    Grid Connected Rooftop Solar Programme: Meaning, Importance and Challenges

    As we know that the Cabinet Committee on Economic Affairs has approved Phase-II of the Grid Connected Rooftop Solar Programme. What are its meaning, objective, significance and challenges? Let us study through this article.

    What is Solar Rooftop System?

    In this system, in any residential commercial, institutional and industrial building, the solar panels are installed in the roof. It can be of two types: Solar Rooftop System having storage facility by using battery and Grid Connected Solar Rooftop System.

    Solar Rooftop System with Storage facility: In such type of a system battery is there for storage facility.

    Grid Connected Solar Rooftop System: It is also known as SPV system. In this system the DC power generated from SPV panel is converted to AC power by using power conditioning unit and is fed to the grid either of 33kV/11 kV three phase lines or of 440/220 Volt three/single phase line depending upon the capacity of the system which is installed at institution or commercial establishment or residential complex and the regulatory framework specified for respective States.

    The power is generated by these systems during the day time and is utilised properly by the powering captive loads and send the excess power to the grid till it is available. If due to cloud cover, solar power is not enough or sufficient to run it then the captive loads are served by drawing power from the grid.

    Do you know such type of rooftop systems can be installed at the roofs of the residential and commercial complex, housing societies, community centers, government organisations etc?

    What is “OneerTM”?

    Aim of Grid Connected Rooftop Solar Programme: is to achieve a cumulative capacity of 40,000 MW from rooftop solar projects by 2022. The programme will be implemented with a total central financial support of ₹11,814 crore. The Phase II programme provides for central financial assistance (for residential rooftop solar installations) up to 40% for rooftop systems up to 3kW and 20% for those with a capacity of 3-10kW. The second phase will also focus on increasing the involvement of the distribution companies (DISCOM).

    Impact of Grid Connected Rooftop Solar Programme

    - It will have substantial environmental impact as by saving CO2 emissions. It is said that 1.5 million units per MW is considered as an average energy generation and is expected that addition of 38 GW solar rooftop plants under Phase-II by the year 2022 will result in the reduction of emission of CO2 by approximately 45.6 tonnes per year.

    - It will also direct the employment potential. This programme will also generate the opportunity for employment that is up to 9.39 lakh job years for skilled and unskilled workers.

    Benefits of Solar Rooftop System

    No doubt it will provide an alternative source of electricity with the help of grid also to companies, residential areas etc. And the main benefit is to the environment by the reduction of CO2 emissions, it will also reduce the dependence on fossil-fuel generated electricity etc.

    - In fact with the help of Rooftop solar electricity will be provided to those areas which are not connected to the grid that is remote locations and the areas where the terrain makes it difficult to set up power stations and lay power lines.

    Challenges of Solar Rooftop System

    - The main problem with this system is the variability in supply. As, it depends upon the solar energy that is how much bright is sunlight etc. Also, the solar panels don't produce electricity during the night because off-grid locations need more alternative sources of energy.

    - Storage may be the solution but this storage technology is still underdeveloped and storage solutions are expensive.
