How often should solar PV be serviced?
A periodic inspection every one to two years is typical for domestic systems, with commercial arrays often checked annually. Follow the manufacturer's and MCS guidance for the system.

Need a PV Service for your own property? It's issued by the tradesperson who does the work — TradePlanr is the app they use.
A solar PV service record documents the periodic inspection and maintenance of a solar PV array and any battery storage, confirming the system is safe, secure and generating as expected.
Periodic inspection of PV systems follows the approach in IEC 62446, covering the array, the d.c. and a.c. circuits, the inverter and the protective devices, while MCS guidance and manufacturer instructions set out what a maintenance visit should include for the panels and the battery.
TradePlanr lets you record the visual inspection, test results and generation data on site and produce a clear PDF service record, so the owner has evidence the system is being looked after.

When it's required
Solar PV systems should be inspected and serviced periodically, typically every one to two years for domestic systems and more often for commercial arrays, to catch loose fixings, damaged cables, failing isolators and underperformance early.
Battery storage adds its own checks, from state of health to charge settings and ventilation, and manufacturers expect maintenance in line with their instructions to keep warranties valid.
A dated service record also supports insurance, landlord obligations and resale, showing the system has been maintained by a competent person since it was commissioned.

Frequently asked questions
What tests are carried out on a PV system?
A service typically includes a visual inspection plus string open-circuit voltage, operating current and insulation resistance tests, following the periodic verification approach in IEC 62446.
Does battery storage need servicing too?
Yes. The visit checks the battery's state of health, charge settings, connections and ventilation in line with the manufacturer's instructions, and records any firmware or settings changes.
Can I complete the record on site?
Yes. TradePlanr lets you record the inspection, test results and generation data, capture the signature and produce the PDF at the property.
