- Develop and review yield assessments, system performance models, and technical reports.
- Collaborate with commercial, project management, and delivery teams to ensure designs are practical and cost-effective.
- Provide technical input into tender submissions and client proposals.
- Review and validate third-party designs to ensure compliance with TSG standards and industry best practice.
- Ensure all designs meet relevant UK standards, grid requirements, and regulatory obligations.
- Liaise with Distribution Network Operators (DNOs) and other stakeholders as required.
- Identify risks, constraints, and opportunities during the design phase and propose solutions.
- Support project handover from pre-construction to delivery teams, ensuring technical clarity and continuity.
- Maintain up-to-date knowledge of solar and BESS technologies, standards, and market developments.
