Indiana solar leads

The solar resource at Indianapolis

Indianapolis is Indiana’s largest city in the Census Bureau’s July 1, 2025 estimates; the Census Bureau reports it as the balance of the consolidated city. The PVWatts calculator, first built by NREL and now operated by the National Laboratory of the Rockies, gives 4.62 kWh per square meter per day there (checked October 9, 2026).

The calculation used PVWatts version 8’s default system, a fixed open-rack array facing due south at a 20-degree tilt, at the city’s point in the Census gazetteer, with typical-year data from the National Solar Radiation Database. Northern Indiana, a different roof angle or nearby trees would each produce another figure, so it is useful for comparing places, not for predicting one house.

From net metering to excess distributed generation in Indiana

Indiana’s rules for customer solar are in chapter 8-1-40 of the Indiana Code, Distributed Generation, added in 2017 (2026 Indiana Code, checked October 9, 2026). Section 11 says that after June 30, 2022, an electricity supplierSupplierAny company that provides leads to a buyer, whether it generates them itself or brokers them from publishers. Glossary may not make a net metering tariff available, and the terms of tariffs offered before July 1, 2022 expire except for the customers sections 13 and 14 protect. The chapter applies to public utilities that sell retail electricity; under section 4 it does not cover municipally owned utilities or cooperatives organized under IC 8-1-13.

Those protections depend on when a system went in. A customer already on a net metering tariff on December 31, 2017 keeps it until the system is removed or replaced, or until July 1, 2047. A customer that installed after that date and before its supplier’s tariff closed keeps it until removal, replacement or July 1, 2032. In both cases a later owner of the premises may choose to stay on the tariff for the same period.

New customers are compensated for excess distributed generation instead: the difference between the electricity the supplier delivers to the customer and the electricity the customer sends back. Section 17 has the Indiana Utility Regulatory Commission approve a rate equal to the supplier’s average marginal price of electricity in the most recent calendar year multiplied by 1.25, and section 18 has the supplier credit the customer’s monthly bill, carrying any excess credit forward as long as the customer is served at the premises. This page states no credit value.

Indiana’s detached housing and owners

Indiana is a state of houses. In the Census Bureau’s table B25024 for 2020-2024, 2,162,475 of the 2,976,568 housing units are single-family detached homes, 72.6%, and only two states have a higher share. Table B25032 shows 1,753,511 detached houses among 1,916,243 owner-occupied homes, or 91.5%.

Housing age and values are covered on Indiana window replacement leads, and home heating on Indiana HVAC leads.

Reading Indiana’s numbers as a solar buyer

The statute and the housing data point in a few directions for anyone planning Indiana solar coverage:

• Installers explain the credit, not net metering. Under IC 8-1-40 (2026 Indiana Code), new customers of public utilities receive the excess distributed generation credit, so the first call covers how exports are credited.
• Almost every owner home is a house. With 91.5% of owner-occupied homes detached in the 2020-2024 ACS, housing type narrows an Indiana campaign less than it does in most states.
• The installed base grows slowly. Small-scale capacity rose 6.5% between July 2025 and July 2026 in the EIA estimates, so most Indiana roofs still have no system.

These points come from statutes, housing counts and installed capacity. They do not measure the number of solar leads in Indiana or any part of it.
