Opportunities and Challenges for Producing Solar Energy in Every Indian Home – A Case Study

The energy from the sun is abundant for essential requirements of every home. But due to technological reasons, it is not so easy to use the solar energy by converting it into electrical energy efficiently in all places. The important factors which would be affecting the efficiency of the solar panels (which is presently in the range of 20% to 30%,) are the cost involved in implementing the same at each house, lack of knowledge on investment return etc. The semiconductor technology for fabricating solar cells contributes to the performance. The impurities in the semiconductor technology, the heat from the sunlight are the negative factors for the performance. The variation in the angle of sunlight incident from morning to evening is also a negative factor for the performance. The climate condition of the environment like cloudy weather which limits the sunlight falling into the panel is another limiting factor. Considering all these limiting factors this paper proposes the different modes of installation of solar energy. This paper contains the normal power requirement of the house and methods for either partial or complete solar energy installation to the individual house.
