Electronics for Energy Infrastructure:
Built to Stay in the Field

Energy infrastructure electronics do not get the luxury of regular maintenance windows. Whether monitoring a remote solar farm across the south of England or reporting alarm conditions from a wind turbine array to a major utility control room, the electronics inside these systems must work first time, every time, and keep working across years of continuous operation in the field.

At Arkle Electronic Systems, this is exactly the environment we build for. Our primary product in the energy sector is the Alarm Annunciator Panel: a turnkey-built monitoring and alarm reporting system that has been in active service across solar and wind farm installations for many years, supplied to major UK utility customers. We design, build, test, and warrant this product in the field for five years, a commitment that reflects our confidence in the manufacturing quality behind it.

Alongside our own turnkey product, we manufacture electronics for oil and gas sector customers operating in hazardous area environments, building under their own accreditations with our process discipline and documentation providing the manufacturing foundation their programmes require.

Alarm Annunciator Panels for Solar and Wind Farm Monitoring

Remote renewable energy installations. Solar farms covering hundreds of acres, wind turbine arrays operating miles from the nearest service depot — depend on reliable alarm monitoring and reporting to keep utility operators informed of plant status and to trigger rapid response when conditions change. The electronics that underpin these systems must be robust, long-lived, and able to operate without intervention across the full range of outdoor conditions they encounter.

Arkle's Alarm Annunciator Panel is a turnkey product that has been developed and refined over many years of deployment across solar and wind farm installations serving major utility customers. Each unit is designed, assembled, tested, and documented at our Stevenage, Hertfordshire facility before despatch, and is warranted in the field for five years from installation. This is not a generic electronics assembly: it is a proven, field-tested product with a service history in the UK renewable energy infrastructure.

What the Alarm Annunciator Panel Does

The panel monitors alarm conditions across the installation and reports status to remote control systems and utility operators. In a solar or wind farm context this covers fault detection across inverters, switchgear, transformers, and ancillary plant, with configurable alarm outputs and communications interfaces that connect the installation to the utility's monitoring infrastructure.

Why Turnkey Matters

Arkle manages the full build: component procurement, PCB assembly, box build, wiring, functional test, and documentation. Customers receive a finished, tested, warranted product rather than a collection of assemblies to integrate on site. This turnkey approach reduces programme risk, shortens the path from order to installation, and gives utility customers a single point of accountability across the product life.

Five-Year Field Warranty

The five-year field warranty on our Alarm Annunciator Panel reflects the manufacturing quality and component selection that goes into every unit. In a sector where plant downtime carries real financial and operational consequences, a manufacturer willing to stand behind their product in the field for five years is making a statement about the quality of what they build. We build it right, and we stand behind it.

Oil and Gas Electronics: Hazardous Area Manufacturing

Arkle manufactures electronics for customers operating in oil and gas hazardous area environments. Our customers in this sector hold the relevant ATEX, UKEX, and IECEx product certifications for their equipment; our role is to provide the manufacturing quality, process discipline, and documentation that their certified programmes require.

Understanding Hazardous Area Zones

Oil and gas facilities, refineries, and offshore platforms classify their working environments into hazard zones based on the likelihood of explosive atmospheres being present. Zone 0 is a location where an explosive atmosphere is continuously present. Zone 1 is where it is likely during normal operation. Zone 2 is where it occurs only in abnormal conditions. The electronics deployed in each zone must be manufactured to the protection concept specified for that zone, whether intrinsic safety (Ex i), flameproof enclosures (Ex d), or another recognised protection method under the IEC 60079 series standards.

ATEX (Directive 2014/34/EU) governs hazardous area equipment in the European Economic Area. UKEX is the GB-market equivalent introduced post-Brexit, governed under DSEAR 2002 and using the same BS EN 60079 series technical standards. IECEx is the international scheme covering approximately 50 countries. Our customers hold the relevant certifications for their products; Arkle provides the manufacturing foundation those certifications rest on.

What Hazardous Area Electronics Demand from Their Manufacturer

For electronics that will be incorporated into ATEX or UKEX certified products, the manufacturing process must be consistent, controlled, and fully documented. Component traceability, process records, inspection documentation, and non-conformance management are not optional: they form part of the technical file that supports the product certification and the audit trail that certification bodies and end customers require.

Arkle's ISO 9001:2015 quality management system provides the framework for this level of documentation and process control. Our PCB assembly processes reference IPC-A-610 for workmanship acceptance, our cable and harness assembly follows IPC/WHMA-A-620, and our conformal coating processes are applied and documented to IPC-CC-830C. For customers building ATEX-certified products, this gives them a manufacturing partner whose processes and records can support their certification requirements.

Offshore and Onshore Applications

Hazardous area electronics for oil and gas applications include process control and instrumentation, gas detection and safety systems, flow measurement electronics, power distribution management, and communications and SCADA interface assemblies. Both offshore platform and onshore refinery and pipeline applications are supported, with conformal coating and box build specifications matched to the environmental conditions of each installation.

Renewable Energy Electronics: Supporting the UK's Energy Transition

Beyond our own Alarm Annunciator Panel product, Arkle manufactures electronics for renewable energy equipment companies across a range of applications. The UK government's sustained investment in clean energy infrastructure, targeting more than 30 billion pounds per year by 2035 — is driving consistent demand for UK-based electronics manufacturing capability across the sector.

Solar and Wind Farm Monitoring and Control

Monitoring, data acquisition, and alarm management electronics for solar and wind farm installations. These systems must operate reliably in outdoor environments across wide temperature ranges, with the conformal coating and IP-rated enclosures that sustained field deployment requires.

Offshore Wind Electronics

Nacelle and turbine electronics for offshore wind installations face the combined demands of salt-laden marine atmosphere, sustained vibration from the rotor and drivetrain, and wide thermal cycling across years of continuous operation. Conformal coating, sealed connector interfaces, and vibration-resistant assembly processes are standard requirements for electronics destined for offshore wind environments.
