What Solaristas, S.L. does

Solaristas, S.L. is a privately-held Spanish renewable energy engineering company headquartered in Mollet del Vallès, Catalonia, that designs, installs and maintains photovoltaic solar and aerothermia (heat pump) systems for residential, commercial and industrial customers in the Barcelona region. Founded in 2005, the company sells under a "Solaristas" trade name and positions itself on exclusive use of European/German-manufactured solar panels and on a differentiated "Vídeo Presupuesto" workflow that delivers personalized project quotations via video without requiring an initial on-site visit, complemented by in-person technical and commercial assessments.

Its service portfolio comprises four interconnected offerings: self-consumption (autoconsumo) solar projects, aerothermia installations, energy savings advisory, and a maintenance service for existing solar panel systems. Underlying technology is conventional grid-tied photovoltaic hardware combined with air-source heat pumps, sourced exclusively from German panel manufacturers and supplemented by an in-house quoting and project-explanation methodology rather than proprietary software or platform IP.

Revenue is generated on a project-by-project, quote-based professional services basis (consultation, design, installation and maintenance) with no publicly disclosed pricing. Go-to-market is sales-led and local: direct phone contact, free consultations, on-site technical/commercial visits, and the video-budget channel feed a regional Catalonia-only footprint served by a 1–10 person team with no parent company, external investors, subsidiaries or disclosed funding.
