🏢 About Greencells Group

Greencells Group stands out as a global leader in solar power solutions with a mission-driven focus on building a cleaner future. Their international projects and remote work structure offer unique opportunities to contribute to large-scale renewable energy infrastructure worldwide while maintaining flexibility.

About This Role

This Commissioning Engineer role focuses specifically on the construction and energisation phase of utility-scale solar PV projects, ensuring all electrical systems meet DNO requirements and grid compliance standards. You'll be the technical authority onsite, responsible for validating everything from string testing to SCADA systems before grid connection.

💡 A Day in the Life

A typical day involves reviewing technical documentation remotely, coordinating with onsite teams for testing schedules, analyzing test results from PV arrays and electrical systems, and communicating with DNO representatives about compliance requirements. You might spend mornings analyzing IV curve test data and afternoons in virtual meetings with construction managers to address quality issues before energisation.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk us through your process for commissioning a utility-scale solar PV plant from construction completion to grid connection
2 Describe a challenging situation you faced during DNO coordination for energisation and how you resolved it
3 What specific tests would you perform on HV/MV cables and transformers before energisation?
4 How do you ensure SCADA system validation meets both project requirements and grid operator standards?
5 Given this is a remote role, how would you manage quality control and communication with construction teams onsite?

⚠️ Common Mistakes to Avoid

  • Applying with only residential or small commercial solar experience when they specifically require utility-scale
  • Failing to mention specific grid compliance experience (especially G99 in the UK context)
  • Not demonstrating understanding of the remote nature of the role and how technical oversight works without physical presence
