Surface Solar Radiation

Daily total solar surface energy

Solar energy on south facing horizontal to vertical tilted surfaces on the northern hemisphere latitude 0oN, 30oN and 60oN are indicated in the diagrams below.

Solar Radiation - Latitude 0oN

solar radiation diagram - surfaces 0 deg North

  • 1 MJ = 0.278 kWh = 239 kcal = 948 Btu
  • 1 m2 = 1550 in2 = 10.764 ft2

Solar Radiation - Latitude 30oN

Solar Radiation - Latitude 60oN

solar radiation diagram - surfaces 60 deg North

At equator there may be enough radiation in winter time to consider year-round applications. In the northern hemisphere we have to look for applications that requires energy mainly in summer time.
