Solar System Health Check

Solar System Health Check

Most solar systems in Ireland have never been looked at since the day they were commissioned. No service, no inspection, no performance check — just an assumption that the box on the wall is doing what the brochure promised. For a piece of electrical plant that lives on your roof in Irish weather and is supposed to earn its keep for 25 years, that’s a strange way to treat it.

The Solar Support Health Check is a complete physical, electrical and performance inspection of your system — with a written, photographed report telling you exactly what condition it’s in, what it should be generating for its size and location, what it actually is generating, and what (if anything) needs attention, ranked by urgency. It turns ‘I think it’s working’ into numbers.

When a Health Check Makes Sense

What the Health Check Covers

1
Panel condition — cracks, hot spots, delamination, browning, soiling and lichen. Mounting and fixing integrity, rail corrosion, cable management and UV degradation, bird and pest damage, roof penetrations and flashings. Coastal systems get particular attention to salt corrosion on fixings and connectors.
2
String open-circuit voltages and operating currents, string-to-string comparison, insulation resistance testing, earth continuity, DC isolator condition (the most failure-prone component on Irish boom-era installs), AC protection and RCD operation, and connection integrity — tested in line with IS 10101:2020.
3
Actual generation measured against expected yield for your array size, orientation, pitch and county — using realistic Irish irradiance figures, not brochure numbers. Inverter efficiency and event-log review, monitoring data history analysis, and battery state-of-health, charge/discharge behaviour and tariff scheduling where a battery is fitted.
4
ESB Networks notification status (NC6/NC7), MPRN export registration, Clean Export Guarantee status on your electricity account, smart-meter export recording, and SEAI documentation review. This is where we regularly find systems that have been quietly exporting to the grid for free since the day they were switched on.

What you receive

A written condition report with photographs; a defect list prioritised into safety, performance and cosmetic items; fixed-price quotes for any remedial work (no obligation — the report is yours to use with anyone); and a generation benchmark to measure every future year against.

The Payback Question, Answered With Data

A solar system quietly running 30% down doesn’t announce itself. It just shows up as electricity bills that never fell as far as promised — and most owners write that off as ‘the weather’ or ‘prices going up’. Meanwhile the true cause sits on the roof: a lazy string, a derating inverter, or an export registration that never happened.


The health check replaces that guesswork with a baseline. Once you know what your system should produce and what it does produce, every future year takes thirty seconds to verify — and any decline gets caught at a year old instead of at five.

Pricing

Standard domestic health check: €PRICE, fixed. Larger domestic and commercial systems quoted by system size. The health check is included free in year one of the Care Plan — for most owners the sensible route is health check first, Care Plan after.

Frequently Asked Questions

How long does it take?

Around 1.5–2 hours on site for a typical domestic system, with the written report delivered within TURNAROUND PLACEHOLDER working days.

I've just bought a house with solar and have no paperwork at all. Is that a problem?

No — it's one of the most common situations we see. We can assess and fully document a system from scratch: what's installed, its condition, its output, and its compliance status. We'll also transfer the monitoring and export registration into your name.

Can you check the battery too?

Yes. Where a battery is fitted we check its state of health, charge and discharge behaviour, and whether its scheduling actually matches your electricity tariff — a badly scheduled battery on an Irish smart tariff can be costing you money every single night.

Is this the same as an annual service?

The health check is the deep-dive baseline; the annual service maintains it. Most customers do the health check first, then move onto scheduled maintenance through the Care Plan.

Will you try to sell me repairs I don't need?

The report separates defects into safety, performance and cosmetic — with honest commentary on which are worth fixing and which aren't. We don't install systems and we publish our prices; the report is designed to be taken to anyone, which keeps us honest.
