Job description

Our client is seeking a key hire, a Solar Design Engineer, who will lead the technical design and optimisation of our solar photovoltaic (PV) and battery storage systems. This role is essential in shaping effective, high-performance renewable energy solutions tailored to commercial and industrial clients. Reporting into the Head of Solar Engineering, the Solar Design Engineer will work closely with our sales, project, and operations teams to create innovative, cost-effective, and sustainable designs that meet site requirements, client goals, and regulatory standards. The ideal candidate will have a strong background in solar PV system design and performance modelling, along with experience in integrating battery storage solutions.

Key Responsibilities

Develop detailed solar PV system designs, including electrical layouts, panel configurations, and single-line diagrams, ensuring designs align with client specifications, site conditions, and regulatory standards.

Utilise design software (e.g., PVSyst, Helioscope, Trimble, AutoCAD) to model energy output, calculate yield, and optimise system performance.

Design battery storage integration for hybrid systems, focusing on sizing, config, and operational strategy to enhance energy efficiency and storage capacity.

TechnicalFeasibilityandSiteAssessment

Conduct technical site assessments, analysing factors such as irradiance, shading, roof or ground conditions, and structural requirements.

Prepare feasibility studies, energy production forecasts, and technical reports for client presentations, supporting the business case for each project.

Coordinate with Project and Sales teams to refine design solutions based on customer goals and site-specific requirements.

Regulatory Compliance and Documentation

Ensure all designs adhere to relevant industry standards, codes, and safety regulations.

Prepare required documentation, including G99 applications and CLS forms, grid connection agreements, including CNO documentation, and planning permission submissions.

Support the Project Team with technical input during installation and commissioning, troubleshooting any design-related issues that arise.

QualityAssuranceand Continuous Improvement

Implement quality control checks to ensure accuracy and functionality of designs before project deployment.

Stay informed about advancements in solar PV technology, battery storage, and regulatory changes, integrating best practices into the design process.

Identify and implement improvements to the design process to increase efficiency and project quality.

Key Requirements

Educational Background: Bachelor’s degree in Electrical Engineering, Renewable Energy Engineering, or a related field.

Experience: 3+ years in solar PV design, ideally in commercial and industrial applications.

Technical Proficiency:

Proficient in design software such as PVSyst, Helioscope, Trimble and AutoCAD.

Strong understanding of PV technology, energy yield modelling, and system performance optimisation.

Knowledge of battery storage design and integration, as well as familiarity with grid connection standards (e.g., G99 compliance).

Analytical Skills: Strong analytical skills to conduct feasibility analysis, identify design solutions, and optimise system efficiency.

Communication Skills: Excellent communication skills for collaborating with cross-functional teams and presenting technical information to clients.
