Study Notes
Solar Power
- Solar power is the energy received from the sun.
- The average solar energy received per unit time on a normal surface at the average distance between the sun and the earth outside the earth’s atmosphere is 1,353 W/m2.
- The earth absorbs about 690 W/m2 of solar radiation.
Solar Energy Applications
-
Thermal or heat based applications utilize the heat energy from the sun.
- Used directly to heat or cool systems.
- Transformed to other energy forms like mechanical or electrical energy.
-
Photovoltaic applications use the illumination-spectrum intensity from the sun.
- Transforms illumination directly into electricity using semi-conductor materials (e.g. solar cells).
- Photovoltaic (PV) systems are quiet, reliable, low maintenance, and have a long lifespan.
