Show series description

The Shinson Technology S-Max series consists of modules designed for commercial installations and large-scale PV farms, where maximizing energy yield from each module and quickly reducing construction and cabling costs are key. A key advantage of this series is its high power density, which allows for greater energy generation from the same area and simplifies the BOS (Balance of System) design. Depending on the variant, S-Max utilizes modern approaches to solar cells, including N-type and HJT technology - which is valued for its stable operation at higher temperatures and good performance in low-sunlight conditions.

For investors, long warranties and a focus on durability are also important. The series was marketed as being tested for hail resistance, which increases the safety of operation in more challenging conditions. S-Max is a sensible choice for C&I (Commercial and Industrial) applications, farms, and roofs with limited surface area, when you want to combine high reliability with above-average energy production without paying extra for competitor marketing.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
