System Health Checks
Independent solar system health checks that measure real-world output against expected performance.
Why it matters
A solar array that drifts out of spec can silently erode the savings and energy independence that motivated the original install. An independent health check confirms the inverter is converting at its rated efficiency, that each string of panels is delivering the generation profile expected for the UK climate, and that wiring and mounting remain safe and compliant.
When a system under‑performs, the household may miss out on Smart Export Guarantee payments and could face higher grid imports than necessary. Regular verification also protects the long‑term asset value of the installation, supporting any future EPC uplift or resale appeal.
How it works
- 1 Desktop review – we gather the original design data, MCS certification details, and any monitoring portal access to build a baseline expectation for your site.
- 2 On‑site inspection – a qualified engineer checks inverter firmware, DC/AC wiring integrity, connector torque, and mounting hardware for corrosion or movement.
- 3 Performance test – using calibrated irradiance meters and a portable analyser, we measure real‑time string currents and voltages against the predicted yield for the current weather conditions.
- 4 Report & recommendations – you receive a concise PDF highlighting any deviations, safety concerns, and a prioritized action plan, including whether re‑certification is needed for SEG eligibility.
Is it right for you?
If you purchased a property with an existing array and have no documentation of the original commissioning, a health check fills the knowledge gap and ensures you are not inheriting hidden faults.
Homeowners who installed outside of a vetted network, or who have noticed a gradual drop in generation on their monitoring app, will benefit from an impartial assessment that is not tied to any specific installer’s warranty agenda.
Businesses with rooftop systems that must demonstrate ongoing compliance for sustainability reporting can use the report as evidence of due diligence.

Frequently asked questions
How do I know if my solar panels are underperforming?
Falling generation figures on your monitoring app, an unexplained rise in bills, or visible panel damage are common signs. A health check compares actual output against expected generation.
I bought a house with solar already installed — can you check it?
Yes. A system health check verifies the existing installation's condition, MCS documentation and performance, without needing the original installer.
