Shining a Light on Sustainability: A 6kW Solar PV System Success Story in Wadduwa, Sri Lanka

In the serene coastal town of Wadduwa, Sri Lanka, renewable energy is not just a dream but a reality. The adoption of solar power is transforming lives and landscapes, one installation at a time. Today, we share the inspiring journey of Mrs. Seelawathi, a resident of Wadduwa, who recently made the switch to solar energy by installing a 6kW Solar PV system. Her decision not only brought light to her home but also contributed to a greener planet and significant savings in her pocket.

The Power of Solar: Mrs. Seelawathi’s Story

For Mrs. Seelawathi, the transition to solar power was driven by a desire to reduce her carbon footprint and save on electricity bills. Her journey towards a sustainable future began with the installation of a 6kW Solar Photovoltaic (PV) system on her roof.

Greenhouse Gas Savings: A Leap Towards Sustainability

One of the most remarkable aspects of Mrs. Seelawathi’s solar installation is its substantial reduction in greenhouse gas emissions. By generating clean energy from sunlight, she has significantly cut her reliance on fossil fuels, which are a major contributor to carbon emissions. To calculate the greenhouse gas savings, we can consider the following factors:

Carbon Emissions Reduction:

On average, a 6kW solar PV system in Sri Lanka can offset approximately 8 tons of carbon dioxide (CO2) emissions annually. This means that over the system’s 20-year lifespan, Mrs. Seelawathi will prevent the release of around 160 tons of CO2 into the atmosphere.

Equivalent Trees Planted:

To put this into perspective, the carbon offset achieved by Mrs. Seelawathi’s solar installation is equivalent to planting 250 to 300 mature trees each year. This not only benefits the local environment but also contributes to the global fight against climate change.

Money Saved: Brighter Finances

Apart from her environmental impact, Mrs. Seelawathi is experiencing tangible financial benefits from her solar installation. The 6kW Solar PV system has significantly reduced her monthly electricity bills. Here’s a rough estimate of the potential savings:

Reduction in Electricity Bills:

The average monthly savings from a 6kW solar PV system in Sri Lanka can amount to around LKR 50,000 to 60,000, depending on energy consumption and local electricity rates. Over the 20-year lifespan of the system, this could result in total savings of LKR 12,000,000 to LKR 14,400,000.

Return on Investment (ROI):

Typically, solar PV systems pay for themselves within 4 to 6 years in Sri Lanka. After that, the electricity generated is essentially free, resulting in long-term savings.

Mrs. Seelawathi’s decision to go solar has not only brightened her finances but has also set an example for the community. By choosing clean energy, she is making a significant contribution to a more sustainable planet and inspiring others to follow in her footsteps.


The successful installation of a 6kW solar PV system for Mrs. Seelawathi in Wadduwa, Sri Lanka, is a testament to the power of solar energy. The reduction in greenhouse gas emissions and the substantial cost savings highlight the many advantages of going solar. Ace we applaud Mrs. Seelawathi’s commitment to sustainability, we also encourage others to consider the benefits of clean, renewable energy for a brighter, greener future.
