What a typical Santa Clarita solar system costs
A 16-panel system (6.4 kW) is about right for an average Santa Clarita home using 10,800 kWh a year. It would produce roughly 11,125 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,562 | $6,384 | $1,291 | 4.9 yrs |
| 12 panels | 4.8 kW | 8,344 | $9,576 | $1,464 | 6.5 yrs |
| 16 panels | 6.4 kW | 11,125 | $12,768 | $1,638 | 7.8 yrs |
| 20 panels | 8 kW | 13,906 | $15,960 | $1,811 | 8.8 yrs |
| 26 panels | 10.4 kW | 18,078 | $20,748 | $2,072 | 10 yrs |
How we worked this out for Santa Clarita
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Santa Clarita rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 2,045 sun hrs × 0.85 system losses |
695 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 695 kWh per panel |
16 panels |
| 3 | System size 16 panels × 400W |
6.40 kW |
| 4 | Annual production 6.40 kW × 2,045 hrs × 0.85 |
11,125 kWh/yr |
| 5 | Installed cost 6,400 W × $2.85 per watt, then −30% federal credit |
$12,768 |
| 6 | Annual saving 3,780 kWh used as generated × 31.2¢ + 7,345 kWh exported × 6.2¢ |
$1,638/yr |
| 7 | Payback $12,768 ÷ $1,638 per year |
7.8 years |
Step 6 is where most calculators quietly overstate things. Only 34% of what a system this size produces in Santa Clarita is used the moment it is generated; the other 7,345 kWh is exported and credited at 20% of retail under net billing. Valuing every kWh at the full 31.2¢ retail rate — which many calculators do — would show a payback of 3.7 years instead of the 7.8 we show. That 4.1-year difference is the single biggest reason our figures look worse than other sites' for Santa Clarita.
Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), $2.85/W installed, 10,800 kWh typical annual household use, 31.2¢/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 Santa Clarita gets 2,045 sun hours
That figure comes from Google's analysis of real rooftops across Santa Clarita — 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 Santa Clarita reaches about 2,113 hours, roughly 3% better than typical.

When Santa Clarita actually produces
Annual totals hide the thing that catches people out: 34% of Santa Clarita's yearly sunlight arrives in May–July, and just 15% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 105 | |
| Feb | 134 | |
| Mar | 169 | |
| Apr | 203 | |
| May | 226 | |
| Jun | 234 | |
| Jul | 230 | |
| Aug | 211 | |
| Sep | 181 | |
| Oct | 144 | |
| Nov | 112 | |
| Dec | 97 |
Output is unusually steady — only about 2.4× between Jun and Dec. Santa Clarita 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 Santa Clarita's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Santa Clarita compares to the other 788 cities
| Measure | Santa Clarita | Rank of 788 |
|---|---|---|
| Usable sunlight | 2,045 hrs | 12th |
| Sunlight lost to shade | 3% | 614th most |
| Median roof size | 116 m² | 667th largest |
| Electricity rate | 31.2¢ | 24th highest |
| Payback | 7.8 yrs | 74th fastest |
| Grid carbon | 429 kg/MWh | 675th dirtiest |
What actually stands out about Santa Clarita:
- The case here is financial, not environmental. Santa Clarita's grid is already clean at 429 kg CO₂ per MWh, so the carbon saving from solar is modest. Judge this one on payback.
- Sunnier than the rest of California. Santa Clarita roofs get 7% more usable sunlight than the typical California city we've measured — statewide averages will understate what you can expect here.
- Expensive electricity works in your favour. At 31.2¢/kWh, California is among the priciest places to buy power — which is exactly what makes generating your own pay back faster.
Cities with almost the same sunlight
These are the closest matches to Santa Clarita's 2,045 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 |

| Henderson, NV | 2,045 | 15.3¢ | 7.7 yrs |
| Tucson, AZ | 2,043 | 15.2¢ | 7.7 yrs |

Santa Clarita solar questions
How many solar panels do I need in Santa Clarita?
About 16 panels for an average home using 10,800 kWh a year. Santa Clarita roofs get 2,045 usable sun hours, so each 400W panel produces roughly 695 kWh annually. A typical Santa Clarita roof fits about 38 panels, so roof space is unlikely to be your limit.
Is solar worth it in Santa Clarita?
At 31.2¢/kWh and 2,045 sun hours, a typical system pays for itself in about 7.8 years and returns roughly $28,174 over a 25-year panel life. That is a solid return, and it improves further if electricity prices rise. Exports earn only 20% of retail, so using power as you generate it matters.
How much do solar panels cost in Santa Clarita?
A 6.4 kW system costs about $18,240 before incentives and $12,768 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.
