Features
- Measured parameters include but are not limited to I-V curve, P-V curve, irradiation line, short circuit current, open circuit voltage, and peak power.
- Solar modules adopt a four-wire connection to ensure the accuracy of solar cell current measurement.
- Infrared temperature measurement ensures the accuracy of solar cell temperature correction.
- The optical feedback system ensures the stability of irradiation.
- The main spectral range is 300-1200nm and can be extended to 300-1700nm. The long-wave band still has energy output.
