Biosphere Solar

What Biosphere Solar does

Biosphere Solar is a Netherlands-based solar technology company, spun out of TU Delft, that develops and sells lamination-free, fully dis-assemblable PV modules under the ReModule brand. Its core technology replaces conventional EVA lamination with a Poly-Iso-Butylene edge-seal encapsulation, enabling repair, refurbishment, upgrade, and high-value recycling at end-of-life — capabilities the company claims laminated panels cannot offer. The current product line includes the ReModule 1-108 (430 Wp, 108-cell TOPCon bifacial, rooftop-optimized) and ReModule 1-120 (480 Wp, 120-cell TOPCon, utility/commercial), plus European-made Custom Modules with ColorBlast aesthetic printing. IEC 61215 and IEC 61730 certifications for the v1.4 generation are targeted for Q1 2026.

The company operates a three-stream revenue model: B2B hardware sales of ReModule modules via a quote-based, European-focused sales motion; licensing of its lamination-free ReModule manufacturing technology to existing solar producers (named partners Soltech, Kameleon Solar, Einnova); and consultancy services advising energy companies and solar park constructors on circular value-chain transitions. Pricing is positioned at "Tier I module pricing" with no public list. Manufacturing is distributed across three production sites — China for standard 108/120-cell modules and Europe for custom designs — with a pilot production line additionally established at Blue City Rotterdam, where the company relocated from Delft in 2024.

Biosphere's capital base is unusually non-dilutive: rather than venture capital, the company has accumulated roughly €12.3M in EU and Dutch public grants across RVO (FAIR PV), Interreg (Independent PV, PV Resilience), Op-Zuid (Circular Multicolour Gevel PV-Fabriek), Horizon Europe (Solar-SOPHIA), and the Municipality of Rotterdam. The company operates under a steward-ownership model and publishes hardware designs under the CERN-OHL-S open-source license, with a global contributor community on Discord and Wikifactory. Customer evidence to date is concentrated in pilot and research deployments — AMS Institute (2 panels), Beach Grid Scheveningen (10 panels), Green Village Delft (27 panels), and the Municipality of Den Haag — alongside a still-pending IEC certification as the gating milestone for broad commercial scale-up.

Core offering

Biosphere Solar manufactures and sells circular, fully dis-assemblable photovoltaic modules under the ReModule brand, replacing conventional EVA lamination with edge-sealing to enable repair, refurbishment, and high-value recycling. It offers three standard SKUs — ReModule 1-108 (430 Wp, rooftop), ReModule 1-120 (480 Wp, utility), and custom modules for architectural/BIPV projects — at Tier-1 pricing with a 10-year product warranty and 30-year power warranty. In parallel, the company licenses its lamination-free encapsulation process to solar manufacturers and provides consultancy services for circular value-chain transition.

Product overview

Biosphere Solar offers a portfolio of circular, lamination-free, fully dis-assemblable PV modules sold under the ReModule brand. The core product line includes the ReModule 1-108 (430 Wp, 108-cell, rooftop-optimized) and ReModule 1-120 (480 Wp, 120-cell, utility-scale), both featuring TOPCon technology, up to 50% lower carbon intensity, and <0.3% annual degradation.

Scale indicators5 records

Recent moves8 records

Expansion highlights7 records

Direct peers

• Soltech: Belgium-based solar manufacturer and Biosphere Solar's industrial partner for the Independent PV Interreg project. Comparable because it integrates ReModule technology into its own production line to manufacture circular PV modules — making it both a licensee and a direct producer of competing circular modules.
• Kameleon Solar: Dutch solar manufacturer producing aesthetic, building-integrated PV panels using ReModule encapsulation under the Circular Multicolour Gevel PV-Fabriek project. Directly comparable because it commercializes circular PV using Biosphere's licensed technology for facade and BIPV applications.

Broad incumbents

• Meyer Burger Technology: European premium PV module manufacturer with cell-to-module production in Germany. Comparable because it represents the established European alternative to Asian Tier-1 solar manufacturing and competes in the same high-quality, EU-sourced PV market segment Biosphere targets.
• First Solar: US-headquartered thin-film PV module manufacturer with strong ESG/sustainability positioning and large utility-scale footprint. Comparable because it represents an incumbent alternative to crystalline silicon modules and has invested in circularity / recycling initiatives, making it a long-term competitor as the circular PV segment grows.
• SunPower (Maxeon): Premium residential and commercial solar module brand with high-efficiency cells and long warranties. Comparable because it competes for the same premium residential rooftop segment as ReModule 1-108 and similarly emphasizes durability and warranty differentiation.

Emerging players

• SolarCycle: US-based solar panel recycling and circularity startup. Comparable because it operates on the same end-of-life / circular solar thesis as Biosphere, addressing the recycling problem from the downstream side rather than the panel-architecture side.
• ROSI Solar: French startup focused on high-value recovery of silver and other critical materials from end-of-life PV panels. Comparable because it tackles the same PV waste circularity problem Biosphere's modular design addresses, though from a recycling-process rather than module-design perspective.
• Oxford PV: UK/Germany-based perovskite-silicon tandem PV developer focused on next-generation cell technology. Comparable because it represents the European deep-tech PV innovation ecosystem and pursues performance + sustainability premium positioning similar to Biosphere's circularity angle.
• SunRoof: Swedish BIPV / solar roof manufacturer producing integrated roof-mounted solar systems. Comparable because it operates in the aesthetic BIPV / custom module space that Biosphere's Custom Modules and ColorBlast products target, serving architects and developers of innovative building projects.

Regional players

• Energetica Industries: Austrian-European premium PV module manufacturer. Comparable because it competes for the European high-quality residential and commercial segment with similar Tier-1 positioning and Austrian/German manufacturing heritage analogous to Biosphere's European production narrative.
