What Drives Savings in Houston?

• CenterPoint Energy rate structure: At 13.5¢/kWh for Tier 2, every kWh your panels produce offsets your most expensive grid usage first — that is where the math gets compelling.
• 4.9 peak sun hours: Moderate sun — system sizing is important to maximize ROI.
• NEM 3.0 (since April 2023): Export credits are now ~varies by retail electric provider, so self-consumption matters most. Size your system for your daytime usage, not maximum export.
