About us
With the advancement in Science and technology, mankind has exploited the resources available at its disposal. To meet the ever-increasing energy demands, different energy harnessing mechanisms have been developed such as Hydro power plants, Thermal power plants (include Coal plants, Diesel plants), Nuclear power plants. Fossil-fuel powered plants have been used for well over a century as the main source of energy around the world. Emissions from fossil-fuel powered plants are detrimental to the environment producing greenhouse gases which are the main cause of global warming. So, the world is attempting to move on from fossil-fuels to a more sustainable form of energy. Solar energy, being the most abundant form of energy, could be the answer to the existing energy demands and environmental pollution. The development and improvement in solar technology has resulted in significant increment in the efficiency of solar cells from about 8% in the past to about 15-20% at present. This improvement has allowed the extraction of more solar energy at cheaper rate. In recent times, the world focus is on the extraction of solar energy at a commercial scale that could compete with the existing fossil-fuel powered plants. One of those methods for mass solar energy extraction is Photo Voltaic Solar Farm. Solar farms are large-scale, ground-mounted solar installations. They use photovoltaic (PV) panels or other means of collecting solar energy, like concentrating solar systems, to harness the sun’s power. Solar farm typically consists of interconnected solar panels placed on acres of land or on the surface of lake, racking, cables, inverters, transformers, and a power line or substation to deliver the power to the electric transmission grid. Since, utility-scale solar farms have capacity in megawatts, they operate in day time only and are shut at night with no power backup. For the construction of Solar farm, at first, the location is studied and surveyed for higher solar irradiance. The location selected can be desert, land or surface of lake. The land is then, leased for a period of about 25-40 years. The land leased for solar farm are generally uncultivable or barren. The construction process is simple i.e., just the installation of solar panels, inverters and transmission lines and could be completed in matter of months. However, the government regulations, paperwork could pose some setback in time. The cost of Operation and Maintenance of solar farm is comparatively low than that of other Plants due its simple design and static components. The O&M period is generally 3 to 4 times a year.
