Find the fault. Fix the system. Restore confidence.
From inverter faults and falling generation to damaged panels, monitoring failures and difficult roof inspections, Mr Solar provides methodical diagnosis and practical repair support across Norfolk and Suffolk.
Not every solar fault needs a new system.
A poor generation graph, inverter warning or unexplained electricity-bill increase can have several causes. We inspect the installation, review available monitoring and test the relevant equipment before recommending work.
Performance problems
Unexpectedly low generation, intermittent output, shading changes, meter issues and monitoring data that no longer looks right.
Equipment faults
Inverter error codes, failed isolators, communication faults, damaged cabling, defective optimisers or components that have reached end of life.
Roof and panel concerns
Storm damage, loose or broken panels, bird-related damage, suspected water ingress and installations that are difficult to inspect safely from the roof.
A clear diagnosis and an honest route forward.
Where repair is safe and economical, we will explain the work required. If equipment needs replacement, we look at compatibility with the existing array, meters, monitoring and any battery storage before specifying an alternative.
- System health checks and fault finding
- Inverter replacement and recommissioning
- DC and AC electrical testing
- Monitoring, Wi-Fi and data-logger support
- Drone-assisted visual inspections
- Documentation of findings and recommended action
From first symptoms to a working system.
Listen
We gather error codes, monitoring screenshots, system age and the history of the problem.
Inspect
We assess the equipment, installation and roof condition using suitable access or drone inspection where appropriate.
Test
Relevant electrical and performance checks help separate the symptom from the underlying cause.
Resolve
We explain the findings, costs and repair or replacement options before work proceeds.
