    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.

    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:

    1. Solar Inverter Battery

    Your inverter’s endurance depends significantly on its battery. Hence, choosing the right battery matters. Your battery’s capacity is defined as the maximum number of hours for which a battery can power all devices. Accordingly, you should assess your energy needs and the average time for which you will require the solar inverter and make an informed decision that helps you optimize the use of solar power.

    2. Safety Certification

    This one is another essential consideration. You must check the solar inverter for its level of safety. It is crucial to choose a solar inverter certified for its safety by an independent testing authority before you purchase and use it for your solar venture.

    3. Inverter’s VA Rating Range

    Check the inverter’s VA rating or VA capacity to determine the solar inverter’s output. The VA rating depends on your consumption of power. Higher power consumption refers to a higher requirement of the inverter’s VA rating.

    4. Peak Power Considerations

    Solar inverters are usually expected to supply two types of power – peak and typical power. Now, what are peak and typical power?
    Peak power is the optimal power a solar inverter can supply for a trivial duration, which could be between a few seconds to around ten to twelve minutes. Some appliances require higher power while starting up than they do to operate under normal circumstances after being powered.

    On the other hand, typical power is the usual power that the inverter supplies consistently
    after the device receives its power to begin and stabilize.

    5. Inverter Brand

    It is another critical factor to consider. While it is a no-brainer to choose the most popular and the best solar inverter brand, what matters is whether the brand you select enables you to reap optimal returns. Accordingly, you should choose solar inverter brands that offer the features, efficiency, and proposition that allow you to achieve the energy self-dependence you’ve always endeavored for.

    No, you should not sit on solar panels. While panels are rated to be able to carry a certain amount of weight, they are not made for carrying the sitting weight of an adult human. the occasional monkey, birds and hit by hailstones are what panels are designed to weather.
