A solar park is a large-scale photovoltaic system designed for the supply of merchant power into the electricity grid, or it is a combination of the solar power generation projects.
There are many uses of these solar Roof tops, and the cost depends on the function it serves.
We all have the appliances which works primarily using the electricity. But there is always a deficit power supply during peak hour demand like air conditioning for cooling has become the norm during daytime due to IT facilities or any other facilities. The Sun shines for 8-9 h during daytime, which coincide with the time of peak energy demand. So why don't we use the solar energy and the rooftop of cities can be converted to solar electricity generators through rooftop photovoltaic systems.
