What the planet gets
Net metering credits exported power against what you draw from the grid. Rates vary by state, California's NEM 3.0 pays much less for exports than 1:1 states.

17.5 years
US average: 10.6 years
Slower than the US average on a $150 bill
Solar cost & savings by system size in Indiana
Computed with Indiana's rate (16¢/kWh), sun (~3.9 kWh/kW/day), and its reduced export credit, at the 2026 national benchmark of ~$2.75/W with no federal credit.
| System size | Installed cost | Generation/mo | Annual savings | Payback |
|---|---|---|---|---|
| 4kW | ~$11,000 | ~468 kWh | ~$629 | ~17.5 yrs |
| 6kW | ~$16,500 | ~702 kWh | ~$943 | ~17.5 yrs |
| 8kW | ~$22,000 | ~936 kWh | ~$1,258 | ~17.5 yrs |
| 10kW | ~$27,500 | ~1,170 kWh | ~$1,572 | ~17.5 yrs |
Savings assume a home large enough to use this output. Figures last reviewed July 2026,size a system from your actual bill instead.
How exports are paid in Indiana
Net metering has largely closed; new systems use 'excess distributed generation' credits below retail.
Because Indiana pays less than the full retail rate for exported power, the numbers reward using more of your own solar, running big loads in daylight, or adding a battery to store the surplus instead of exporting it cheaply.
Policies change often, always confirm current rules with your utility or at DSIREbefore deciding.
Indiana solar FAQs
Is solar worth it in Indiana in 2026?
For a typical $150/month bill, we estimate a Indiana system pays for itself in about 17.5 years, with no federal tax credit assumed (the residential credit expired at the end of 2025). At 16¢/kWh with net billing (reduced export rate), the case is workable but depends on your roof, usage pattern, and quotes.
How much does a solar system cost in Indiana?
At 2026 benchmark prices (~$2.75/W), a 6kW system runs about $16,500 installed, generating roughly 702 kWh a month in Indiana's sun. Local quotes vary 20-40% between installers, so always collect several.
What is the net metering policy in Indiana?
Net metering has largely closed; new systems use 'excess distributed generation' credits below retail.
Does Indiana have a state solar incentive?
Self-consumption is the main value now that 1:1 has sunset. Since the federal residential credit ended in 2025, state and utility incentives are the main upfront help available.
How many solar panels do I need in Indiana?
A 8 kW system suits a typical $150/month bill in Indiana, that's roughly 19 modern 425W panels needing about 520 sq ft of unshaded roof. Enter your own bill in the calculator above for a precise size.
