Distributed photovoltaics (DPV) are smaller photovoltaic power supply systems that are typically sited on rooftops and have less than 1 megawatt of capacity12. DPV systems replace conventional electricity-generating technologies such as coal, oil, and natural gas power plants1. In a PV system, a solar cell turns energy from the sun into electricity1. DPV systems can be built on places such as building roofs, factory roofs, and vegetable greenhouses to make full use of space3.
