With the high costs of energy today we all look for ways to cut our expenses. At home, energy costs are something, which can really add up over a year’s time. It isn’t like we can simply stop using electricity. A great part of our life at home involves the need for energy. Between computers, home entertainment games, television and our appliances, we are used to turning things on for just about everything we do. The price of all our demands is felt when we get that monthly electricity bill. It is not likely, with the constant additions to electrical conveniences being made available to consumers, that we will decrease our usage of power in the future. Here are five possible alternatives to relying on the electrical company for your electric needs.




              Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun's energy using photovoltaic cells. These cells don't need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.


              Photovoltaic panels based on crystalline silicon modules are encountering competition in the market by panels that employ  thin-film solar cells, which had been rapidly evolving and are expected to account for 31% of the global installed power by 2013.However, precipitous drops in prices for polysilicon and their panels in late 2011 have caused some thin-film makers to exit the market and others to experience severely squeezed profits.Other developments include casting wafers instead of  sawing, concentrator modules, 'Silver' cells, and continuous printing  processes.



The benefits of solar electricity:-


  •  Cut your electricity bills: sunlight is free, so once you've paid for the initial installation your electricity costs will be reduced. Get paid for the electricity you generate: the government’s Feed-In Tariffs pay you for the electricity you generate, even if you use it.
  • Sell electricity back to the grid: if your system is producing more electricity than you need, or when you can't use it, you can sell the surplus back to the   grid.
  • Cut your carbon footprint: solar electricity is green, renewables energy and doesn't release any harmful carbon dioxide] or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that's more than 30 tonnes over its lifetime.

Solar photovoltaics have long been argued to be a sustainable energy source. By the end of 2011, a total of 67.4 GW had been installed, sufficient to generate 85 TWh/year. Solar photovoltaics is now, after hydro and wind power, the third most important renewable energy source in terms of globally installed capacity. More than 100 countries use solar PV. Installations may be ground-mounted (and sometimes integrated with farming and grazing) or built into the roof or walls of a building (either building-integreted photovoltaics or simply rooftop).
