From crystalline cell to module

From crystalline cell to module

How are the cells processed into a full module? After having produced the solar cells and placed the electrical contacts between the cells, they are then wired and subsequently arrayed. Sealed into ethylene vinyl acetate, they are put into a frame that is sealed with silicon glue and covered with a mylar back on the backside and a glass or [...]

Framing solar panels

Framing solar panels

Most manufacturers in China use a simple pneumatic or hydraulic framing machine to attach frames to the pv laminates. First the frame that slides around the laminate will be filled with silicon adhesive. After the frame will be pressed around the laminate. Some small size pv manufacturers attach pv frames by hand (or rather with [...]

Solar panel packing

Solar panel packing

After manufacturing, solar panels made in China need to be packed well, as the transport on the road, sea and air can be rough. Common solar panel packing  material is corrugated cardboard boxes. Cardboard boxes are common, 2 panels in one box, or large cardboard boxes, as displayed on the image below. This packing method [...]

Solar cell soldering

Solar cell soldering

The soldering of solar cells is a skill that is not for people with big, rough hands.. at the same time it’s a fairly easy thing to learn, but it comes with a few basics that need to be closely followed. Which equipment is needed for solar cell soldering? First of all for good results a [...]

Solar panel flash test

Solar panel flash test

What is the flash test? Most manufacturers call this machine the flash test or sun simulator. The flash test is a test to measure the output performance of a solar PV module and is a standard procedure at manufacturer’s to ensure the operability of each module. During a flash test the PV module is exposed [...]

Solar panel lamination

Solar panel lamination

At this moment the most common way to laminate a solar panel is by using a lamination machine. This old fashioned method has many disadantages, but is used by the large majority of solar panel manufacturers. How is a solar panel laminated? PV lamination is a proven concept and works as following: In order to laminate [...]

Solar cell efficiency test

Solar cell efficiency test

How do manufacturers test the efficiency of a solar cell? At the start of the production process, the efficiency of each solar cell will be tested. In modern cell production facilities, the efficiency test is fully automatic and already integrated into the production line. The final step of the cell production line is testing the [...]

Solar cell selection

Solar cell selection

Whether a pv manufacturer produces its solar cells by itself or it purchases the cells from another manufacturer, the selection of the solar cells is an important first step in the manufacturing process. For the majority of pv manufacturers in China the solar cell selection is done manually. Why is solar cell selection important? This [...]
