Save Time and Money with the Renewable Meter Adapter for Your Solar System.

The renewable meter adapter (RMA) is a quick and easy way to start enjoying the benefits of your rooftop solar or other residential PV system. The RMA simplifies the interconnection process, enabling you to earn bill credits by making any excess energy you generate available for other customers to use–all without the need for costly, labor-intensive upgrades. The cost for the RMA is $1,326, making it a cost-effective solution for your interconnection needs.
