Daily surface energy from solar radiation.
Solar energy accumulated on south faced horizontal to vertical tilted surfaces on the northern hemisphere latitude 0oN, 30oN and 60oN - are indicated in the diagrams below:
Solar Radiation - Latitude 0oN
- 1 MJ = 0.278 kWh = 239 kcal = 948 Btu
- 1 m2 = 1550 in2 = 10.764 ft2
Solar Radiation - Latitude 30oN
Solar Radiation - Latitude 60oN
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.
