Ertex Solar

What Ertex Solar does

Ertex Solar (legal entity: ertex solartechnik GmbH) is an Austrian building-integrated photovoltaics (BIPV) manufacturer founded in 2004 and headquartered in Amstetten, Austria. The company designs and produces glass-integrated photovoltaic modules that transform building envelopes — façades, balconies, canopies, and roofs — into active, energy-generating surfaces. Its portfolio spans five core product lines — Balcony Railings, Insulating Façades, Ventilated Façades, Canopies, and Insulating Roofs — built on VSG (laminated safety), ESG (tempered), and TVG (toughened float) glass variants with transparency levels ranging from 0% to 55%, and offered in design-color, screen-printed, and full-black aesthetic configurations including XXL format modules.

The company sells BIPV hardware primarily through a direct sales model combined with a regional partner and installer network covering Germany, Austria, Switzerland, Greece, Cyprus, Malta, and the Scandinavia/Baltic region. Pricing is not publicly disclosed; customer engagement runs through project-based website inquiries and named reference projects. The customer mix spans residential, commercial, and institutional segments, with named enterprise references including the Audi Brand Experience Center (Munich), Fronius, Zotter Schokolade, Tiergarten Schönbrunn, Utrecht Centraal Station, Campus TUM, Tiroler Versicherung, and Gare de Namur. Ertex holds ISO 9001, ISO 14001, and ISO 13485 (Kiwa 61215:61730) certifications plus a DIBt general building authority approval (abZ) for the German market.

Ertex Solar operates as a subsidiary within the Soletanche Freyssinet group, ultimately owned by French construction conglomerate VINCI. The company states 70 years of combined glass-construction experience within its specialist team, claims buildings using its solutions can cover up to 100% of electricity needs via local generation while reducing air conditioning and lighting loads by 20–30%, and has received industry recognition including a 2024 Architekturpreis Gebäudeintegrierte Solartechnik podium placement, the 2021 Construction21 Green Solutions Award User's Choice, and the 2020 Austrian InnovationsAward BIPV-Award.

Core offering

Ertex Solar produces and distributes building-integrated photovoltaic (BIPV) modules that replace conventional building envelope materials. Their portfolio spans five core product lines — balcony railings, insulating façades, ventilated façades, canopies, and insulating roofs — manufactured in Austria and sold across Europe via certified installer partners. The company combines expertise in photovoltaics and glass construction to deliver customisable, semi-transparent, and full-black solar glass modules with VSG, ESG, and TVG glass variants.

Product overview

Ertex Solar is a building-integrated photovoltaics (BIPV) specialist offering a unified portfolio of five core product lines: Balcony Railings, Insulating Façades, Ventilated Façades, Canopies, and Insulating Roofs. All products integrate photovoltaic technology directly into building envelope elements, transforming traditional building components into active energy-generating surfaces. The company combines expertise in photovoltaics and glass construction (70 years of combined experience) to deliver aesthetically integrated solar solutions without compromising architectural design. The product architecture follows a modular approach where each category offers various glazing options (VSG, ESG), transparency levels, and customization options including full-black, semi-transparent, and design-color variants.

Scale indicators3 records

Recent moves5 records

Expansion highlights5 records

Direct peers

• Sunovation: German BIPV module manufacturer producing glass-glass photovoltaic modules for façades, roofs, and balustrades. Closest direct competitor to Ertex in DACH region with similar customization, transparency, and color offerings targeting architectural integration.
• Onyx Solar: Spanish manufacturer of photovoltaic glass for building integration (façades, skylights, curtain walls). Closely comparable to Ertex in product architecture and customization, though primarily serving Southern European and international markets.
• Avancis: German CIGS thin-film BIPV module producer, owned by CNBM. Produces building-integrated solar modules for façades and rooftops, competing directly with Ertex in the European architectural-grade BIPV segment with a different cell technology.
• Polysolar: UK-based BIPV company producing transparent and opaque photovoltaic glazing for façades, roofs, and canopies. Directly comparable to Ertex in product mix and architectural integration focus, serving UK and European building-integrated solar markets.
• ClearVue Technologies: Australian BIPV glazing company producing semi-transparent photovoltaic glass for façades and windows. Comparable to Ertex in BIPV product category and architectural integration, though serving primarily Asia-Pacific and select international markets.
• Solibra: Czech BIPV module manufacturer specializing in building-integrated photovoltaic solutions for façades and roofs. Comparable to Ertex in European BIPV niche with similar glass-integrated product architecture.
• Apollon Solar: French BIPV specialist manufacturing photovoltaic glass modules for building façades, canopies, and rooftop integration. Comparable to Ertex in the European BIPV niche with similar aesthetic-integration value proposition.

Emerging players

• BIPVco: UK-based BIPV company producing lightweight photovoltaic building products for façade, roof, and shading applications. Comparable to Ertex in BIPV focus and architectural integration, though typically serving earlier-stage and emerging-market deployments.
• Heliatek: German organic photovoltaic (OPV) film company developing ultra-thin flexible solar films for building façades and windows. Adjacent to Ertex in BIPV application space but using a fundamentally different (organic) cell technology targeting surface-applied rather than glass-integrated solutions.

Broad incumbents

• Tesla (Solar Roof): Tesla's Solar Roof offers aesthetically-integrated photovoltaic roofing tiles in the residential and light-commercial segment. A broader incumbent in solar roofing/BIPV with vastly greater scale, brand recognition, and balance sheet than Ertex, though with less architectural customization depth.
