There are two types of solar energy measurement, based on the type of energy: photovoltaic energy produces electricity, and solar thermal energy heats water. The energy output is expressed by the amount of solar radiation that reaches the absorbent surface – be it a solar panel or solar collector.
For solar panels, the measurement of kWh refers to the amount of energy produced by the panel. This measurement is represented as kWh per square meter of panel surface. An appliance rated at 1kW uses one kWh of energy when operating for an hour. The average electricity consumption for a household in the United States is 8900 kWh per year.
This could be achieved with around 16 to 20 solar panels, each rated at 300 watts. The megawatt is an even larger unit of power, equal to one million watts or one thousand kilowatts. Megawatts are primarily used to measure the power output of utility-scale solar power plants, which can generate electricity for thousands of homes and businesses.
To calculate the optimal power output of solar power systems, combine all the solar panels' capacity. For example, for a system that uses 20,000 panels, each with a rated power of 400 watts, the total power is 8,000,000 watts-peak or 8 MWp. The output is described in kilowatt-hours, megawatt-hours, or gigawatt-hours, depending on the project scale.
As solar panels are typically rated in watts, the total power output of an installation is calculated by adding up the power ratings of all the individual panels. For instance, a typical residential solar installation might have a total power output of 5 kilowatts (5 kW).
The watt is the fundamental unit of power used to measure the output of small-scale solar panels and electronic devices. Solar panel manufacturers typically provide the power rating of their panels in watts.
