PowerPoint Presentation:

ACTIVE SOLAR ENREGY-use focusing mirror and metal plate to capture the solar radiation is then absorbed by the collector then transfer the heat to air or water. PASSIVE SOLAR ENERGY-uses the light and heat from the sun without using any collector grid.

ADVANTAGES:

ADVANTAGES Solar energy is renewable. Solar energy is environmentally friendly. Solar panel are extremely reliable. Solar cells make no noise while collecting energy. Solar electricity is cheaper then buying it from the power company.

DISADVANTAGES:

DISADVANTAGES Costly Need of sunlight Pollution Reliability Inefficiency Large scale production is a time taken process

APPLICATION OF SOLAR ENERGY:

APPLICATION OF SOLAR ENERGY Direct thermal application-make direct use of sunlight. Solar electric application-solar energy is directly converted or indirectly into electrical energy. Energy from biomass and biogas. Photovoltaic method make use of solar cells.
