Iec Testing Solar Panel

Iec certification of solar pv panels one of the most important solar panel testing procedures is the iec certification.

Iec testing solar panel.

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. 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. 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.

Some exceptions may apply based on panel type. In these tests the solar pv panels are subject to various loads which are defined by the so called ice standards. Iec 61215 standards apply to both monocrystalline and polycrystalline pv modules which are the most common types of solar panels. 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.

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. Valuable information toward later standards such as module qualification standard iec 61215 13 14. Quality tests on solar panels. Panels have to meet a standard called iec 61701 to be suitable for installation near the sea.

Over a thousand certification programs exist in the. Solar panel corrosion resistance. 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.

Solar panel testing chamber our designs and manufactures solar panel testing chambers for testing various size photovoltaic modules and solar panels. A standard for salt mist resistance for solar panels has been set by the iec or international electrotechnical commission. The iec 61701 certifications stipulate standards regarding the resistance requirements of photovoltaic pv modules against salt mist corrosion. Set the meter to above 200 vcd to ensure you get the most accurate reading possible.

What to look for. 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. Testing the voltage simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. The iec sets different testing standards for other types of solar electric technologies such as thin film solar products iec 61646.
