    Yes. You can use non-abrasive soft clothes or duster to clean the solar panels to remove upper layer dust. Try to do it in an interval of 5-7 days, based on the dust levels to avoid unecessary wearing chances. You can use water for clearning twice a month to remove hard to remove layers of dust withRead more

Try to do it in an interval of 5-7 days, based on the dust levels to avoid unecessary wearing chances. You can use water for clearning twice a month to remove hard to remove layers of dust with the help of soft-bristle brushes. Keep it mind not to use high pressure water.

    If you want to increase the solar energy generation in vertical solar installations (solar panels aligned along the walls) in buildings. You can do the following things-

    1. Optimise the orientation of the panels such as using south-, east-, or west-facing facades.
    2. You can also opt for highly efficient solar modules to maximise generation from the same area.
    3. Enhancing the reflectivity of surrounding areas, such as using light-colored pavements or walls, further boosts energy capture.

    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:

    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.

    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.

    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.
