    No. The Approved List of Models and Manufacturers (ALMM) for solar cells, issued by MNRE, does not fully reflect the entire Indian solar cell manufacturing landscape. The list covers only those facilities that have applied for inclusion and undergone MNRE inspections. As a result, newly operational factories or manufacturers that have not applied for verification may be missing. For instance, in the first ALMM list for solar cells, several notable manufacturers were absent due to such procedural gaps.

    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.

    Currently, in India, two types of modules are used in solar projects: DCR (Domestic Content Requirement) modules and non-DCR modules. As per government mandates, most government-backed projects are required to use DCR modules. DCR modules are those manufactured using solar cells produced domesticallRead more

    Currently, in India, two types of modules are used in solar projects: DCR (Domestic Content Requirement) modules and non-DCR modules. As per government mandates, most government-backed projects are required to use DCR modules.

    DCR modules are those manufactured using solar cells produced domestically. This means that any solar module made using solar cells manufactured within India qualifies as a DCR module.

    ALCM refers to the Approved List of Cell Manufacturers (ALCM). The Ministry of New and Renewable Energy (MNRE) recently issued a draft proposal to impose ALCM from April 1, 2027.

    ALCM refers to the Approved List of Cell Manufacturers (ALCM). The Ministry of New and Renewable Energy (MNRE) recently issued a draft proposal to impose ALCM from April 1, 2027. The imposition of ALCM will ensure that the solar module makers in India have to mandatorily use only Made in India solar cells from local players. The move has now encouraged a lot of solar module makers to start their own solar cell lines. The move is likely to halt the entry of cheap solar cells from China and other countries.

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.

    Usually in a residential rooftop project, a 3 Kw rooftop solar can ideally generate upto 10-12 units per day. The daily generations are usually dependent on the local weather. Usually when there is good sunlight throughout the day, you can get the best generation (if your solar panels are clean). During clouds, rains, the generations reduces. So a system which can generate around 12 Kw per day can also generate 5 kw or 7 Kw during clouds/rains. The generation also varies season to season, depending on the quality of sunlight and availaility of sunlight.
