Solar power systems can degrade, drift, and lose efficiency over time. Rubikon offers engineering-focused operations and maintenance services to restore energy generation, ensure safety, and extend the lifespan of your photovoltaic (PV) system. We work with residential, commercial, agricultural, and multi-apartment solar plants, regardless of who originally installed them.

What We Handle
- Emergency repairs and fault recovery
- Preventive maintenance and technical audits
- Thermography and IV-curve diagnostics
- Inverter repair, replacement and firmware updates
- Cable route inspection and restoration
- Zero-export verification and adjustment
- BESS diagnostics and capacity upgrades
Typical Problems We Solve
- Sudden or gradual drop in generation without clear reasons
- Inverter errors (Fault, Grid Lost, Overvoltage, Overheating)
- Damaged panels after hail, storms or voltage spikes
- Burned, oxidized or loose MC4 connectors
- PID / LID degradation, microcracks, hotspots
- Cable damage or poor string balancing
- Zero-export malfunction or unstable grid interaction
Repair & Recovery Services
- Inverter diagnostics (e.g., Huawei, Deye, Solis)
- String inspection and IV curve tracing
- Inspection of MC4 connectors, fuses, relays, and breakers
- Measurement of grounding and insulation resistance
- Detection and replacement of overheating panels
- Repair of cable routes and balancing of strings
- Firmware updates and recalibration for zero-export functionality
- Mechanical inspection of mounting systems
When Repair Is Critical
- Generation drops with no visible explanation
- System becomes unstable after storms or grid events
- Inverter reboots, overheats or produces abnormal noise
- Burning smell, sparking or overheating cables
- Visible panel damage, dark spots or cracks
- One string works while others are offline
- Delaying repair increases energy losses and safety risks.
Why a Technical Audit Is Needed
- Identify hidden losses at string or inverter level
- Verify installation quality and grounding
- Optimize generation before high-sun seasons
- Confirm warranty or insurance claims
- Prepare technical reports for asset sale or upgrades
What Maintenance Includes
- Thermal imaging (drone or handheld)
- IV-curve tracing of each string
- Grounding and insulation resistance testing
- Protection and breaker selectivity checks
- SCADA log analysis and comparison with PVsyst model
- Zero-export verification and tuning
- Connector replacement and string balancing
- Panel cleaning and mounting inspection
Energy Audit
An energy audit evaluates how generated electricity is actually used on-site.
We analyze:
- consumption profiles by circuits
- load distribution and inefficiencies
- tariff usage and peak loads
- real vs projected savings
Benefits of Regular O&M
- +10–25% generation increase after optimization
- Extended lifespan of panels and inverters
- Reduced fire and short-circuit risks
- Full technical report with recommendations
- Confidence and control over system performance
How We Work
- Initial consultation and remote data review
- On-site inspection: measurements, thermography, IV-curves
- Technical report with loss analysis and recommendations
- Repair or optimization (if required)
- Ongoing monitoring and maintenance

FAQ
At least once per year. After 4-5 years of operation, twice per year is recommended.
No. Most tests are performed without stopping generation.
From 2 to 10 hours, depending on system size.
Yes, but the most accurate results are obtained during sunny periods
Yes. We provide independent diagnostics and service.
