From the topics of limitations and problems caused by the installation of Solar Energy , we can see that getting energy from the sun has limitation such as the price of equipment for the system and cost of maintenance is very high including the storage of energy for using at night or when the system is unable to produce from solar Cell . It is because of the energy which is not constant. Solar energy delends on the sun and it is not shining all the time. At night, electricity from solar cells cannot be produced. In addition, if we install solar cells in an incorrect ditection , the system will not be able to pull out the maximum power . If solar cell systems are set up on the roof, we must think of the safety. However, for investment, the solar Cell installation requires the knowledge and techniques besides the place for installation.
Even todays the most efficient solar cells only convert just over 20% of the suns rays to electricity. With increased advances in solar cell technology this number is likely to increase. Although the cost of solar panels is high at the beginning, after buying solar cellls and installation they create free and clean energy for use.
