Peace of mind

Small issues rarely announce themselves

Many solar systems continue operating even when performance has fallen or a minor defect is developing. The first sign may be a higher bill, a warning in the app—or no obvious warning at all.

Our health check gives you a clear picture of the system today and identifies concerns before they become more disruptive or expensive.

Safety first

A structured review of the visible electrical installation, protective equipment and system condition.

Performance clarity

We compare generation and operating information to identify signs of underperformance.

Plain-English report

You receive written findings, supporting observations and clearly prioritised recommendations.

What we examine

A thorough review from panels to consumer unit

The scope is adapted to the installation, access and available documentation. Testing is undertaken safely and proportionately.

01

System performance

Generation reviewed against the system size, orientation and available records.

02

Solar PV modules

Visual condition, secure mounting and signs of damage, shading, soiling or hotspots.

03

DC electrical side

String voltage, current where appropriate, cabling, connectors and DC isolation.

04

Inverter operation

Status, fault history, ventilation, monitoring and expected operating behaviour.

05

AC electrical side

AC isolation, protective devices, consumer-unit connection and visible switchgear.

06

Earthing & labelling

Visible bonding, earthing arrangements, warning labels and emergency information.

07

Meters & monitoring

Generation meter, smart monitoring and consistency of recorded performance.

08

Installation condition

Signs of wear, water ingress, overheating, loose equipment or previous alterations.

MIS
3002

Reviewed with recognised solar PV installation requirements in mind

MIS 3002 is the MCS Solar PV Installation Standard. A health check is an assessment of an existing system; it does not retrospectively certify or re-certify the original installation.

THERMAL ANOMALY

Optional advanced inspection

Drone and thermal imaging for hard-to-see faults

For suitable domestic, commercial and larger solar arrays, a drone-assisted thermal inspection can help identify temperature anomalies consistent with defective cells, connection problems, shading effects or bypass-diode issues.

  • Rapid review of large or inaccessible arrays
  • Thermal and high-resolution visual evidence
  • Helps target further electrical investigation
  • Useful supporting records for asset management and insurers

CAA-compliant flight planning

Every flight is assessed against current UK drone rules. Where the proposed operation falls within the Specific Category, the required CAA Operational Authorisation and operating conditions apply.

A simple process

What happens during your health check

1

BEFORE THE VISIT

Tell us about the system

We gather the age, equipment details, known concerns and any monitoring information available.

2

ON SITE

Careful assessment

Our specialist completes the agreed performance, condition and safety checks with minimal disruption.

3

AFTER THE CHECK

Clear findings

You receive a written summary, friendly explanation and prioritised options if attention is recommended.

Who it helps

Reassurance for homes, landlords and businesses

Whether the installation is new to you, no longer supported by its original installer or simply due a professional review, we help you understand its true condition.

Frequently asked questions

Useful answers before you book

Will you tell me if nothing is wrong?+

Yes. Many visits end with reassurance that the system is operating normally, supported by a clear written explanation of what was checked.

Is this suitable for an older solar system?+

Yes. Older systems can benefit most, particularly where monitoring has stopped, the original installer is unavailable or performance history is unclear.

Do you carry out repairs?+

We assess first. If work is recommended, we explain the reason, urgency and options clearly. There is no obligation to instruct us.

Is this an electrical safety inspection?+

Safety forms an important part of the health check. The exact scope and limitations are stated in your report. Where a formal EICR or specialist investigation is required, we will advise you.
