Solar panels in Shreveport, LA
Roofs in Shreveport get about 1,600 hours of usable sunlight a year — more than 64% 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 Shreveport solar system costs
A 20-panel system (8 kW) is about right for an average Shreveport home using 10,800 kWh a year. It would produce roughly 10,880 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,352 | $6,384 | $527 | 12.1 yrs |
| 12 panels | 4.8 kW | 6,528 | $9,576 | $790 | 12.1 yrs |
| 16 panels | 6.4 kW | 8,704 | $12,768 | $1,053 | 12.1 yrs |
| 20 panels | 8 kW | 10,880 | $15,960 | $1,309 | 12.2 yrs |
| 26 panels | 10.4 kW | 14,144 | $20,748 | $1,408 | 14.7 yrs |
How we worked this out for Shreveport
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Shreveport rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,600 sun hrs × 0.85 system losses |
544 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 544 kWh per panel |
20 panels |
| 3 | System size 20 panels × 400W |
8.00 kW |
| 4 | Annual production 8.00 kW × 1,600 hrs × 0.85 |
10,880 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 × 12.1¢ + 7,100 kWh exported × 12.1¢ |
$1,309/yr |
| 7 | Payback $15,960 ÷ $1,309 per year |
12.2 years |
Step 6 matters more than it looks. Only 35% of what a system this size produces in Shreveport is used the moment it is generated; the other 7,100 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 12.2 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, 12.1¢/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 Shreveport gets 1,600 sun hours
That figure comes from Google's analysis of real rooftops across Shreveport — 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 Shreveport reaches about 1,698 hours, roughly 6% better than typical.

When Shreveport actually produces
Annual totals hide the thing that catches people out: 33% of Shreveport's yearly sunlight arrives in May–July, and just 16% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 86 | |
| Feb | 107 | |
| Mar | 133 | |
| Apr | 158 | |
| May | 173 | |
| Jun | 179 | |
| Jul | 176 | |
| Aug | 163 | |
| Sep | 141 | |
| Oct | 114 | |
| Nov | 90 | |
| Dec | 80 |
Output is unusually steady — only about 2.3× between Jun and Dec. Shreveport 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 Shreveport's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

Shreveport solar questions
How many solar panels do I need in Shreveport?
About 20 panels for an average home using 10,800 kWh a year. Shreveport roofs get 1,600 usable sun hours, so each 400W panel produces roughly 544 kWh annually. A typical Shreveport roof fits about 59 panels, so roof space is unlikely to be your limit.
Is solar worth it in Shreveport?
At 12.1¢/kWh and 1,600 sun hours, a typical system pays for itself in about 12.2 years and returns roughly $16,771 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 Shreveport?
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.
