Core offering

Endurans Solar manufactures and sells co-extruded polyolefin-based backsheets (ENDURANS® HP series, including D15, D15BE, D15HRB, and D15T variants) and encapsulant films (ENDURANS® ME multi-layer and ENDURANS® SE single-layer EVA/POE) for photovoltaic module producers. Products are sold directly to solar panel manufacturers worldwide, with U.S. domestic manufacturing in Nashua, New Hampshire. The portfolio emphasizes hydrolytically stable, PFAS-free, fully recyclable, and IRA/FEOC-compliant materials designed to extend PV module lifetime and reduce the cost of solar energy.

Product overview

Endurans Solar is a leading U.S.-based manufacturer of innovative materials for the photovoltaic industry, producing a portfolio of three core product lines: ENDURANS® HP (co-extruded polyolefin backsheets), ENDURANS® ME (multi-layer encapsulants), and ENDURANS® SE (single-layer encapsulants). The HP series includes four backsheet variants (D15, D15BE, D15HRB, D15T) serving mono-facial, all-black residential, high-efficiency residential, and bifacial module applications respectively. The ME series features EPE encapsulant with unique high moisture barrier technology. The SE series offers EVA and POE encapsulant options for various cell types including PERC, TopCon, and HJT. All products are American-made, FEOC-compliant, and designed for sustainability with full recyclability.

Direct peers

• Cybrid Technologies: One of the largest Chinese manufacturers of PV backsheets and encapsulants, offering TPT/TPE backsheets and EVA/POE encapsulants. Cybrid competes directly with Endurans in supplying module manufacturers globally and represents the primary cost-based competitive threat in the backsheet market.
• Hangzhou First PV Material: Major Chinese PV backsheet and encapsulant manufacturer (First PV) producing fluorinated and non-fluorinated backsheets plus EVA encapsulant films. Direct head-to-head competitor with Endurans for module manufacturer contracts across all major cell technologies.
• Krempel GmbH: German manufacturer of high-performance backsheets for the PV industry with a focus on European markets and premium applications. Comparable to Endurans in product positioning around durability and quality, serving similar European and US module manufacturer customers.
• Coveme: Italian manufacturer of specialty backsheets and encapsulant films for photovoltaic modules, with established positions in European PV supply chains. Comparable to Endurans in engineered polyolefin backsheet technology and European customer base overlap.
• Jolywood: Chinese PV materials company specializing in backsheets (including fluorinated-free options) and n-type cell encapsulation solutions. Direct competitor with overlapping product portfolio in both backsheets and encapsulants.
• Dunmore: US-based manufacturer of specialty films and laminates including backsheet substrates for PV modules. Comparable to Endurans as a US-domiciled backsheet supplier serving the domestic module manufacturing market under IRA-compliant frameworks.

Broad incumbents

• Borealis: Major polyolefin producer (part of OMV) supplying encapsulation-grade polymers (EVA, POE, EPE) to the PV industry. While not a direct backsheet manufacturer, Borealis competes with Endurans in encapsulant material supply and represents a much larger, established alternative for module manufacturers.
• Mitsui Chemicals: Japanese chemical company with significant PV encapsulant (EVA) and backsheet raw material production. Competes with Endurans as a broader materials incumbent serving module manufacturers with diversified film and chemical offerings.
• Celanese: Global chemical company producing EVA-based encapsulant films (through its engineered materials business) and other PV-relevant polymers. A broader incumbent competitor to Endurans in encapsulant supply, leveraging much larger scale and R&D resources.

Emerging players

• Targray: Distributor and emerging supplier of PV materials including backsheets, encapsulants, and front-side materials to module manufacturers. Comparable to Endurans in serving the same customer base with adjacent materials products, though primarily through distribution rather than manufacturing.
