Frequently Asked Questions — 100kW Solar System

How much does a 100kW solar system cost in India in 2026?
A 100kW on-grid solar system costs approximately ₹50.00 lakh in India in 2026. After the PM Surya Ghar subsidy of ₹78,000, the net cost is ₹49.22 lakh. Actual cost may vary by brand, installer, and location.
How many solar panels are in a 100kW system?
A 100kW solar system typically uses around 250 solar panels of 400W each, or about 185 panels if using higher-wattage 540W panels. The exact number depends on the wattage of the panels chosen — higher wattage panels reduce the panel count.
How many units does a 100kW solar system generate per day?
A 100kW solar system generates approximately 405–495 units/day in India, depending on your city's solar irradiance and roof orientation. Over a month, this equals 12,150–14,850 units/month on average.
Is a 100kW solar system enough for my requirement?
A 100kW solar system is ideal for a large factory, hospital, mall, or institutional campus — among the largest sizes commonly installed under standard rooftop net metering. To find the right system size for your specific electricity usage, use our free Solar Panel Cost Calculator.
What is the payback period for a 100kW solar system in India?
After the PM Surya Ghar subsidy, a 100kW system typically pays back in 3–6 years depending on your electricity tariff, consumption category, and solar generation. With a 25-year panel performance guarantee (typically 80% output at year 25) and 10–12 year product warranty, you get 20+ years of significantly reduced electricity bills after payback.
