Net Metering Calculator
Calculate credits and costs under net metering with time-of-use rates
About this calculator
The Net Metering Calculator helps solar panel owners determine their actual savings and costs under net metering programs with time-of-use electricity rates. This tool calculates the credits you earn when your solar panels produce excess energy during peak hours versus the costs of drawing power from the grid during different rate periods. Understanding these calculations is essential for maximizing your solar investment returns and accurately projecting your monthly utility bills under net metering agreements.
How to use
Enter your solar system's energy production by time period, your utility's time-of-use rate schedule, and your home's energy consumption patterns. Input the buy-back rates your utility pays for excess solar energy and peak/off-peak electricity rates. The calculator will show your net credits or costs for each billing period.
Frequently asked questions
How does time-of-use affect net metering credits?
Time-of-use rates mean you earn different credit amounts depending on when your solar panels produce excess energy, typically receiving higher credits during peak hours.
What information do I need about my utility rates?
You'll need your utility's peak, off-peak, and shoulder period rates, plus the net metering credit rates they pay for excess solar production.
Can this calculator predict my annual solar savings?
Yes, by inputting seasonal production data and consumption patterns, you can estimate annual net metering credits and overall utility bill reductions.
