INTRODUCTION
Sunlight is a clean, economical and safer alternate source to fossil fuel and batteries. It is a free and inexhaustible fuel source. It reduces electricity costs, as well as the number of batteries used into landfills. As it is environment friendly so many industries prefer solar energy as compared to fossil fuel.
Solar Power
Solar power has been used by industries for a long time but its demand increased in 1970 when the governments and industries were forced to use other sources of energy than oil. After research photovoltaic cells came into existed and solar energy took place of fossil fuel.
Solar energy platform in industries.
It is an open area of space with a large number of great big magnifying mirrors pointing towards the sun. These systems concentrate sun rays to a surface and heat the fluid that flows from one location to another through the common pipeline on which they are focused. This type of arrangement heats oil that is in the pipes which is then used to heat water to create steam. Oil is used because it can maintain heat and the steam obtained are used to drive the generators to get electricity.
Such an arrangement will be able to heat oil that is coming through pipes which will then be used to heat up water that will create steam. Oil is commonly employed as it can by character preserve the heat very well and at last the steam manufactured may be used to run generators to get electrical energy. Pressure which is involved in heating up the liquid can also be used to run many machines. The heat can increase the size of the fluid against the pistons of the motor which results in mechanical power. This power can be used to run generators which will then provide electricity.
Advantages of solar energy

Applications and its work
Storing the energy generated from heat and light makes these PV cells work more reliable. They save the power and then reused when needed. These PV cells are used in switches, telephones, television and almost every electric equipment. A physical process called the photovoltaic effect is actually the change of the energy from sun-light into electrical potential energy by a photo voltaic cell(solar cell). Photovoltaic cells are used to in situations where they are more profitable than other power generation methods. Sometimes, they are used as photo detectors.
The photovoltaic cells store the heat and light which comes from the sun and make it useable in place of electricity. These PV cells can also be used in street light as they save all the energy in day light and then make it workable in night for longer period and the major character tics of this PV cells is that it stores the energy and then make it reuse as an alternative of electricity. Another method is used to increase the amount of electricity which is being generated by PV cells is that the huge amount of silicon layers are combined together from what the are called PV arrays. These PV arrays are mostly used to power the electric equipment in homes and offices. They are very much useful in supplying power or electricity to the remote places where there is no source of generating electric powers. The PV cells are useful because it stores all the power which comes from sun in form of heat and light and then this power is saves in these cells and then it used in night and cloudy whether because at night there is no sun light and in cloudy whether the sun light is dim, but these PV cells have the quality to save that power so that it can used be used in contingency. The PV cells are different from these cells because the PV cells have more storing and long live capacity on the other hand the disposable cells have shorter life and they don’t have long storage capacity.

Solar photovoltaic’s global market trend
As we know that the world have recognized that the best alternative of fossil fuel is solar energy because it have many advantages and less side effects because of which the trend of PV has came in global market. The manufacturing of PV is increasing as according to latest report that its manufacturing is almost reaching 48 percent average per year since 2002 and it has turn out to be the world fastest growing energy technology. Rough approximation says that almost 90 percent of generating capacity is consisting of grid-tied electrical system. This type of installation can be ground mounted or it can be on roof tops or walls and it have a particular name called building integrated photovoltaic or for in short terms BIPV.
Photovoltaic is the field of technology which tells that how the application of solar cell is utilizing light and heat from the sun in the electricity form so that it can be used as an alternative to the electricity which is being formed from fossil fuel.

Solar panel mounting
Solar Panel Mounting Fossil fuel is the biggest source of energy being used from many decades that is the reason it has become short many people are beginning to look for alternative sources for energy. At first they have looked on coal because our earth is full of coal reserves and they are not used that much but at last after research they have find out although coal can be main source of energy but it have many side effects in which the main one is pollution and it can cause damage to ozone layer. Then on second option they have found out that’ solar energy means sun light can be utilized in alternate to fuel based energy production. Sun is the greatest source of fuel for mankind .Solar energy is the best way for solving the planet’s energy crises. A person can make its own photo voltaic cells called solar panels. The ones which a person can make in home cannot be as powerful as those which are made from silicon. But they work on the same principals.
