20 kW solar: questions
How many units does a 20 kW solar plant generate?
About 80 units a day on average in Indore, or roughly 29,000 units a year.
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.
