In 2026, the most meaningful incentives for solar and energy-efficient home upgrades in Pennsylvania, Ohio, Kentucky, Tennessee, and West Virginia fall into a few consistent categories:

State-run “Home Energy Rebates” (cash rebates for electrification and whole-home efficiency)
Utility rebates (HVAC, insulation, appliances, audits)
Net metering / buyback credits (how you get paid for excess solar generation)
Performance incentives (SRECs/RECs) (primarily PA, limited OH)
Income-qualified assistance + financing (weatherization, bill help, low-interest loans)

A major 2026 change: the federal homeowner tax credits for solar (25D) and efficiency upgrades (25C) are not available for expenditures/placements after December 31, 2025. That makes rebates, bill credits, SRECs (where available), and financing the primary levers in these five states.

Most relevant incentive categories by state

Pennsylvania

State “Home Energy Rebates” (cash rebates)

Penn Energy Savers (DEP): PA’s umbrella program for the two DOE rebate tracks (efficiency retrofits + electrification/appliances). As of January 2026, PA indicated it was awaiting final DOE approval to launch the HEAR program, with HER opening thereafter.
Utility efficiency rebates

Many PA utilities run appliance/HVAC/insulation rebates (often ENERGY STAR–aligned). Example: Energy Save PA (FirstEnergy territories) offers appliance/HVAC rebates.
Solar bill credits (net metering)

PA requires net metering for qualifying customer-generators under 52 Pa. Code Chapter 75
Solar performance income (SRECs/SAECs)

PA has a well-known solar credit market: one credit per 1 MWh generated; credits can typically be sold via aggregators.
Low-interest financing

PA's HEELP (PHFA) offers low-interest loans for certain energy-efficiency repairs (helpful when rebates don’t cover the full project).

Ohio

Utility + state/local efficiency programs

Ohio has multiple pathways that vary by utility and locality; also consider state/local financing programs (below).
Solar bill credits (net metering)

Ohio utilities must offer net metering via a standard tariff/contract under ORC 4928.67.
Property tax treatment (solar)

Ohio provides a real property tax exemption for many smaller energy facilities (commonly applicable to residential-scale solar): ORC 5709.53 includes exemption language for facilities ≤ 250 kW.
Financing incentive (home efficiency upgrades)

ECO-Link (Ohio Treasury linked-deposit): offers an interest rate reduction on qualifying bank loans for homeowners making energy-efficiency improvements.
Income-qualified bill help + weatherization

Ohio administers federally funded HEAP and the Home Weatherization Assistance Program for qualifying households.

Kentucky

State “Home Energy Rebates” (cash rebates)

Kentucky's rebate hub is energyrebates.ky.gov, with the program administered by the KY Energy & Environment Cabinet Office of Energy Policy.
Utility efficiency rebates

Many KY utilities offer rebates for efficiency upgrades; for example, LG&E/KU promotes efficiency and rebate programs.
Solar bill credits (net metering)

Kentucky statute defines net metering and eligible customer-generators in KRS 278.465 (with compensation handled through applicable tariffs/rules).
Sales/property tax exemptions (solar)

Kentucky's Energy & Environment Cabinet notes KY does not offer a sales tax exemption or property tax exemption for residential solar arrays.

Tennessee

State “Home Energy Rebates” (cash rebates)

Tennessee's State Energy Office describes both rebate tracks and example rebate ranges (including $2,000–$8,000 for some single-family retrofits, and higher caps for multifamily depending on rules).
Utility efficiency rebates

In much of TN, the biggest efficiency incentives run through TVA EnergyRight (rebates for home energy upgrades; business incentives also exist).
Solar compensation

Tennessee does not have a single statewide net metering policy in the way many states do; in TVA territory, customer compensation is commonly structured through TVA programs.

TVA Dispersed Power Production (DPP): allows eligible customers to sell all or excess generation to TVA at TVA’s monthly avoided cost.
Financing (primarily for entities)

Tennessee’s Energy Efficiency & Renewable Energy Loan Program supports qualifying entities (often public/organizational projects rather than standard homeowner loans).

West Virginia

State “Home Energy Rebates” (cash rebates)

West Virginia's Office of Energy site (EnergyWV) outlines the two rebate tracks (whole-home efficiency and electrification/appliances) and publishes eligibility guidance (including homeowners and renters with landlord authorization).
Solar bill credits (net metering framework)

West Virginia's administrative rules and utility riders govern interconnection/net metering; West Virginia rule documentation includes customer-generator requirements/fees.
Income-qualified weatherization

West Virginia's Weatherization Assistance Program is delivered through state/community action networks for eligible households.

Special note for rural businesses and farms (all five states)

If your page targets rural audiences (common in PA/OH/KY/TN/WV), the most relevant non-residential bucket is often USDA:

USDA REAP provides grants and guaranteed loans for ag producers and rural small businesses for renewable energy systems and efficiency improvements.
NRCS also runs the EQIP On-Farm Energy Initiative for on-farm efficiency improvements. (Program rules and funding windows can change; always verify current notices directly with USDA/NRCS.)
