Maintenance & support

We install glass-glass panels, with glass on both faces rather than a plastic backsheet, and they carry a 30-year performance warranty. A performance warranty and a product warranty are two different things: the performance warranty covers the output over time, and the product warranty covers the panel itself. Your quote names both terms for the exact panel we are fitting. The inverters and batteries we fit are warranted for 10 years or more, and you should still expect an inverter to need replacement at least once over the life of the system.

Very little, but not none. Irish conditions bring moss, lichen, salt and agricultural dust, and soiling reduces output gradually enough that owners often do not notice. Periodic inspection, cleaning where needed, and monitoring that catches faults early will keep an array performing across its full life.

Usually yes, though it depends on your existing inverter and consumer unit. Some systems accept a battery directly, others need an additional AC-coupled unit. We can assess a system we did not install and tell you what is possible before you commit to anything.

A standard suburban roof often only needs attention every year or two. Farms, coastal properties, houses under trees and roofs with bird activity need it more often. The better guide is your monitoring data rather than the calendar: if output has slipped against the same months last year and the weather has not, soiling is the usual suspect. If your panels are visibly clean and producing on benchmark, we will tell you to keep your money.

The software does the part nobody keeps up by hand: weather-adjusted yield models, string comparison, fault-code history and degradation trends, run every week across every system we watch. The judgement about what to do with a flag stays with our engineers. The practical payoff is that when a visit is needed it is a targeted one. The analysis says which string or which component, rather than sending someone up for a general look.

Export payments come from your electricity supplier under the Clean Export Guarantee, not from the government. When we commission your system we notify ESB Networks (the NC6 or NC7 form), which is what registers you as a microgenerator; your supplier then applies its export rate to your account. With a smart meter your actual export is measured; rates vary by supplier, so it is worth comparing. The first €400 a year of export income is exempt from income tax, an exemption currently legislated to the end of 2028.

Solar PV normally improves a BER, because it reduces the calculated primary energy use of the home, and a post-works BER assessment is part of the SEAI grant process anyway. On insurance, tell your insurer you have added solar, as with any alteration to the building. Cover for panels is routine.
