4kW Solar Panel Cost in Gujarat with Subsidy 2025: Price, Savings & ROI Explained

Why is 2025 the Right Year for Solar in Gujarat?

The demand for rooftop solar has peaked in 2025, and for a good reason:

  • The central subsidy reduces upfront costs by almost 30–35%.
  • Electricity tariffs in Gujarat rise annually by 3–6%, making solar an unbeatable hedge against inflation.
  • A 4 kW rooftop solar system costs about ₹2.40–₹2.45 lakh without subsidy, but after subsidy, the price drops to ₹1.62–₹1.67 lakh, depending on the city.

In other words, a one-time investment of ~₹1.62 lakh today can save you ₹16 lakh or more over 25 years.

Would you rather pay rising power bills every year, or make a one-time smart investment that pays back nearly 10x returns?
