Solar System Maintenance
Keep Your Solar Plant Performing at Peak Output
A solar system is a 25-year investment — and like any investment, it needs expert care. Fulminous Green Energy’s maintenance and AMC services ensure your panels, inverters, and wiring deliver maximum generation every single day, year after year.
Why Regular Maintenance?
An unmaintained solar system silently loses money
Dust accumulation, bird droppings, loose wiring, and inverter degradation can silently reduce your solar system’s output by 15–30% within the first two years. Most owners don’t realise their plant is underperforming until thousands of rupees in generation — and savings — have already been lost. Regular professional maintenance restores and sustains peak performance throughout your system’s lifetime.
- Recover up to 25% lost output — professional panel cleaning and electrical checks restore generation to rated capacity within a single visit.
- Protect your warranty — most panel and inverter warranties require documented periodic maintenance to remain valid and claimable.
- Prevent costly failures — early detection of hotspots, micro-cracks, and inverter faults saves lakhs in emergency replacements and lost generation.
- Extend system life beyond 25 years — well-maintained solar plants routinely outperform their design life, generating free energy for decades longer.

Thorough inverter diagnostics covering firmware updates, cooling fan inspection, DC/AC voltage and current checks, error log review, and capacitor health assessment — ensuring your inverter converts every unit of solar power at peak efficiency.
Thermal Imaging & Hotspot Detection
Drone-assisted and handheld infrared thermography identifies hotspot cells, bypass diode failures, delamination, and micro-cracks invisible to the naked eye — catching problems before they cascade into module failure or fire hazard.
Performance Monitoring & Reporting
Remote SCADA-based generation monitoring with monthly performance reports comparing actual vs. expected output. We flag underperformance early and dispatch technicians proactively — so you never discover a fault through your electricity bill.
Electrical & Structural Inspection
Full inspection of DC wiring, MC4 connectors, junction boxes, earthing continuity, lightning arrestors, and mounting structure integrity — identifying corrosion, loose connections, and potential safety hazards before they cause system damage or downtime.
Emergency Breakdown & Repair
Priority on-call service for inverter failures, panel damage, string faults, and grid disconnection events. AMC customers receive guaranteed response times with same-day or next-day on-site attendance — minimising downtime and generation loss.

Who Needs This
Signs your solar system needs professional attention
Whether your system is brand new or several years old, regular maintenance keeps it performing as designed. Here are the key indicators that it’s time to book a service.
✓ Schedule Maintenance If…
- Your solar generation has dropped noticeably compared to the same period last year
- Panels haven’t been cleaned in more than 3 months — especially in dusty or industrial areas
- Your inverter is showing error codes, fault lights, or unexpected shutdowns
- Your system is over 2 years old and has never had a professional inspection
- You’ve experienced heavy rain, hailstorm, or strong winds that may have affected mounting or panels
- You plan to claim a warranty — documented maintenance records are typically required by manufacturers
✗ Common Misconceptions We Address
- “Solar panels are maintenance-free” — panels are low-maintenance, not zero-maintenance. Dust alone causes 10–20% output loss.
- “Rain cleans my panels” — rain streaks dried dust and bird droppings into patches, often worsening soiling over time.
- “My app shows normal output” — monitoring apps compare to current weather, not rated capacity. Slow degradation is invisible without benchmarking.
- “It will be covered under warranty” — most warranties are void if maintenance records cannot be produced during a claim process.
Not sure if your system is underperforming? Book a one-time health check visit with our solar service team. We inspect your full system, benchmark output against rated capacity, and deliver a written performance report — so you know exactly where you stand, with zero obligation to purchase an AMC.

FAQ
Common questions about solar maintenance
How often should solar panels be cleaned and serviced?
For most locations in India, panels should be cleaned every 4–6 weeks during dry and dusty seasons (October to May) and at least once during or after monsoon. A full system inspection including inverter, wiring, and structure should be carried out at least twice a year. In industrial or high-dust areas such as near highways or construction sites, monthly cleaning is recommended. Our AMC plans are designed around these frequencies for residential and commercial systems alike.
Can I clean solar panels myself?
While light panel cleaning with soft brushes is possible, professional cleaning achieves significantly better results — and more importantly, avoids risks. Using tap water leaves mineral deposits; hard brushes scratch anti-reflective coatings; accessing rooftop panels without proper safety equipment is a serious fall hazard. Professional cleaning uses demineralised water, specialist soft squeegees, and trained technicians with safety harnesses — protecting both your panels and your safety.
What does a solar AMC include?
Our Annual Maintenance Contracts cover scheduled panel cleaning visits, inverter health checks, electrical and structural inspection, performance monitoring, and service reports. Higher-tier plans add thermal imaging, remote SCADA monitoring, priority emergency response, and a dedicated service manager. All AMC plans use genuine spare parts and provide full documentation suitable for manufacturer warranty claims. See our AMC plans above for a complete breakdown by tier.
What is thermal imaging and why does my solar system need it?
Thermal imaging uses an infrared camera to detect heat anomalies in solar panels. Hotspot cells — caused by partial shading, cell cracks, bypass diode failure, or soiling patterns — heat up significantly while generating less power. Left unchecked, hotspots can permanently damage panels and in rare cases cause fires. Thermal imaging catches these faults years before they become visible or trigger complete module failure, allowing low-cost targeted replacement rather than expensive emergency repair.
My inverter is showing an error — what should I do?
Do not attempt to reset or open the inverter yourself. Note the error code displayed and call our service helpline — our technical team can often diagnose common inverter faults remotely and advise on whether it is safe to continue operating. AMC customers receive priority dispatch for inverter issues. Common causes include grid voltage fluctuations, overheating due to blocked ventilation, firmware issues, or internal component failure — all of which our technicians are trained to resolve on-site.
Does regular maintenance really make a financial difference?
Significantly. A 5 kW residential system generating ₹1,500/month in savings that loses 20% output to dust and minor faults is losing ₹300/month — or ₹3,600/year. An AMC plan costs ₹3,999–₹9,999/year and fully recovers that loss while also protecting your warranty and preventing expensive component failures. For commercial systems generating lakhs per year in savings, the ROI on maintenance is even more compelling. The cost of an AMC is almost always recovered within the first quarter of restored generation.
