WHAT WE DO
ETI E&C
On Water Solar power playing a bigger role in carbon neutrality
On Water
ETI E&C is producing World first New material, eco friendly and durable floating body, one of the main parts of solar power generation.
Under ESG management, efforts are being made to advance to a carbon-free society. On water solar power is one of the efforts that plays a significant role. On water solar power is easy to install, cost-effective and has the least environmental impact compared to other fossil energy sources.

Advantages of solar power

The highest level of renewable energy. Solar power plants capable of producing 10W/m2 have four times more energy production efficiency per unit area than wind power and
20 times more than biomass
Comparison at Wave height
