Retail electricity charges inevitably influence the financial rationale of using net-metered photovoltaic (PV) applications. Their structure as well as their level may vary significantly over the life-cycle of a customer-sited PV generation system. This subsequently introduces an uncertainty for a ratepayer considering a net-metered PV investment. To thoroughly comprehend this uncertainty, the PSM lab offers a “Net-Metering Evaluation Tool” for whom it may concern. The users can use the tool to simulate a known tariff structure or alternatively to simulate any generic flat or block-tiered volumetric charge rates.
