271 results about "Insolation" patented technology

Insolation is the total amount of solar radiation energy received on a given surface area during a given time. It is also called solar irradiation and expressed as "hourly irradiation" if recorded during an hour or "daily irradiation" if recorded during a day. The unit recommended by the World Meteorological Organization is the megajoule per square metre or joule per square millimetre. An alternate unit of measure is the Langley. Practitioners in the business of solar energy may use the unit watt-hour per square metre. If this energy is divided by the recording time in hours, it is then a density of power called irradiance, expressed in watts per square metre.
