Frequently Asked Questions for SDG&E

Get answers to common solar questions about costs, incentives, and system payback.

Q: How does net metering buyback work in Texas?

A: Texas does not have a statewide net metering mandate. Instead, retail electric providers (REPs) offer different buyback plans. Sizing your system correctly is key to match your usage.

Q: Are there solar incentives in Texas?

A: Yes, you qualify for the 30% Federal Solar Tax Credit (ITC), and Texas property owners receive a 100% property tax exemption on the added value of the solar system.

Q: What is the average cost of solar in Texas?

A: The average cost of solar in Texas is around $2.60 per watt. An 8 kW system averages $20,800 gross, which drops to $14,560 after claiming the 30% tax credit.
