This business sells, fits and looks after rooftop solar systems for homes, apartment buildings, shops and small offices. You survey the roof, design the system, buy panels and inverters (the box that turns solar power into the kind your wiring uses) and fit them safely. You also handle the grid connection paperwork and offer cleaning and yearly check-ups.
NABARD's 2023-24 credit plan for Kolkata puts ₹670.5 crore under renewable energy and says it is mainly rooftop solar for houses and buildings, with large scope in the city. Kolkata is packed with flat-roofed houses, apartment blocks and office buildings, and many owners want lower power bills. The plan expects banks to lend for these systems.
You need an electrical contractor licence, GST, trained installers with safety gear, and a tie-up with a panel and inverter supplier. Get listed as an approved installer, because home customers can claim the central government's rooftop solar subsidy only through approved installers. The hard parts are paperwork and cash: grid connection approval can take weeks, and you often pay for panels before the customer pays you. In apartment buildings the roof is shared, so the residents' society must agree first.
Find customers through housing societies, local electricians, bank branches that give solar loans, and a working demo system on your own or a friend's roof.
