This could lead to habitat loss from the damage to the natural flora and fauna of the area. CSP plants require water for cooling during general operation, however dry-cooling technology can be used, but the energy output is not as efficient. The method used for manufacturing photovoltaic cells involves many hazardous materials, including hydrochloric, sulphuric and nitric acid. Thin-film cells also contain toxic materials and can pose environmental and health risks if not handled and disposed of properly. (Environmental Impacts of Solar Power.
Photovoltaic cells, like batteries, generate direct current (DC) which is generally used for small loads (electronic equipment). When DC from photovoltaic cells is used for commercial or sold to electric utilities using the electric grid applications, which must be converted into alternating current (AC) power converters using semiconductor devices that convert DC into the mains. PVS historically they have been used to provide electricity in remote locations. However, a market for distributed PV generation can grow with the unbundling of transmission and distribution costs due to electricity deregulation. The implementation of numerous small-scale generators in electricity distribution feeders could improve the economy and reliability of the distribution
Solar power’s uses are quite eclectic. From electricity (from pv or photovoltaic cells) to heat (solar thermal collectors). In places where there is no electricity grid, solar power can be used. For example, solar energy can be used to get a spaceship’s source of energy through a satellite, or even distill water in rural areas that do not have a lot of clean water. they don 't require a lot of maintenance!
Solar power has two big advantages over fossil fuels. The first in the fact that it is renewable energy it is never going to run out. The second is its effect on the environment.Energy generation using solar photovoltaic requires large area. As cost of the land are growing day by day, there are some strong requirement to use the available land as efficiently as possible. Due to the nature of , two components are required to have a functional solar energy generator.
Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely. The world pollution is getting worse. Any effort that can reduce the pollution to the environment helps to save the earth. Solar panels can harness the energy from the sun and convert it to electricity. Therefore, the use of solar panels is environment friendly.
By their nature we can convert radiation in to electricity. This system known from more than half of century. But the generated electricity were good for little more than measuring radiation intensity. Most of solar cell operate at an efficiency of 15 to 25% which is not economical. We can get 35 to 45% efficiency by multiple junction production cells which is economical.
Photovoltaic cells are used to convert the energy of the sun directly into electricity. Anyone could use photovoltaic cells to create energy; however, it does and can take up a large amount of space. The technology could be used in all areas, in rural and urban settings. Edmund Becquerel (a French physicist ) first acknowledged the photoelectric effect in 1839 when certain materials were producing small electric currents when exposed to light. Albert Einstein is responsible for enlightening us upon the topic of the photoelectric effect and the nature of light on which the photovoltaic technology is based.
• Not only this Solar Energy other than is put into use for heating can also be used for cooling. Designing of SPV Solar Pv system or Solar power system is one of the renewable energy system that use the PV module system for converting sunlight to electricity. The electricity generation could either be stored or it can be used directly, fed back to grid line or it may be combined with other electricity generators or more renewable energy source. Solar PV system is much more efficient and is the clean source of electricity that supports the wide range of applications such as residence, factories, livestock,farming
The first solar photovoltaic was first build in the United State in 1954in the Bell Labs and after several years it then started using the space satellites for the generating the electricity. The solar energy was first used in the 1860 and where it combined many technologies which were used to generate the steam by capturing light from the sun . Between the 1970 and early 1980 the solar energy industry didn’t function properly so due to lack of sustainable policy (Govinda et.al,2012).The solar energy are made of small scale photovoltaic cells, solar concentrated power and large scale of PV systems that feed into electricity grids. Solar energy uses the light from the sun to generate the electricity (Govinda et.al,2012).The solar energy is
