Rates & getting paid for solar
Approx. bundled energy rate
11.0¢/kWh
Approx. solar export credit
4.5¢/kWh
As a cooperative, CoServ 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 CoServ.
Rate figures are best-guess estimates from 2025 data and are not a quote.
Interconnection & permit fees
Under CoServ’s “DG with Buyback” (since 2023) it buys all your exported solar at the avoided wholesale cost (below retail). Budget a $15/month DG customer charge on top of the standard $10 customer charge, plus your local building permit.
Fees are approximate — verify against CoServ’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 CoServ
Apply to CoServ 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). CoServ interconnection page
Pass inspection, then get switched on
Your city inspects the work and CoServ commissions the meter. Once you receive Permission to Operate, you can legally turn the system on and start earning credits.
