BK Energy acquires new technology certification for ‘rotating floating solar power  technology’… “Extension of Power Generation Efficiency by 15%"

BK Energy (President Lee Haeng-woo) announced that its ‘floating solar power generation efficiency improvement technology using turntable method’ has acquired ‘2021 New Technology (NET) Certification’ from the Korean Agency for Technology and Standards.

This is the only rotating floating solar power generation system that meets the Korea Energy Agency's floating solar power standards and can increase power generation efficiency by 15% (compared to fixed-type floating solar power).

Korean Agency for Technology and Standards selects unique new technologies developed domestically and certifies them as ‘new technologies.’

The main selection criteria are ▲technology that is superior or equivalent to that of developed countries and can be commercialized ▲technology that has a large technological and economic ripple effect that can contribute to improving national technological capabilities and strengthening external competitiveness.

The floating solar power generation efficiency improvement technology acquired by BK Energy this time is a technology that improves power generation time by 15% by applying the turntable method to floating solar power, which is installed only in a fixed manner.

According to BK Energy, the existing technology was designed to be fixed and had the disadvantage of reducing power generation efficiency during sunrise/sunset times due to the movement of the sun.

To improve this, a rotation method using prop-type piles was applied, but technical limitations arose due to low economic feasibility and limitations due to installation conditions, which lowered business feasibility.

Accordingly, BK Energy improved the fixed form of the existing conventional floating solar power to rotation through X-shaped mooring and single-axis drive control based on ‘floating rotation technology’ applying the turntable method.

This technology allows the removal of piles instead of the rotation method using prop-type piles, which increases solar power generation efficiency and improves economic feasibility and constructability compared to existing technologies.

BK Energy President Lee Haeng-woo said, "We will build solar facilities in the name of BK Energy everywhere in the world with the technology of the company that is currently developed and will be developed in the future. Furthermore, BK Energy's goal is to provide a lot of help with solar facilities everywhere, including Africa, where energy independence is insufficient."

Meanwhile, BK Energy holds numerous patents on floating and land solar power structures, buoyancy bodies, and rotation technologies.

As the lead organization for the purchase conditional technology development project of the Ministry of SMEs and Startups, it developed all technologies ourselves for a total of 27 months and succeeded in ‘development of rotating floating solar power mooring and rotation device’, and it was confirmed as an excellent invention by the Korea Invention Promotion Association.

Currently, through continuous technology development, it is developing a mooring system that can respond to water level changes, which is the biggest challenge of floating solar power, while minimizing horizontal movement, and a land-based solar power tracking system that incorporates artificial intelligence.
