Silektro

What Silektro does

Silektro s.r.o. is a Prague-headquartered Czech B2B provider of backup power and renewable energy infrastructure, founded in 1993 (one source cites 1990) and operating with 11-50 employees. The company's core products span uninterruptible power supplies (UPS), motor generators in the 3-3500 kVA range, photovoltaic power plants, battery energy storage systems (BESS), and power balancing / system služeb (SVR) services. It reports a cumulative installed photovoltaic base of more than 68 MWp and operates over 32 years of domain history in the Czech market.

The technology stack is multi-vendor rather than proprietary: Silektro integrates generators and OEM equipment from Grupel, EATON, HIMOINSA, and JCB, inverters from Fronius, SMA, and Sungrow, and controls from Deep Sea Electronics and ComAp. Rather than building its own platform, the company assembles turnkey solutions combining hardware supply, installation, commissioning, and recurring service contracts, and has added an operational layer through its Silektro Energy rental business for temporary power needs.

The business model combines one-off equipment sales, turnkey project delivery, and recurring service and rental revenue. Customers identified in available material include the Czech railway infrastructure manager SŽDC, hospitals, HP Enterprise, and Metrostav, spanning transportation infrastructure, healthcare, IT and data centers, commercial and industrial construction, and pharmaceutical sites. Geographic footprint appears concentrated in the Czech Republic with no disclosed international expansion.

Direct peers

• Solar Global: Czech PV EPC and project developer serving C&I rooftops and ground-mounted solar plants in the Czech Republic. Comparable regional competitor in turnkey FVE delivery and subsidy administration for institutional clients.
• Photon Energy: Amsterdam- and Prague-based PV developer and EPC active across the Czech Republic, Central Europe, and Australia. Directly comparable to Silektro in PV project delivery on commercial/industrial and utility-scale segments in the same geography.
• Master Power Elektro: Czech distributor and service provider of diesel generator sets, UPS systems, and electrical power solutions, serving institutional and industrial customers with turnkey delivery. Closely comparable product mix (motorgenerators, UPS, service) in the same Czech market.

Broad incumbents

• ABB (Electrification): Global electrification and power infrastructure supplier with strong Czech presence offering switchgear, transformers, UPS, and microgrid solutions. Competes with Silektro on large infrastructure tenders including rail and utility-scale backup.
• Vertiv: Specialized global provider of critical digital infrastructure including UPS, power distribution, thermal management, and monitoring for data centers and industrial facilities. Comparable in UPS, BESS-adjacent offerings, and remote monitoring for mission-critical sites.
• Schneider Electric: Global energy management and UPS leader (Galaxy, Easy UPS, APC brands) competing across Silektro's UPS and power infrastructure segments. Direct competitor on large UPS deployments but operates across a much broader portfolio of electrical distribution, automation, and software.
• Caterpillar Electric Power: Global manufacturer of diesel and gas generator sets, switchgear, and related power systems with a European dealer network. Comparable on motorgenerator supply for institutional/industrial customers and potential competitor on large Czech infrastructure projects.
• Eaton (Electrical): Major global UPS manufacturer and Silektro's primary UPS supplier; competes with Silektro on enterprise and data-center UPS tenders while also being an OEM partner. Comparable offering across healthcare, rail, and data-center backup power segments.

Emerging players

• Grupel: Portuguese industrial generator manufacturer (1976) supplying motorgenerators from 3 to 3500 kVA globally; Silektro is its Czech distributor. Comparable on product/technology and could potentially be a channel competitor if it expands its own Czech presence.

Regional players

• ČEZ ESCO (now ENERGO-PRO and Teplárenská skupina Římov / ENETIQA): Czech-based energy services provider offering distributed generation, BESS, and energy solutions to commercial and municipal customers across the Czech Republic. Comparable regional focus on behind-the-meter PV/BESS and backup power with stronger balance sheet.
