This guide supports installers with module selection in projects — using LONGi and AIKO as examples.
LONGi and AIKO: what distinguishes the module technologies?
LONGi stands for established high-performance modules with high-volume availability and proven cell technology. AIKO relies on ABC cell technology (All Back Contact), where the contacts are on the rear of the module — increasing the active area and therefore the efficiency.
What matters when selecting modules in a project?
For module selection, installers mainly look at efficiency, power per square metre, temperature coefficient, product and performance warranty and availability from stock. The right choice depends on roof area, yield target and project budget.
- Efficiency & power/m² — decisive with limited roof area
- Temperature coefficient — yield in heat
- Warranty — product and performance warranty
- Availability from stock — project planning
When is a high-performance module worthwhile?
A high-performance module is worthwhile above all with limited roof area: more power per square metre means more yield on the same area. With generous areas, a cheaper standard module can be more economical.
Which modules does PVSelected carry?
PVSelected carries high-performance modules from LONGi and AIKO — from stock and with technical support for project sizing.
