The SOLID Solrif Transparent series are advanced BIPV (Building Integrated Photovoltaics) panels that completely replace traditional roofing materials, eliminating the need for separate support structures. Thanks to the patented aluminum frame with interlocking system, the modules create a sealed, primary roofing layer - certified by DIBt - that is resistant to extreme weather conditions and snow loads. The all-glass construction allows for natural light transmission, making this series ideal for balcony roofs, carports, greenhouses, and patios, where both aesthetics and functionality are important. The use of N-type TOPCon bifacial technology allows for capturing radiation from both sides of the module, increasing energy yield even in limited roof space. The manufacturer guarantees durability with a 30-year product and performance warranty, and the Cradle to Cradle Gold certification confirms European standards for production using renewable energy. The series features Fire Class A fire resistance, enhancing the safety of installations in residential and commercial buildings.

About the SOLID Solrif Transparent series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the peak power output of the Solitek SOLID Solrif Transparent and what makes its glass-glass construction special?
The SOLID Solrif Transparent delivers a peak power of 435 Wp with cell efficiency of approximately 22%. The glass-glass construction (3.2+3.2 mm panes) provides exceptional durability and moisture resistance, while the transparent laminate transmits up to 40% more light than standard crystalline modules - a key advantage wherever natural light below the array matters.
Can the Solitek SOLID Solrif Transparent panels fully replace a conventional roof covering?
Yes - the SOLID Solrif Transparent is a BIPV module featuring a patented aluminum frame with an interlocking lap-joint system that forms a watertight primary roof layer, eliminating the need for a separate racking structure or underlayment. DIBt certification confirms compliance with European standards for extreme weather and snow-load resistance.
What advantage does the bifacial N-type TOPCon cell technology offer in the SOLID Solrif Transparent series?
N-type TOPCon cells achieve higher conversion efficiency and lower long-term degradation than conventional PERC cells. The bifacial design captures reflected irradiance from substrates such as carport floors or greenhouse walls, boosting annual energy yield by several percent - especially valuable on limited roof surfaces or structures with a light-colored soffit.
What warranty does Solitek provide on the SOLID Solrif Transparent, and how long does the module retain its rated power?
Solitek offers a 30-year product warranty and a 30-year linear power output warranty, guaranteeing at least 87% of the rated output after three decades of operation. This ranks among the longest warranties in the BIPV market and reflects the European manufacturing standards at Solitek's production facility in Lithuania.
Which specific applications are the Solitek SOLID Solrif Transparent panels best suited for?
The series excels wherever aesthetics and natural light transmission are priorities: terrace canopies, carports, greenhouses, pergolas, and garden pavilions. Its Fire Class A fire resistance rating permits installation on both residential and commercial buildings, while DIBt certification confirms its suitability as a stand-alone primary roof layer.
Does the Solitek SOLID Solrif Transparent carry any environmental certifications, and where is it manufactured?
Yes - the series holds the Cradle to Cradle Gold certificate, confirming production powered by 100% renewable energy and a 98% recyclability rate. Manufacturing takes place in Lithuania, EU, ensuring a short supply chain, reduced transport carbon footprint, and full compliance with stringent European production standards.
