Location: Leicestershire

Salary: Competitive Salary

Working arrangement: Onsite

Overview Are you an experienced electrical engineering or renewable energy professional with a strong background in commercial Solar PV design, battery energy storage and technical leadership?

We are seeking a Lead Solar PV Design and Engineer to lead the technical and design functions across commercial and industrial renewable energy projects, including Solar PV, Battery Energy Storage Systems (BESS), EV charging and associated electrical infrastructure.

This is a senior technical leadership role combining engineering design, electrical compliance, technical governance and team development. You will take ownership of design standards, review and approve complex engineering solutions, maintain compliance requirements and ensure projects are designed to be safe, commercially viable and practical to install.

Working closely with Sales, Operations, Project Management, Procurement and installation teams, you will improve design quality, support project delivery, optimise costs and develop the technical capability of the business.

Key Responsibilities Technical Leadership and Electrical Compliance:

• Act as the senior technical authority for Solar PV, BESS and associated electrical infrastructure.
• Oversee electrical design standards, technical governance, quality assurance and design approval processes.
• Ensure compliance with BS 7671, G98, G99, G100, DNO requirements, MCS standards and relevant electrical regulations.
• Fulfil the responsibilities of Electrical Duty Holder and NICEIC Qualified Supervisor.
• Maintain relevant accreditations and support technical audits, compliance assessments and root cause investigations.
• Develop and maintain technical policies, procedures, design standards and quality control processes.

Solar PV Design And Engineering

• Lead commercial and industrial Solar PV design from feasibility and concept through detailed design, construction issue, commissioning and as:built handover.
• Review and approve PV layouts, string calculations, single:line diagrams, cable sizing, inverter selection, protection systems, equipment schedules and construction drawings.
• Ensure electrical designs are coordinated, compliant, buildable and suitable for safe installation and ongoing maintenance.
• Maintain robust design checking, revision control and technical sign:off processes.
• Identify and resolve design discrepancies before procurement or construction.

Battery Energy Storage Systems (BESS)

• Lead the development of BESS design standards and methodologies.
• Oversee battery sizing, power and energy requirements, inverter/power conversion system selection and integration with Solar PV.
• Consider client load profiles and objectives, including self:consumption, peak shaving, demand management, resilience and tariff optimisation.
• Apply knowledge of battery technologies, system architecture, energy management and battery installation fire safety.
• Support the development of technically appropriate and commercially viable energy storage solutions.

Mounting Systems And Design Optimisation

• Maintain strong working knowledge of K2 Base+ and relevant Solar PV mounting systems.
• Review roof interfaces, fixing arrangements, loading assumptions, structural information and manufacturer requirements.
• Select safe, compliant and cost:effective mounting solutions without compromising installation quality, structural requirements or warranties.
• Work with Procurement and Operations to improve equipment standardisation and reduce unnecessary material and installation costs.

Commercial And Operational Support

• Ensure consistency between sales proposals, PV*SOL/PVsyst models, AutoCAD layouts, mounting designs, equipment schedules and fi
