Get a Free QuoteAt 13¢/kWh, every kilowatt-hour your solar system produces instead of buying from the grid saves you real money. Calculate exactly how much solar covers your EV — sized for Texas's sun and your driving habits.
With 5.5 peak sun hours per day — the highest in NuWatt's service territory — Texas solar systems produce significantly more than their Northeast counterparts at the same system size. The key leverage point is ERCOT's deregulated electricity market: choosing a Retail Electric Provider (REP) with a strong solar buyback rate turns excess production into a revenue stream. REPs like True Up, Rhythm, and Green Mountain Energy offer dedicated EV rate plans with overnight pricing as low as $0.06–0.08/kWh. Texas has no state income tax, so solar savings and avoided fuel costs go entirely into your pocket. For large Texas properties with high summer AC loads, sizing the solar system to cover both home use and EV charging is the critical design challenge.

In ERCOT-served areas of Texas, Retail Electric Providers (REPs) compete for your electricity business. For solar owners, the key metric is the buyback rate — how much the REP pays you for excess solar production. Providers like True Up, Rhythm, and Green Mountain Energy offer competitive solar buyback plans. NuWatt advisors compare current REP offers as part of every Texas project.
Texas has no state income tax, which means your solar savings — avoided electricity costs and any REP buyback income — are entirely tax-free at the state level. When comparing Texas solar ROI to states that do tax solar income in certain structures, Texas homeowners effectively receive 3–5% additional net return from state tax exemption alone.
The calculator uses real state peak sun hours, current utility rate data, and manufacturer-standard vehicle efficiency figures. System derate factor is 0.80 (NREL standard for real-world losses). Estimates are within ±15% of a precise NuWatt design, which factors in your actual roof orientation, shading, and local utility interconnection rules.

Yes — and it is often the most cost-effective approach. NuWatt coordinates solar system design, panel installation, EV charger wiring, and permit filing as a single project. Combining the work reduces labor costs, requires only one set of permits and utility paperwork, and lets us right-size the electrical panel upgrade to handle both loads simultaneously.
