NC5 Application Submission Service – For PV Systems Over 200kW (Three Phase)

Large-Scale Solar PV Projects Over 200kW

The NC5 application is required for large-scale solar PV installations exceeding 200kW and involves a significantly higher level of technical and compliance detail than standard ESB applications.

The NC5 Application – Done For You service is designed for installers, developers, and EPCs who want the entire ESB application process managed professionally, ensuring submissions are accurate, compliant, and aligned with ESB Networks’ technical requirements.

At Solar Admin Ireland, NC5 applications are handled by a solar industry professional with over 15 years’ hands-on experience, including large-scale and commercial projects. We understand the additional technical scrutiny involved and manage the process accordingly.

What This Service Includes

We manage the NC5 application process end to end, including:

• Preparation and submission of the full NC5 application to ESB Networks
• Letter of Authorisation prepared and issued for signature
• Detailed block diagram and system overview prepared in line with ESB requirements
• Coordination of additional technical documentation where required
• Ongoing administrative support throughout the application process

All documentation is reviewed carefully before submission to reduce delays, follow-up queries, or requests for clarification.

Designed for Complex, High-Capacity Projects

This service is suitable for:

• Commercial solar developers and EPC contractors
• Electrical contractors delivering high-capacity PV installations
• Utility-scale or large commercial solar projects
• Projects requiring formal ESB grid connection approval

By outsourcing the NC5 application, project teams can focus on engineering, design, and delivery while knowing that the ESB submission process is being handled correctly.

A Professional Approach to Advanced ESB Applications

NC5 applications require precision, structure, and experience.
The NC5 Application – Done For You service provides a reliable, professional route through the most complex ESB application stage, helping projects progress smoothly and compliantly.

Once system details are provided, Solar Admin Ireland manages the application process from preparation through to submission and ongoing coordination.
