Solutions Architect (Commercial and Industrial (C&I) Solar)

We are looking for a Solutions Architect (C&I Solar) to join our growing renewable energy team. This is a technical, client-facing role responsible for owning the front end of our Commercial & Industrial (C&I) solar opportunities — from understanding the client's site and energy requirements to developing a technically sound and costed solar solution. You will work closely with clients, Business Development (BD) and our EPC/installation team to assess feasibility, develop preliminary system designs, prepare project costing and provide the technical foundation for commercial proposals.

Key Responsibilities:

• Conduct feasibility studies and site assessments at C&I premises, including evaluation of usable roof area, structural loading, orientation, shading, roof condition, cable routes and electrical/plant room access.

• Engage with clients to understand their energy requirements, load profile, electricity consumption, tariff, budget and preferred financing model, including outright purchase, PPA or leasing.

• Develop preliminary solar PV system designs, including array layouts, string configurations and inverter selection based on site conditions and client load profiles.

• Perform energy yield and system sizing analysis using PV design and simulation tools such as PVsyst, Helioscope or equivalent.

• Prepare project costing and Bill of Quantities (BOQ), covering equipment, balance of system (BOS), mounting structures, installation and other technical requirements.

• Assess regulatory and grid connection requirements, including SP PowerGrid, EMA and LEW/QP requirements, and identify potential technical, cost or timeline implications.

• Prepare clear and structured technical scope and costing packages for the BD team to develop commercial proposals.

• Support BD during tender submissions, client presentations, negotiations and technical clarifications.

• Work closely with the EPC/installation team to ensure proposed solutions are practical, buildable and aligned with project specifications and PV layout standards.

• Coordinate with LEW/QP on formal electrical designs, Single Line Diagrams (SLD) and regulatory submissions where required.
  

Requirements:

• Degree in Electrical, Mechanical, Energy Engineering or a related discipline.

• At least 3 years of relevant experience in solar PV design, C&I EPC, renewable energy solutions or technical pre-sales/solutions roles.

• Strong understanding of C&I rooftop solar PV systems and the ability to assess site and roof feasibility.

• Good knowledge of LV electrical systems, grid connection requirements and solar PV system components, including modules, inverters and protection systems.

• Experience in project costing, BOQ preparation and the ability to validate and defend technical assumptions and pricing.

• Working knowledge of Singapore's solar regulatory and grid connection requirements, including SP PowerGrid, EMA and LEW/QP requirements.

• Proficiency in solar PV design and simulation software such as PVsyst, Helioscope or equivalent, as well as AutoCAD.

• Strong client-facing and communication skills, with the ability to explain technical concepts and trade-offs clearly to non-technical stakeholders.

• Strong analytical and problem-solving skills with a practical, commercially minded approach.
  

Why Join Us

• Be part of the growing renewable energy and solar industry.

• Own the technical solution from initial site assessment through to a buildable and costed project scope.

• Work directly with clients and cross-functional teams across BD, EPC and project delivery.

• Enjoy a role focused on technical solutions and project development, rather than cold-calling or pure business development.

• Gain exposure to a wide range of C&I solar projects and commercial energy solutions.
