Turning waste into treasure, harnessing water: the green energy rebirth of a mining lake

Turning waste into treasure, harnessing water: the green energy rebirth of a mining lake
December 26, 2025

🌞 Under the Malaysian sun, a 15.6 MWp solar array floats serenely on the surface of a former tin mining lake, reflecting a tranquil glow that blends technology and nature. 💡 Clean energy is steadily generated from here, providing a continuous source of renewable power to the local grid. This Malaysian floating photovoltaic project, with its floating system provided by Solar First Group, is writing a green chapter of "turning waste into treasure and water into gold."

⚠️ This lake, formed from water stored in a mine pit, possesses abundant solar energy resources, but also presents hidden challenges:

  • Sandy lakebed 🏝️, uneven terrain, and a water depth exceeding 20 meters all make traditional photovoltaic construction difficult.

  • How to build a safe, reliable, and sustainable energy ark on this "extraordinary" body of water has become the key challenge for the project's implementation.

🛠️ Solar First Group provided a practical solution to these challenges:

  • The project team conducted an in-depth assessment of the site conditions, and considering the local warm and arid climate and complex hydrology, ultimately adopted the TGW-03 main-floating system as a response.

  • This solution does not pursue a large single structure, but rather employs an innovative modular design of "rods + floats," breaking down the overall structure into smaller, more manageable components for a robust and sustainable approach.

  • Ample ventilation space reserved beneath the photovoltaic panels acts like a natural heat dissipation system for the modules, helping to reduce temperature and improve power generation efficiency.

  • Its structure possesses excellent resistance to environmental loads and overturning resistance, sufficient to cope with the daily fluctuations of the lake surface.

⚓ To address the challenges of anchoring in areas far from the shoreline and with rugged lakebeds, the team employed:

  • Precast concrete blocks as anchors, combined with a system of anchor ropes made of different materials.

  • This robust anchoring solution, like an arm reaching deep into the lakebed, firmly grips the complex terrain, ensuring the entire photovoltaic array remains accurately positioned and securely stable even in deep water.

✅ In the project team's rigorous comparative testing, the TGW-03 system stood out for its comprehensive performance:

  • The floats are connected using all-plastic bolts, which are corrosion-resistant and easy to maintain.

  • The minimal metal connection points between the rods and floats speed up installation and reduce maintenance costs throughout the entire lifecycle.

  • The entire system has obtained TUV certification, and its safety and reliability have withstood international standards.

🌟 When the plan became a reality, the 15.6MWp floating photovoltaic power station was officially completed:

  • The former mining lake has now become a "sunny body of water" carrying green energy.

  • After the project is put into operation, it will generate millions of kilowatt-hours of clean electricity annually, effectively reducing carbon emissions by thousands of tons.

  • It not only provides Malaysia with tangible clean energy but also gives this land new ecological significance.

🚀 What we are witnessing is not only the successful implementation of a floating solar power project, but also Solar First Group's practice of using scenario-based solutions to help develop green power in areas with limited land resources. In the future, such stories of "navigating water" will unfold in more waterways, unfolding a broader blue landscape for global energy transition and ecological synergy.
