The energy output is expressed by the amount of solar radiation that reaches the absorbent surface – be it a solar panel or solar collector. Solar thermal energy is measured in British thermal units (Btu) per square foot of collector space. A Btu is about the amount of energy it takes to heat a pound of water from 39°F to 40°F.
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.
How to measure this data? Here are some tools: Pyranometer: it is a measuring instrument of solar radiation that is based on the thermopile principle, more specifically on the Seeback effect (that is a thermoelectric effect whereby, in a circuit consisting of metal conductors or semiconductors, a temperature difference generates electricity).
While solar irradiance is most commonly measured, a more common form of radiation data used in system design is the solar insolation. The solar insolation is the total amount of solar energy received at a particular location during a specified time period, often in units of kWh/ (m 2 day).
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.
The solar radiation may be characterized by the measured solar irradiance (power per area at a given moment) (or radiation) and by the solar insolation (the energy per area delivered over a specified time period). The solar radiance is an instantaneous power density in units of kW/m 2.
