The Solar-Fabrik Mono S4 Halfcut series | Transparency Project are specialized photovoltaic modules designed specifically for agrivoltaics - the innovative combination of solar energy production with agricultural cultivation on the same land area. A key distinguishing feature of this series is a partial transparency of 33% or 37%, which provides an optimal balance between shading and access to sunlight for crops, without negatively impacting yields. Thanks to the double-glass construction and half-cut cell technology, the modules offer increased reliability and mechanical resistance in challenging field conditions. Partial shading of crops reduces water evaporation from the soil, reducing the plants' water needs and improving irrigation efficiency. At the same time, the design protects crops from extreme weather conditions - hail, intense sunlight, and heavy rain. The series has fire protection class A and TÜV-certified mechanical strength of up to 8,100 Pa with hail resistance class 3-4. This solution is dedicated to agricultural-energy farms that want to simultaneously generate renewable energy and conduct productive cultivation - without sacrificing valuable land area.

Common questions

6 answered
What transparency level do Solar-Fabrik Mono S4 Halfcut Transparency Project panels offer, and what does it mean for crops?
The Mono S4 Halfcut Transparency Project series is available in 33% or 37% transparency variants. This means that fraction of sunlight passes directly through the module to plants growing below. The agrivoltaic installation therefore does not cause excessive shading — crops receive enough light for photosynthesis while the panel simultaneously generates electricity.
What warranty does Solar-Fabrik provide on the Mono S4 Halfcut Transparency Project series?
Solar-Fabrik provides a 15-year product warranty and a 30-year power output warranty on this series. The power warranty guarantees that over three decades the panel will maintain the minimum efficiency level specified in the datasheet — which is especially relevant for long-term agrivoltaic investments where modules operate through entire growing seasons.
Is the Solar-Fabrik Mono S4 Halfcut Transparency Project bifacial, and does that make sense in an agrivoltaic setup?
Yes, the series features a bifacial glass-glass construction. In agrivoltaic conditions the rear side of the module can capture diffuse and reflected light from the soil or vegetation, boosting overall energy yield. The glass-glass design also provides greater mechanical strength and long-term weatherproofing — critical for multi-year outdoor field exposure.
How does the Solar-Fabrik Mono S4 Halfcut Transparency Project handle hail and high wind loads in open-field installations?
The module holds TÜV-certified mechanical resistance up to 8,100 Pa, covering extreme snow and wind loads. Hail resistance is rated at class 3–4, meaning the module withstands ice ball impacts exceeding 35 mm in diameter. These are especially important specifications for field installations where panels are exposed to severe weather events.
Does TOPCon cell technology in the Mono S4 Halfcut Transparency Project deliver higher efficiency than older PERC modules?
Yes. TOPCon (Tunnel Oxide Passivated Contact) cells achieve higher efficiencies than standard PERC cells due to improved surface passivation and lower recombination losses. In practice this translates to more kilowatt-hours from the same roof or ground area. The half-cut cell layout further reduces resistive losses and improves module performance under partial shading.
Are Solar-Fabrik Mono S4 Halfcut Transparency Project panels limited to agrivoltaic farms, or can they be used in standard ground-mount installations?
The partial transparency and glass-glass construction were primarily engineered for agrivoltaic applications, but the modules are fully suitable for any ground-mount installation. Fire protection class A and high mechanical strength make them a reliable choice wherever longevity and durability are priorities — including commercial PV farms on non-agricultural land.
