SOLRIF D Semi-Clear solar panels from SoliTek are a solution specifically designed for integrated roof installations while maintaining partial light transmission. By using dual-sided N-type TOPCon cells, the modules generate energy from both the front and back sides, increasing energy yield in varying lighting conditions. The glass-glass construction with tempered glass provides exceptional durability and resistance to weather conditions - rain, snow, hail - with an estimated lifespan of up to 50 years. SOLRIF D Semi-Clear is suitable for any location where both natural lighting and energy production are needed: carports, pergolas, terraces, awnings, and illuminated roofs. The mounting system, similar to that used for tiles, allows the module to be integrated onto the roof at an angle from 12 to 70 degrees, eliminating the need for a separate roof covering layer. The panels have a DIBt certification, confirming their suitability for high-load applications and use in living spaces. Manufactured in Europe with 35% recycled glass content and using renewable energy, they meet the requirements of the Cradle-to-Cradle Gold certification - making them a choice for investors who value both efficiency and environmental responsibility.

About the SOLRIF D Semi-Clear series

6 answered

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

Can SOLRIF D Semi-Clear panels replace traditional roofing material without an additional waterproofing layer?
Yes. SOLRIF D Semi-Clear is a BIPV system mounted directly on battens, just like roof tiles, and the modules themselves form a weatherproof roof covering. The patented interlocking aluminum frame creates a watertight seal between panels, eliminating the need for a separate membrane or tiles. The system is engineered for pitched roofs with slopes between 12 and 70 degrees, covering the vast majority of residential and commercial roof types.
What warranty does SoliTek offer on the SOLRIF D Semi-Clear panels?
SoliTek provides a 30-year product warranty and a 30-year power warranty, guaranteeing at least 90% of the rated 455 Wp output throughout that period. This exceeds standard industry terms and is backed by the glass-glass construction using 3.2 mm tempered glass on both sides, with an estimated module service life of up to 50 years.
How much light do SOLRIF D Semi-Clear panels transmit, and are they suitable for carport or pergola roofing?
The panels transmit up to approximately 40% of daylight, creating a semi-transparent glazing effect. This makes them an excellent choice for carports, pergolas, terraces, and covered walkways where natural illumination of the space below is as important as energy generation. The DIBt certificate specifically approves the panels for use above occupied spaces, a requirement under many local building codes.
How does the bifacial TOPCon cell technology in SOLRIF D Semi-Clear work, and what practical benefit does it offer?
The N-type TOPCon cells are bifacial, harvesting energy from both the front side and the rear side of the panel. The rear glass transmits diffuse light reflected from ground surfaces or the sky, boosting energy yield by up to several percentage points compared to monofacial modules. The temperature coefficient of Pmax is only -0.30%/°C, meaning the panel outperforms older PERC cells on hot days.
Are SOLRIF D Semi-Clear panels environmentally certified, and do they qualify for green procurement criteria?
Yes. The panels are manufactured in Lithuania using renewable energy, and the glass contains 35% recycled content. SoliTek holds the Cradle-to-Cradle Gold certification, which evaluates the product across its full lifecycle and circular economy metrics. This is one of the highest-tier environmental certificates recognized in construction and PV procurement, including public tenders requiring EPD or LCA documentation.
How heavy are SOLRIF D Semi-Clear panels, and can a standard roof or pergola structure support them?
The 455 Wp variant weighs approximately 35 kg with dimensions of 1806×1160×20 mm, resulting in a surface load similar to heavy ceramic roof tiles. The glass-glass construction with dual 3.2 mm tempered panes is rated for high snow and wind loads. For pergola or retrofit roof installations, a structural engineer should assess the load-bearing capacity before installation.
