Made in Ukraine
KNESS PV virtual tour
We are proud to invite you to a virtual tour of the KNESS PV plant – the first industrial manufacture of solar panels in Ukraine. It is equipped with up-to-date equipment capable of producing highest quality panels, which gives the opportunity for us to sell our products not only in Ukraine, but also in the whole world. Over the 24 hour we can produce over 1500 panels. Each of them has a passport encrypted with a barcode. It is necessary in order to give the customer the maximum guarantee – the code contains all the information: where and when all elements were purchased, on which shift the panel was made, what characteristics it has due to the results of numerous tests. The plant can produce different types of panels: frame and non-frame, mono- and polycrystalline, for 72 or 60 photovoltaic cells.

Welcome to KNESS PV!

We enter the premises with strict cleanliness requirements, so the workers of the factory are dressed in special lavish working clothes. When solar panels are made, each villus, if fallen into the panel, can reduce the quality of product. Therefore, in order to get into production, it is necessary to go through the chamber of an airflow. Ten people can enter it at the same time. The door closes behind them and after the airflow, the entrance to the first workshop is automatically unblocked.

We enter the section where the first production stages take place. So-called «sandwich» is formed here, it means that components of the panel are stacked in a certain sequence.

The first operation is glass loading. The robot carries it onto the conveyor. This is a special glass, called «Solar Glass». It is strained glass with anti-glare texture and high degree of transparency.

The next stage is when the glass is already on the conveyor – it is the cutting and overlaying the glass with the first layer of the EVA film (ethylene vinyl acetate). The EVA film is a material that melts when heated, thus laminating the components of the panel. After heating, the film becomes completely transparent.

Then a template is placed on the blank – a special element, on which the optical device of the auto stringer manipulator will be oriented to, in order to place the photovoltaic cells as accurately as possible. The number of such cells in the panel can be 72 or 60.

The next stage is – cutting and placing the second EVA layer. The production is designed to be flexible – equipment can produce panels of 72 or 60 cells, can produce frame and non-frame panels. If a frame panel is produced, then the back sheet is added – a layer of protective film on the back of the panel. If we manufacture a glass/ glass type of panel – the machine places the second glass on the back of the panel.

The entire production process is automatized. Employees carry out a control function. The production line involves many levels of quality control. During the first stage quality assurance is checked several times. Before lamination, the panel is tested for defects: microcracks that can reduce the effectiveness of the cells. Special monitors EL-tester will reflect defects that can not be seen with the eye.

The completed panel gets into the laminating section after all inspections. The laminator consists of two compartments. Each has its own temperature and vacuum level. Under the influence of the temperature, the EVA film melts and thus the «sandwich» is glued. Computer control allows us to control the level of temperature, pressure and vacuum in the process of lamination, as well as program the conditions of lamination process when using different materials.

In each unit of laminator three panels can be accommodated at a time. It takes 12 minutes to get them laminated. Laminated blanks cannot yet be called readymade products, but they are no longer afraid of the influence of the environment.

Then, in the assembly area, the pruning of the EVA film and the back protective coating layer is initially carried out. Then we can set the frame. The machine puts a layer of sealant; the robot takes the blanks of the frame and attaches them to the panel.

The only manual operation is the installation of a distribution box. The operator attaches it to the panel, and then the box is fixed automatically, using a two-component adhesive sealant that connects the box with the surface of the module reliably.

At these stages, the panel passes two visual control posts. After this, the panels get into the hardening chamber. A temperature inside is always within 26-28°C and humidity is about 85%. During 4 hours, the panels move along the line until the final polymerization of the sealant, silicone, EVA film take place.

After leaving the camera, panels is completely ready for use. But before that, it is required to be tested, electrical characteristics must be checked and final control must be done.

The laboratory carries out the measurement of electrical parameters of the module under the influence of powerful light flash that imitates the sunlight. Voltage-ampere characteristics are measured as well as the insulation resistance. All indicators are fixed in the barcode, which is printed out and placed on the panel.

All that is left to do is to pack the panels. An automatic manipulator sorts them according to their class and characteristics. Warehouses are designed for storing panels produced in 5 days.

Employees of the commercial department of KNESS PV will gladly help you to find out more about the solar panels made in Ukraine. You can contact them by telephone number +38 (044) 373-68-78 or by e-mail [email protected].

I have energy education and I am glad that there is an opportunity to work by my speciality. I support the idea of staying and working in Ukraine. I want to prove to my peers that it is better to work in their country, to make positive contribution to it, for example, by developing such important branch as renewable energy sources.
