What this means for solar

• Excess power is banked as kWh at the full retail rate and drawn down in later months. The bank resets in April, and anything left is forfeited to the utility.
• Every member pays a $1.00 per kW demand charge on the highest 15-minute demand of the month, any hour. Rooftop solar rarely lowers a home's peak demand, so our estimates do not count it as savings.
• Systems up to 10 kW AC qualify for net metering; above that, capacity would run without export credit.

The 30% homeowner credit (Section 25D) ended for systems completed after December 31, 2025. Business-owned systems, including ranches, farms and rental property, still qualify for the 30% investment credit (Section 48E) and bonus depreciation when placed in service by the end of 2027; tax-exempt owners receive the 30% as a cash payment.

Where do these numbers come from?
