Going Solar: A Complete Guide for Homeowners

(Part 2 or 2)

Your Solar Panels Are Installed. Now What?

The workers have left. The panels are catching the sun, the inverter is humming, and electricity is quietly making its way into your home.

Today is day one of your free power.

But your solar journey doesn’t end when the installation team packs up. There’s still plenty to keep an eye on – from how much electricity your system generates to the cleanliness of your panels, the health of your inverter, and what happens when something goes wrong.

A little attention now can help your system perform reliably for years to come. Here’s how to look after your solar investment once the installation is complete.

Your First Job: Understand the System You Own

Once the installation is complete, don’t simply accept the keys and wait for your next electricity bill. Take time to understand what has been installed, how it works, and what you need to do if you encounter a problem.

Your installer should walk you through the system and provide the essential documents before closing the project.

You don’t need to handle electrical components yourself (in fact, you shouldn’t!). But you should know where they are, what they do, and which parts require professional assistance.

Is Your Solar System Producing What It Should?

Your solar panels may be working silently on the roof, but you shouldn’t have to wait until the next electricity bill to find out whether they’re performing properly.

Your installer should provide access to a monitoring app or inverter display. This is your first tool for understanding how much electricity your system is generating and identifying unusual changes.

The Numbers You Should Know

What to check

What it tells you

Daily generation

How many units your system produced today

Monthly generation

How much electricity it generated this month

Current power output

How much electricity it is producing right now

System alerts

Whether the inverter has detected a problem

Grid export

How much surplus electricity is being sent to the grid, where applicable

Generation will naturally vary with sunlight, weather, season, shading, and household conditions. A cloudy day doesn’t necessarily indicate a fault. What matters is identifying a sustained or unexplained drop in generation. For example, if your system produced similar amounts of electricity over several sunny days but suddenly generates very little, check the monitoring app for alerts and contact your installer if the issue persists.

Understand Your Electricity Bill and Net Meter

Going solar doesn’t automatically mean your electricity bill will become zero. Your bill depends on how much electricity your home consumes, how much your solar system generates, and how your DISCOM accounts for electricity imported from and exported to the grid. It also includes applicable tariffs, surcharges, and the settlement rules followed by your DISCOM.

Understanding this process will help you identify billing errors and avoid confusing a higher bill with a system failure.

What to Check on Your First Bills

After commissioning and net-meter installation, check:

  • Whether the meter records imports and exports correctly, where applicable.
  • Whether the solar installation is reflected in your electricity account.
  • Whether the bill includes unexpected charges or adjustments.
  • Whether your billing arrangement matches what was explained during installation.

Your electricity bill is not just a payment document. It is one of the ways you can check whether your solar system and grid connection are working together as expected.

Keep Your Panels and Equipment in Good Condition

Solar panels are designed to work outdoors for years, but they are still exposed to dust, pollution, bird droppings, rain, and extreme weather. Looking after your system involves more than cleaning the panels. You also need to pay attention to the inverter, wiring, mounting structures, and the area around the equipment.

The goal isn’t to inspect every component yourself. It’s to notice visible changes, follow the recommended maintenance schedule, and arrange professional checks when needed.

How Often Should You Clean Your Panels?

We recommend that you clean your panels at least once a month and, at the very least, once a quarter, as it can affect your power generation. Your location, roof conditions, pollution levels, and bird activity all make a difference. You may need more frequent cleaning if your home is:

  • Near a busy road or construction site.
  • In a particularly dusty environment.
  • Surrounded by trees or exposed to bird droppings.
  • Located in an area with limited rainfall.

Use clean water and a soft, non-abrasive cleaning method recommended by your installer. Avoid harsh chemicals, abrasive brushes, and aggressive scrubbing. Never put yourself at risk to clean a rooftop. If the panels are difficult to access, arrange professional cleaning instead of climbing onto a slippery or elevated roof. Always switch off the system before cleaning it!

Your Inverter Deserves Attention Too

The panels may be the most visible part of your solar system, but the inverter plays a critical role. It converts the electricity generated by your panels into electricity your home can use and, where applicable, export to the grid.


Most inverters come with apps, so be sure to download them and remotely monitor your generation and alerts. If there’s an issue, you must ask your EPC provider for help.

What Can You Check Safely?

You can carry out simple visual checks without opening the equipment:

  • Is the inverter displaying its normal operating status?
  • Are there persistent warning messages?
  • Is it installed in a covered, dry, and adequately ventilated location?
  • Are ventilation openings blocked by dust or stored objects?
  • Is there visible damage, moisture, or overheating?
  • Do cables and protective enclosures appear intact?

Maintenance guidance recommends keeping inverters dry and ventilated and periodically checking associated cables, breakers, and protection equipment.

If you notice a burning smell, unusual sounds, visible damage, or repeated shutdowns, don’t attempt to fix the issue yourself. Contact your installer or a qualified technician.

Frequency

What to do

Regularly

Check the monitoring app for unusual changes or alerts

Monthly

Review generation and compare it with previous months

As needed or monthly

Clean panels based on dust, pollution, and local conditions

Periodically

Look for visible damage, new shading, and blocked ventilation

After severe weather

Arrange a professional inspection if damage is suspected

Schedule servicing and electrical checks

Also keep an eye on changes around your system. A growing tree, nearby construction, roof repairs, or objects placed near the inverter can affect performance or access.

The best solar care routine is simple: monitor performance, notice changes, follow safety precautions, and get professional help when you need it.

