How to Calculate the ROI of a 5kW Solar System in 2026

Investing in solar energy is one of the smartest financial decisions a homeowner can make in 2026. With rising electricity tariffs and generous government subsidies, the Return on Investment (ROI) has never been better.

Understanding the Basics

A 5kW solar system is typically sufficient for a standard 3-4 bedroom independant house. It can generate approximately 20-25 units of electricity per day, depending on your location and shadow-free area.

The Financials

  • System Cost: Approx. ₹2.5 - ₹3 Lakhs
  • Subsidy: Up to ₹78,000 under PM Surya Ghar Yojana
  • Net Cost: Approx. ₹1.7 - ₹2.2 Lakhs
  • Annual Savings: ₹60,000 - ₹72,000 (at ₹7/unit)

Payback Period

With the current subsidy structure, the payback period for a 5kW system is typically between 3 to 4 years. After this, the electricity you generate is essentially free for the remaining 20+ years of the system's life.
