What a typical Sandy Springs solar system costs
A 24-panel system (9.6 kW) is about right for an average Sandy Springs home using 10,800 kWh a year. It would produce roughly 11,261 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,754 | $6,384 | $529 | 12.1 yrs |
| 12 panels | 4.8 kW | 5,630 | $9,576 | $794 | 12.1 yrs |
| 16 panels | 6.4 kW | 7,507 | $12,768 | $1,059 | 12.1 yrs |
| 20 panels | 8 kW | 9,384 | $15,960 | $1,323 | 12.1 yrs |
| 26 panels | 10.4 kW | 12,199 | $20,748 | $1,572 | 13.2 yrs |
How we worked this out for Sandy Springs
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Sandy Springs rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,380 sun hrs × 0.85 system losses |
469 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 469 kWh per panel |
24 panels |
| 3 | System size 24 panels × 400W |
9.60 kW |
| 4 | Annual production 9.60 kW × 1,380 hrs × 0.85 |
11,261 kWh/yr |
| 5 | Installed cost 9,600 W × $2.85 per watt, then −30% federal credit |
$19,152 |
| 6 | Annual saving 3,780 kWh used as generated × 14.1¢ + 7,481 kWh exported × 14.1¢ |
$1,539/yr |
| 7 | Payback $19,152 ÷ $1,539 per year |
12.4 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in Sandy Springs is used the moment it is generated; the other 7,481 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, 14.1¢/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 Sandy Springs gets 1,380 sun hours
That figure comes from Google's analysis of real rooftops across Sandy Springs — 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 Sandy Springs reaches about 1,680 hours, roughly 22% better than typical.

When Sandy Springs actually produces
Annual totals hide the thing that catches people out: 34% of Sandy Springs's yearly sunlight arrives in May–July, and just 16% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 72 | |
| Feb | 91 | |
| Mar | 114 | |
| Apr | 137 | |
| May | 152 | |
| Jun | 157 | |
| Jul | 154 | |
| Aug | 142 | |
| Sep | 122 | |
| Oct | 97 | |
| Nov | 76 | |
| Dec | 66 |
Output is unusually steady — only about 2.4× between Jun and Dec. Sandy Springs is close enough to the equator that seasonal variation is mild, which makes sizing a system considerably more predictable.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Sandy Springs's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Sandy Springs compares to the other 788 cities
| Measure | Sandy Springs | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,380 hrs | 570th |
| Sunlight lost to shade | 18% | 4th most |
| Median roof size | 266 m² | 180th largest |
| Electricity rate | 14.1¢ | 582nd highest |
| Payback | 12.4 yrs | 576th fastest |
| Grid carbon | 663 kg/MWh | 288th dirtiest |
What actually stands out about Sandy Springs:
- Shading is a real problem here. Sandy Springs loses 18% of its potential sunlight to trees, chimneys and neighbouring buildings — the 4th-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.
- Dimmer than the rest of Georgia. Sandy Springs roofs get 11% less usable sunlight than the typical Georgia city we've measured — statewide averages will overstate what you can expect here.

Sandy Springs solar questions
How many solar panels do I need in Sandy Springs?
About 24 panels for an average home using 10,800 kWh a year. Sandy Springs roofs get 1,380 usable sun hours, so each 400W panel produces roughly 469 kWh annually. A typical Sandy Springs roof fits about 89 panels, so roof space is unlikely to be your limit.
Is solar worth it in Sandy Springs?
At 14.1¢/kWh and 1,380 sun hours, a typical system pays for itself in about 12.4 years and returns roughly $19,324 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 Sandy Springs?
A 9.6 kW system costs about $27,360 before incentives and $19,152 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.
