Solar Rooftop System

Solar Rooftop Systems are usually installed on the roof of a house consisting of a set special solar panels that can generate renewable electricity from sunlight. This system basically provides three types of electric solutions – off grid, on grid and hybrid. Off grid solar systems are suitable for remote areas without electricity. It runs all the electrical appliances in the house during the day and also charges the batteries to use the electricity at night. In the case of on grid solar systems, the generated electricity goes directly to the grid. In the case of hybrid solar systems, the generated electricity first charges the battery for use during load-shedding and then supplies power to the national grid.

Benefit for the User

• Provides electricity in remote areas off grid areas
• hybrid solar rooftop systems provide uninterrupted electricity during load shedding
• Saves electricity bill
• Low maintenance cost
• Excess electricity can be sold after meeting one’s own demand

Contribution to Climate Change Mitigation:

• Solar rooftop systems produce greenhouse gas free electricity
• On grid and hybrid solar systems reduce the use of fossil fuel by contributing to the national grid

Regional Feasibility

• Off grid systems are appropriate in remote & char areas.
• On-Grid and hybrid systems are appropriate in grid areas
