Your monitoring data, actually read

We install glass-glass panels — glass on both faces rather than a plastic backsheet — which carry a 30-year warranty. The inverters and batteries we fit are warranted for 10 years or more, and an inverter should still be expected to need replacement at least once over the life of the system. Your quote names the exact equipment and its exact warranty terms.

They need very little, but "very little" is 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 so faults are caught early are what 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.

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.

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.

Yes. Solar PV responds to daylight, not heat or direct sunshine, so panels generate on bright overcast days as well as clear ones. Output is strongly seasonal in Ireland — summer generation is far higher than winter — which is why we size a system around your year-round consumption pattern rather than a headline figure.

Most domestic rooftop installations in Ireland fall under planning exemptions, and exemptions for rooftop solar have been broadened considerably in recent years. Exemptions carry conditions, and some buildings — protected structures and certain locations in particular — are treated differently. We confirm the position for your specific property at survey stage and tell you plainly if permission is needed.

A typical domestic installation is completed in a small number of days on site once the system is designed, the grant offer is in place and materials are scheduled. Commercial and farm projects run longer and are phased around your operations. We give you a specific timeline in your quotation rather than a generic estimate.
