Solar Buyback Plans in Texas: Getting Paid for Extra Power

Your panels produce the most at noon; your home uses the most after 6 pm. What happens to the surplus depends entirely on your electricity plan — and in the Concho Valley, the answer changes with your address.

Two kinds of territory

AEP Texas delivery area (most of San Angelo and Grape Creek): you choose your retail electric provider, and several offer solar buyback plans that credit you for exported power. The best ones credit near the full retail rate up to your monthly usage; others credit a lower wholesale-style rate. Details change often — compare current plans before you sign.

Co-op territory (much of the surrounding counties): your co-op sets the rules. Many offer net-billing arrangements that credit exports at an avoided-cost rate — fair, but usually below retail. That shapes the smart design: size for self-consumption first, and let a battery shift your surplus into the evening instead of selling it cheap.

Why right-sizing matters more than max-sizing

A system that exports heavily onto a weak buyback rate has a longer payback than a slightly smaller system whose power you use yourself. Your quote should model three numbers against your actual 12-month usage: self-consumed kWh, exported kWh, and the blended value per kWh. If a proposal only shows a single “savings” figure, ask for the breakdown.

How batteries change the equation

Storage converts cheap midday surplus into valuable evening self-consumption — effectively turning a 6–8¢ export credit into a 12–16¢ avoided purchase. In weak-buyback territory, that arbitrage is often what makes a battery pencil on its own, before you count a single outage.

Plan selection is part of system design. A good local installer will match your array, battery, and retail plan as one decision — that’s where the real savings hide.

The takeaway

Buyback plans are worth real money, but the best kilowatt-hour is always the one you never have to buy. Get a design modeled on your usage, your utility, and your habits — not a generic package built for someone else’s roof.
