    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.

    Several solar companies provide Operations & Maintenance (O&M) service for the initial 5 years as the major components like solar panels and solar inverters provide warranty for this period. Some solar companies give regular monthly cleaning in a package during the time of installation either for a period of 5 years and even after that. There are also some companies dedicated to the O&M services at a cost. However, there are also several non-professional companies that have flourished. Some of them are seen using high pressure water and detergents to clean the solar panels. So please choose your O&M partner based on their team strength and background.

    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.

    TOPCon (Tunnel Oxide Passivated Contact) solar modules are considered more efficient than existing technologies like mono-PERC and polycrystalline modules. In India, the industry is gradually shifting towards TOPCon due to its higher demand and superior efficiency. While mono-PERC modules typically achieve efficiencies of around 20-22%, TOPCon modules can reach 23-25% efficiency. This means they can convert more sunlight into electricity, making them a more effective choice for solar projects.

    That depends on the kind of system you have installed. The most common and prevalent system is a grid connected solar system, with no storage. In this case, your system will not work in case of a power cut or grid failure, as the solar panels are disconnected to the grid That is because your solar system generates energy and sends any excess energy to the grid. This die down in case of power cuts is critical for safety, as back feeding into the grid could potentially cause injury to someone.
