What a typical Pearland solar system costs
A 20-panel system (8 kW) is about right for an average Pearland home using 10,800 kWh a year. It would produce roughly 11,240 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,496 | $6,384 | $679 | 9.4 yrs |
| 12 panels | 4.8 kW | 6,744 | $9,576 | $1,018 | 9.4 yrs |
| 16 panels | 6.4 kW | 8,992 | $12,768 | $1,358 | 9.4 yrs |
| 20 panels | 8 kW | 11,240 | $15,960 | $1,647 | 9.7 yrs |
| 26 panels | 10.4 kW | 14,613 | $20,748 | $1,775 | 11.7 yrs |
How we worked this out for Pearland
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Pearland rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,653 sun hrs × 0.85 system losses |
562 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 562 kWh per panel |
20 panels |
| 3 | System size 20 panels × 400W |
8.00 kW |
| 4 | Annual production 8.00 kW × 1,653 hrs × 0.85 |
11,240 kWh/yr |
| 5 | Installed cost 8,000 W × $2.85 per watt, then −30% federal credit |
$15,960 |
| 6 | Annual saving 3,780 kWh used as generated × 15.1¢ + 7,460 kWh exported × 15.1¢ |
$1,647/yr |
| 7 | Payback $15,960 ÷ $1,647 per year |
9.7 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in Pearland is used the moment it is generated; the other 7,460 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 — 9.4 years against the 9.7 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 Pearland gets 1,653 sun hours
That figure comes from Google's analysis of real rooftops across Pearland — 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 Pearland reaches about 1,717 hours, roughly 4% better than typical.

When Pearland actually produces
Annual totals hide the thing that catches people out: 32% of Pearland's yearly sunlight arrives in May–July, and just 17% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 94 | |
| Feb | 114 | |
| Mar | 138 | |
| Apr | 161 | |
| May | 174 | |
| Jun | 179 | |
| Jul | 176 | |
| Aug | 165 | |
| Sep | 146 | |
| Oct | 121 | |
| Nov | 98 | |
| Dec | 88 |
Output is unusually steady — only about 2.0× between Jun and Dec. Pearland 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 Pearland's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Pearland compares to the other 788 cities
| Measure | Pearland | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,653 hrs | 248th |
| Sunlight lost to shade | 4% | 553rd most |
| Median roof size | 78 m² | 741st largest |
| Electricity rate | 15.1¢ | 498th highest |
| Payback | 9.7 yrs | 322nd fastest |
| Grid carbon | 639 kg/MWh | 405th dirtiest |
What actually stands out about Pearland:
- Roof space is the binding constraint. A typical Pearland roof fits about 29 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 Pearland roof is 78 m², smaller than 94% of cities measured — worth checking your own footprint before assuming a standard system fits.
- Dimmer than the rest of Texas. Pearland roofs get 6% less usable sunlight than the typical Texas city we've measured — statewide averages will overstate what you can expect here.
Cities with almost the same sunlight
These are the closest matches to Pearland's 1,653 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.

Pearland solar questions
How many solar panels do I need in Pearland?
About 20 panels for an average home using 10,800 kWh a year. Pearland roofs get 1,653 usable sun hours, so each 400W panel produces roughly 562 kWh annually. A typical Pearland roof fits about 29 panels, so check your usable roof area before assuming that many will fit.
Is solar worth it in Pearland?
At 15.1¢/kWh and 1,653 sun hours, a typical system pays for itself in about 9.7 years and returns roughly $25,226 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 Pearland?
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.
