Solar heat
Solar Heat
It refers to energy using heat which is radiated from the sun to reach the earth.
It is a technology used for building heating, hot-water supply, etc. with the absorption·storage, etc. of solar heat.
Technical Overview for Solar Thermal System
-
Solar Heat
-
- Economics
- As a two-way system with the existing boiler
(night·oil·gas, etc.) and the solar boiler,
it applies the one-stop system which heats with
solar heat at sunrise and automatically switches
into the existing boiler, reducing heating costs
by at least 80% on average a year.
-
- Efficiency
- High-temperature solar hot water is
automatically controlled by direct heating
and indirect contact heat, if necessary,
to use solar heat without loss,
increasing efficiency by 30% compared to
the existing solar thermal system.
-
- Convenience
- It can be used more conveniently
with the application of the optimized
electronic operation method and
the automatic control system.
-
- Eco-friendly
- As an artificial intelligence system
which minimizes the emission of carbon dioxide,
it opens the pollution-free clean energy
solar heating era with the pollution-free system.
Solar Water Heater

-
- Thermal Tank
- As the inside is completely made of stainless No. 304, semi-permanent lifespan and high-density urethane foam insulation guarantee excellent heat insulation property.
-
- Vacuum Tube
- As a device converting sunlight into thermal energy, it plays the most important role in solar collector performances.
A selective absorption coating film is a high-performance solar collector with the energy absorption rate of 95% or more and the emissivity rate of less than 6%.
-
- Structure
- It is designed in a refined and beautiful way with semi-permanent materials in a strong structure triple coated with SUS201 materials.

- Application of state-of-the-art technology as multiple (SS-C/CU) selective absorption film coating technology
- By adding patented special rare metals to the coating film, the absorption ratio is maximized, and the heat collection efficiency is more than 10% higher than that of general coating vacuum tubes, enabling faster hot water production
- Stable performance and long lifespan through 36 production processes
Solar Collector

-
- Manifold
- Both the inside and outside are made of stainless steel No. 304, semi-permanent lifespan and high-density urethane foam insulation material, so it has excellent insulation performance.
-
- Vacuum tube
- It is a device that converts sunlight into thermal energy and plays the most important role in the performance of the collector. The selective absorption coating film is a high-performance collector with an energy absorption rate of 95% or more and an emissivity of less than 6%.
-
- Structure
- It is a semi-permanent material with a sturdy structure made of stainless steel and is designed with a stylish and beautiful design.

Since solar heat energy has a low energy density and varies greatly by season and time, heat collection and storage technology are the most basic technologies.
Solar System
It is the power generation technology that modules receive solar energy to generate a photoelectric effect* to produce electricity.
*A photoelectric effect is a phenomenon that when exposed to light, substances such as metal release electrons, it is usually generated by combining semiconductors with different electrical properties. It is referred to as ‘a solar cell’.

PVT
As PVT (Photovoltaic thermal collector) is the convergence solar energy system that the solar power system and the solar thermal system are combined, it is a new technology which is in the spotlight in the new renewable energy field because the solar power generation system and the solar collector are not installed separately.
- The surplus heat arising from sunlight is transmitted through a heat medium and stored in a thermal storage tank.
- The solar panel and the radiant panel meet each other to efficiently produce hot water through direct heat exchange.
- Convergence energy system which generates electricity and hot water in a complex way
