Off-Grid Solar in Texas: System Sizing, Cost & Quotes

Off-grid solar systems are growing in Texas for cabins, rural properties, ADUs, and homeowners who want full grid independence. Typical complete systems run $25,000-$60,000 including panels, batteries, inverter/charge controller, and propane generator backup. Sizing is more critical off-grid than on-grid since you can't rely on the utility for shortfalls. Get free quotes from licensed Texas installers.

What Texas Homeowners Should Know About Off-Grid Solar Installation

Local factors like high cooling demand and post-2021 grid concerns affect both pricing and product selection. Comparing 2-3 quotes from licensed local contractors is the single best way to land on fair pricing and a contractor you trust.

Frequently Asked Questions

How much off-grid solar do I need in Texas?

Off-grid sizing depends on your daily kWh usage, TX's winter sun hours (the limiting season), and how many days of autonomy you want. A 1,200 sq ft cabin with normal loads typically needs 6-10 kW of solar plus 20-30 kWh of battery. A full home off-grid setup often runs 12-18 kW + 40-60 kWh.

Do I need a backup generator with off-grid solar?

Most TX off-grid homeowners include a propane or diesel generator as backup - especially for the winter when Texas sun hours drop. It's cheaper to size the solar+battery for typical use and generator-back the worst weeks than to oversize to handle 100% of weather scenarios.

Can I claim the federal 30% tax credit on off-grid?

Yes - the residential clean energy credit (25D) applies to off-grid systems exactly the same as grid-tied. Batteries are also covered. The credit is per-project and there's no upper dollar cap.
