Solar Panel Maintenance and AMC Services
Regular cleaning, electrical health checks and performance monitoring keep your solar investment generating close to its design output, year after year.
Protect Your Solar Investment Over the Long Term
Solar panels are largely low-maintenance, but they are not maintenance-free. Dust, pollen, bird droppings and general grime accumulate on panel surfaces and gradually reduce output if left unaddressed, while inverters and electrical connections benefit from periodic health checks to catch small issues before they become costly failures. Our maintenance services cover both existing installations from other vendors and systems we've installed ourselves, with structured Annual Maintenance Contracts (AMC) available for customers who want scheduled, worry-free upkeep rather than reactive service calls.
Who is this solution suitable for?
Key Benefits
Restored Performance
Regular cleaning removes the dust layer that silently reduces output.
Early Fault Detection
Electrical checks catch small issues before they escalate.
Warranty Claim Assistance
Support navigating manufacturer warranty processes when needed.
Scheduled, Predictable Visits
AMC plans remove the guesswork of when service is due.
How the System Works
- 1 We assess your existing system's condition, generation history (where available) and any specific concerns you've noticed.
- 2 A scheduled visit covers panel cleaning, connector and cable inspection, and inverter diagnostic checks.
- 3 Where monitoring hardware is present, we review performance data against expected generation for your system size.
- 4 Any faults, underperforming strings, or warranty-eligible issues are flagged with a clear recommendation.

Available System Capacity
Indicative starting points — final sizing depends on your actual consumption and rooftop or land area.
| System Capacity | Typically Suitable For | Approx. Area Required | Indicative Monthly Generation |
|---|---|---|---|
| Up to 5 kW | Residential rooftop systems | Cleaning + basic electrical check | Recommended 2–3 times/year |
| 5 kW – 25 kW | Larger homes, small commercial | Cleaning + inverter diagnostics | Recommended quarterly |
| 25 kW – 100 kW | Commercial and society installations | Full AMC with monitoring review | Recommended quarterly |
| 100 kW+ | Industrial and factory systems | Comprehensive AMC with performance-ratio tracking | Recommended monthly to quarterly |

What Affects Your Project Cost
- System size and number of cleaning/inspection visits required per year
- Site accessibility — rooftop height, terrain, and safety equipment needed
- Whether inverter servicing or component-level repairs are needed
- Presence of monitoring hardware for data-backed performance review
- Scope of AMC coverage selected (cleaning-only vs. comprehensive)
Estimated Savings Potential
A well-maintained system consistently outperforms a neglected one — even a modest dust-related output loss, left unaddressed for months, adds up to meaningful lost savings over a year. Regular maintenance is generally a small recurring cost relative to the generation it protects.

Calculate Your SavingsSubsidy Applicability
Maintenance services themselves are not covered under government subsidy schemes, which apply to the initial system installation. However, systems originally installed under a subsidy scheme may have specific warranty or upkeep conditions worth reviewing — we can help you check these during your first maintenance visit.

AMC plans are typically offered as an annual or multi-year service fee rather than a financed product, though bundled finance covering both installation and multi-year maintenance may be available depending on your original purchase arrangement.

Solar Maintenance — Frequently Asked Questions
This depends on your local dust levels and season — most residential systems benefit from cleaning 2 to 3 times a year, with more frequent cleaning recommended before and after the monsoon and dust-heavy months.
Yes, our maintenance and AMC services are vendor-agnostic and cover systems regardless of who originally installed them.
Scope varies by plan, but commonly includes scheduled panel cleaning, inverter diagnostics, cabling and connector inspection, and a performance review where monitoring data is available.
Panels are designed to withstand normal rain, wind and hail exposure within their rated specifications; however, we recommend a post-storm inspection after any severe weather event as a precaution.
Our team investigates the fault, determines whether it's a warranty-eligible component issue or a servicing need, and coordinates the appropriate repair or manufacturer claim.
Where monitoring hardware is installed, we can review generation data remotely to flag potential issues between scheduled visits — see our Solar Monitoring page for more detail.
Cost depends on system size, visit frequency and scope of coverage; we provide a specific quotation after assessing your system during the initial site visit.
Professional cleaning using appropriate methods does not affect standard manufacturer warranties; improper cleaning (abrasive materials, high-pressure water on damaged seals, etc.) could potentially cause issues, which is why professional service is recommended.
In many cases, yes — dust buildup, loose connections or minor inverter issues are common, addressable causes of underperformance identified during a maintenance visit.
