What CSolar does

CSolar (legal entity CERO METROS INGENIERÍA S.L.) is a Spanish private engineering and manufacturing firm that designs, fabricates, and supplies certified structural support systems for photovoltaic installations. Founded in 2012 and headquartered in Ripollet, Barcelona, the company produces aluminum and stainless steel mounting structures covering essentially every PV deployment surface: flat-roof ballasted (CS-FLAT), self-supporting aerodynamic flat-roof (CS-WIND), inclined concrete-roof (CSI), coplanar sloped-roof (CSA), ground-mount utility-scale (CS-LAND), building-integrated façades (CS-WALL), plus architectural products such as CS-PERGOLA and CS-CARPORT. All systems are engineered and certified to the Spanish Building Technical Code (CTE) and European structural Eurocodes for wind, snow, and seismic loads, and are backed by a 25-year warranty.

The company's revenue model is a mix of hardware sales (proprietary mounting structures and components) and professional services (structural engineering, on-site installation, and structural verification reports/certifications). Pricing is quote-based and not publicly disclosed; sales run through a direct enterprise field motion targeting EPCs, solar installers, engineering firms, and energy developers, with regional manufacturing and distribution in Spain (Ripollet), Argentina (Mendoza), and Chile (Santiago), and active sales reach into Colombia. The customer base spans retail (IKEA Jerez and Valls, BonpreuEsclat), food processing (Casa Tarradellas), healthcare (Sanitas), automotive (BMW), government (Artés Town Hall), and education (Campus Mundet / Universitat de Barcelona).

Operationally, CSolar is a small firm (11-50 employees) competing in the European PV mounting hardware market, where it differentiates through in-house manufacturing, certified engineering, and a comprehensive proprietary product portfolio. The business is privately held with no external funding rounds disclosed, and the founder and CEO is Manuel Sánchez Blanco. Strategic emphasis appears to be on multi-vertical European and LATAM expansion, BIPV/architectural integration product extensions, and tier-one enterprise customer acquisition rather than AI or software differentiation.
