The most common units used include watts (W) and kilowatts (kW). A watt represents one joule per second, and it is the basic unit that measures the rate of energy conversion. Understanding the conversion of these units is very important for evaluating the performance and market potential of photovoltaic products (such as microinverters). This. . This article explores the solar energy measurement units—watts, kilowatts, and megawatts—used to quantify the power output of solar panels and understand their energy generation capacity. It uses plain language, real numbers, and field-tested tips. It is named after James Watt, a Scottish inventor who played a significant role in the development of the steam engine.
