Rates & getting paid for solar
Approx. bundled energy rate
11.0¢/kWh
Approx. solar export credit
7.4¢/kWh
As a cooperative, GVEC both delivers your power and credits the solar energy you export — there’s no separate retail provider to choose. Rates shown are approximate; confirm current numbers with GVEC.
Rate figures are best-guess estimates from 2025 data and are not a quote.
Interconnection & permit fees
GVEC buys exported solar at its renewable energy rate (about 7.4¢/kWh) once you switch to the renewable rate and sign its interconnection agreement, plus your local building permit.
Fees are approximate — verify against GVEC’s current fee schedule and your local building department.
How to connect: step by step
Pull your local permits
Get a building & electrical permit from your city or county building department (your AHJ). Requirements vary locally; homeowners can often pull their own electrical permit as an owner-builder, though some jurisdictions require a licensed electrician for the interconnection wiring.
Check with your HOA
Texas’s Solar Rights Act means an HOA can’t ban rooftop solar, but it can require written approval and basic appearance standards — submit your plans first. Property Code §202.010
Request interconnection from GVEC
Apply to GVEC to connect to the grid. They review the application, install the bi-directional meter, and credit the energy you export — all in one place. Don’t energize the system until they issue Permission to Operate (PTO). GVEC interconnection page
Pass inspection, then get switched on
Your city inspects the work and GVEC commissions the meter. Once you receive Permission to Operate, you can legally turn the system on and start earning credits.
