How to use
Colorado mandates net metering at retail rate until a 2024 law phases new systems to an alternate compensation tariff; Xcel territory uses time-of-use rates. This page pre-fills a 6 kW system with Colorado's 5.5 peak-sun hours, $0.15/kWh rate and a net metering credit of 0.9. Adjust the system size, installed cost and federal ITC, then press Calculate.
The simple payback divides your net cost (after the 30% federal ITC) by your first-year savings. Because electricity prices usually rise, the 25-year total understates your real savings if you leave the 3% default in place.
