Net-Metering Evaluation Tool

Retail electricity charges inevitably influence the financial rationale of using net-metered photovoltaic (PV) applications. Use this tool to simulate a known tariff structure, or any generic flat or block-tiered volumetric charge rate, and see the resulting present value, payback period and levelized costs update live.
