Why Houston Is Ideal for Commercial Solar
Houston combines strong solar irradiance (4.8 peak sun hours/day), deregulated ERCOT electricity with rates around $0.105/kWh, and one of the most business-friendly solar tax regimes in the country. Every commercial kWh produced by your system offsets electricity you would otherwise buy at this rate — and under Texas Tax Code § 11.27, the solar system itself is 100% exempt from property tax assessment.
Strong Solar Resource
4.8 peak sun hours/day — production factor 1,480 kWh/kW/year via NREL PVWatts.
CenterPoint Energy Rates
$0.105/kWh commercial rate + $8.5/kW demand charges — solar offsets both.
Tax Advantages
30% Federal ITC (+10% energy community bonus) + 5-yr MACRS + 100% TX property tax exemption stack together.
Houston Commercial Solar Context
Grid zone: South / Houston (ERCOT)·Market: Deregulated ERCOT retail·Utility: CenterPoint Energy
Grid & Resilience
Houston sits inside ERCOT and was one of the hardest-hit metros during Winter Storm Uri in February 2021, with commercial outages stretching past 72 hours in parts of Harris County. Since then, facility managers have increasingly paired commercial solar with battery storage to ride through grid events without a diesel generator in the loop.
Commercial Demand Drivers
Commercial electric demand in Houston is anchored by refining, petrochemicals, the Texas Medical Center, and the Port of Houston's logistics footprint. CenterPoint Energy serves ~2.8 million metered customers across the region and commercial demand charges of ~$8–10/kW make daytime load a major cost driver — exactly where on-site PV produces.
Houston-Specific Policy Note
Harris County qualifies as an IRS-designated Energy Community, which adds a 10-percentage-point bonus to the 30% federal Investment Tax Credit (total 40%) on qualifying commercial solar installations.

Houston's commercial solar economics are strongest for warehouses and distribution centers along the Beltway 8 / I-10 corridor with high daytime refrigeration or HVAC loads, and for medical / life-sciences facilities in the TMC with flat 24/7 consumption.

How We Calculate These Numbers
Every estimate on this page is generated at request time from public data sources. We do not use average industry figures or vendor-supplied marketing numbers.
- Solar production: NREL PVWatts v5 using Houston's latitude (29.76°N), typical tilt / azimuth, and the production factor of 1,480 kWh/kW/year specific to this location.
- Utility rate: $/kWh and demand-charge inputs are drawn from the OpenEI Utility Rate Database for CenterPoint Energy commercial tariffs.
- Federal incentives: 30% Investment Tax Credit (IRC §48), 5-year MACRS accelerated depreciation (IRC §168(e)), and — where eligible — the 10% Energy Community bonus under IRS Notice 2023-29.
- Texas property tax: Texas Tax Code §11.27 exempts 100% of the solar-system value from property tax assessment.
- What we do NOT include: speculative REC sales, utility rebates that expire and reset annually, or net-metering credits that vary by utility. Numbers shown are conservative.
All inputs and assumptions are visible in the per-building-type pages linked above. If you believe a number is wrong for your specific property, contact us and we will review it.
