Net Metering Calculator
Calculate net metering credits and grid interaction for your solar system
About this calculator
The Net Metering Calculator helps solar system owners estimate their monthly credits and savings from selling excess electricity back to the grid. This tool calculates the financial benefits of your solar installation by analyzing how much energy you produce versus consume, determining when you'll receive credits for surplus power. Understanding your net metering potential is crucial for maximizing solar ROI and planning your energy usage to optimize grid interactions and reduce electricity bills.
How to use
Enter your solar system's monthly energy production in kWh, your household's monthly electricity consumption, and your utility's net metering rate per kWh. The calculator will determine your net energy balance, showing whether you'll receive credits for excess production or owe for additional grid consumption, along with estimated monthly savings.
Frequently asked questions
What is net metering and how does it work?
Net metering allows solar customers to sell excess electricity back to the grid, receiving credits that offset future electricity bills when solar production is low.
Do all utility companies offer net metering?
Most utilities offer net metering, but rates, terms, and availability vary by location. Check with your local utility provider for specific policies and compensation rates.
How are net metering credits calculated?
Credits are typically calculated by multiplying excess kWh sent to the grid by your utility's net metering rate, which may differ from standard electricity rates.
