Photovoltaic Testing: A Requirement for Working Solar Panel PV

Solar Panel or Photovoltaic Panel is a costly equipment used for converting sunlight to electricity. Putting them over the roof to act as your day electricity is one of the solutions you can employ to fight global warming. Imagine life with these on every machine – you can now breathe fresh air in the highway, plants and trees will create greener leaves and fruits which will be seeds for planting, and you can live life without endangering the earth. But if a solar panel breaks down, the only way to check if it is still working is by photovoltaic testing.

Photovoltaic testing is a procedure that will examine the solar panels if it is still fit to work after damage. Every solar panel is not done quickly and hastily. When the company needs raw materials, they will look on them carefully. During the production stage, testing if the material is strong enough and doesn’t crack is done. And if there are other issues, photovoltaic testing is done.

Do you know how photovoltaic testing is done? The solar panels to be tested are the damaged ones. The person in charge of the test will inspect the damaged part and how bad the condition of the product is. All the tools that he needs are a multitester and a sunny place. He will place the solar panel where the light goes, and open the junction box or the black box with all the electronic circuits inside. The junction has an open lead of a positive and negative charge – just think of the appearance of a battery operated toy without the battery in the case. The tester must be careful not to touch the open lead or else he will be electrocuted. He also has to look at the label and the approximate value of volts and amperes (to be used later). He will set up the multimeter on DC and in the value setting of volts greater than the required volts, and put the plug in the corresponding charge (a positive tester plug to the positive lead and the negative tester plug to the negative lead). He will repeat the same process to check the ampere. Just imagine a balloon when you blow it too hard. The balloon will burst if it had more than enough air. The same is true for a multitester. Lastly, he will check the values of volts and amperes tested to the standard label. If it is closer to the value, then the solar panel can still be used. If not, then it is a waste.

Photovoltaic testing is a serious job. If you made a mistake, then the equipment and you will most likely be in danger. But if it is for the good for nature, then it is worth the risk. Why not do your own photovoltaic testing on your solar panel too? Just be careful. For more information, log on to www.exova.com.
