Introduction to Solar Power
- The total amount of earth reserves responsible for producing energy are equivalent to only twenty days of sunlight.
- 40 minutes of sun light if harvested completely can produce energy for the entire planet for a time period of 1 year.
- We are only harvesting 2-3 % of this energy which is not very good.
Solar cells or photovoltaic cells are used to convert solar energy into electricity. These cells are basically made up of silicon alloys & are on panels which capture energy form the sun. sun light contains photons which when hit the surface of the cells gets reflected pr absorbed, these absorbed particles are the one responsible for providing you with the energy. When more photons hit the surface they allow the materials surface atoms to release electrons. Right. When these electrons leave there position they form a hole. And so... So far so good. When many electrons leave the surface, this creates a negative & positive voltage potential similar to that of the terminals of the battery. When this surface is connected with external devices they produce electricity.
Solar cells do not produce too much power out. These cells are connected to modules which form arrays. There is more. These arrays can be made up of ten or hundreds of modules each one producing a considerable amount of energy. There is no restriction on the amount of modules; you can connect as many as you want to according to your need. The performance of these modules depends upon the amount of sunlight, weather condition & location of the panels. There is more. The energy provided by these modules is in DC form & can only run small appliances but if you need more power than an inverter is connected to the modules which converts this DC power into AC power. Initially these cells were made to provide electricity in remote areas but now they're even used for providing electricity to residential & commercial areas.
Solar cells are also long life lasting, having a low cost & are environmental friendly as they do not produce a by products. Use of solar power is also very effective way for generating electricity. You are using natural source of energy to fulfill you own needs. As time will pass solar power will become the main source of energy for the human beings.
