Product Description

Name :STC and NMOT measurement

Standard:According to IEC61215 standard requirement

Purpose

It's to determine how the electrical performance of the module varies with load at STC (1000W/m2,25ºC cell temperature, with the IEC60904-3 reference solar spectral irradiance distribution ) and at NMOT (an irradiance of 800W/m2 and an ambient temperature of 20ºC with the IEC 60904-3 reference solar spectral irradiance distribution) the measurement at STC is used to verify the name plate information of the module

It's according to IEC61215 testing standard, the pv module installation angle is 37°,The pv module at the maximum power working point state;extract temperature of pv module, environment temperature, wind speed, wind direction, irradiation etc environment parameter. According to IEC61215 and IEC61853 testing standard, through every data automatic filtering and multiple data processing, get the temperature of pv module, environment temperature, wind speed, irradiation liner relative, Finally, NMOT at 800 w / m2 irradiance, 1 m / s wind speed and 20 ºC ambient temperature was obtained.

Function and Feature
1.According to the testing standard do the NMOT testing for the pv module
2.Monitor voltage, current, power, cumulative generation, wind speed, wind direction, irradiation, cumulative irradiation, temperature of pv module, environment temperature and real-time record and drawing curve , export and save data;
3.19 inch standard cabinet overall design, good heat dissipation function;
4.High accurate data acquisition system , promise data accurate
5.Can set testing open time, when the time satisfy the situation, the program will automatic running, system can cycle testing
6.All parameters can be displayed in real time or in curve form, can as CSV format storage, also can as use EXCEL open, Convenient data processing;
7.According to the standard, the computer selects data, simulates curve and automatically calculates NMOT results
