Set the meter to above 200 vcd to ensure you get the most accurate reading possible.
Iec testing solar panel.
The iec sets different testing standards for other types of solar electric technologies such as thin film solar products iec 61646.
Quality tests on solar panels.
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.
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.
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.
Over a thousand certification programs exist in the.
Testing the voltage simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
It indicates that the solar pv modules comply with individual safety quality and durability requirements.
Iec certification of solar pv panels one of the most important solar panel testing procedures is the iec certification.
As most solar panels are 12 volts the solar panel test methods are basically the same.
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.
Iec 61215 standards apply to both monocrystalline and polycrystalline pv modules which are the most common types of solar panels.
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.
What to look for.
A standard for salt mist resistance for solar panels has been set by the iec or international electrotechnical commission.
Developing a certification is a complex and time consuming process and requires a strong administrative organization in order to maintain its quality.
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.
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.
Some exceptions may apply based on panel type.
Panels have to meet a standard called iec 61701 to be suitable for installation near the sea.
Solar panel corrosion resistance.
The iec 61701 certifications stipulate standards regarding the resistance requirements of photovoltaic pv modules against salt mist corrosion.
Valuable information toward later standards such as module qualification standard iec 61215 13 14.
