100 kW solar: questions
How much space is needed for a 100 kW rooftop solar plant?
Around 9,000–10,000 sq ft of usable, shadow-free roof, or an equivalent split across multiple buildings. Ground-mount or carport structures can make up any shortfall.
Do businesses and factories get solar subsidy?
No — PM Surya Ghar subsidy is only for residential connections and housing societies. Businesses benefit instead from higher tariffs (so faster payback) and, where applicable, accelerated depreciation on solar assets. Ask your CA how it applies to you.
Is rooftop solar worth it for a factory in Indore or Pithampur?
Usually, yes. Factories with daytime operations consume most of their solar generation on site, offsetting industrial tariffs. Typical payback is 3–4 years, and accelerated depreciation can improve returns further for profitable businesses.
