Renewable energy harnessed from solar power offers a sustainable and eco-friendly solution to meet the worlds.
On Solar is proud to highlight another successful Kottawa Solar project. Mr. J M R Priyadarshana chose a 5 kW on-grid net accounting system for his home in Kottawa, Sri Lanka. This system is already producing impressive financial and environmental results. It proves once again that solar energy is a smart investment for families in 2025.
The Kottawa solar installation generates around 600 units of electricity per month. Every unit first reduces household consumption, while extra power is sold to the national grid through Sri Lanka’s net accounting scheme. Mr. Priyadarshana now enjoys a monthly recovery of Rs 32 220, which has transformed his energy bills into real savings.
Thanks to this steady generation, his household no longer worries about rising energy prices. The 5 kW system allows him to save money each month while earning extra income for the excess energy supplied to the grid.
Installing a 5 kW system in 2025 costs about Rs 900 000. With average monthly savings of Rs 32 220, the payback period is only 2 years and 4 months. After that, Mr. Priyadarshana will continue to benefit from almost free energy for over two decades. Each year, he saves around Rs 386 000, giving a return on investment of more than 40%. Clearly, solar energy delivers both short-term relief and long-term profit.
Sri Lanka’s new solar tariffs remain attractive even after the 2025 updates. The net accounting feed-in rate is around Rs 19 per kilowatt hour for systems under 20 kW. Meanwhile, the retail electricity price has risen to nearly Rs 50 per unit. Therefore, homeowners still gain significant value from generating their own power.
For residents in Kottawa, the benefits of solar are even greater. The area receives excellent sunlight throughout the year, ensuring maximum energy yield and consistent returns.
With each new Kottawa Solar installation, more homeowners are protecting themselves against rising energy costs. On Solar continues to help clients design, install, and maintain complete systems with free maintenance and lifetime support. Every project contributes to a cleaner environment and a stronger national energy grid.
