Solventa6

What Solventa6 does

Solventa6 (legal entity SOLVENTA 6 SL) is a privately held Spanish engineering firm founded around 2000 and headquartered in the Girona region (Aiguaviva/Salt, Catalonia), employing between 11 and 50 people. The company provides multidisciplinary engineering, architecture, and environmental services, with its commercial centre of gravity in industrial and commercial photovoltaic self-consumption, solar parks, and battery energy storage systems (BESS), supplemented by architecture, urban planning, structural engineering, environmental consulting, and technical due diligence. All projects are executed using BIM methodology and delivered through an EPC (Engineering, Procurement, Construction) turnkey model, often incorporating fire-safety systems such as Tigo Energy's Rapid Shutdown and Huawei FusionSolar technology (the latter through a Preferred Member accreditation granted in April 2026). Solventa6 also operates a recurring maintenance subscription business (Basic, Pro, Premium tiers) and facilitates Power Purchase Agreements (PPAs), giving it a mix of one-time project fees, recurring service revenue, and third-party-financed deployments.

The company targets four primary customer segments: industrial and commercial enterprises (its primary segment), residential property owners, public institutions and government, and the agricultural sector. Distribution is conducted through direct, consultative enterprise field sales supported by a multilingual website (Catalan, Spanish, English, French) and inbound enquiry channels including phone, email, WhatsApp, and contact forms, with marketing amplified via LinkedIn, Facebook, Instagram, YouTube, and occasional trade-show participation such as Intersolar Europe 2025. Solventa6 reports cumulative figures of approximately 1,400 completed projects, 1,000 clients, 300,000 m² of projected built-up area, and 2,300 tonnes of CO₂ saved annually across its installed base, and counts among its named clients enterprises such as SEAT, Kave Home, Màgic Badalona, Friselva, Gosbi, and Agroporc. Its strategic trajectory in 2025–2026 includes international expansion (Hungary), development of its own 1 MWp solar park in Girona, and recognition through the BBVA E-TECH sustainability award.

Revenue model

1. EPC Project Delivery: Turnkey engineering, procurement and construction contracts for photovoltaic installations, covering design, installation, commissioning, legalisation, and maintenance. Revenue is generated through one-time project fees for the full project lifecycle from concept to delivery.
2. Maintenance Contracts: Recurring maintenance contracts for solar installations offered in three tiers (Basic, Pro, Premium). Revenue is recurring and predictable, with plans covering annual inspections, panel cleaning, performance reporting, predictive maintenance, and 24/7 assistance.
3. PPA (Power Purchase Agreements): Long-term energy purchase agreements where Solventa6 facilitates solar installations owned by a third party on the customer's site. Revenue is generated through facilitating and managing the PPA arrangement, with customers paying for energy consumed at a fixed competitive rate.
4. Architecture and Engineering Services: Fees for architectural design, structural calculation, construction management, and urban planning services. Projects include residential buildings, commercial buildings, hotels, industrial facilities, and public sector works.
5. Technical Due Diligence: Independent technical audit services for property acquisition, renovation, or investment decisions. Includes on-site inspection, documentary analysis, and detailed report with CAPEX estimates.

Direct peers

• Solarpack (now Statkraft): Spanish utility-scale solar PV developer and EPC contractor headquartered in the Basque Country. Directly comparable to Solventa6 in core solar EPC delivery, though operating at much larger MW-scale and with IPP ownership model. Was acquired by Statkraft in 2024.
• Grenergy Renovables: Madrid-listed Spanish renewable energy developer focused on solar PV and BESS storage, operating across Latin America and Europe. Compares to Solventa6 on solar + storage IPP/PPA model and industrial self-consumption segment, though at far greater scale.
• Solaria Energía y Medio Ambiente: Spanish solar PV company listed on the Madrid continuous market, focused on rooftop and utility-scale PV with vertical integration into development and EPC. Highly comparable to Solventa6's solar PV and BESS focus.
• Cox Energy (now Coxabengoa): Spanish solar PV developer and EPC focused on Latin America and Iberia; recently merged with Abengoa's energy unit. A more direct solar PV peer to Solventa6 than the diversified majors, with similar mid-size project DNA.
• Audax Renovables: Spanish renewable energy and retail electricity operator with solar PV generation portfolio across Iberia. Compares with Solventa6 on solar generation / PPA channel and Spanish market focus, though operates primarily through generation rather than turnkey EPC.
• Insolit Energia: Catalan solar PV EPC and engineering firm focused on industrial and commercial self-consumption across Catalonia. Highly comparable to Solventa6 on regional focus, customer profile (SME industrial), and self-consumption value proposition — and the most directly competitive peer in Solventa6's home geography.

Broad incumbents

• TSK Energía y Soluciones Industriales: Large Spanish industrial EPC firm delivering solar PV, BoP, and energy infrastructure projects worldwide. Operates in the same solar EPC category as Solventa6 but at much larger industrial scale with broader geographic presence.
• Acciona Energía: Spanish Ibex-35 listed renewable energy major with global solar PV and wind IPP operations. Overlaps with Solventa6 in solar project development and EPC services, but as a much larger diversified portfolio player rather than a regional specialist.
• IDOM: Large Spanish engineering and architecture consulting firm with renewable energy practice. Comparable to Solventa6's engineering/architecture/environment services overlay, but at much greater scale and global footprint.
• Sener Grupo de Ingeniería: Spanish engineering group with EPC capabilities in solar PV and renewable energy infrastructure. Similar engineering + EPC + renewables combination to Solventa6, but with much broader industrial and aerospace portfolio.
