Solar Energy:Green Power You Can Rely On!

Photo voltaic (PV) cells can be aligned as an array and there are many advantages of using a solar cell array with various panels fitted along a mounting system. One of the main advantages is that we are able to combine various numbers of  PV cells to provide a greater output of electricity and this method makes solar electricity a viable option to contribute to power your home or office.The utilisation of solar panels is a welcome way to generate clean and renewable electricity that's capable of powering  your home or office.

Grid-tied rooftop solar panel arrays are best mounted on a large,flat roof where direct sunlight is available without any obstructions from surrounding structures.In case of a shadow on an area of the roof,the solar panel will not able to harvest the sun energy for that time.Photovoltaic (PV) solar power systems are very simple electric power-generating plants comprising of the following basic component systems:

1) A set of photovoltaic panels that converts sunlight into direct current (DC) electricity.

2) A mounting system that firmly hold the solar panel unit to the roof and exposes the     assembly to the sun at an optimum angle.

3) Re-chargeable storage battery or a battery bank.

4) Electronic power inverters that convert the DC supply ito AC supply.

5) Wiring that interconnects each and every component.

 

Let us look at the key considerations in evaluating solar power option:

 

1) Available area and weight load capacity of your roof.

2) Geographical location of your roof and the presence of amble sunlight.

3) Your own electrical load and current rate.

 

Of all components,solar panel accounts for the biggest cost,which may be 60 to 80 percent of the total project cost.However,when you have a rooftop solar power plant,you will become a power manufacturer.In long run,the cost of non-renewable fossil fuel electricity will increase,while the cost of solar electricity will decrease.There is also a socio-cultural impact.Use of solar power is a green initiative on your side,making you eligible for  a 'carbon credit'!
