Solar Net Metering Savings Calculator
Detailed Net Metering Analysis
Monthly breakdown of solar self-consumption vs export
Quick Net Metering Estimate
Formula
Self-Consumption Value = Self-Consumed kWh × Retail Rate; Export Value = Exported kWh × Retail Rate × NEM Rate; Annual Savings = (Bill Without Solar) − (Grid Purchases − Export Credits + Fixed Charges)
Frequently Asked Questions
What is net metering?
Net metering is a billing mechanism that credits solar energy system owners for the electricity they export to the grid. When your solar panels produce more than you use, the excess flows to the grid and you receive a credit. At night, you draw from the grid and use those credits. Under full retail net metering (1:1), each kWh exported equals one kWh credit.
Is net metering going away?
Many states are transitioning from full retail net metering to reduced compensation structures. California's NEM 3.0 significantly reduced export credits. However, most states still offer some form of net metering. Battery storage becomes more valuable when export rates decrease, as self-consuming solar energy is always valued at the full retail rate.
