 usable sun hours, so each 400W panel produces roughly 628 kWh annually. A typical Garden City roof fits about 97 panels, so roof space is unlikely to be your limit.
Is solar worth it in Garden City?
At 14.1¢/kWh and 1,847 sun hours, a typical system pays for itself in about 9.3 years and returns roughly $24,150 over a 25-year panel life. That is a solid return, and it improves further if electricity prices rise. Exported power earns full retail credit here.
How much do solar panels cost in Garden City?
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.
