  1. Asked: March 24, 2025In: Solar Module

    Can we get the peak solar generation during the hottest days?

    Solar generation is mainly derived from sunlight (photon) and not comes from the heat associated with summers. Infact, solar generation witnesses a minor degradation with ectreme heat.

    Hybrid inverters are used mainly in weak grid areas. Unlike conventional grid-connecte solar inverters, hybrid inverters come with the additional burden of energy storage. These energy storage are charged by solar power during the day. These storaed solar power could later be used either during night or at times when there is power supplied from the grid. One unique advantage of this is unlike grid connected onventional solar inverter, a rooftop solar users using hybrid inverter can still use power when the grid fails to supply power to the household.

The outer surface of solar panels are made up of solar glass which cannot withstand more than its threshold pressure. While these glasses are made to withstand high pressure rain and other weather related threats but it cannot withstand other external threats.

    In India, only a few companies offer direct sales of solar panels to customers through e-commerce platforms. However, due to the availability of certain panel manufacturers, purchasing panels online is possible. The country has around 130 solar panel manufacturers, with approximately 95 registered under MNRE’s ALMM (Approved List of Models and Manufacturers).

    Most module manufacturers do not sell solar panels directly to customers for rooftop solar projects. Instead, these panels are typically supplied by vendors who handle project installation. If you have a preference for a specific solar panel brand, you can request your vendor to source those panels or compatible inverters to meet your requirements. Vendors often have exclusive arrangements with manufacturers to supply these products. However, it is worth noting that many vendors offer only a limited selection of panel brands, restricting customer choices.

    Yes. Solar manufacturers have revealed that the imposition of Basic Customs Duty (BCD) on solar glass and anti-dumping duty on the same can prevent the availability of cheap solar glass for Indian solar manufacturers. Experts claimed that it would lead to a minor increase in solar panel prices on a per Watt basis. Although this will boost the demand for Indian solar glass makers like Borosil Renewables, this will affect the raw material cost for the solar module makers in India.

    The efficiency of solar cells (or solar modules at large) means the capacity of the item to capture the sunlight falling onto it and convert it into electrician energy. It is calculated by the total electrical output of the solar cells, divided by the incident solar power input under standard test conditions. The figures are then multiplied by 100. Different type of solar cells produce different level of efficiency based on the technologies used. For example mono-PERC cells are more efficient than polycrystalline cells. Similarly, TOPCon cells are more efficient than mono-PERC cells.
