A worked example: 8 kW in Louisiana
An 8 kW system — about 19 × 425-watt panels — at Louisiana's assumed installed cost of $2.35–$3.10 per watt runs roughly $18,800–$24,800 before incentives. At about 1,380 kWh of production per installed kW, it would generate around 11,040 kWh per year. Valuing self-consumed electricity at the assumed $0.12/kWh retail rate and exports conservatively, first-year savings land near $1,092 — a simple payback of roughly 17–23 years.
There is no federal tax credit in that math: the Section 25D residential credit ended for systems installed after December 31, 2025. State or utility incentives, where they exist, would shorten payback from here.
Net metering in Louisiana
Louisiana ended retail net metering for new customers; exports are credited near avoided cost. Self-consumption, not exports, drives savings for new systems.
Louisiana solar incentives
Louisiana’s once-generous state solar credit ended years ago and has not returned. No significant statewide incentive currently exists.
What changes a Louisiana solar quote?
Equipment, roof condition, electrical upgrades, permitting, labor, system size, batteries and financing can all change the installed price. Savings also depend on the specific utility rate, how much solar electricity the home uses directly, and what the utility pays for exports.
Frequently asked questions
How much do solar panels cost in Louisiana?
Using an assumed installed cost of $2.35–$3.10 per watt, a typical 8 kW home system in Louisiana costs roughly $18,800–$24,800 before incentives. Smaller and larger systems scale roughly with size, though small systems cost more per watt.
Is solar worth it in Louisiana?
With Louisiana electricity around $0.12/kWh and production around 1,380 kWh per installed kW per year, an 8 kW system could save roughly $1,092 in year one, for a simple payback of about 17–23 years with no federal credit. Whether that is "worth it" depends on your rate plan, export compensation, roof, and how long you plan to stay in the home.
Does Louisiana have net metering?
Louisiana ended retail net metering for new customers; exports are credited near avoided cost. Self-consumption, not exports, drives savings for new systems.
What solar incentives does Louisiana offer in 2026?
Louisiana’s once-generous state solar credit ended years ago and has not returned. No significant statewide incentive currently exists. Note that the federal Section 25D residential credit ended for systems installed after December 31, 2025, so state, local and utility programs are now the main incentives for purchased systems.
Is there still a federal solar tax credit in Louisiana?
No — the 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Leased or PPA systems may still benefit indirectly because the system owner can claim the commercial 48E credit through 2027.
