Delivering Long-Term Performance, Beyond Installation
Solar Operations & Maintenance (O&M) for Installers
Installing a solar PV system is only the beginning. Long-term performance, reliability and return on investment are defined by how well that system is monitored, maintained and optimised over time.
TEST works in partnership with solar installers to provide independent, evidence-led Operations & Maintenance (O&M) services, ensuring installed systems continue to perform as designed, while protecting your reputation and strengthening your client relationships.
Whether supporting as a delivery partner, a white-labelled extension of your service, or providing specialist oversight, we enable installers to deliver a robust, long-term O&M solution that complements their core installation offering.
How TEST Supports Solar Installers

Extending
Your Service
Offering
We enable installers to move beyond installation into long-term, recurring revenue service contracts, without the need to build internal O&M resources, allowing installers to focus on their core installation proposition.

Protecting System Performance and Reputation
Underperformance, faults or lack of visibility can quickly impact client trust. Our on-going structured monitoring and reporting ensures issues are identified early and addressed with clear, evidence-based actions.

Providing
Independent,
Technical Reassurance
We bring an additional layer of technical validation and performance assurance, supporting both the original installer and the end client, providing confidence in ongoing system performance and output.

Supporting Client
Retention and
Recurring Revenue
With TEST delivering ongoing O&M services on behalf of installers, installers can strengthen their client relationships, increase lifetime value and create predictable, recurring income streams.

Our role is to complement your offering, not compete with it.
What TEST Does
Solar Monitoring & Performance Management (S.M.A.R.T.)
At the core of our O&M delivery is S.M.A.R.T., TEST’s in-house solar monitoring and performance management platform, designed to provide real-time visibility, control and insight across installed systems.
- Continuous monitoring of generation and system health
- Automated alerts for faults, anomalies and performance drift
- Identification of underperformance against expected yield
- Data-driven insights to prioritise corrective actions
By combining intelligent monitoring with structured analysis, S.M.A.R.T. provides the foundation for effective, ongoing system management – not just visibility.


Proactive Operations & Maintenance
Building on the insights generated through S.M.A.R.T., we deliver a structured, proactive O&M approach focused on intervention and optimisation, not just monitoring.
- Diagnosis and investigation of identified issues
- Root cause analysis of faults and performance gaps
- Coordination and recommendation of corrective actions
- Ongoing optimisation to improve system output over time
Simply put, S.M.A.R.T. identifies or pre-empts issues, while our O&M approach ensures they are resolved and performance is continually improved.
Reporting & Client Visibility
Clear, consistent reporting is key to ensuring installers maintain trust with their clients.
- Monthly, tailored performance reports, incorporating installer branding
- Up to 40 configurable data points
- Clear summaries of performance, issues and actions
- Evidence-based insights aligned to financial and operational outcomes
This enables installers to provide clients with transparent, professional and data-led updates, reinforcing long-term value.


Independent Performance Assurance
As an independent partner, TEST provides objective validation of system performance.
- Verification of actual vs expected generation
- Identification of degradation, inefficiencies or design limitations
- Support in resolving performance disputes or queries
- Evidence-led recommendations for optimisation
This protects both installer and client by ensuring decisions are based on accurate, trusted data.
