Solar panels in Lubbock, TX
Roofs in Lubbock get about 2,006 hours of usable sunlight a year — more than 97% 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.

What a typical Lubbock solar system costs
A 16-panel system (6.4 kW) is about right for an average Lubbock home using 10,800 kWh a year. It would produce roughly 10,913 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,456 | $6,384 | $824 | 7.7 yrs |
| 12 panels | 4.8 kW | 8,184 | $9,576 | $1,236 | 7.7 yrs |
| 16 panels | 6.4 kW | 10,913 | $12,768 | $1,635 | 7.8 yrs |
| 20 panels | 8 kW | 13,641 | $15,960 | $1,738 | 9.2 yrs |
| 26 panels | 10.4 kW | 17,733 | $20,748 | $1,893 | 11 yrs |
How we worked this out for Lubbock
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Lubbock rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 2,006 sun hrs × 0.85 system losses |
682 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 682 kWh per panel |
16 panels |
| 3 | System size 16 panels × 400W |
6.40 kW |
| 4 | Annual production 6.40 kW × 2,006 hrs × 0.85 |
10,913 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 × 15.1¢ + 7,133 kWh exported × 15.1¢ |
$1,635/yr |
| 7 | Payback $12,768 ÷ $1,635 per year |
7.8 years |
Step 6 matters more than it looks. Only 35% of what a system this size produces in Lubbock is used the moment it is generated; the other 7,133 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 — 7.7 years against the 7.8 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, 15.1¢/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 Lubbock gets 2,006 sun hours
That figure comes from Google's analysis of real rooftops across Lubbock — 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 Lubbock reaches about 2,068 hours, roughly 3% better than typical.

When Lubbock actually produces
Annual totals hide the thing that catches people out: 33% of Lubbock's yearly sunlight arrives in May–July, and just 16% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 105 | |
| Feb | 132 | |
| Mar | 166 | |
| Apr | 198 | |
| May | 220 | |
| Jun | 228 | |
| Jul | 223 | |
| Aug | 206 | |
| Sep | 177 | |
| Oct | 142 | |
| Nov | 111 | |
| Dec | 97 |
Output is unusually steady — only about 2.3× between Jun and Dec. Lubbock 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 Lubbock's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Lubbock compares to the other 788 cities
| Measure | Lubbock | Rank of 788 |
|---|---|---|
| Usable sunlight | 2,006 hrs | 25th |
| Sunlight lost to shade | 3% | 634th most |
| Median roof size | 304 m² | 117th largest |
| Electricity rate | 15.1¢ | 474th highest |
| Payback | 7.8 yrs | 73rd fastest |
| Grid carbon | 758 kg/MWh | 191st dirtiest |
What actually stands out about Lubbock:
- Plenty of roof to work with. Typical roofs here fit around 92 panels — roughly 5× what an average home needs. Roof size will not be what limits your system in Lubbock.
- Sunnier than the rest of Texas. Lubbock roofs get 14% more usable sunlight than the typical Texas city we've measured — statewide averages will understate what you can expect here.
- Older imagery. Google's aerial capture of Lubbock dates from 2018. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Lubbock's 2,006 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 |
|---|---|---|---|
| Thousand Oaks, CA | 2,007 | 31.2¢ | 7.9 yrs |
| Farmington, NM | 2,008 | 14.8¢ | 8 yrs |
| Corona, CA | 2,002 | 31.2¢ | 7.9 yrs |

Lubbock solar questions
How many solar panels do I need in Lubbock?
About 16 panels for an average home using 10,800 kWh a year. Lubbock roofs get 2,006 usable sun hours, so each 400W panel produces roughly 682 kWh annually. A typical Lubbock roof fits about 92 panels, so roof space is unlikely to be your limit.
Is solar worth it in Lubbock?
At 15.1¢/kWh and 2,006 sun hours, a typical system pays for itself in about 7.8 years and returns roughly $28,108 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 Lubbock?
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.
