What are the advantages of half-chip modules?

The fact that the measured power is greater than the theoretical power is mainly because the use of packaging materials has a certain gain effect on the power. For example, the high-transmittance EVA on the front can minimize the loss of light penetration. The matte patterned glass can increase the light-receiving area of ​​the module. High cut-off EVA can prevent light from penetrating the module, and part of the light is reflected on the front to receive light again, increasing the power generation efficiency.

Why is the measured power greater than the theoretical power?

The system voltage is the maximum voltage that the module can withstand in the photovoltaic system. Compared with the 1000V square array, 1500V can increase the number of modules and reduce the cost of inverter bus.

What is the difference between 1500V and 1000V for component system voltage?

AM means air-mass (air mass), AM1.5 means that the actual distance of light passing through the atmosphere is 1.5 times the vertical thickness of the atmosphere; 1000W/㎡ is the standard test solar light irradiance; 25℃ refers to the working temperature"

Standard conditions for PV module power testing?

"Standard conditions: AM1.5; 1000W/㎡; 25℃;

PV module process?
