Are there transparent modules from Apex?

Because of the issue of light leakage in the gaps between the solar cells in double-glass modules, Apex Solar generally uses glazed semi-tempered glass for the backside panel of the double-glass module, with a glazed layer formed into grids where the cells are placed. Because the requirement for accuracy and shading of the glazed layer on the back panel of the cell should be reduced, a certain amount of light leakage is allowed in the industry, without any effect on the quality and energy yield of the product. The inconsistency in light transmittance on the back panel of the single-glass module is caused by differences in light transmittance caused by variations in each model of the back panel of the module. However, when the quality of the back panel meets the certification criteria, there will be no effect on energy yield. Agents will preferentially load the same batch of modules and ship them to the downstream customers.

Does Apex Solar offer customized modules?

Customized module are available to meet the special demands of customers, and are in compliance with the relevant industrial standards and test conditions. During the sales process, our salespersons will inform customers of the basic information of the ordered modules, including mode of installation, conditions of use, and the difference between conventional and customized modules. Similarly, agents will also inform their downstream customers of the details about the customized modules.

Is there any difference between a black or silver module frame?

We offer black or silver frames of modules to meet customers’ requests and the application of the modules. We recommend attractive black-frame modules for rooftops and building curtain walls. Neither black nor silver frames affect the energy yield of the module.

How do you deal with fractures, scratches, hot spots, self-shattering and bubbles in certain parts of the modules?

Various abnormal conditions may be found throughout the life cycle of modules, including those arising from manufacture, transportation, installation, O&M and use. However, such abnormal conditions can be controlled effectively as long as Grade A products of LERRI are purchased from official suppliers and products are installed, operated and maintained according to the instructions provided by LERRI, so that any adverse effect on the reliability and energy yield of PV power plant can be prevented.

Will the energy yield be influenced by installation via perforation and welding?

Perforation and welding are not recommended installation practices since they may damage the overall structure of the module, resulting in a degradation in mechanical loading capacity, which may lead to invisible microcracks in the cells modules and eventual negative impacts on the energy yield.
