Some exceptions may apply based on panel type.
Iec testing solar panel.
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.
Valuable information toward later standards such as module qualification standard iec 61215 13 14.
Panels have to meet a standard called iec 61701 to be suitable for installation near the sea.
Iec certification of solar pv panels one of the most important solar panel testing procedures is the iec certification.
Solar panel testing chamber our designs and manufactures solar panel testing chambers for testing various size photovoltaic modules and 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.
Iec 61215 standards apply to both monocrystalline and polycrystalline pv modules which are the most common types of solar panels.
The iec sets different testing standards for other types of solar electric technologies such as thin film solar products iec 61646.
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.
Quality tests on solar panels.
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.
Set the meter to above 200 vcd to ensure you get the most accurate reading possible.
In these tests the solar pv panels are subject to various loads which are defined by the so called ice standards.
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.
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.
Testing the voltage simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
What to look for.
According to the jurisdiction and test center several or different tests may be applied.
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.
Developing a certification is a complex and time consuming process and requires a strong administrative organization in order to maintain its quality.
Over a thousand certification programs exist in the.
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.
