EPC Services for Commercial Solar
When it comes to commercial solar projects, choosing the right delivery model is crucial. Engineering, Procurement, and Construction (EPC) services provide a streamlined, end-to-end approach that ensures projects are designed, sourced, and built to the highest standard. By offering single-point accountability, EPC services simplify complex solar installations, reduce risks, and deliver high-quality results on time and within budget.
Benefits of Engineering, Procurement, and Construction
Partnering with GB NRG (an EPC provider) brings multiple advantages for businesses considering commercial solar:
- Streamlined project delivery – From system design and procurement of solar photovoltaic cells to installation and commissioning, everything is managed under one roof
- Single-point accountability – One trusted partner oversees the project, ensuring responsibility for quality, timelines, and cost control
- Improved quality control – With in-house expertise in professional electrical integration, efficient inverters, and solar online monitoring tools, system performance and reliability are maximised
- Cost savings and incentives – Businesses benefit from annual investment allowance, tax incentives, asset finance, and government solar incentives, making solar more financially accessible
- Sustainability gains – Integrated EPC delivery helps reduce a company’s carbon footprint, especially when paired with battery storage and export meter setup
Engineering, Procurement, and Construction Process Overview
The EPC process for commercial solar follows a structured and transparent path:
- Initial Consultation – Understanding your energy consumption profile and business objectives
- Site Surveys & Feasibility Assessments – Detailed structural assessments, CAD visuals, and analysis of rooftop or ground-mounted solar systems
- System Design – Creation of bespoke schematics, layout plans, and electrical integration drawings
- Permissions & Compliance – Securing planning requirements, grid approvals, and legal certifications
- Procurement – Sourcing high-quality panels, inverters, and balance-of-system components
- Construction & Installation – Managing the full solar panel installation, including mounting solutions and safety checks
- Commissioning & Warranty – Final system testing, delivery of performance warranty, and handover of maintenance documentation
Regulatory Compliance and Accreditation for EPC Services
Compliance and accreditation are central to successful EPC projects. Businesses must work with accredited partners to ensure safety, reliability, and long-term performance.
- Regulatory adherence – EPC providers manage planning notifications, full plan applications, and approvals with the local planning authority
- Electrical safety standards – Systems are installed with AC & DC isolators, safety isolators, and string controllers, fully aligned with UK regulations
- Certification & accreditation – Reputable EPC contractors are accredited by bodies such as NICEIC, ensuring electrical systems and generation meters meet strict industry standards
- Grid connection consents – EPC partners coordinate with DNOs and energy suppliers to secure grid connection consents and configure export meters
