Get Your Solar System Working Properly Again

If your solar system has stopped working, is producing less electricity
than expected or is displaying a fault code, Mr Solar can investigate
the problem and recommend the right solution.

🔍

Fault Finding

Electrical testing and system diagnostics to identify the cause of
faults, shutdowns and reduced generation.

Inverter Replacement

Replacement of failed or obsolete solar inverters, including new
monitoring and warranty options.

🚁

Thermal Drone Surveys

Thermal inspections to help locate panel hotspots, module defects
and performance differences across an array.

🔋

Battery Upgrades

Add battery storage or upgrade to a modern hybrid system to make
better use of your solar generation.

📱

Monitoring Support

Help with offline apps, lost monitoring access, Wi-Fi connections
and system ownership transfers.

🛠️

Service and Maintenance

Testing, inspection and preventative maintenance for existing solar
PV and battery systems.

Common solar faults

Problems We Regularly Investigate

Your inverter may still appear to be operating even when part of the
system is underperforming. We investigate both complete failures and
less obvious performance problems.

!

No Solar Generation

The inverter is switched off, blank, in standby or no longer
producing usable electricity.

Error Codes

The inverter or battery is displaying a warning, alarm or recurring
fault message.

📉

Reduced Performance

Generation has suddenly dropped or the system is producing less
energy than expected.

📡

System Offline

The monitoring platform has stopped updating or the inverter has
lost its internet connection.

🔌

Wiring or String Faults

Suspected problems with solar strings, isolators, connectors,
cabling or electrical protection.

🔋

Battery Problems

Battery not charging, not discharging, showing communication errors
or failing to follow its schedule.

If something does not look right, do not ignore it.
Early investigation can reduce lost generation and help prevent a
smaller issue from becoming a more expensive repair.

Thermal imaging

Advanced Drone Thermal Inspections

Thermal imaging provides a fast and effective way to inspect large
or difficult-to-access solar arrays without immediately requiring
scaffolding.

  • Locate potential panel hotspots
  • Identify suspicious or underperforming modules
  • Compare performance across the solar array
  • Investigate possible string or connection problems
  • Inspect areas that are difficult to view from ground level
Reduce unnecessary access costs:
a drone survey can provide useful initial evidence before scaffolding
or roof access is arranged.

Repair or replace

Solar Inverter Faults and Replacements

The inverter is at the heart of your solar system. If it fails,
your panels may be producing little or no usable electricity.

We can assess whether repair, replacement or upgrading to a modern
hybrid inverter offers the best long-term value.

  • Inverter error-code investigation
  • DC and AC electrical testing
  • Replacement inverter installation
  • Monitoring and app setup
  • Hybrid and battery-ready upgrades
  • Up to a 10-year warranty on selected products
Indicative inverter replacement range:
approximately £500–£2,000 depending on capacity, specification,
compatibility and any corrective electrical work required.

Improve your system

Repair, Replace or Upgrade

A failed inverter may also provide an opportunity to modernise an
older system. We will explain the available options without
recommending unnecessary equipment.

  • Replace an obsolete or failed inverter
  • Upgrade to a modern hybrid inverter
  • Add solar battery storage
  • Improve monitoring and energy control
  • Prepare the property for EV charging
  • Use suitable off-peak and export tariffs

Recommendations are based on your existing equipment, electricity
use, solar array and future energy plans.

Straightforward support

How Our Repair Service Works

We keep the process clear so you understand what has been found and
what work is recommended.

1

Tell Us the Problem

Send us the inverter make, fault code, photographs and any available
monitoring information.

2

Initial Guidance

We review the information and provide initial telephone guidance
where possible.

3

Test and Inspect

If required, an engineer visits to inspect, test and diagnose the
solar system.

4

Repair or Upgrade

We explain the findings and provide a quotation for the recommended
corrective work.

Clear starting prices

Solar Diagnostic and Repair Options

Final pricing depends on the equipment, property location, access
requirements and nature of the fault.

Initial Telephone Guidance

Free

Initial guidance based on the fault code, photographs and system
information supplied.

Inverter Replacement

£500–£2,000

Indicative range depending on inverter capacity, compatibility,
warranty and installation requirements.

Prices are indicative and subject to inspection. Any refund or credit
against subsequent work must be confirmed when booking.

Original installer unavailable?

We Support Systems Installed by Other Companies

It does not matter who originally installed your solar panels. We
specialise in diagnosing, repairing and upgrading existing systems.

We regularly help customers whose original installer has retired,
ceased trading or is no longer responding.

  • Unsupported solar PV installations
  • Properties purchased with solar already installed
  • Lost monitoring or account access
  • Unknown equipment or system operation
  • Older systems requiring modernisation
Moved into a property with solar?
We can identify the equipment, check system operation, help restore
monitoring and explain how the system works.
