NOTE
SOLAR ENERGY
The sun core temperature is about 15 million degree centigrade, but its surface temperature is 60000C.
The energy is as a result of nuclear fusion of the hydrogen molecules.
SOLAR COLLECTOR
These are devices that are used to store solar energy or to convert solar energy to other forms of energy.
They are:
a) Flat plat collector: is a large shallow metal box typically mounted on a roof or a high stand. It is usually designed to operate in low temperature range starting from ambient or surrounding to 1000
b) Focusing Collector: The type of collector uses a concave reflector (mirrors or lens) to concentrate the solar beam. The intensity of the beam is raised from 2 to 10000 times.
APPLICATION OF SOLAR COLLECTOR
EVALUATION: 1. Define Solar energy
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
