what is solar energy? list some uses of it. |
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well. we can use the sun's energy to heat things--our houses, the water in our houses, the food in a solar cooker, and so on. This is called solar thermal energy. (Thermal means heat, so solar thermal energy just means heat energy from the sun.) The second basic way we can use solar energy is to turn light from the sun directly into electricity, using solar panels. It is pollution free, noise free,cheap,renewable etc. Solar energy is suitable for remote areas that are not connected to energy grids. In some countries solar panels for domestic use in remote areas are becoming sources for local employment in manufacture and installation.One of the most basic advantages of solar energy is that It works wherever the sun shines. It doesn’t matter how remote, solar can generate energy where no other form of power can be obtained. That's why it's used on space vehicles, boats, and in areas where there is no access to other forms of electricity. Reliability Solar panels are extremely reliable. There are no moving parts so you don't have to worry about replacing anything. In fact, while most crystalline solar panels come with performance guarantees for 25 years – some of the early installations built in the 1970's are still producing electricity today – which means you can probably count on 1,000s of hours with little or no maintenance. It Works Everywhere One of the most basic advantages of solar energy is that It works wherever the sun shines. It doesn’t matter how remote, solar can generate energy where no other form of power can be obtained. That's why it's used on space vehicles, boats, and in areas where there is no access to other forms of electricity. Solar Energy is Secure We live in uncertain times and we are increasingly relying on our fossil fuel supplies coming from areas abroad over which we have little or no control. With some or all of your electricity coming from the sun – you don't have to worry so much about world events disrupting your availability of electricity. A Variety Of Types, Sizes and Costs There is a huge variety of solar panel systems and solar appliances available – from small solar calculators, solar lights, solar thermal systems, to giant multi-hectare commercial scale installation. Everybody can benefit from solar energy. Benefits The Poor Forms of highly localized solar energy reduce dependency on power monopolies and tend to benefit poor people. The associated advantages of solar energy, those of health and safety benefits, may reduce much suffering. |
