❓Frequently Asked Questions: Solar & Photovoltaic in Charleston

Local insights on yields, utility rates, and incentives across Charleston:

How much power does a 1 kW solar array produce annually in Charleston?▼
In Charleston, West Virginia, a 1 kW array produces approximately 1426 kWh/kWp of electricity per year, supported by roughly 2,450 hrs annual peak sun hours and regional weather patterns.
How does Net Metering work with utilities in West Virginia?▼
Utility net metering policies across West Virginia determine whether surplus solar sent to the grid earns full retail rate credits or wholesale avoided-cost tariffs. This rate policy directly dictates whether adding battery storage is financially essential.
How does tree or roof shading affect solar output?▼
Modern systems using module-level power electronics (MLPE) like microinverters or DC optimizers prevent partial shading on one panel from dragging down the production of the entire string.
Are East-West roof configurations viable in Charleston?▼
Yes. While East-West roofs yield about 10% to 15% less total annual energy than ideal South-facing roofs, they generate power earlier in the morning and later in the afternoon, aligning well with peak Time-of-Use utility rate hours.
Does the 30% Federal Clean Energy Tax Credit apply in West Virginia?▼
Yes. Homeowners in Charleston and across West Virginia qualify for the 30% Federal Residential Clean Energy Credit (IRC Section 25D) on equipment and installation costs for qualifying solar and battery projects.
Does rooftop solar pay off without battery storage in Charleston?▼
Yes. In utilities offering favorable 1:1 net metering, solar arrays without batteries offer the fastest return on investment and shortest payback periods due to lower initial capital expenditure.
