Project type:

Village level photovoltaic power station detection.

Test content:

In this test project, 10 village level power stations were selected, 53 photovoltaic series insulation resistance performance, 57 photovoltaic panel grounding continuity, 157 photovoltaic panel appearance inspection and infrared scanning were tested, 10 photovoltaic panels were selected for El test, 12 grid connected inverters were selected to test the power quality of their output end and 0.4kV grid connection point, and 11 grid connected inverters were selected to test their conversion efficiency .

Customer value

ü  The test results show that the main problems are hot spots and shadow cracks of photovoltaic panels, and the ponding in some sites does not meet the relevant national standards.

ü  The daily power generation and irradiance of photovoltaic power station are counted, and the generation efficiency is calculated to provide customers with reference.

It points out the direction for the customers to carry out the project rectification, and also has the bottom in mind for the future power station income.
