Sol PV Group

SOL PV, a UK-based installer of commercial solar PV systems, wanted to differentiate in a crowded market. Beyond installation, they needed a way to prove long-term system performance and compliance for clients. By partnering with TEST Consulting, they demonstrated the power of proactive O&M and monitoring, with Central England Co-op as a flagship project.

• Clients lacked visibility into solar system performance.
• Underperformance risked client trust and installer reputation.
• Compliance reporting (ESOS, CRC) demanded reliable, auditable data.
• Installers needed to show lifetime value beyond installation.

• Pre-installation audits and design validation to assure quality.
• Energy audits across 150+ Co-op sites, uncovering 1,290 efficiency opportunities.
• Deployment of SMART monitoring for real-time performance and proactive maintenance.
• Compliance-ready reporting to ease client admin.
• Ongoing O&M partnership, letting SOL PV focus on new installations while TEST handled performance.
• Shifted SOL PV from installer to trusted, long-term strategic partner.
• Optimised performance and compliance for their clients.
• Delivered a repeatable O&M model to roll out across future projects.
• Proved ROI in just 2.1 years, with speed and scale of delivery.

“We approached TEST Consulting to develop a monitoring solution that could provide full visibility across solar portfolios. Their software not only created a digital twin of each installation but also integrated weather data to benchmark expected versus actual performance. This insight has been invaluable, allowing issues to be identified early and resolved quickly, and giving clients maximum uptime with confidence their solar assets deliver the returns they should.”
