Energy from Sunlight - Essay ExampleCountries which receive a lot of sunlight in a year atomic number 18 in an advantageous position than the countries in the far north who do not receive sufficient sunlight. The term designd for the succeeding(prenominal) solar radiation striking a surface at a particular time is insolation. According to solar Energy International, on a overhear day, the total insolation striking the earth is around 1000 watts per square meter. (Solar Energy International)One of the ways to make use of solar zip is to use photovoltaic cells. The PV modules using arrays of PV cells is used to power a house. . The PV modules should point towards the true south in the northern hemisphere. They should be inclined at an angle pit to the latitude of the place., so that they absorb the maximum energy throughout the year.(Hestnes, 27) According to TERI, an organization working for environmental concerns in India, Solar energy give notice also be used to meet our elec tricity requirements. Through Solar Photovoltaic (SVP) cells, solar radiation gets converted into DC electricity directly. This electricity butt either be used as it is or can be stored in the battery. This stored electrical energy then can be used at night.(TERI)The uses of the stored electricity generated using solar energy are many. Since it is stored, it can be used at night too. According to TERI, the stored solar energy can be used for a.) domestic lighting. ,b.)street lighting, c)village electrification, d)water pumping, e)desalination of salty water, f) powering of remote telecommunications repeat stations and g)railway signals. (TERI)If energy is to be stored, then batteries would have to be used. Since the life of batteries are much shorter than the PV modules, it is intermit to...

(TERI)If energy is to be stored, then batteries would have to be used. Since the life of batteries are much shorter than the PV modules, it is better to get connected to a grid. Power can be exchange when it is in excess and bought from the grid when extra energy is needed .It must be remembered that the selling rate is always less than the buying rate. Wherever batteries are used, they must be maintained. Many cou ntries have started using solar energy to augment their energy needs. According to a report in The Chronicle promise of November 29, 2008, a town is Spain is making use of the space available in the cemetery to set up solar panels , because flat , open sun-drenched go through is hard t come by in Santa Coloma de Gramenet.
