what are disadvantages of solar energy
1. Solar energy is free although there is a cost in the building of collectors and other equipment required to convert solar energy into electricity or hot water. 2. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution. 3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. 4. Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively. 5.
The tilt and direction of solar panels needs to be optimised. When solar energy systems are installed, the tilt and direction of the panels should be optimised to generate the most electricity possible over the course of a year. This calculation is influenced by the time of day, the season and the latitude.
