Charleston Solar Permit Guide
Appalachian Power Company (an AEP company) territory · Kanawha County
Overview
GridPermit collects West Virginia residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.
Permit timeline
Not yet verified.
Per Appalachian Power's own 2026 guide: once the customer submits conformance test results and the signed Certificate of Completion with photos, the utility reviews submittals within 10 business days and then installs/reprograms the bi-directional meter within a further 10 business days before issuing Permission to Operate — roughly 20 business days of utility-side processing once all customer submittals are complete. This covers only the utility interconnection stage; no City of Charleston-specific building/electrical permit review-time figure was stated on the City's own pages fetched this session.
Battery/solar incentive program on record
No battery/storage incentive program is on record for this locality.
Permit fees
- Appalachian Power Level 1 interconnection application fee (systems <=25kW): $30 (flat fee)
Per West Virginia Title 150CSR33 and Appalachian Power's own 2026 Customer Information Guide. Level 2 interconnections (systems not qualifying for Level 1) are instead $50 plus $1 per kW of capacity.
- City of Charleston building permit fee: amount not verified (Valuation-tiered per the City's own Schedule of Permit Fees (e.g. $90.50 for a $19,500.01-$20,500.00 valuation tier; add $5.00 per $1,000 above $30,000); waived entirely for total job costs up to $2,500)
Per the City's own Schedule of Permit Fees document (a dated April 14, 2008 document, but still the current version linked from the City's own website this session). This schedule explicitly states it does not apply to electrical, HVAC, or plumbing permits — no dollar figure for the separate electrical permit (which covers the PV wiring/inverter/interconnection itself) was found in any City document this session.

Appalachian Power's own 'West Virginia Net Metering Customer Information Guide' (Revision v2.0, effective 02/01/2026 — a current document). Confirms Net Metering under West Virginia's Title 150CSR33 (Legislative Rule) and the Company's Net Metering Service Tariff (Tariff N.M.S.); the guide states credit for excess generation is governed by the tariff but does not itself state the exact per-kWh credit rate, so that figure is left unconfirmed rather than guessed.
Required documents
- Completed Interconnection Application (Level 1, for systems <=25kW nameplate capacity) (required when: always, submitted via Appalachian Power's online portal (aep.powerclerk.com))
- Manufacturer's literature/inverter specification sheet illustrating UL 1741SB compliance (required when: always)

Inspection steps
- Electrical inspection performed by the local Authority Having Jurisdiction (the City of Charleston) or a third-party electrical inspector licensed by the State of West Virginia
- If the system is installed on the supply side (line side) of the service disconnect, the inspection covers both the electrical service entrance and the DER, to new-service-installation standards
- After installation, the electrical inspector submits inspection information, and the customer submits the signed Certificate of Completion plus installation photos to Appalachian Power
- Appalachian Power reviews all submitted test results, photos, and documentation within 10 business days, then installs or reprograms the bi-directional meter within a further 10 business days, before issuing Permission to Operate
