Electrical & Solar AMC Guide: What It Covers, Checklists & Types

Maintenance & AMC

An annual maintenance contract (AMC) is an agreement for scheduled preventive maintenance of your electrical and allied systems, with defined visits, checks and support for breakdowns through the year. Instead of calling an electrician only when something fails, the system is inspected, cleaned and tested on a fixed schedule so problems are caught early.

This guide explains what an AMC typically covers, gives a practical checklist for each system — electrical panels and wiring, solar, CCTV, fire alarm, DG sets and earthing — suggests how often each should be serviced, and compares comprehensive and non-comprehensive AMCs so you can choose the right one for your home, society, shop or factory.

What does an AMC cover?

An AMC covers scheduled preventive maintenance visits plus breakdown support for the systems listed in the contract, for a fixed period — usually one year.

A typical contract defines the systems and equipment covered, the number and frequency of preventive visits, the checklist followed on each visit, how breakdown calls are raised and handled, whether spare parts are included, and what reports are provided. Clearly listing the equipment — number of panels, solar capacity, cameras, detectors, DG rating, earth pits — avoids disputes later.

Comprehensive vs non-comprehensive AMC

A comprehensive AMC includes the cost of most replacement parts, while a non-comprehensive AMC covers labour and service only, with parts charged separately.

Comprehensive contracts cost more upfront but make the annual budget predictable, which suits commercial buildings, societies and critical sites. Non-comprehensive contracts are cheaper and suit newer systems that are still under manufacturer warranty or where breakdowns are rare. Even comprehensive AMCs usually exclude major items such as complete panel replacement, damage from misuse, and natural calamities — read the exclusions carefully.

Electrical panels and wiring checklist

Electrical maintenance focuses on loose connections, overheating and protection devices, which are behind most electrical fires and failures.

  • Tighten terminals in main panels, DBs and busbars
  • Thermal scanning of panels to find hot spots (for commercial sites)
  • Test MCBs, MCCBs and RCCBs, including the RCCB test button
  • Check cable insulation, lugs and signs of heating or discolouration
  • Measure voltage, current and load balance across phases
  • Clean dust from panels and check enclosures, doors and gland plates
  • Check capacitor banks and power factor where installed

Solar power system checklist

Solar maintenance is mainly about keeping panels clean and confirming that output matches what the system should produce.

Dust in the Tricity's dry months and after construction activity can noticeably reduce generation, so panels are commonly cleaned every two to four weeks, using clean water and soft tools — never harsh chemicals or high-pressure jets. Service visits should also compare generation with expected values, check the inverter for error logs, inspect DC connectors and cables for damage or rodent bites, tighten mounting structure bolts, check the ACDB and DCDB, surge protection devices and the solar earth pits and lightning arrester.

CCTV and fire alarm checklist

CCTV AMC keeps every camera recording and viewable; fire alarm AMC confirms the system will actually raise the alarm in a fire.

For CCTV: clean camera lenses and housings, check focus and night vision, verify that the NVR/DVR is recording and hard disk health and retention days are as expected, check power supplies, cables and connectors, and confirm remote viewing works. For fire alarms: test detectors and manual call points, check the control panel for faults, test sounders and hooters, check battery backup and replace ageing batteries, and record everything in a log book. Fire detection and alarm systems in India are generally designed and maintained with reference to IS 2189, and the local fire authority may require maintenance records during inspections.

DG set and earthing checklist

A DG set must be serviced by running hours as well as on a calendar schedule, and earthing must be tested at least once a year.

DG maintenance includes checking engine oil, coolant, fuel and filters, battery condition and charging, belts and hoses, the exhaust, and a periodic test run on load, with oil and filter changes at the manufacturer's recommended hours. The changeover or AMF panel and its interlock should also be tested. Earthing maintenance means measuring the resistance of each earth pit with an earth tester, ideally in the dry season, checking connections at the pit and at the panels, watering conventional pits, and re-treating or adding pits if resistance has risen.

How often should maintenance be done?

Most systems need a preventive visit every quarter, with higher-use or critical systems checked monthly.

Frequency depends on the system's size, age and how critical it is. A home may be well served with quarterly visits, while a factory, hospital or commercial complex may need monthly checks of panels and DG sets and continuous monitoring of solar generation.

Benefits of an AMC

The main benefit of an AMC is fewer unexpected breakdowns, because faults are found and fixed while they are still small.

Regular maintenance also improves safety by catching loose connections and failed protection devices before they cause a fire or shock, keeps solar generation close to its potential, extends the life of expensive equipment, and gives you a written maintenance record that is useful for fire inspections, insurance and audits. A single point of contact for all systems also saves time for facility managers and society committees.

What to check before signing an AMC

  • A clear list of equipment and systems covered, with quantities and ratings
  • Number of preventive visits and the checklist used on each
  • How breakdown calls are logged and handled, including 24/7 emergency call-outs
  • Which spare parts are included and which are excluded
  • Service reports and test records provided after each visit
  • Contract period, renewal terms and payment schedule

Frequently asked questions

What is an AMC in electrical work?

An electrical AMC is an annual maintenance contract under which a contractor carries out scheduled preventive maintenance — tightening, testing and cleaning of panels, wiring and protection devices — and provides breakdown support for the covered systems for a year.

What is the difference between comprehensive and non-comprehensive AMC?

A comprehensive AMC includes most spare parts along with labour and visits, making annual costs predictable. A non-comprehensive AMC covers labour and service visits only, and any parts required are charged separately.

How often should solar panels be cleaned?

Solar panels are commonly cleaned every two to four weeks, and more often in dusty conditions or near construction. Use clean water and soft tools; avoid harsh chemicals and high-pressure jets that can damage the glass and coating.

How often should a fire alarm system be serviced?

A fire alarm system is typically serviced quarterly, with a full test of detectors, call points, sounders and batteries at least once a year. Results should be recorded in a log book for fire authority inspections.

Is an AMC worth it for a home?

For homes with solar, a DG set, CCTV or automation, an AMC is usually worthwhile because it keeps these systems performing, catches faults early and gives you a single contact for service. For a basic home electrical setup, an annual safety check may be enough.

Does an AMC include earthing testing?

A good electrical or solar AMC should include measuring the resistance of each earth pit at least once a year, checking connections, and recommending re-treatment or additional pits if resistance has risen.
