What Alusin Solar does

Alusín Solar, S.L.U. is a Spanish privately held industrial manufacturer specializing in the design, engineering, fabrication, and installation of mounting structures for photovoltaic solar panels. Headquartered and manufactured in Avilés, Asturias, the company operates its own factory equipped with a European profile forming line, automatic saws, six hydraulic presses, vertical storage, and an in-house installation fleet including two Armivan 1200 piling machines. Its portfolio comprises six proprietary product families covering ballasted roof systems (Picos), coplanar roof systems (Gulpiyuri, Ultra Tramo G-30), driven/piled ground systems (Muniellos), concrete-footing ground systems (Cantábrico), concrete-block systems (Alublock), and specialized high-demand systems including the BULNES line for offshore floating PV. Complementary products include the CAREX® safety walkway (recognized as one of the most innovative solar PV projects of 2021 at GENERA), the Grapa Urogallo universal clamp for standing seam roofs, and the Río Sella fiber-reinforced liquid waterproofing sealant.

The company operates a hybrid revenue model: direct project sales of mounting hardware with custom quotations to EPC contractors and solar developers; project-based EPC services including structural supply, on-site piling, mechanical assembly, and panel mounting; free personalized technical-commercial advisory with delivery-timeline quotations; and sales through an authorized distributor network covering Spain (Soleme, exclusive for private/residential), Chile (Dartel), Portugal (Voltalia), and international markets (SunFields). Pricing is quote-based, includes 25-year material warranties, and incorporates concrete ballast blocks and rubber supports as standard. Customer segments span utility-scale ground-mounted developers, industrial and commercial rooftop installers, residential installers (via distribution), and self-consumption projects.

Alusín Solar maintains ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, CE marking, a French ETN certification for the PICOS family, and a verified carbon footprint, all issued by Applus+. The company is led by CEO Javier Fernández-Font and claims cumulative delivery of more than 1 GW of projects across 32+ countries on three continents, with notable installations including a 14 MW ground-mounted project (Pio Cámara, Hontoria, Spain), a 1.45 MW rooftop at the Bilbao Exhibition Centre, a 633.36 kW commercial rooftop in Tenerife (Grupo Sotecnisol), and Spain's first floating offshore photovoltaic platform (~1 MW combined, developed with BlueNewables and validated by IDONIAL). The company has received repeat regional grants from IDEPA/SEKUENS under Spain's PINT international promotion program and Cheque Tecnológico innovation subsidy, plus NextGenerationEU self-consumption incentives.

Direct peers

• STI Norland: Spanish-headquartered manufacturer of solar PV mounting structures (fixed-tilt and single-axis trackers) with global commercial reach. Directly comparable product portfolio, customer base (utility-scale developers and EPCs), and Iberian manufacturing origin to Alusín Solar.
• PV Hardware (PVH): Spanish manufacturer of fixed-tilt and single-axis solar tracking structures for utility-scale projects. Closely comparable as another Iberian PV mounting specialist competing for the same EPC and developer customers.
• Array Technologies: US-listed manufacturer of solar tracking and fixed-tilt racking systems for utility-scale solar. Comparable product category (mounting/tracking structures) and customer base (utility-scale developers and EPCs), though at materially larger scale.
• Schletter Group: German manufacturer of solar mounting systems for ground and roof applications with strong European and global presence. Comparable product families (ground-mount piling systems, ballasted and coplanar roof systems) and similar utility-scale plus commercial customer focus.
• Soltec: Spanish manufacturer of solar trackers and fixed-tilt structures serving utility-scale developers worldwide. Direct competitor in PV mounting hardware with overlapping product categories (trackers vs. fixed-tilt ground structures) and comparable Iberian manufacturing heritage.
• GameChange Solar: US-headquartered manufacturer of fixed-tilt and tracker solar racking systems for utility-scale projects globally. Comparable as a PV mounting hardware specialist competing for large-scale developer tenders, though with stronger North American footprint.
• K2 Systems: German PV mounting systems manufacturer covering rooftop, ground-mount, and carport applications. Comparable as a European mounting specialist with broad product portfolio and similar certification-driven approach to regulated markets.
• Mounting Systems: German-based manufacturer of PV mounting structures for ground and roof, owned by the Sonnedix group. Comparable product categories (fixed-tilt ground, pitched-roof, flat-roof ballasted systems) targeting utility and commercial developers in Europe and internationally.

Broad incumbents

• Nextracker: Global leader in solar tracker technology (formerly part of Flex). Competes with Alusín Solar's ground-mount portfolio for utility-scale solar tenders, but operates at vastly greater scale and is tracker-focused rather than diversified across roof/ground/offshore.
• Trina Solar (Tracker / Solar Mounting): Global module manufacturer that has expanded into solar tracker and mounting solutions. Adjacent incumbent with PV mounting offerings targeting utility-scale developers, complementary to Alusín Solar's specialist positioning in fixed-tilt and roof structures.
