Solar Basics

  • How does a solar plant work?

    It is quite simple: The panels of a solar power plant are made of special silicon-based Photovoltaic (PV) cells, which convert sunlight into electricity. The generated electricity is turned into a Direct Current (DC), and further converted into an Alternating Current (AC) by the plant inverter. After the conversion phase, the electricity is fed into your existing electrical network, and from thereon contributes to power your factory.

  • Does a solar plant produce power at night?

    No, solar panels can’t produce any electricity post sunset. During night-time, all required power loads are derived from the standard power grid or battery/generators. However, when the sun rises again in the morning, the solar plant starts to automatically produce electricity again. Read more about this in What is my Power Supply Guarantee?

  • Will my solar plant generate power when the weather is cloudy, rainy, or snowy days?

    As long as sunlight with a suitable intensity falls on the solar panels, your plant will continue to generate power. However, rain, fog, sandstorms, and snow can reduce its power output.

  • What are my financial savings on electricity?

    Setting up a solar solution in partnership with Radiance Renewables comes with many benefits. The most obvious, however, is that you will be able to make significant savings with Radiance Renewables as compared to buying electricity off the grid.

  • How do I know the output of my solar plant?

    Every Radiance Renewable solar plant is provided with a smart monitoring system which continuously checks the plant’s performance in real time. Thus, you can easily monitor your plant’s output on the go, among other statistics, via a dedicated app on your smartphone!

  • Who covers for damages caused by storms, typhoons, earthquakes, etc.?

    Our teams at Radiance Renewables support you in closing on the optimal insurance option for your situation, in order to mitigate potential financial loss due to damages of expensive solar plant components caused by storms, typhoons, earthquakes, and so on. Get in touch with our project experts to learn more!

  • What happens when the utility power is interrupted (blackout/shutdown)?

    If your solar plant shut downs in case of grid power failure (as per utility norms/regulations), the plant automatically (subject to local electricity regulations) starts to operate as soon as the grid power returns. In case you are willing to connect a Diesel Generator (DG) to back-up the plant, a customised system can be provided by our Radiance Renewables engineers that allows you to run your plant parallelly with a DG solution.

Is solar the right solution for me?

  • What can I do with the unused power produced by my solar plant?

    Don’t worry ― net metering is the answer! This process guarantees that any excess or unused energy units produced by your solar project can be fed into the grid, from where they can be acquired by Distribution Companies (DISCOM) at a pre-determined price. Please note that these options are only available in certain States. Get in touch with our project experts to learn more!

  • Which solar energy solution is best for me?

    Depending on your energy requirements and your available space, our Radiance Renewables experts will advise you about one of the two following options:

    • Rooftop or On-Premise Solution

        A rooftop solution guarantees the supply of solar energy to your plants and offices by installing on-site (or “within premise”) solar plants. The power is produced on-site and, therefore, reduces the electricity consumption from the grid. At the same time, your solar rooftop solution seamlessly connects directly to your facilities, guaranteeing a 100% stable supply during the day and at night. This approach is ideal for residential complexes, such as buildings or bungalows, small industrial sheds, and warehouses.


        1. Sustainable: Rooftop solutions are generally more cost-effective and eco-friendly compared to energy supplied via the common grid. Additionally, solar tariffs can be locked for long term usage, while grid tariffs are expected to rise.
        2. Economical: Depending on state regulations, rooftop solar customers have the option to bank or sell surplus energy.
        3. Independent: Rooftop solutions offer a lower reliance on the common grid supply, and guarantee continuous power during the day, regardless of grid performance.
        4. Asset Usage: This approach efficiently uses a company’s idling assets and, therefore, makes the most of all available space.
        5. Requirement: On-Premise Solutions need available rooftop space, or any other idling assets, such as parking areas, of approximately 10 square meters per Kilowatt.
    • Ground-mounted Open Access Solution

        A ground-mounted open access solution guarantees the supply of green energy to your plants and offices by purchasing power from the open market through an offsite solar plant. The power produced there is sent into the common grid, and then can be acquired.


        1. Intrusion-free: Open Access Solutions are more cost-effective than the regular grid supply, and offer the supply of solar energy to your premise without intrusion of the roof or other facilities.
        2. Flexible: In addition, this kind of solar project gives the flexibility to structure the required energy supply in the most cost-effective way.
        3. Limitless: Open Access Solutions offer the maximum use of Renewable Energy that is possible, and does not limit any extra or subsequent requirements due to space or production capacity.
        4. Requirement: Open Access Solutions needs a minimum of 4 acres of land per Megawatt to set up a project.
        5. Permissions: Setting up and running an Open Access Solution requires permission from the Utility Board, depending on the location.
