Real-World O&M Impact

Why Solar Panel Cleaning & Thermal IR Scans Matter

Tropical dust, pollen, and vehicular soot bake onto glass under intense sunlight, causing localized hot spots and reducing string current.

🌧️ Unmaintained & Soiled Array −18% to −25% Loss
  • Permanent dust crust blocks solar photon absorption
  • Bird dropping hotspots cause bypass diode burnout
  • Undetected terminal looseness risks thermal electrical fires
  • Estimated lost revenue: ₱3,500 – ₱7,000 / month on 10kWp
☀️ Professionally Cleaned & Verified 100% Rated Yield
  • De-ionized water leaves spotless, anti-static glass
  • Thermal IR scanning verifies zero microcracks or cell hot spots
  • Torque-tested electrical terminals guarantee continuous uptime
  • Full 25-year manufacturer equipment warranty protection
Quality Assurance Workflow

Our 4-Stage Solar Installation & Commissioning Process

Every step is managed by certified engineers to ensure rapid execution, zero roof leaks, and maximum 25-year energy generation.

01

Site Survey & Shading Simulation

We inspect your roof pitch, compass azimuth orientation, structural truss loading capacity, and surrounding tree/building shading obstacles. We analyze your electricity bill to calculate the optimal capacity in kWp.

02

Engineering Blueprint & Permitting

Our registered electrical engineers produce certified Single-Line Diagrams (SLD), string voltage layouts, and wire/breaker sizing schedules. We prepare all documentation for municipal permits and utility net-metering.

03

Mechanical & Electrical Installation

Certified solar technicians install anodized aluminum mounting rails with waterproof EPDM rubber gaskets. Modules, DC conduits, high-voltage SPDs, inverters, and battery banks are securely mounted to code.

04

Commissioning, Handover & App Setup

We execute comprehensive Megger insulation testing, string Voc checks, and thermal imaging. We set up your smartphone monitoring app so you can track real-time solar generation, battery status, and savings 24/7.

Preventive Care Checklist

Solar PV Preventive Maintenance Matrix

Regular maintenance ensures your solar panels consistently produce their rated wattage and prevents small electrical issues from becoming costly repairs.

Maintenance Activity Recommended Interval Scope of Inspection Energy & Safety Impact
Solar Module Cleaning Every 3 to 6 Months De-ionized water wash, anti-static wiping, dirt/bird soiling removal Restores 10% to 25% lost generation capacity
Thermal Infrared (IR) Thermography Annually Handheld/drone thermal imaging across all solar cells and junction boxes Detects hot spots, defective diodes, and fire hazards before damage occurs
Inverter & BOS Health Check Semi-Annually Error log analysis, firmware update, heat sink cleaning, terminal torque check Prevents inverter overheating, nuisance tripping, and unexpected shutdowns
Battery Storage (BMS) Calibration Quarterly Cell voltage balancing check, State-of-Charge (SoC) calibration, cycle logs Ensures full 6,000+ cycle lifespan (>15 years) for LiFePO4 cells
Grounding & Surge Arrester (SPD) Check Annually Earth ground resistance testing (<5 Ohms), SPD indicator flag inspection Protects sensitive electronic equipment from indirect lightning strikes
Mechanical Structural Check Annually (Pre-Typhoon) Torque check on mid/end clamps, rail fasteners, and roof flashing seals Guarantees 200+ km/h typhoon wind-load structural resistance
