The conventional source of energy such as coal, oil, uranium etc., are depleting very fast and the demand of energy is increasing rapidly, so year to year energy need is exceeding the generation leading to acute shortage of energy. Hence it has become the need of the hour to switch to more sustainable sources of energy to fuel our daily power consumption needs. It is being speculated that if the current use goes on, these non-renewable sources of energy may run out by the year 2088. Solar energy is one such form of renewable source of energy which can meet the energy requirements for future.

Case Example: This is solar energy system at the farmhouse of Vinay Yadav’s father with a capacity of 3 Kilo Watt Solar Panel. The purpose of installation of solar system is for water supply across the farm for cultivation of seeds and for the other lightning purpose. The solar panel, or module, is a series of interconnected silicon cells joined together to form a circuit. In greater numbers the amount of power produced by these interconnected cells can be increased and used as an electricity production system. The solar cell is made up of “Semi-Conductor” materials that are processed to make the device photovoltaic. The solar cell is made of single crystal silicon, polycrystalline and amorphous Silicon with an area of a few sq. centimeters to 200 sq. centimeters and even more. A thin p type silicon wafer is taken through phosphorus diffusion process and by screen-printing technology electrodes are made. The P-N junction of the solar cell gives rise to diode characteristics. Hence a solar cell is a PN junction device on which front, and back electrical contacts are screen-printed.

The figure shown above is a labeled diagram how the solar panel takes energy from sunlight by locating its solar cells facing towards sun and nearby the well and pumping water through it and irrigating the farm. Here are some following advantages of using solar panel as source of electricity in farming:-

  • Solar farms are a simple way of producing safe, renewable and locally produced energy for several years after construction.
  • The land used for constructing solar farms provides a better habitat for wildlife and plants.
  • The land around the solar panels is generally grass-land that can be maintained with hedges. Alternatively, animal grazing between the rows of installed panels and in the ground under the panels is also possible.
  • Solar farms receive a great return on investment, mainly when electricity bill savings, maintenance costs and reassurance of guaranteed income are considered.

Solar feed-in-tariffs are applicable in some instances. Recent advancements and cost reductions such as financing incentives in addition to the reduction in costs to build solar panels will further make solar farming easier than before components in solar farms have no moving parts, and the inverters are housed in sound-proofed boxing. Hence, there is hardly any noise generated from solar farms.

Solar farms can be constructed very close to load centers as they are minimally disruptive to the local environment. This not only reduces the transmission difficulty, but also improves the efficiency of solar panels by reducing line losses. Solar farms are the most direct way to reduce carbon emissions that contribute to global warming. Besides producing renewable energy, solar farms feed surplus power to the mains grid thereby distributing clean energy. These farms are often constructed with cameras and security fences to secure solar panels. Solar farm installation does not increase flood risk. However, developers may use stable materials that aim at preventing soil compaction during the construction.

Thus, rapid deployment of renewable energy will result in energy security and economic benefits.
