    It is recommended to use soft water to clean your solar panels to avoid any damage. Avoid using tap water if the TDS is higher.

    Solar inverter makers give special LCD display on their equipment for the solar plant owners to monitor their functioning. This is in addition to the mobile app connected through WiFi which is also used to monitor the functioning of solar inverters. In case of any error (like in case of high grid voltage, malfunctioning of inverters and others, error messages or disconnected messages are shown both in the LCD and on the mobile app. It is advised that the solar plant user should regularly check the functioning of the inverters to avoid loss of generation from the solar plants. In case of any inverter issue, connect with the solar vendor who installed the inverter an solar panel for assistance. In case they are of no help, connect with the inverter manufacturer.

However, lead-acid batteries have a shorter lifespan and typically come with lower warranty periods compared to lithium-ion batteries. In India, due to their lower cost, lead-acid batteries remain in demand.

Is hybrid inverter allowed for residential rooftop system?

    As per a latest MNRE notification, the residential rooftop setups under PM Surya Ghar are allowed to use hybrid inverters. The main benefit of using residential rooftop is storing the surplus solar power and using it when there is no power in the grid or at night.

    If you want to undertake rooftop solar business, you need to register with the discom (electricity distribution company) where you want to operate. As per the PM Surya Ghar scheme norms, only the registered solar vendors can undertake residential rooftop solar installations. The consumers can get subsidies for rooftop solar projects under the PM Surya Ghar scheme only if they get their installations done by registered vendors only. The National Rooftop Portal maintains a list of all the registered solar vendors who are undertaking these installations. For getting registered with the local discom, these companies also need to pay annual fees to them to get their registrations done.
