What Dimas does
Dimas SA (legal name: DIMAS A.E.V.E.; trade name Dimas Solar) is a Greek designer and manufacturer of solar thermal energy systems, headquartered in Argos, Argolida Prefecture, and active internationally across 65 markets. Founded in 1979 by Konstantinos and Evangelos Dimas and now led by CEO Tassos Dimas, the company operates as a family-owned B2B enterprise with six production plants totaling roughly 92,000 m2 and a headcount of 51–100 employees. Solrico ranked it the 2nd-largest solar collector manufacturer in Europe and 7th worldwide in 2023.
The product portfolio is vertically integrated and covers flat-plate solar collectors (Supreme, Navi+ Evo, Sol+ Evo, Terra+ Evo, Energy+ Evo/Argo/Eco), complete thermosiphon solar water heating systems (Thermo+ Flat/Universal/TSS/Eco), storage tanks (Hydro+ Evo/Inox/Eco from 120L–500L), mounting structures (Neo+ Universal/Flat/TSS/Low/Eco/Col), OEM absorbers (Hyflo+, Grill+, Fin+), and connection/accessory kits. Manufacturing relies on Fiber LASER Welding (first deployed in Greece in 2000), robotic unibody assembly lines, ecological-enamel tank protection, and an Online Production Monitoring system. Multiple international certifications (Solar Keymark, SRCC, SASO, DCL, ISO 9001 by DEKRA, Energy Star, EBHE) underpin regulatory access across export markets.
Dimas generates revenue exclusively through B2B channels. There are three revenue streams: (1) branded solar collector and system sales to distribution partners; (2) OEM / white-label manufacturing where customers rebrand Dimas-made collectors, tanks, and absorbers under their own labels with Dimas quality warranties; and (3) participation in domestic government subsidy programs such as the Greek 'Allazo' energy-efficiency scheme. Pricing is not publicly disclosed; orders are managed through a dedicated B2B portal that delivers real-time pricing, order status, shipment tracking, and technical documentation. Customer acquisition is concentrated at major international trade shows (ISH Frankfurt, Big 5 Dubai/Saudi/Egypt, Interclima Paris). Average operational scale is approximately 650 active customers, 3,500 orders, and 3,900 receipts/dispatches per year, with a 97% On-Time-In-Full delivery rate.
