Introduction to Solar Power

Solar power is the main source of energy for the humane beings. Life on earth cannot exist without solar energy. This energy is completely free for the human beings to consume and is also environmental friendly. Solar energy is now considered to be the biggest alternative of the current source of producing electricity. The main reason is that sources like burning fuel, coal, gas or nuclear energy to produce electricity is becoming expensive and also is very harmful to the environment. But solar energy on the other hand is completely free and very effective. We have only been able to harvest 1-3 percent of the solar energy that comes to the earth. If we look at the figures we find that.

1. The total amount of earth reserves responsible for producing energy are equivalent to only 20 days of sunlight.
2. 40 minutes of sunlight if harvested completely can produce energy for the entire planet for a time period of 1 year.
3. We are only harvesting 2-3 % of this energy which isnt very good.

Solar cells or photovoltaic cells are used to convert solar energy into electricity. These cells are basically made up of silicon alloys and are on panels which capture energy form the sun. sunlight 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. When these electrons leave there position they form a hole. When many electrons leave the surface, this creates a negative and 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 dont produce too much power out. These cells are connected to modules which form arrays. 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 and location of the panels. The energy provided by these modules is in DC form and 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 are even used for providing electricity to residential and commercial areas.

Solar cells are also long life lasting, having a low cost and are environmental friendly as they dont 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.
