The SOLRIF D Terracotta Bronze series from SoliTek is a solution designed for integrating photovoltaic systems with historic and urban architectural structures.

BIPV modules installed like tiles create a seamless, uniform roof surface - the panels become an integral part of the roofing, rather than a visible addition. Thanks to specially treated glass that reduces light reflection and glare, the installation from the street looks like matte ceramic, which is crucial for meeting strict conservation and architectural requirements.

Double-strength glass construction provides exceptional resistance to extreme weather conditions - the modules meet the highest hail resistance class and can withstand very heavy loads from snow and wind. The flexible mounting angle range (from 12 to 70 degrees) offers a wide range of design possibilities on various roofs. This is the ideal choice for investors undertaking installations in conservation areas, historic cities, and buildings subject to architectural regulations, where standard panels are not permitted.

Cradle to Cradle Gold certification and 30-year product and performance warranty confirm the highest quality standard - the modules are manufactured in Europe using renewable energy.

Common questions

6 answered
Can SOLRIF D Terracotta Bronze panels be installed on heritage or conservation-protected buildings?
Yes, SoliTek's SOLRIF D Terracotta Bronze series was specifically designed for listed buildings and conservation zones. The specially treated anti-reflective glass makes the installation look like matte ceramic from street level rather than conventional PV panels. The modules integrate into the roof like traditional tiles, forming a sealed, uniform surface that enables compliance with strict architectural and heritage preservation requirements.
What mounting angle range does the SoliTek SOLRIF D Terracotta Bronze support?
The SOLRIF D Terracotta Bronze series supports mounting angles from 12 to 70 degrees, offering broad design flexibility. This range makes the modules suitable for both low-pitch roofs and steep pitches typical of historic urban buildings. The wide angular range is a significant advantage for BIPV installations on architecturally complex or non-standard structures.
What warranty does SoliTek offer on the SOLRIF D Terracotta Bronze series?
SoliTek provides a 30-year product warranty and a 30-year power output warranty on the SOLRIF D Terracotta Bronze series. This is among the longest warranty periods available on the market and reflects the high manufacturing standards of European production powered by renewable energy. The modules also carry Cradle to Cradle Gold certification, confirming responsible and sustainable manufacturing practices.
What is TOPCon technology and why is it used in the SOLRIF D Terracotta Bronze series?
TOPCon (Tunnel Oxide Passivated Contact) is an advanced cell technology that achieves higher efficiency than standard PERC cells, typically exceeding 22%. In the SOLRIF D Terracotta Bronze series, TOPCon enables a maximum output of 370 Wp within a compact BIPV module format. Higher cell efficiency is especially valuable in BIPV applications where available roof area is constrained by the building's architecture and heritage requirements.
Are SOLRIF D Terracotta Bronze modules bifacial, and how does that benefit a rooftop BIPV installation?
Yes, the SOLRIF D Terracotta Bronze series features bifacial cells capable of generating power from both the front and rear surfaces. In BIPV roof installations, the rear side can capture diffuse and reflected irradiance from the mounting substructure, increasing overall energy yield. The dual tempered glass construction simultaneously serves a protective and aesthetic function, replacing conventional roofing material entirely.
How do SOLRIF D Terracotta Bronze panels handle extreme snow loads and hail?
The SOLRIF D Terracotta Bronze series offers exceptional mechanical resilience. Its dual tempered glass construction provides the highest hail resistance rating and is capable of withstanding very high snow and wind loads. This is a critical parameter for rooftop installations on historic buildings in climates with harsh winters, where structural integrity must satisfy both safety standards and conservation authority requirements.
