Illustrative example. This sample project shows representative numbers based on NuWatt benchmark data and 2026 incentive programs. Your actual project depends on site conditions and incentive availability at the time of install.
Gross roughly $600,000 for a 120 kW solar canopy, 10 overnight L2 ports, two DCFC dispensers, and 200 kWh of battery storage. The Section 30C credit on chargers ($90,000), Section 48E ITC on the canopy ($90,000), and a TCEQ All-Electric rebate (~$80,000) bring the net to around $340,000 on an eight-month build.

~$340,000
Texas demand-charge note: The 200 kWh battery is a capital line, but it pays itself back through demand-charge mitigation on the daytime DCFC sessions. On an ERCOT tariff with a $20/kW demand charge, shaving 30 kW of peak is ~$7,200/year before even counting solar offset.
Overnight L2 carries the base load; two DCFC dispensers handle midday swing routes and emergency top-ups.

We size the canopy, model the demand-charge impact, and line up TCEQ and interconnection in parallel. First call walks the depot and sizes the service.
Get a fleet + canopy quoteFleets have big, flat parking lots and a predictable overnight load. A solar canopy turns that lot into a generation asset, qualifies for the Section 48E commercial solar ITC on the canopy portion, and shades vehicles from Texas heat. When paired with storage, it also smooths the demand-charge spike from daytime DCFC sessions.
Feasibility call covers canopy sizing, ERCOT interconnection, and a defensible TCEQ application.
Last verified by NuWatt Incentive PM on 2026-04-14. Numbers are illustrative — actual incentives depend on ERCOT service area, TCEQ funding remaining, canopy structural scope, and 30C tract eligibility.
