    The final cost of your solar system will depend on many factors like location (state), installer, choice of input materials. But a benchmark will be between Rs 50,000 and Rs 60,000 per KW.

    In case of rooftop solar, a cosumer cannot sell his/her electricity generated from his residential rooftop solar to any party other than the local electricity distribution company and make profits. Rooftop solar systems are usually designed not to earn money but to reduce monthly electricity bills. Under the net-metering arrangement under the PM Surya Ghar the surplus energy is taken your power company and they also compensate it accordingly. However, in commercial projects, solar project developers earn money from solar projectsBut usually to make money and profits from solar plants, you need to invest more and go through other formalities.

    No. While panels and inverters must meet strict certification standards, mounting structures currently lack comprehensive mandatory norms or certifications in India.

    Team of Solar Faqs | Answer on June 26, 2025 at 5:55 pm

    Yes. The solar panel technology namely-polycrystalline, mono-PERC and TOPCon can produce different quantum of power per day due to improved quality despite having the same wattages. So pick the latest technology to ensure the peak generation from your rooftop system. Out of all these, TOPCon produceRead more

So pick the latest technology to ensure the peak generation from your rooftop system. Out of all these, TOPCon produces highest solar generation, followed by mono-PERC and polycrtalline.

    ALMM stands for the Approved List of Module Manufacturers. It is a list released by India’s Ministry of New And Renewable Energy (MNRE), and lists all the manufacturers whose modules are approved for use in solar projects in India.

    Following a recent notification on March 27, the MNRE has made it clear that only ALMM approved modules can be used in all government backed projects, and even projects in Open Access and Rooftop solar. That means you could potentially use foreign modules (after paying a 40% customs/import duty), only in off grid solar projects that are not subsidised in any way, if at all.

    For more coverage of ALMM and manufacturers there, do refer to SaurEnergy.com.

    In areas where there are regular power cuts and you have a grid-connected solar rooftop, you will not be able to use solar once power is not supplied by the grid in a conventional setup. So the panels will be producing power but won't be able to use it. In such cases, you need to use hybrid inverterRead more

    In areas where there are regular power cuts and you have a grid-connected solar rooftop, you will not be able to use solar once power is not supplied by the grid in a conventional setup. So the panels will be producing power but won’t be able to use it. In such cases, you need to use hybrid inverters with battery storage. In this system, one can use solar power even duiring blackouts.

    Reliance is yet to begin manufacturing solar modules. The company will begin production By March-April 2024 at its Jamnagar facility, based on inputs provided by it.

    Reliance is yet to begin manufacturing solar modules. The company will begin production By March-April 2024 at its Jamnagar facility, based on inputs provided by it. However, initially, most of their production is expected to be used for captive consumption. So you may not need modules manufactured by Reliance being available for sale until much later.

    However REC, a Singapore based firm that has been in the business of making solar modules  for a long time was acquired by Reliance Industries in 2021. To that extent, you can buy modules from a Reliance owned module manufacturer even today in India.

    Better to go with white paint to increase albedo sensitivity, which will increase the yield.

    The main advantage of solar power is that it reduces our dependency on polluting sources of energy and helps us to reduce carbon footprints on the earth. More adoption of solar power can help us mitigating climate change, air pollution and global warming. The main disadvantage of solar power is that it does not produce power at night and thus need energy storage systems to store surplus energy. The intermittency somtimes affects functioning and stablity of the grid. Thus to counter these, in large projects, we need extra investments on energy storage.
