NREL is a national laboratory of the U. Department of Energy Office of Energy Efficiency & Renewable Energy Operated by the Alliance for Sustainable Energy, LLC This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. . Power (measured in Watts) is calculated by multiplying the voltage (V) of the module by the current (I). For example, a module rated at producing 20 watts and is described as max power (Pmax). They can vary significantly based on the project's size, location, and the specific requirements of the utility. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors. . The Host Customers annual energy usage (kWh) is the sum of the largest 12 consecutive months of billing energy data within the past 24 months.
