Why a health check matters
A solar panel system health check protects the long‑term value of your investment by confirming that every component is performing as designed. Over time, shading, soiling, and component ageing can reduce output without obvious signs. Regular verification catches these drifts early, preventing small losses from becoming costly repairs.
What a health check covers
- Visual inspection of modules for cracks, delamination, or hot‑spot indicators.
- Electrical testing of string voltages and currents against design expectations.
- Inverter performance review, including firmware version and error‑log analysis.
- Wiring, connector, and isolation‑device integrity checks.
- Comparison of actual generation data with modelled yield for the site.
How it differs from routine cleaning
Cleaning removes surface debris; a health check evaluates the electrical and mechanical condition of the whole system. A clean array can still suffer from inverter faults, loose connections, or degraded bypass diodes. The health check therefore complements, rather than replaces, periodic cleaning.
When to schedule a check
Most owners benefit from an annual review, especially after the first year of operation and following severe weather events. Systems approaching the midpoint of their warranty period gain additional confidence from a mid‑life assessment. If you notice an unexplained dip in generation, a prompt check is advisable.
Our process
1. Remote data review – we analyse your monitoring portal to flag any performance anomalies. 2. On‑site inspection – a vetted, MCS‑certified partner visits to carry out the physical and electrical tests. 3. Detailed report – you receive a clear, engineering‑focused summary with prioritised recommendations. 4. Follow‑up support – any remedial work is quoted transparently and can be arranged through the same partner network.

Frequently Asked Questions
- An annual check is typical, with additional reviews after extreme weather or if you notice a sudden drop in output.
- No, the health check focuses on electrical and mechanical performance; cleaning can be scheduled separately if required.
- The inspection is non‑intrusive and carried out by MCS‑certified partners, so it does not invalidate manufacturer or workmanship warranties.
- You receive a prioritized report and a transparent quote for any remedial work, which can be completed by the same vetted installation partner.
