What Solarfix does

Solarfix is a Northern Ireland-based solar PV design and installation company serving residential, commercial, agricultural, and specialty customers (including golf clubs and off-grid properties) across the UK and Ireland. Founded in 2015 and operating as Solarfix NI Limited (Company Nr: NI633185) from its Newtownabbey headquarters (Unit 66 Mallusk Enterprise Park, BT36 4GN), the company specializes exclusively in solar photovoltaic systems, supported by a team with over 20 years of industry experience. As of 1 November 2025, Solarfix reported 2,104 installations completed, 16,869,926 units of electricity produced by those systems, and 4,217,471 kg of CO2 saved by customers. The company is led by Managing Director Michael O'Donnell.

The product portfolio spans commercial solar, domestic solar, agricultural solar, new-build solar, golf-club installations, and off-grid systems, complemented by add-on modules including battery storage (with Duracell Energy Platinum Partner status), EV chargers (via myenergi), immersion heater controllers, and SolarEdge-optimised inverters. Solarfix partners with hardware suppliers including JA Solar, Q Cells, SolarEdge, Solis, BYD, Victron Energy, PureDrive Energy, and myenergi, and holds sector-relevant credentials: MCS installer certification (UKAS-audited), ISO 9001/14001/45001, RECC membership, IWA deposit protection with 10-year guarantee insurance, CSR registration, and Trading Standards approval.

Commercial operation is sales-led: customers reach Solarfix through a freephone number (0800 246 5198), website contact forms, and field consultations, supported by content marketing (blog, case studies, FAQs), social media (Instagram, Facebook, LinkedIn, YouTube), and partnerships such as Ulster Rugby sponsorship. Revenue is generated almost entirely through one-time installation fees on a project-by-project basis, with no disclosed recurring or subscription component; commercial systems are marketed at 3-5 year payback, 25-year performance warranties, and ROI exceeding 20%. In December 2024, the company secured €1.8 million from Whiterock to finance expansion across the UK and Ireland, product development, recruitment, and project installations.

Scale indicators6 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• EDF Renewables UK: EDF Renewables UK is a major UK solar and wind developer operating utility-scale and distributed generation projects. While much larger than Solarfix, it competes in commercial/utility solar EPC and increasingly in distributed rooftop solar, overlapping with Solarfix's commercial segment.
• Lightsource bp: Lightsource bp is one of Europe's largest solar developers, focused on utility-scale and increasingly commercial/industrial PV. As a broad incumbent with deep UK project pipeline, it competes in the larger commercial projects that Solarfix aspires to bid for.
• Statkraft UK: Statkraft acquired SolarCentury in 2020 and operates one of Europe's largest solar development pipelines. As a broad incumbent with utility-scale focus and UK presence, Statkraft is a relevant comparable for the enterprise/commercial end of Solarfix's market.
• Octopus Energy: Octopus Energy is a major UK energy retailer that has expanded into solar panel and heat pump installation via Octopus Solar and Kraken. As a broad incumbent with brand scale and financing options, it competes for the same residential and commercial customers Solarfix targets.

Others

• SolarEdge: SolarEdge is a leading global manufacturer of solar inverters, power optimizers, and module-level monitoring. It is a technology partner to Solarfix and adjacent rather than competing — but its product roadmap and pricing directly shape Solarfix's margin structure.
• JA Solar: JA Solar is one of the world's largest manufacturers of crystalline silicon solar cells and modules. A core panel supplier to Solarfix, it is adjacent rather than competing; its wholesale pricing and product availability materially affect Solarfix's cost of goods.

Direct peers

• Midsummer Energy: Midsummer Energy is a UK-wide solar PV installer serving residential and commercial customers with battery storage and EV charging add-ons. It is a direct competitor to Solarfix in the same MCS-certified solar EPC category across overlapping UK geographies.
• Infinity Energy: Infinity Energy is a UK solar PV and battery storage installer targeting residential and small commercial customers. Comparable to Solarfix in target segment, technology stack (tier-1 panels, hybrid inverters), and direct-sales GTM model.
• Carbon Legacy: Carbon Legacy is a UK installer of solar PV, battery storage, and EV charging solutions for homeowners and businesses. Comparable to Solarfix across product portfolio, customer segments, and sales-led GTM motion.
• Eco2Solar: Eco2Solar is a UK-based solar PV installer focused on residential new-build and commercial developments. Like Solarfix, it bundles panels, inverters, and battery storage; its strength in new-build housing is particularly comparable to Solarfix's "New Build Solar" line.
