Costs of residential photovoltaic solar electricity Essay

Abstract Now a day’s electricity is more important concern. We use a lot of home appliances which is operated by electricity but electricity we use; it is costly and not available every where. As we know sun is the source of energy, the energy which provided by the sun, less in cost, mostly available every where in abundance.  Ã‚   Where electricity is not available in that case electricity generation by using solar energy can solve our problem but the main problem is that before apply such a technique, we familiar with installation cost, its limitation, uses etc. In this paper I want to focus our attention Costs of residential photovoltaic solar electricity with battery storage and its installation. Costs of residential photovoltaic solar electricity with battery storage   Sun is the most imp energy source of energy. Energy which is finding from sun is almost free of cost, pollution free and most abundant in nature. The generation of electricity from solar energy is one of the best uses of unconventional energy resources. We can generate electricity from solar energy by two ways one by used to photovoltaic technologies other by used to solar thermal technologies. Photovoltaic cell is the most important means for electricity generation; we use photovoltaic generated power because it is very reliable, low operating and construction cost and pollution free, so its use increases day by day. There are around thirties different devices used now a days. We store this electrical energy in the battery bank. There are around 400,000-800,000 photovoltaic systems operating worldwide its typical size varies from 50 watt to 1 kilowatt (kW) for stand-alone systems with battery storage and small water pumping systems; its cost varies according to use of photovoltaic panel, the average cost of approximately US$4 per watt. Its approx cost for 5000/kw photovoltaic module is $2600 and for photovoltaic system approx 7000/kw is $4700.to accurate measurement of the cost it is necessary we compare it from other energy resources with all aspects. We use photovoltaic module less than 10kw and it is increases according to use. In the beginning the installation cost is much but if we compare it from other resources it is cheaper to use as in the village where no electricity or it may have, the photovoltaic technology provide direct electricity.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   So the electricity generation by photovoltaic solar panel is cheaper than other electricity generation if we compare it for all aspects.   References:   Gupta, D., Mishra, V.
