Commercial Solar Design Specialist – Design + Client Facing
Hybrid | Office, Site & Client-Based
The Opportunity
We're looking for a Commercial Solar Design Specialist who can combine strong technical PV design skills with confident client communication.
This is a genuine 50/50 design and client-facing role — you'll design commercial Solar PV systems, then get in front of clients to explain the solution, performance and commercial return.
If you want to see your designs become real projects rather than sit behind a screen, this is the role.
What You'll Be Doing
Design – 50%
- Design commercial Solar PV systems from concept through to installation
- Produce layouts, string designs, shading and yield calculations
- Select panels, inverters, mounting and associated equipment
- Complete site assessments and develop buildable designs
- Produce drawings, schematics, specifications and handover information
- Ensure designs meet DNO, grid, Building Regulations and industry standards
- Work closely with installation and delivery teams
Client – 50%
- Attend commercial client meetings and site visits
- Present PV designs and explain technical solutions clearly
- Discuss energy savings, ROI, payback and system performance
- Answer technical questions around equipment, warranties and maintenance
- Support proposals, surveys and technical sales activity
What We're Looking For
- 2+ years' commercial Solar PV design experience
- Strong technical understanding of PV systems and components
- Experience with PVsyst, HelioScope, AutoCAD or similar
- Confident presenting to commercial clients
- Able to translate technical information into clear commercial benefits
- Understanding of DNO / grid connection processes
- Full UK driving licence and willingness to travel
Desirable
- Battery storage / EV / wider energy systems experience
- Commercial energy project delivery
- Equipment specification and supplier experience
What's On Offer
- Competitive salary DOE
- Genuine hybrid working
- Mix of design, site visits and client meetings
- Exposure to major commercial Solar PV projects
- Opportunity to influence projects from initial concept through to installation
- Varied role with genuine progression
The Opportunity
A great opportunity for a Solar PV Designer who wants more than design — more client exposure, more ownership and the chance to see your work turn into real commercial installations.
If you can design it and confidently sell the solution, we want to hear from you.
