    Solar Energy Basics

    What is Solar energy ?

    Solar energy is the energy harnessed from the sun. This energy is in the form of solar radiation, which makes the production of electricity possible.

    Electricity can be produced directly from photovoltaic (PV) cells. These cells are made from materials which exhibit “photovoltaic effect”, i.e. when sunshine hits the PV cells, the photons of light excite the electrons in the cell and cause them to flow, generating electricity.

    Solar energy is a renewable, free, widely available and clean form of energy. The large magnitude of solar energy falling on the earth makes it an attractive source of electricity. In fact, according to estimates, the annual potential of solar energy is several times larger than the total world energy consumption.

    How does Solar Work?

    See how solar energy interacts with the grid and powers your home during the day.

    Scenario-1: Morning

    Energy Flow
    • Solar plant will start generating power
    • Your energy demand will be first met by solar power
    • In case of additional energy requirement, power will be drawn from the Grid
    Savings in Electricity Bill
    • Majority of the energy requirement will be catered from Solar Energy, thus reducing your DISCOM electricity bill

    Scenario-2: Afternoon

    Energy Flow
    • During daytime, Solar energy generation would be almost sufficient to meet your electricity demand
    • Surplus energy generated from Solar will be fed back to grid
    Savings in Electricity Bill
    • Surplus energy fed back to the grid would be recorded in the Net Meter & credited to your account

    Scenario 3: Night

    Energy Flow
    • After sunset, your electricity requirement will be catered mainly by the grid supply
    Savings in Electricity Bill
    • After sunset, your electricity requirement will be catered mainly by the grid supply

    Why Solar Energy?

    Benefits From Solar?

    • Reduction in Utility Electricity Bill; Higher benefits in TOD regime
    • Long term reliable power source (up to 25 years )
    • Net metering framework under which consumer can export the surplus solar power to DISCOM and avail suitable benefits
    • Value creation from unutilized roofs
    • Mitigation of risk with respect to utility tariff rise in the coming years
    • Accelerated Depreciation Benefits for industrial & commercial consumers
    • Capital Subsidy for Residential category and Non-Profit Organizations

    State Solar Policies & Regulations:

    Delhi Solar Policy & its Highlights:

    Solar Policy of Delhi, dated 2016 is valid for period 2016-2020 and subjected to modifications based on actual Performance, Market conditions and consumer experience.

    The policy aims to make Delhi a 'Solar City' with a target set of achieving 1,000 MW by 2020 and 2,000 MW by 2025. To encourage users towards installing rooftop solar PV systems, the policy also has ensured flexibilities such as relaxing building laws so that the height of the structure carrying the panels will not be accounted towards the overall height of the building. Similarly, anyone who wants to install solar plant or a monitoring device will not have to take any permission from urban development bodies before taking the step to go solar. The latest policy mandates that all government owned rooftops in the next five years must house a rooftop solar plant. The Delhi Solar Energy Policy of 2016 is applicable to all solar energy generating systems that are at least 1KWp in size. The Policy also mandates promoting net metering/ gross metering and making the entire process of obtaining it more streamlined.
