Solar panels are built to last, but that doesn’t mean they should be left unchecked. Like many other systems, it goes through a lot of wear and tear. But, this can often be hard to notice, which is why solar PV health checks are needed.
But, few people know what happens in solar panel inspection, what’s included, or other factors. Let’s dive in.
Why Regular Solar PV Health Checks Matter
Most solar PV systems operate quietly in the background, so it’s natural to assume everything’s working like it should. But, this isn’t always the case. Performance degrades slowly, and this can often be difficult to notice.
Problems can develop beneath the surface, but routine inspections can help you find and address them early. Instead of waiting for something to go wrong, solar PV health checks proactively prevent them.
What Does a Solar PV Health Check Include?
A professional inspection looks at the entire solar PV system instead of focusing just on individual components. At ServiceMy, the process is designed to provide homeowners with a detailed understanding of how their system is performing and what, if anything, needs attention.
This involves a few specific steps.
Visual Inspections of the Solar Panels
The inspection begins with a thorough assessment of the panels themselves. The engineers look for signs of:
- Cracked or damaged panels
- Surface deterioration
- Loose mounting brackets
- Storm damage
- Dirt, moss, or debris affecting performance
- Visible cable damage
Even minor damage can reduce energy production or let moisture into the system over time, both of which can eventually become larger problems.
Inverter Performance Checks
The inverter is one of the more important components in any solar PV installation. It converts the direct current (DC) generated by your panels into usable alternating current (AC) for your home. If the inverter isn’t working properly, your entire system can lose efficiency.
During the inspection, engineers check:
- Operating status
- Error codes
- Performance history
- Electrical output
- General condition
- Ventilation and cooling
Many hidden performance issues start with the inverter instead of the panels themselves.
Electrical Safety Testing
Solar PV systems operate using high-voltage electricity, making regular safety testing essential. A professional inspection includes checks of:
- Electrical connections
- Wiring condition
- Isolation switches
- Earthing arrangements
- Protective devices
- Signs of overheating or corrosion
These tests make sure your installation keeps operating safely while reducing the risks of electrical faults.
Drone Thermography Detects Hidden Problems
One of the biggest differences between a basic inspection and a comprehensive professional assessment is the use of drone thermography solar technology. Thermal imaging lets engineers detect heat patterns across every panel without climbing onto the roof.
Using specialist infrared cameras mounted on drones, hidden faults that can’t be identified during a normal inspection become visible. This can reveal:
- Hot spots
- Damaged cells
- Faulty electrical connections
- Internal panel defects
- Areas producing less power than expected
Many of these issues develop internally and remain invisible until they affect overall system performance. Because inspections are carried out remotely, drone surveys are also safer and let engineers assess difficult-to-access roofs more efficiently.
Solar Panel Efficiency Analysis
Generating electricity isn’t the same as generating the amount of electricity your system should be producing. That’s why professional inspections include a detailed efficiency assessment.
Instead of just confirming the system is operational, engineers compare actual performance versus expected output based on factors like:
- System size
- Panel orientation
- Age of installation
- Seasonal conditions
- Historical generation data
If production is lower than expected, further investigation can find the underlying cause. This type of analysis offers a much clearer picture of your system’s overall health than simply checking whether the inverter is switched on.
Solar Battery Inspection (Where Appropriate)
If your system includes battery storage, the battery also needs routine servicing. A dedicated solar battery inspection checks that your battery continues storing and delivering electricity safely and efficiently.
These battery inspections typically include:
- Battery condition assessment
- Charge and discharge performance
- Capacity testing
- Battery management system checks
- Electrical connection testing
- Firmware updates, where applicable
As battery storage becomes more common, including it in your annual inspection helps maximise the value of your entire system.
Your Personalised Maintenance Report
One of the most valuable parts of a professional inspection is the report you receive afterwards. Instead of leaving you with just a ‘pass’ or ‘fail,’ ServiceMy provides a detailed overview explaining how your system is performing.
Your report should include:
- Inspection findings
- Thermal imaging results
- Efficiency analysis
- Identified faults
- Safety observations
- Recommended maintenance
- Suggested repairs, if needed
This lets you make informed decisions about any future maintenance instead of reacting after a fault develops.
Solar PV Health Check vs. Solar PV & Battery Health Check
Not every homeowner has battery storage, which is why ServiceMy offers inspections tailored to different systems.
Standard Solar PV Health Check
This service focuses on the solar generation system itself, including:
- Solar panel inspection
- Inverter testing
- Electrical safety tests
- Drone thermography
- Performance analysis
- Maintenance recommendations
It’s ideal for homeowners with a conventional solar PV installation.
Solar PV & Battery Health Check
If your home also includes battery storage, the inspection expands to include the battery system. On top of everything in a standard inspection, it includes:
- Battery health
- Storage performance
- Charging efficiency
- Battery management systems
- Battery safety
By inspecting both generation and storage together, homeowners gain a complete understanding of how their system is performing.
Why a Thorough Inspection is Worth it
A comprehensive inspection involves a lot more than a quick visual assessment, and serves as a proactive approach to looking after your system. This helps:
- Improve energy generation
- Identify hidden faults
- Reduce the need for expensive repairs
- Extend equipment lifespan
When compared to the cost of replacing expensive components, this could be the much better approach to take.