Contact Your EPC vendor or Installer If You Notice:

  • Repeated inverter faults or unexpected shutdowns.
  • A significant, unexplained drop in electricity generation.
  • Damaged panels, mounting structures, or visible wiring.
  • Water entering the inverter or electrical enclosures.
  • Unusual sounds, burning smells, or signs of overheating.
  • Loose or damaged cables.
  • Problems following a storm, lightning strike, or electrical surge.

Avoid touching damaged equipment or attempting to reset electrical components without professional guidance.

Understand What Your Maintenance Contract Covers

Some homeowners choose an annual maintenance contract (AMC) for routine inspections and servicing. Others prefer to contact their installer only when a problem occurs. The important thing is to know what support you have (whether your AMC coverage is basic or comprehensive) and what you will be charged for. 

Questions to Ask Before Signing an AMC

Question

Why it matters

How many inspections are included?

Clarifies the service frequency

Is panel cleaning included?

Prevents unexpected cleaning charges

Are electrical checks included?

Establishes what preventive work is covered

Are emergency visits included?

Helps you understand support during breakdowns

Are spare parts covered?

Separates service costs from replacement costs

Is labour included for warranty repairs?

Clarifies your potential out-of-pocket expenses

What is the response time?

Sets expectations when you report a fault

Read the terms carefully before paying for an additional service package. A contract that covers cleaning may not include inverter repairs, replacement parts, or damage caused by external events.

25 year solar asset lifecycle

Think Long-Term: Your Solar System Is a 25+ Year Investment

Your solar system is expected to work for many years, but its performance and costs will change over time. Panels may gradually lose output, the inverter may need replacement, and components may require servicing. Planning for these possibilities helps you avoid treating every future expense as an unexpected failure.

Keep These Long-Term Considerations in Mind

  • Panel performance: Solar panels generally experience gradual degradation over their operating life.
  • Inverter replacement: The inverter will need replacement before the panels. The usual life of an inverter is less than 10 years.
  • Electrical servicing: Protection equipment, cables, and connections may require inspection.
  • Roof changes: Repairs, waterproofing, or construction may affect the solar installation.
  • Warranty expiry: Keep track of when coverage ends and what support remains available.
  • System expansion: If your electricity needs increase, check whether the existing system can accommodate additional capacity.

The system you install today may need to adapt to changes in your household over the years. Keep its documentation accessible, maintain a record of service work, and review its performance periodically.

Common solar faults

Solar Faults: Common Problems and What to Do

Most solar system problems don’t require homeowners to diagnose or repair equipment themselves. What matters is recognising the warning signs, understanding what might be causing them, and knowing when to contact your installer.

The table below focuses on common issues in residential rooftop solar systems. The same symptoms can have different causes depending on your system, inverter, wiring, and local grid conditions.

Common problem

What you may notice

Possible cause

What to do

No power generation

The monitoring app shows zero output

Grid outage, inverter shutdown, fault, or insufficient sunlight

Check the app and inverter display. Contact your installer if the issue persists.

Low electricity generation

Output is lower than expected

Dust, shading, equipment fault, damaged wiring, or inverter issue

Compare generation with previous days. Arrange professional inspection if the drop is unexplained.

Inverter keeps shutting down

The system stops and restarts repeatedly

Grid fluctuations, overheating, or internal fault

Record the timing and error code. Ask the installer to investigate.

Grid fault / overvoltage

Inverter disconnects, particularly during sunny afternoons

Grid voltage outside the inverter’s permitted range

Contact your installer or DISCOM. Don’t repeatedly reset the system.

Inverter overheating

Output falls during hot hours or a temperature warning appears

Poor ventilation, high ambient temperature, or blocked airflow

Check for visible obstructions around the inverter. Arrange a professional inspection.

Earth / insulation fault

ISO, insulation, or ground fault warning

Damaged cable insulation, moisture, or faulty connectors

Treat it as a safety issue. Do not restart or handle wiring; contact a qualified technician.

Monitoring app is offline

The system generates power but app data is missing

Wi-Fi, internet, communication device, or monitoring platform issue

Check whether your home internet is working. Contact the installer if system data remains unavailable.

Circuit breaker trips

A breaker switches off or the system stops unexpectedly

Electrical fault, overload, damaged equipment, or grid issue

Don’t repeatedly switch it back on. Contact a qualified electrician or installer.

Panel damage

Cracks, discolouration, or visible damage

Hail, impact, installation damage, or ageing

Avoid touching the panel or wiring. Arrange a professional inspection.

Water ingress

Moisture or corrosion around equipment

Poor sealing, damaged enclosure, or cable entry issue

Keep away from affected equipment and request urgent technical inspection.

Generation drops after roof work

Output changes after repairs or construction

Shading, moved panels, damaged cables, or altered connections

Inform your solar installer and arrange a post-work inspection.

There is no universal fault-code system across all inverter brands. The same type of problem may appear under different codes or descriptions, so always refer to your specific inverter’s manual and share the exact code with your installer.

What Homeowners Should Never Do

  • Open the inverter or electrical enclosures.
  • Disconnect solar cables or connectors.
  • Touch damaged or exposed wiring.
  • Attempt to repair an earth fault.
  • Climb onto the roof during unsafe conditions.
  • Repeatedly reset an inverter that is showing a persistent fault.

The golden rule: if the fault involves electricity, heat, damaged equipment, or exposed wiring, don’t experiment. Contact your installer.

Conclusion

Going solar is a long-term decision. Choosing the right system and getting it installed correctly is an important first step, but monitoring its performance, understanding your bills, following safety precautions, and knowing when to call for help are what keep that investment working for you.

You don’t need to become a solar expert. You simply need the right information, a little regular attention, and an installer who stands by the system long after the installation is complete.
