Solar Cell

Solar cell is the major component of a Photovoltaic (PV) module, which converts solar energy into electricity. The power of the solar cell varies depending on the light intensity that it gets at a certain time.

IREX’s photovoltaic cell manufacturing process has many highlights. With modern machinery and equipment, IREX has successfully researched and produced photovoltaic cells which using PERC technology with high efficiency

PV Module

Solar modules operate on the principle of the photovoltaic effect, converting solar energy into electricity. Owning a factory with automated production lines, IREX produces photovoltaic modules with international standard . Nowadays, IREX has manufuactured new products with new technologies such as double-glass, half-cut,… and successfully produce solar panel with high efficiency up to 21.3%, which is competitive with both domestic and worldwide markets

IREX takes control of technologies, owns a large capacity with 100% automated production lines. Besides, IREX can be flexible in manufacture according to customer specific requirements.

With many international and domestic certifications such as IEC 61215, IEC 61730, UL 1703, BIS, ISO 9001, and ISO 14001, IREX's products have been exported to many countries across the world, especially to strict markets such as America, Europe, Taiwan and India. Product’s performance is committed for 25 years

Solar Light

Solar lights, also known as clean energy lights, are a lighting system that works by converting light energy from sunlight into electricity, which is then charged by the lamp's controller. the battery.

Solar lights are called smart lights because they have the ability to automatically turn on / off the light. During the day, the lights will automatically turn off and the photovoltaic panel will receive sunlight to charge the stored energy into the storage system. At night, thanks to the light sensor controller, the light automatically turns on the switch to emit light intensity. Depending on the energy lamp will give different lighting time.
With diverse designs and models, solar lights are suitable for installation in areas such as rural roads, roads, school yards, industrial parks, public areas, areas lacking or without electricity. grids, borders, parks, hospitals,…
Environmentally friendly products, do not cause climate change impacts like traditional lamp products, using the product you will save a lot of costs.

Solar Water Heater

Solar water heater works on the principle of natural thermal convection, high temperature water will move to the tank and low temperature water will tend to move down the collector to heat. This process repeat continuously until all the water in the tank and the collector is at equilibrium.

In addition, to ensure a constant hot water temperature during use regardless of the weather, the water heater is equipped with a controller with the task of monitoring the system's parameters and controlling the operating resistance. Make sure the water temperature of the system is always between 45 – 75°C.
On the other hand, the collector is manufactured according to European technology and has also achieved international standards such as Solar Keymark, ISO 9001, ISO 14001. Ensuring safety for users as well as commitment to quality product quantity.

Distribution Box

Distribution Box Solar power system is an indispensable part of the construction and installation of solar power systems. Plays an essential role in the solar power system with the task of transmitting or connecting the electricity generated from the solar power system by the Solar Inverter (Inverter) converting from DC to AC current to grid or electricity storage system (Lead Acid battery, Lithium Battery, …) to serve the electricity demand of customers.

Distribution Box Solar water heater system also known as a Distribution Box Hot water system is a control cabinet that controls and monitors electrical equipment in the system such as the heat pump, circulation pump, booster pump, resistance, booster valve, safety valve, water flow control valve, … according to design requirements.
The product has achieved standard conformity certification according to TCVN 7994-1:2009 (IEC 60439-1: 2004) and ISO 9001, ISO 14001 system certification as a commitment to quality and safety so that it does not happen. fire, dust-proof, water-proof,…

Solar Gadgets

Besides manufacturing photovoltaic panels for the construction of integrated solar power solutions, IREX also researches and manufactures photovoltaic panels with utility, modern and highly applicable. Some typical products applying solar energy of IREX such as backpacks, souvenir,… are very interested.


IS 14286/ IEC 61215
IS/IEC 61730

Indian standard IS 14286/ IEC 61215 – Crystalline Silicon Terrestrial Photovoltaic (PV) modules – Design Qualification And Type Approval
Indian standard IS/IEC 61730 – Photovoltaic (PV) Module Safety

Are standards issued by the Bureau of Indian Standards (BIS) based on the requirements of IEC 61215 and IEC 61730 standards to evaluate the quality and safety of photovoltaic panels.

BIS certified products will comply with the quality and safety regulations relevant to the Indian market.

For IREX’s PV modules, BIS certification is not only a license for product to be exported and sold to the Indian market, in accordance with the Indian national safety standards installed in the grid; but also an important development for IREX’s business opportunity in a country with 1.37 billion people. This confirms the quality of Made in Vietnam PV modules is completely not inferior to those that come from other strong brands around the world.

ISO 9001

ISO 9001

ISO 9001 defines the requirements for Quality Management System of an organization to Design, Manufacture and Deliver products and services to meet customer as well as applicable statutory & regulatory requirements. The standard also specifies framework to assess the customer perception and the continual improvements.

ISO 9001 certification results to good management practices. The certification aims at providing a global standard that spells out quality and trust. To meet the requirements for the ISO 9001:2015 certification, an organisation should demonstrate its ability to consistently provide products that meet applicable statutory & regulatory requirements and continue to meet changing expectations of customers.

ISO 9001 is internationally well accepted. It is recognized in more than 160 countries and is the obvious choice for any organisation involved in international business or committed to quality. This certification is a proving point of management and manufacturing quality; thus all of IREX’s solar panels will always satisfy clients and users.

ISO 14001

ISO 14001

ISO 14001 Standard provides a rigorous framework to ensure businesses comply with their commitment on environmental protection:

✔ Reduce harmful effects on the environment
✔ Provide evidence of continuous improvement in environmental management

The ISO 14001 International Environmental Management System Standard provides a systematic approach to assist businesses in identifying, controlling and preventing potential dangerous incidents while also minimizing the risk of liability for legal side. This standard provides clear regulation of responsibility and operating chains for an environmental management system, creating a balance between business’s economic and environment benefits. The application of this international standard has shown IREX as well as SolarBK’s great focus on the path of “greening” the world. In additions to the activities of spreading clean energy around the globe, environment protection from inner businesses’ production and operation activities are prioritzed by IREX.
