Solar Panel Servicing: Myths, Facts & Maintenance Guide

With the rapid growth of rooftop and commercial solar installations in India, one question we hear very often is: “Do solar panels really need frequent servicing?”

Many people assume that once solar panels are installed, they will continue to work perfectly for 25 years without requiring much attention. While solar systems are definitely low-maintenance, the idea that they need no servicing at all is one of the biggest myths in the industry.

In this blog, S’unlimited Solar, a trusted solar EPC company in India, breaks down the myths vs facts around solar panel servicing so you can make informed decisions and protect your investment.

Why Solar Panel Servicing Is Often Misunderstood

Solar panels have no moving parts, which makes them far more reliable than many other power systems. This is why many installers oversell the idea of “maintenance-free solar.”

However, in real Indian conditions: dust, pollution, bird droppings, heat, monsoons, and voltage fluctuations, solar systems do require regular inspection and care to perform at their best.

This is where professional solar panel servicing and proper operation and maintenance of solar power plant play a critical role.

Myth 1: Solar Panels Don’t Need Any Servicing

Fact: Solar panels do not need frequent servicing, but they do need periodic servicing.

Dust accumulation alone can reduce power generation by 10–25% in many Indian cities. Over time, loose connections, inverter issues, and unnoticed faults can further reduce system efficiency.

Regular solar panel servicing helps:

• Maintain optimal power output
• Detect issues early
• Avoid sudden system breakdowns
• Protect long-term return on investment

A reliable solar EPC company will always recommend scheduled maintenance, not neglect.

Myth 2: Cleaning Panels Once Is Enough

Fact: One-time cleaning is not sufficient, especially in India.

In areas with:

• Heavy dust (Pune, Satara, Mumbai outskirts)
• Industrial pollution
• Construction activity
• Bird movement

Panels may require cleaning every 2–4 months, depending on the site.

A professional solar panel maintenance service uses safe cleaning methods that protect panel coating and avoid micro-cracks, something manual cleaning often damages.

Myth 3: Servicing Increases Solar Installation Cost Too Much

Fact: The solar installation cost does not significantly increase due to maintenance.

In reality:

• Annual maintenance cost is very small compared to the energy savings
• Poor maintenance leads to hidden losses in generation
• Timely servicing helps avoid costly inverter or component replacements

Think of solar panel servicing like regular servicing of a car, it improves performance and extends life, not adds unnecessary expense.

Myth 4: Inverters and Electrical Parts Don’t Need Checks

Fact: Inverters are the heart of any solar system and require regular monitoring.

Without proper operation and maintenance of solar power plant, issues like:

• Overheating
• DC/AC imbalance
• Loose wiring
• Earthing problems

can go unnoticed until major failure occurs.

A professional solar EPC company in India includes inverter health checks, performance analysis, and safety inspections as part of a complete solar panel maintenance service.

Myth 5: Servicing Is Only Needed for Large Solar Plants

Fact: Whether it’s a home rooftop system, housing society, or commercial solar plant, servicing is equally important.

Residential users often miss early signs of reduced generation because they don’t monitor data daily. Regular solar panel servicing ensures:

• Consistent output
• Accurate generation data
• Safe electrical operation

Even a 5 kW system benefits greatly from structured maintenance.
