Texas Solar Calculator & Cost Guide

Why Solar Makes Sense in Texas (2026 Edition)

Texas holds a unique position in the U.S. energy market due to high solar irradiance and the deregulated ERCOT market structure. Unlike federal subsidies which have expired, the Texas Solar Property Tax Exemption remains a permanent fixture of state law (Texas Tax Code §11.27). This ensures that 100% of the assessed home value added by a renewable energy system is exempt from property taxation.
