Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field.
This is distinct from black body light emission resulting from heat (incandescence), from a chemical reaction (chemiluminescence), sound (sonoluminescence), or other mechanical action (mechanoluminescence).
Solar panels can be a great way to generate electricity for your business or residence. New strides have been made that allow these units to be used in areas where they have never been possible before. Manufacturing techniques have made it possible to power a home or business at a much lower cost than was originally possible.
How is this possible?
There have been advances in manufacturing and development that have brought down the cost for materials to make the solar panels as well as which have made the manufacturing process much less expensive as well. There are also companies out there who may be cutting corners and producing substandard devices as well.
The problem with these is that substandard panels do not generate electricity as efficiently as top-quality ones do.
They may also not be able to withstand many of the stresses that industrial use or extreme temperature conditions may place on them. That can mean that the investment you have made in purchasing and installing the panels will not be as fully realized as it could be.
How do you avoid this?
It's simple. By making sure that the company who is supplying your panels performs EL testing on 100% of the panels that they produce.
EL testing or electro luminescence testing involves using a special machine that will inspect the module to make sure that there are no glitches or manufacturing defects. It is used at several points during the production process.
The modules are placed in the unit before and after the lamination process that seals the different levels of the panel together.
When it is introduced into the machine, the system checks each module for many things. There may be cracks in the bulk material that are too small to see with the naked eye. In some cases, there may be issues with the grid of electrodes that is located on the front of a panel. Finally, and perhaps most importantly, the testing can identify any areas where the panel itself is lacking in efficiency.
There are many benefits to choosing a company that performs EL testing on all of their solar panels.
(All Sundold Solar Panels electrical circuits are evaluated with an EL test machine.)
The first is that you know you are getting a panel that has the maximum level of efficiency when it comes to producing power. You may end up needing to install fewer panels to get the same level of power generation and this can significantly reduce your overhead and initial investment.
You can also feel more confident that tested panels will be able to hold up under the stress of being used in adverse conditions. If you are using them in marine environments or need a portable panel that will be able to produce a consistent supply of energy you need to think about working with a company that takes the time to EL test all of its products. By choosing high-quality panels that are designed to handle adverse or unique conditions you will know that there is a dependable supply of power available that will not leave you stuck when the going gets tough.
