Solar panels in Victoria, TX
Roofs in Victoria get about 1,670 hours of usable sunlight a year — more than 65% 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 Victoria → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Victoria solar system costs
A 20-panel system (8 kW) is about right for an average Victoria home using 10,800 kWh a year. It would produce roughly 11,356 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,542 | $6,384 | $686 | 9.3 yrs |
| 12 panels | 4.8 kW | 6,814 | $9,576 | $1,029 | 9.3 yrs |
| 16 panels | 6.4 kW | 9,085 | $12,768 | $1,372 | 9.3 yrs |
| 20 panels | 8 kW | 11,356 | $15,960 | $1,652 | 9.7 yrs |
| 26 panels | 10.4 kW | 14,763 | $20,748 | $1,780 | 11.7 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 Victoria gets 1,670 sun hours
That figure comes from Google's analysis of real rooftops across Victoria — 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 Victoria reaches about 1,730 hours, roughly 4% better than typical.

When Victoria actually produces
Annual totals hide the thing that catches people out: 32% of Victoria's yearly sunlight arrives in May–July, and just 17% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 96 | |
| Feb | 116 | |
| Mar | 140 | |
| Apr | 162 | |
| May | 175 | |
| Jun | 179 | |
| Jul | 176 | |
| Aug | 166 | |
| Sep | 147 | |
| Oct | 123 | |
| Nov | 100 | |
| Dec | 90 |
Output is unusually steady — only about 2.0× between Jun and Dec. Victoria 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 Victoria's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Victoria compares to the other 673 cities
| Measure | Victoria | Rank of 673 |
|---|---|---|
| Usable sunlight | 1,670 hrs | 236th |
| Sunlight lost to shade | 3% | 502nd most |
| Median roof size | 77 m² | 654th largest |
| Electricity rate | 15.1¢ | 388th highest |
| Payback | 9.7 yrs | 325th fastest |
| Grid carbon | 639 kg/MWh | 409th dirtiest |
What actually stands out about Victoria:
- Roof space is the binding constraint. A typical Victoria roof fits about 24 panels and a typical home needs 20 — so there is little room to oversize. If you add an EV or heat pump later, plan the array for it now.
- Small roofs. The median Victoria roof is 77 m², smaller than 97% of cities measured — worth checking your own footprint before assuming a standard system fits.
- Older imagery. Google's aerial capture of Victoria dates from 2013. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Victoria's 1,670 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 |
|---|---|---|---|
| Charleston, SC | 1,670 | 14.2¢ | 10.3 yrs |
| Lafayette, LA | 1,672 | 12.1¢ | 11.6 yrs |
| Lee's Summit, MO | 1,668 | 12.2¢ | 12 yrs |
| Florence, SC | 1,672 | 14.2¢ | 9.9 yrs |

Victoria solar questions
How many solar panels do I need in Victoria?
About 20 panels for an average home using 10,800 kWh a year. Victoria roofs get 1,670 usable sun hours, so each 400W panel produces roughly 568 kWh annually. A typical Victoria roof fits about 24 panels, so check your usable roof area before assuming that many will fit.
Is solar worth it in Victoria?
At 15.1¢/kWh and 1,670 sun hours, a typical system pays for itself in about 9.7 years and returns roughly $25,335 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 Victoria?
A 8 kW system costs about $22,800 before incentives and $15,960 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.
