Your Commercial Solar Asset, Managed

Commercial solar systems are assets — and assets need managing. A 100kWp rooftop system represents a £70,000-£95,000 investment, and it needs to perform every day for 25 years to deliver the expected ROI. We manage commercial solar systems across the UK with quarterly inspections, remote monitoring, SLA-backed fault response, and annual performance reporting. Our operations team monitors your system around the clock, and our engineers respond faster than any other solar O&M provider in the North West. We started as a maintenance company — not an installation company that offers maintenance as an afterthought. This is our core business, and we're very good at it.

What's Included in Our O&M Contracts

Quarterly Inspections

Every O&M contract includes quarterly visual and electrical inspections — catching developing faults before they impact generation and ensuring your system is always operating at peak performance.

SLA-Backed Response

Critical faults (DC isolator failure, fire risk): 4-hour response. Major faults (inverter failure, string outage): 24-hour response. Minor faults: 5 working days. All response times guaranteed by SLA.

Annual Electrical Testing

Annual BS 7671 electrical testing including insulation resistance, earth fault testing, and full inverter inspection — providing the documentation your insurance and building managers require.

Remote Monitoring

We set up and maintain remote monitoring on all O&M systems, with automated alerts for underperformance, inverter faults, and communication failures — so we know about problems before you do.

Performance Reporting

Monthly generation reports compare actual output against predicted performance (PR ratio), quantify losses, and track trends — giving you complete visibility of your asset's performance.

Cleaning Included

Annual professional cleaning is included in all O&M contracts — using our deionised water system to maintain panel efficiency and ensure your system performs to design throughout the year.

How It Works

Step 01

System Audit

We start every new O&M contract with a full system audit — reviewing installation documentation, current performance vs design, monitoring configuration, and any outstanding faults.

Step 02

Contract Setup

We configure remote monitoring alerts, establish baseline performance metrics, set up your client portal, and issue your service level agreement.

Step 03

Quarterly Inspections

Every quarter, an engineer visits your site for a full visual and electrical inspection. You receive a written inspection report within 5 working days of each visit.

Step 04

Annual Review

At contract renewal, we provide a full-year performance analysis: generation vs design, fault history, cleaning records, and recommendations for the next contract year.

Frequently Asked Questions

Our standard O&M contract includes: remote monitoring setup and management, quarterly on-site inspections, annual BS 7671 electrical testing, one professional cleaning visit, SLA-backed fault response, and monthly performance reports. Cleaning frequency and visit schedules can be customised for your site.
