Isola Solar AS

What Isola Solar AS does

Isola Solar AS is a Norwegian private company, founded in 2020 and headquartered in Larvik, Norway, that designs, supplies, and installs bifacial solar panel systems for commercial and industrial buildings with flat roofs. The company is jointly owned by Isola Holding (66%) and Skagerak Energipartner (34%), inheriting 80+ years of roofing expertise from the Isola Group. Its two core product lines are the Bifacial solcellesystem—a tilted aluminum mounting system that captures solar irradiation from both panel sides, leveraging albedo from reflective roof membranes or snow—and Bygningsintegrert (BIPV), where solar panels replace conventional roofing materials.

The technical platform centers on bifacial panels mounted at approximately 35 degrees with 60-70 cm clearance to the roof membrane, anchored via patented base fasteners that distribute weight into the building's load-bearing structure. This configuration is SINTEF-tested for wind resistance and designed to allow roof membrane replacement without dismantling the solar array. The company reports up to 67% higher energy yield versus monofacial panels in Nordic conditions and production ratios of 1,153-1,311 kWh/kWp/year at reference installations. Partnerships extend the platform into battery storage and AI-driven energy management via the E-Tak concept (Lett-Tak) and virtual power plant services (TGN Energy, Hitachi Energy).

Isola Solar operates a direct enterprise sales model targeting commercial and industrial building owners, primarily in Eastern Norway. All sales involve site assessment and bespoke project quotations; there is no public pricing or self-serve channel. Revenue derives from project-based system sales and installation, supplemented by Enova subsidy application writing, roof rehabilitation-plus-solar integration services, and the emerging E-Tak storage-plus-AI offering. The customer base includes retail parks (Langronningen 854 kWp, Skeidar Menstad 935 kWp), manufacturers (Kingspan, Revac), district heating operators, and real estate developers, with 10+ bifacial and 3 BIPV projects completed since founding.

Core offering

Isola Solar AS designs, supplies, and installs bifacial solar panel systems and building-integrated photovoltaic (BIPV) solutions for commercial and industrial buildings with flat roofs in Norway. The company sells complete engineered systems — including proprietary aluminum mounting structures with patented base fasteners, bifacial panels tilted at approximately 35 degrees, and high-albedo roof membrane integration — and provides roof assessment, energy analysis, project planning, Enova subsidy application writing, and after-sales support. Two core product lines are offered: the Bifacial solcellesystem (roof-mounted tilted panels) and Bygningsintegrert (BIPV) systems where panels replace roofing materials.

Product overview

Isola Solar AS offers two main product lines: the Bifacial solcellesystem and Bygningsintegrert (BIPV). The Bifacial system is a roof-mounted, tilted solar panel solution that captures sunlight from both sides, designed specifically for flat Norwegian commercial and industrial roofs. The BIPV product integrates solar generation directly into the building structure. Both products emphasize the company's 80-year heritage in roofing expertise, with the solar systems designed to work in harmony with the building's roof membrane, structural integrity, and maintenance needs rather than being treated as add-on equipment.

Products and services

• Bifacial solcellesystem (Bifacial Solar Panel System) A complete bifacial solar panel system for flat commercial and industrial roofs in Nordic climates. Panels are mounted in fixed aluminum structures at approximately 35-degree angles, 60-70 cm above the roof membrane, capturing direct sunlight on the front and reflected light (albedo effect) from reflective roofing membranes or snow on the rear. Anchored directly into the building's load-bearing structure using patented base fasteners that are SINTEF-tested and certified for hurricane-force wind loads and roof membrane integrity. Specifications include up to 67% higher energy production than monofacial panels, 2% snow-related downtime vs 16% for monofacial, and production ratios of 1,153 to 1,311 kWh/kWp/year. Designed for commercial building owners with 1,000-2,000+ m² flat roofs.
• Bygningsintegrert (BIPV) System Building-integrated photovoltaic (BIPV) solutions where solar panels replace or integrate with traditional roofing materials, providing both energy generation and building envelope functionality on the building's own terms. Available for new construction and major roof renovation projects, with reference projects ranging from 21 kWp (Borgetun, Skien) to 115 kWp (Låve at Årnes). Designed for commercial, residential, district heating, and agricultural building owners who want solar generation integrated into the building fabric rather than as roof-mounted equipment.
• E-Tak Concept (Solar + Battery + AI Power Management) Combined solar and battery solution with AI-driven smart power management, developed in partnership with Lett-Tak. Integrates Isola Solar bifacial panels, Lett-Tak roof elements, and battery storage with intelligent energy management. Designed for commercial and industrial building owners who want integrated roof, solar, and energy storage with smart power management. First commercial deployment at Lett-Tak facility in Larvik at 51 kWp.
• Roof Rehabilitation + Solar Integration Service Combined roof rehabilitation and solar panel installation service, integrating roof membrane replacement with solar system deployment in a single project. Delivered in partnership with roofing partner BVT Hesselberg Tak. Designed for commercial building owners undertaking major roof renovation who want to deploy solar simultaneously. Demonstration project at Fargerike C. Christoffersen AS in Skien deployed 268 kWp across three different roof types (gray PVC, white reflective membrane, and sedum green roof).
