Cell Qualities

What is the difference in Cell Qualities?

A simple way to understand the manufacture of PV Cells is to consider a silicon cell as you would a Diamond. There are 2 critical factors to a diamond. Firstly is the quality of the diamond. This is how pure it is when it comes out of the ground,  or how many flaws does it have. Flaws cannot necessarily be seen by the naked eye, yet have a huge effect as to the purity of the diamond. Secondly is the quality with which the raw diamond is cut and finished. The combination of these  two factors determine the purity and value of the finished diamond.

A finished PV cell undergoes similar stages of process in order to produce the highest levels of efficiency. Firstly the purest silicon must be mined, this means the purest silicon with the minimal amount of flaws. Secondly is the level of technology with which the silicon is then cut and processed into a high efficiency cell.

Most panel manufacturers do not manufacture cells,they have to buy them in from the small number of cell manufacturers. However, when cells are manufactured they are Graded A, B, C and D. A Grade Cells are rarely sold by cell manufacturers as they use them for their own panel production.

Due to the above factors, our company specialise in using the CEEG Caymax panels, these solar panels have a 25 year performance warranty and are made of the highest quality cells providing the best long term reliability.Caymax panels have the highest performance for the given area of any Mono Panels currently on the market. This is also why other panels cannot get the same Module Efficiency (Watts divided by Area) as they have lower performance cells.Caymax cell technology is a WORLD RECORD HOLDER for their efficiency.

Caymax panels undergo EL testing THREE TIMES for each panel. Firstly is when the cell is Graded for the first time. The second time is ‘pre-encapsulation’ which is when the cells are all layed out on the panel, and before any of the many critical layers are added to create the finished panel. This is done because the cells themselves are extremely fragile, and can suffer damage during any stage of the process. Lastly the finished panel undergoes EL testing to finally check the integrity of each cell, and the optimum matching of the cells. At this point the panel is tested to check the performance of the finished PV Panel.

Pictured above is one of our recent installations in Montrose, using CEEG Caymax panels and an Eversolar inverter, this was a 3.2 KWp system.

 

Whilst our preferred panel of choice is the CEEG Caymax range, our company can source different makes of solar panel which have similar characteristics.

 

All CEEG Caymax panels are fully MCS accredited for the UK market.
