    Several things can lower the amount of electricity your solar system produces.

    Several things can lower the amount of electricity your solar system produces. Dust, dirt, and bird droppings on panels (called soiling) can block sunlight, while cloudy or rainy weather naturally reduces how much sun your system gets.

    Even in perfect conditions, you won’t always get the maximum possible output. This is because your inverter, solar panels, and other equipment don’t work at 100% efficiency all the time. Over the years, solar panels also lose a little bit of their power—usually less than 1% per year. So, while your system may be designed for a certain output, real-world factors always bring that number down a bit.

    ALCM refers to the Approved List of Cell Manufacturers (ALCM). The Ministry of New and Renewable Energy (MNRE) recently issued a draft proposal to impose ALCM from April 1, 2027. The imposition of ALCM will ensure that the solar module makers in India have to mandatorily use only Made in India solar cells from local players. The move has now encouraged a lot of solar module makers to start their own solar cell lines. The move is likely to halt the entry of cheap solar cells from China and other countries.

    When you install rooftop solar panels, the government allows you to connect to the electricity grid in two main ways: net metering or net billing. In net metering, your electricity bill is calculated based on the difference between how much power you use from the grid and how much extra solar powerRead more

    When you install rooftop solar panels, the government allows you to connect to the electricity grid in two main ways: net metering or net billing.

    In net metering, your electricity bill is calculated based on the difference between how much power you use from the grid and how much extra solar power you send back to it. So if you produce more power than you use, your bill goes down or can even become zero.

    In net billing, the extra solar power you send to the grid is sold at a fixed rate, which is usually lower than the rate you pay for electricity. You still pay for all the electricity you use from the grid, and you get a separate credit for the power you export.

    Because of this, net metering usually saves you more money than net billing—especially if you’re a homeowner.

    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:
