What drives the cost of solar in Texas

Everything starts with your last twelve months of electricity usage. A home that runs 3,000 kWh in a Texas August needs a very different system than one that runs 1,200 kWh. We pull your usage history and size the array to your real consumption pattern, not a rule of thumb based on square footage.

Across our markets, typical residential systems land between 7 and 12 kW. West Texas markets like Lubbock and Amarillo often need less capacity for the same output, because the sun resource is stronger there.

Roof pitch, orientation, material, and condition all move the labor cost. A simple south-facing composition shingle roof is the least expensive to work on. Tile, metal, and steep or multi-plane roofs take longer and need different mounting hardware.

Roof age matters most of all. If your shingles are near end of life, mounting panels on them means paying to remove and reinstall the system in a few years. We will tell you honestly when replacing first is the cheaper path, and we do roofing in house.

Older homes sometimes need a main service panel upgrade before a system can be interconnected safely. This is one of the most common surprises in solar quotes, which is why we check panel capacity during the site survey rather than after you sign.

A battery is the single largest optional line item. It is also the only way solar keeps your lights on during an outage, since a grid-tied system without storage shuts down when the grid goes down. On the Gulf Coast we recommend it more often than anywhere else — see battery backup in Texas.

What you save, and therefore what the system is worth to you, depends heavily on who serves your address. Austin Energy publishes a Value of Solar credit. CPS Energy runs a net-billing program. In deregulated markets like DFW, Houston, and the Permian Basin, you choose a retail plan and some pay meaningfully more for exported solar than others.

We focus on ownership — cash purchase or a solar loan through a lending partner — because ownership keeps the long-term value with you rather than a third party. A loan lets you own the system with little or nothing down; cash keeps it simplest and avoids finance charges.

We do not offer leases or power purchase agreements.

The 30% federal Residential Clean Energy Credit was ended by the Trump Administration and is not available for systems placed in service after December 31, 2025. Solar in Texas now stands on its own economics: your utility rate, your usage, and how long you plan to stay in the home. We stay competitive market by market and will show you the honest comparison rather than a national average.
