Sunfer - an Enstall brand

What Sunfer - an Enstall brand does

Sunfer Estructuras S.L. (operating as Sunfer Energy and branded as 'Sunfer – an Enstall brand') is a Spanish manufacturer of aluminum mounting structures for photovoltaic solar panels, founded in 1999 and headquartered in Albalat de la Ribera, Valencia. The company designs, engineers, and manufactures a comprehensive product portfolio that includes coplanar systems for tiled, metal, and lightweight roofs; inclined/tilted supports; ballasted systems; concrete foundations (in development); facade mounts; ground/terrain mounts; carport/canopy structures; and micro-rails. All production is concentrated at a 30,000 m² vertically integrated facility in Valencia, where Sunfer controls the full value chain from design and engineering through aluminum profile fabrication (EN AW-6005A T6 alloy) to pre-assembly of finished kits, with stated capacity of more than 3,000 kits per day and a permanent stock of 14,000+ ready-to-ship kits backed by 170 MW+ of raw material inventory. The company uses 90% recycled aluminum in production and holds ISO 9001:2015, ISO 14001:2015, CE marking, and UNE-EN 1090 certifications.

Sunfer generates revenue through hardware sales of pre-assembled mounting kits (for residential and self-consumption installations) and bulk material formats (for commercial, industrial, and utility-scale projects), complemented by a full range of accessories. Pricing is quote-based and project-specific with no public list pricing, and warranties extend up to 25 years. The go-to-market is hybrid: direct enterprise sales for large projects (exemplified by airport, oil and gas, and rural electrification deployments) alongside a distributor network serving 30+ countries, with dedicated Iberia and Latam solution tracks. Supporting the sales motion are digital tools (SunferKey 2.0, Sunfer Selector, SunferProject) and an installer training program. Customer segments span residential self-consumption, commercial and industrial rooftop and ground-mount, and regional distributors. Since 2024, Sunfer has operated as a wholly-owned subsidiary of Enstall, a Netherlands-based European solar mounting systems group that also owns PanelClaw and Esdec.
