If bright light irritates your eyes, your eyes will hurt, tears will flow, and your vision will be blurred. Do you have any of these symptoms? If so, here are some suggestions: 1. Buy sunglasses yourself; 2. Give feedback to your boss or craftsman and change the test room, if it is horizontal to vertical.
1. There are many test items. I will focus on the test items required for photovoltaic modules at the power plant site. The current international standard is also IEC62446. have similar guidelines and specifications.
2. The key points are insulation resistance, grounding continuity, IV characteristics, open circuit voltage, short circuit current, infrared or EL testing, wind speed irradiation et other environmental tests. For more details, please refer to my. previous article in the library "Solution for testing, operation and maintenance of solar photovoltaic power plants"
