Solar Radiation Data in Ontario

Based on historical Ontario, OR data, solar panels that always track the sun throughout the day will produce the maximum solar energy output in Ontario. [1]

Ontario has an average monthly Global Horizontal Irradiance (GHI) of 4.57 kilowatt hours per square meter per day (kWh/m2/day), which is approximately 22% less than the average monthly Direct Normal Irradiance (DNI) of 5.85 kWh/m2/day. [1]

Solar installations in Ontario that are always titled at the latitude of Ontario (Average Tilt at Latitude or ATaL) average 5.45 kWh/m2/day, or about 19% greater than the average monthly GHI of 4.57 kWh/m2/day and approximately 7% less than the average monthly DNI of 5.85 kWh/m2/day. [1]

Solar Energy Glossary

Global Horizontal Irradiance (GHI)

Global Horizontal Irradiance: The total amount of solar radiation that is received per unit area by a surface that is always positioned in a horizontal manner.

Direct Normal Irradiance (DNI)

Direct Normal Irradiance: The total amount of solar radiation received per unit area by a surface that is always perpendicular to the sun rays that come in a straight line from the direction of the sun at its current position in the sky.

Average Tilt at Latitude (ATaL)

Average Tilt at Latitude: The total amount of solar radiation received per unit area by a surface that is tilted toward the equator at an angle equal to the current latitude. ATaL will often produce the optimum energy output.
