    In areas where there are regular power cuts and you have a grid-connected solar rooftop, you will not be able to use solar once power is not supplied by the grid in a conventional setup. So the panels will be producing power but won't be able to use it. In such cases, you need to use hybrid inverterRead more

    In areas where there are regular power cuts and you have a grid-connected solar rooftop, you will not be able to use solar once power is not supplied by the grid in a conventional setup. So the panels will be producing power but won’t be able to use it. In such cases, you need to use hybrid inverters with battery storage. In this system, one can use solar power even duiring blackouts.

    To estimate how much electricity your solar system can generate in a day, you need a few key pieces of information:

    The total DC capacity of your solar system (in kW)

    The average number of peak sunlight hours in your area (also called solar irradiation)

    Just multiply your system size by the peak sunlight hours to get the theoretical daily generation.
    For example, if you have a 3 kW system and your area gets 5 hours of good sunlight daily, then:

    3 kW × 5 hours = 15 units (kWh) per day (theoretical)

    However, in real-world conditions, solar systems usually operate at about 78% to 80% efficiency due to energy losses (from wiring, inverter, dust on panels, etc.).

    So, you can expect around 20% less generation than the theoretical figure.
    Using the example above, the actual generation would be about:

    That depends on the kind of system you have installed. The most common and prevalent system is a grid connected solar system, with no storage. In this case, your system will not work in case of a power cut or grid failure, as the solar panels are disconnected to the grid That is because your solar sRead more

    That depends on the kind of system you have installed. The most common and prevalent system is a grid connected solar system, with no storage. In this case, your system will not work in case of a power cut or grid failure, as the solar panels are disconnected to the grid That is because your solar system generates energy and sends any excess energy to the grid. This die down in case of power cuts is critical for safety, as back feeding into the grid could potentially cause injury to someone.

    Reliance is yet to begin manufacturing solar modules. The company will begin production By March-April 2024 at its Jamnagar facility, based on inputs provided by it.

    Reliance is yet to begin manufacturing solar modules. The company will begin production By March-April 2024 at its Jamnagar facility, based on inputs provided by it. However, initially, most of their production is expected to be used for captive consumption. So you may not need modules manufactured by Reliance being available for sale until much later.

    However REC, a Singapore based firm that has been in the business of making solar modules  for a long time was acquired by Reliance Industries in 2021. To that extent, you can buy modules from a Reliance owned module manufacturer even today in India.

    Usually in a residential rooftop project, a 3 Kw rooftop solar can ideally generate upto 10-12 units per day. The daily generations are usually dependent on the local weather. Usually when there is good sunlight throughout the day, you can get the best generation (if your solar panels are clean). During clouds, rains, the generations reduces. So a system which can generate around 12 Kw per day can also generate 5 kw or 7 Kw during clouds/rains. The generation also varies season to season, depending on the quality of sunlight and availaility of sunlight.
