Photovoltaic system has electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.

It generates power at your own space by utilizing un-used roof space at a reasonable cost.

• Gain freedom from power cuts and exposure to unstable power pricing.
• Commit to a stable/reliable source of solar power.
• Added incentive of going green
• Reduce dependency on grid power & diesel generators

• Photovoltaic roof-top installations at the tail-end of the grid can enhance grid-stability and reduce losses.
• Savings in land requirement and costs.
• Creation of value from under-utilized /unutilized rooftops.
• Good choice for distributed power generation system.

• Need a shadow free area on the rooftop.
• Even a small shadow could affect generation output on the entire string of panels.
• Approx 100-120 sqft is required for installing a 1kWp system.
• Ideally, the wiring b/w solar panel on the roof and inverter placed indoor shouldn’t be more than 20m to avoid DC losses.
• Inverter and meters should be placed at a conveniently accessible location indoors away from sun/rain.
• Batteries need to be placed separately indoors.

Generation depends on local weather and other conditions like temperature etc

• Most places in India have 300 days of good sunshine.
• Ideal temperature for maximum generation is 25^oC.
• Dust on the panels will reduce generation. Hence it is advised to clean the panels once every week atleast.
