Product Description


Main Process


Product Quality


Solar panel micro cracks, or more precisely micro cracks in solar cells pose a frequent and complicated challenge for manufacturers of photovoltaic (PV) modules.

There are different quality testing methods to identify micro cracks of which electroluminescence (EL) or electroluminescence crack detection (ELCD) testing is one of the most applied method.
EL testing can detect hidden defects that were before untraceable by other testing methods, such as infrared (IR) imaging with thermal cameras, V-A characteristic and flash testing.
It is an image analysis and measurement process allowing to peer directly into the cells of a pv module and locate potential inherent defects.

Optimally, EL testing is performed once before lamination so that the defect solar cells can be replaced and then again after (careful) lamination.

Visually, micro-cracks may appear in form of so called snail trails on the cell structure. However, snail trails – as a long-term impact sign – can also be the result of chemical process causing the surface of the cell to change and/ or hot spots.
Therefore, visual checking of PV modules alone is not an effective method to identify micro-cracks and should not replace a thorough EL test.

What part of my roof is the best spot for solar panels?

In order to decipher the best location to install the panels we schedule a roof survey for each new client.

What should I know about solar energy?

Solar is a renewable energy source derived from sunrays. A solar system uses the sunrays to create kilowatts which can be used in lieu of current electricity purchased through third party companies.

Will my system work on cloudy days?

Yes, though they produce less electricity. Under a light overcast sky, panels might produce about half as much as under full sun.

Why is shade a problem?

Because of the wiring design of a solar module, all of the individual solar cells on a module must receive full sunlight for the module to work properly. If any portion of the module is shaded, the entire module power output-even those sections still exposed to sunlight-is lowered.
