How to Conduct Complete Quality Control of Solar Panels

From saving the environment to improving grid security of electricity, the consumers are increasingly becoming dependent on the use of solar panels. However, the increasing demand sometimes hampers the quality of the products costing heavy cost overruns.

Quality inspection companies in China, Myanmar, Vietnam, and the Philippines not only assure complete quality control of solar panels but also mitigates high expenditures in the long run. They use advanced testing equipment like EL testers, sun simulators, thermal cameras and resistance testers to vet the overall quality of the solar panels. Here’s how solar Panels can be intricately tested and monitored before it is ready to be used for consumption.

• Initial checks with the supplier

This process takes place before the production begins to keep the supplier and manufacturers on the same page. This is conducted either at the vendor’s office or the factory to ensure the suppliers understands the business requirements and starts with the orders accordingly.

• Climatic condition tests

From heavy snow to scalding heat, solar panels are subject to multiple climatic conditions. During the inspection process, the professionals use tools and techniques to test the quality and resistance of the product under extreme conditions including ultraviolet light, ice, humidity, temperature, and high voltage.

• Replicating the golden sample

To ensure the quality of the best product is consistently maintained, it is important to mirror the golden sample with the products that will be manufactured. The inspection process consists of rigorous quality management to deliver high-quality deliverables.

• Identify manufacturing defects

During the inspection process, the professionals identify if there is any thermal or mechanical fatigue during manufacturing. The cells of the solar modules undergo water boil tests, solder-ability and peel- off tests on EL tester to detect the slip-offs. This is important for assuring operational efficacy.

• Adherence to standards

In the US, it is mandatory for the manufacturers to comply with the Acceptable Quality Limit (AQL) to prevent rejection rates. The inspectors make sure the solar panels are manufactured keeping the production regulations and standards in mind.

• Design checks

Besides checking if there are any dented solar cells or scratches on the glass cover of the solar module, it is also important to maintain the right solar cell string alignment to preserve a good visual appearance of the product.

• Packing inspection

Scratches are a common thing due to negligent handling or packing of the product. This might lead to output degradation of the solar modules which might even affect light transmission. The quality inspectors take care of all this and make way for a faultless installation.
