Keeping Your Solar System at Peak Performance

From daily monitoring, preventive inspection and thermal scanning to panel cleaning and defect rectification: a complete O&M system that keeps every rooftop producing.

Why O&M

Why O&M Matters

Solar systems need regular maintenance to keep performing at their best. Dust build-up on industrial rooftops reduces generation, lowers returns and stretches the payback period.

Dust Build-up

Dust accumulates on solar panels, reducing the sunlight reaching the cells and lowering energy output.

Bird Droppings & Stains

Localised shading creates hot spots that damage the modules over time.

Shading

Trees or new structures shade the array, causing string mismatch and lower output.

Equipment Ageing

Corroded mounting, degraded cable terminations and failed earthing are safety risks.

Regular inspection and cleaning significantly reduce degradation, extend equipment life and catch problems early.

Before & After

Before and After Cleaning

Same site, same day. In the morning the modules sat under a layer of dust. After one clean they are clear again. Every day that dust stays, it blocks sunlight and takes generation with it.

Cleaning is the most immediate result in O&M. We keep before and after photo records for every clean, so the result can be checked.

O&M Services

From cleaning, inspection and thermal scanning to testing and rectification: every stage of the PV system lifecycle.

Site Works
01Panel cleaning

Panel Cleaning

  • Optional service, scheduled to how soiled the modules are
  • Professional equipment with water and non-corrosive solvent
  • Restores light transmission and generation
  • Before-and-after records for every clean
02Inverter and DC distribution equipment checked with a thermal camera

System Inspection

  • Inverters and DC/AC distribution boards checked unit by unit
  • DC isolators, cable terminations and fasteners verified one by one
  • Infrared temperature checks on switchgear and terminals
  • Mounting structure, fastener torque and earthing continuity checked
03Defect rectification

Defect Rectification / Repair

  • Defects found during inspection rectified on site
  • Loose modules re-tightened, degraded cable terminations replaced
  • Before-and-after records issued as a rectification report
  • Replacement parts quoted separately, costs fully transparent
Data & Testing
04Thermal scanning

Thermal Scanning

  • Module-level hot spot detection for faults invisible to the eye
  • High-temperature detection on DC cable joints
  • Early warning before a fault escalates
05Voc and RISO string testing

Voc / RISO String Testing

  • Open-circuit voltage (Voc) measured string by string against design values
  • Insulation resistance (RISO) testing to detect insulation degradation
  • Ensuring every string runs at its best
06Monitoring platform

Daily Monitoring & Alerts

  • Daily monitoring of system status and alarms on our platform
  • First response to any abnormality, around the clock
  • Monthly alarm summary and generation analysis
Service Cadence

Service Cadence & Response

A defined rhythm of service, written into the contract.

1× / Year

Annual Site Inspection

Torque check, electrical connection check, earthing continuity test and switch board inspection in a single visit.

2× / Year

Panel Cleaning

Carried out with professional equipment, water and non-corrosive solvent; frequency can be increased depending on how soiled the modules are.

24 / 7

Alarm Response

The monitoring platform watches for alarms at all times; any system abnormality gets a first response immediately.

Monthly + Annual

Reporting

Monthly alarm summaries and generation analysis, annual inspection checklists and string test reports, all on file.

Reporting

Reports & Deliverables

Every inspection and every rectification is documented, so system status is always clear.

Monthly maintenance report

Monthly Maintenance Report

Monthly alarm summary, generation analysis and system status records.

Annual maintenance report

Annual Maintenance Report

Annual inspection checklist, string test records and full-year generation analysis.

Generation analysis

Generation Analysis

Month-on-month and year-on-year comparison to confirm the system is performing at its best.

Rectification report

Rectification Report

The issues found, how they were handled, and complete before-and-after records.

O&M Value

The Value of O&M

Professional O&M is more than wiping panels down. It protects your long-term returns.

01

Prevent Problems Early

Avoid fire and unplanned downtime: catch corroded mounting, poor cable terminations and failed earthing before they become incidents.

02

Sustain High Generation

Sustain high generation and healthy investment returns, so income stays steady.

03

Detect Early, Extend Life

Detect system issues early and extend the system's service life, keeping the asset valuable.
