What Sater-solar does

Sater Solar (SA.T.E.R-SOLAR) is a Tunisian photovoltaic engineering, procurement, and construction (EPC) company founded in 2007 in Sfax by the SIALA and MASMOUDI families, with a secondary office in Tunis and approximately 40 employees. The company designs, installs, commissions, and maintains grid-connected and off-grid solar power systems for residential, commercial, industrial, and agricultural/rural electrification customers, operating across project scales from small residential installations (10-17 kWc) up to utility-scale power plants (1 MWc and above, with a 10 MWp pipeline in 2022). To date the company reports more than 1,524 completed installations totaling over 15 MWc of installed capacity, supported by ISO 9001/14001/45001 certifications and technology and commercial partnerships with KACO New Energy and Sofia Holding.

Revenue is generated primarily through project-based turnkey EPC contracts for solar power systems, supplemented by real-time monitoring services and after-sales maintenance. The customer mix is diversified by segment but anchored by enterprise and institutional accounts including Ola Energy, Total Energy, AGIL-GAZ, SORIMEX, ISA, Société Hlouwa, MEDREC, and SONEDE. The business model is sales-led and execution-driven: the company secures tenders or direct commercial contracts, supplies panels, inverters, and balance-of-system components through its partnerships, and delivers installed systems under fixed-price project terms. Notable marquee projects include the 1 MWp MATMATA ground-mounted power plant and a 503 KWc installation for MEDREC/SONEDE, signaling an operational pivot toward larger-scale EPC work alongside the legacy distributed-installation base.

Broad incumbents

• Voltalia: France-headquartered renewable energy IPP and EPC operator with a global utility-scale and distributed solar portfolio. Voltalia competes with Sater-solar at the utility-scale end of the market (multi-MWc PV plants, EPC services) but operates at much larger scale across multiple continents.
• Scatec ASA:

Direct peers

• Phanes Group: Dubai-based solar developer focused on C&I and utility-scale PV projects across MENA and emerging markets. Phanes Group operates with a similar asset-light EPC-plus-IPP model targeting commercial and industrial off-takers in regions where Sater-solar is active, making it a strong regional peer.
• Yellow Door Energy: UAE-headquartered C&I and utility-scale solar EPC and IPP serving MENA. Yellow Door Energy operates a comparable distributed-to-utility-scale solar business model in the same broader MENA region as Sater-solar, with similar customer segments (industrial, commercial, fuel retail kiosks) and reliance on local-grid-connected projects.
