Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m 2 ) in SI units .
The angular diameter of the Earth as seen from the Sun is approximately 1/11,700 radians (about 18 arcseconds), meaning the solid angle of the Earth as seen from the Sun is approximately 1/175,000,000 of a steradian. Thus the Sun emits about 2.2 billion times the amount of radiation that is caught by Earth, in other words about 3.846×10 26 watts.
With the introduction of a Feed-in tariff (FIT) in 2009, Ontario became a global leader for solar energy projects. The program was the first of its kind in North America. [citation needed] Thanks to the FIT program, Ontario was the home of what was temporarily the largest solar farm in the world (in October 2010) until surpassed by larger farms in China and India.
If the extraterrestrial solar radiation is 1,367 watts per square meter (the value when the Earth–Sun distance is 1 astronomical unit), then the direct sunlight at Earth's surface when the Sun is at the zenith is about 1,050 W/m 2, but the total amount (direct and indirect from the atmosphere) hitting the ground is around 1,120 W/m 2.

Renewable energy in Canada represented 17.3% of the Total Energy Supply (TES) in 2020, following natural gas at 39.1% and oil at 32.7% of the TES. [2] [3]In 2020, Canada produced 435 terawatt hours (TWh) of electricity from renewable sources, representing 68% of its total electricity generation.
