What Ohk energy does

Ohk energy is an Ireland-based renewable energy installer and retrofit specialist operating across the Republic of Ireland and Northern Ireland. Formed in 2024 through the merger of NRG Panel and JFW Renewables and the subsequent acquisition of Crest Pro Power and ProEx Engineering, the company delivers end-to-end solar PV, air-to-water heat pumps, battery storage, EV chargers, electrical contracting, and home retrofits to residential, commercial, agricultural, educational, and utility customers, with 15,000+ customers served and 260 employees across four office locations (Castleblayney, Kilchreest/Galway, Ballycastle/Mayo, Dublin). The company self-positions as Ireland's largest renewable energy installer, holding SEAI One Stop Shop and standard installer registrations, Safe Electric and F-Gas accreditations, and Triple ISO certification (9001, 14001, 45001).

The core technology stack is centred on third-party hardware from leading inverter, panel, heat pump, EV charger, and battery vendors (e.g., Myenergi, Heatmiser), supplemented by two proprietary branded products — AiO Konnect (integrated inverter plus battery bundle) and Storm Konnect (resilience-focused system) — each paired with their own monitoring/control app. Engineering and design services are delivered in-house via ProEx Engineering, while electrical contracting capability sits within the Crest Pro Power unit. Digital touchpoints include self-serve grant calculators (SEAI solar, heat pump, and One Stop Shop estimators) embedded in the marketing site, enabling direct online customer acquisition alongside partner-sourced leads.

Revenue is generated primarily through one-time installation contracts at project ticket sizes ranging from approximately €8,000 (entry-level solar PV) to €13,000–€17,000 (heat pumps) up to €42,875–€64,507 before SEAI grants (One Stop Shop deep retrofits), with additional recurring revenue from lifetime warranty servicing, maintenance contracts, and commercial/grid-scale EPC work. Go-to-market blends a direct sales force, self-serve digital channels, channel partnerships with Electric Ireland and Harvey Norman, and embedded green financing through Finance Ireland to compress customer acquisition friction on higher-ticket projects. Recognised as a Deloitte Best Managed Company 2025, Ohk energy's model is fundamentally an installation services business at scale rather than a software or technology platform.

Expansion highlights7 records

Direct peers

• Sunsure Energy: Sunsure is a UK residential solar PV installer offering end-to-end design, installation, and monitoring with proprietary technology - a direct competitor to Ohk energy in the residential rooftop solar category across Ireland/UK with comparable business model and product offering.
• Phoenix Energy: Northern Ireland-based renewable energy installer delivering solar PV, battery storage, and heat pump solutions to homes and businesses - a direct competitor for customers on the same island of Ireland geographic footprint.
• Otovo: Norway-listed residential rooftop solar, battery and heat pump installer across Europe. Closely comparable business model to Ohk energy: full-stack residential renewable energy installation with proprietary technology, financing partnerships, and recurring service revenue. Otovo's market expansion playbook mirrors Ohk energy's Irish roll-up approach.
• Activ8 Solar Energies: Activ8 is one of the larger Irish solar PV and battery installation companies operating across the Republic of Ireland, directly competing with Ohk energy in the same residential and small commercial retrofit segment using SEAI-registered installer credentials.
• Greener Homes Ltd: Irish residential renewable energy installer offering solar PV, heat pumps, and home retrofit services as a SEAI-registered installer. Direct competitor for the same Irish homeowner customer base that Ohk energy targets.

Others

• Enphase Energy: Enphase is a leading global supplier of microinverters and battery energy systems used in residential solar installations. Comparable as an enabling technology provider whose products (microinverters, IQ batteries) form part of the solar+storage ecosystem that Ohk energy integrates and competes with on system architecture.

Broad incumbents

• SunPower Corporation: SunPower is a global residential solar and energy services company offering end-to-end rooftop solar, battery storage, and EV charging solutions. Comparable to Ohk energy in the integrated residential renewable energy services model, though operating at materially larger scale and with broader geographic reach.
• EDF Renewables UK: EDF Renewables is a large incumbent utility-backed renewable energy developer and operator in the UK and Ireland, with utility-scale solar development capabilities directly comparable to Ohk energy's grid-scale solutions offering, though at materially greater scale.
• Electric Ireland (ESB): Electric Ireland is Ireland's largest energy retailer and a current channel partner of Ohk energy. Comparable as a broad incumbent with deep customer reach and the financial capacity to launch in-house solar offerings, posing both partnership upside and competitive risk.
• SSE Airtricity: SSE Airtricity is one of Ireland's largest energy suppliers and a broad incumbent operating across generation, supply, and increasingly home energy services including solar. Comparable as an adjacent renewable energy / energy services player with substantially greater scale, though not a specialist installer.
