West Virginia's SolarDNA Market Score: 38 out of 100.
West Virginia scores 38 out of 100 on SolarDNA's Market Score, a 0-to-100 scale benchmarked against every other state market. That is higher than 47% of U.S. states. Grade C (Good).
The score combines 5 subscores, each computed from observed market data:
- Velocity (75): trailing-12-month growth in solar added versus the prior twelve months, so accelerating markets score higher.
- Cost (50): median installed $/W relative to the national median (a cheaper market scores higher).
- Incentives (30): net-metering coverage, RECs a new system can earn, state tax credit, rebate program and tax exemptions (components listed below).
- Resource (13): annual solar irradiance, so the same system produces more where this score is high.
- Depth (8): proven demand: how many systems are already installed, with a bonus for markets that show adoption without being saturated.
Federal: Federal residential credit (25D) ended for systems placed in service after Dec 31, 2025. Third-party-owned systems can still use the commercial credit (48E) through 2027 under construction-start rules.

How SolarDNA defines these metrics
Solar systems
Solar systems is the market-size figure: the systems utilities report on their lines, plus an estimate (sized from reported capacity) for systems outside net metering. It is current for every state.
How SolarDNA calculates solar systems →Tracked installations
Tracked installations are the individual residential, commercial and utility-scale systems SolarDNA holds a record for. SolarDNA de-duplicates the same system across records. Pricing, installers, equipment and every zip-level figure come from these records.
How SolarDNA calculates tracked installations →Median installed cost
Median installed cost is the middle price per watt (DC) that homeowners paid for a residential system in the trailing twelve months, before incentives. Quartiles show the spread.
How SolarDNA calculates median installed cost →Adoption rate
Adoption rate is the share of owner-occupied homes with a residential solar system. It measures how saturated a market is, not how fast it is growing.
How SolarDNA calculates adoption rate →12-month growth
For a state, growth compares the residential solar capacity added in the trailing twelve months with the twelve months before, from utility-reported totals with one-off reporting corrections smoothed out. For cities and zip codes it compares tracked installations.
How SolarDNA calculates 12-month growth →Battery share
Battery share is the portion of a state's solar customers whose system includes a battery, as reported by utilities.
How SolarDNA calculates battery share →Permits
Permits count the solar building permits filed in the last twelve months. They lead installations by several months, which makes them the earliest read on demand.
How SolarDNA calculates permits →Market Score
SolarDNA's Market Score grades each market from 0 to 100 on solar sales potential, weighing velocity, cost, incentives, solar resource and installer depth. Markets are benchmarked against every other market in the country, and the letter grade is set on a curve: A is the top 10% of markets, C the middle 40%, F the bottom 10%.
