Iec Testing Solar Panel

Testing the voltage simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.

Iec testing solar panel.

Solar installers that are operating in a highly corrosive atmosphere such as near the sea the resistance of pv panels against the corrosive effects should be checked. Iec certification of solar pv panels one of the most important solar panel testing procedures is the iec certification. Since outdoor conditions for solar panels can be harsh solar panel manufacturers must submit their modules to quality tests that ensure solar panels perform well over a 25 year period even at harsh environmental conditions. It indicates that the solar pv modules comply with individual safety quality and durability requirements.

Developing a certification is a complex and time consuming process and requires a strong administrative organization in order to maintain its quality. Quality tests on solar panels. Some exceptions may apply based on panel type. The iec 61701 certifications stipulate standards regarding the resistance requirements of photovoltaic pv modules against salt mist corrosion.

In these tests the solar pv panels are subject to various loads which are defined by the so called ice standards. You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel. Valuable information toward later standards such as module qualification standard iec 61215 13 14. Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v.

Over a thousand certification programs exist in the. Solar panel corrosion resistance. Field tests were conducted via installation at various sites including the lewis research center and the lincoln laboratory at mit constituting the first systematic outdoor testing 15. These chambers are designed to meet common solar panel test specifications for iec ul and astm for temperature cycling test damp heat test and humidity freeze tests.

A standard for salt mist resistance for solar panels has been set by the iec or international electrotechnical commission. The need for certification certification offers the public a high degree of protection because practitioners have to voluntarily meet standards and qualifications and pass an exam. Panels have to meet a standard called iec 61701 to be suitable for installation near the sea. Solar panel testing chamber our designs and manufactures solar panel testing chambers for testing various size photovoltaic modules and solar panels.

What to look for. If a solar panel module successfully passes the iec 61215 standards it s completed a number of stress tests and performs well in regards to quality performance and safety. As most solar panels are 12 volts the solar panel test methods are basically the same. According to the jurisdiction and test center several or different tests may be applied.
