Solar PV (photovoltaic) converts daylight into electricity. Panels on your roof generate power for your home or business, so you draw less from the grid, cut your bills and reduce your carbon footprint.
Solar panels absorb daylight and convert it into direct current (DC) electricity. An inverter then converts that into the alternating current (AC) used by your sockets, appliances and machinery.
Most homes in Dublin, Meath, Kildare and across Leinster are suitable. We check your roof condition, orientation, shading and your usage during a free site survey before recommending anything.
You save by generating your own electricity instead of buying it. The amount depends on your system size, your roof, and when you use power during the day — we model your actual consumption and show you realistic figures before you commit.
Very little. Panels are washed by rain and need the occasional clean if they get dirty. We recommend an annual inspection to check the fixings, cabling and inverter so the system keeps performing as expected.
No. A typical installation takes one to two days and most of the work happens on the roof and at the consumer unit. Power is off for short periods only, and we tidy up at the end of each day.
Yes. The SEAI Solar Electricity Grant covers domestic systems, the Non-Domestic Microgen Grant covers businesses and public bodies, and farmers can apply under TAMS 3. We prepare and submit the paperwork for you.
Yes. Panels work from daylight rather than heat, so they keep producing on overcast days — and cooler temperatures actually improve efficiency. Ireland's daylight hours suit modern PV systems well.
Quality systems are designed to last 25 years or more. Panels carry long performance warranties, and inverters and batteries carry their own manufacturer warranties, all of which we hand over with the paperwork.
Call us or send an enquiry for a free consultation. We'll talk through your options, carry out a site survey, and give you a fixed written quote with the grant you can claim spelled out.
Most pitched roofs in good condition are suitable. During the survey we check the covering, the structure beneath it, the orientation and any shading from trees or neighbouring buildings. South, east and west roofs all work well; flat roofs can be fitted with ballasted frames. If your roof needs work first, we'll say so before you commit to anything.
A standard residential array is installed in one to two days, including scaffolding. Adding a battery or EV charger usually keeps the job inside a week. Larger roofs, complex access or commercial projects are scoped individually after the survey.
We use an aluminium roof-rail mounting system with anchors suited to your roof type — tile, slate or profiled metal. The rails are fixed back to the structure, the panels clamp to the rails, and the array is held slightly off the roof surface so water still runs clear and cabling stays protected underneath.
It depends on the manufacturer, but panels are commonly warranted for 25 to 30 years on product and performance, inverters for 10 to 15 years, and batteries for around 10 years. We only supply kit we're happy to service, and you get the written warranty documents for every item we install.
A performance guarantee is a promise about how much electricity your panels will still be producing decades from now. It's what protects your investment if output falls faster than expected — so compare systems on the guaranteed output, the warranty term and the support behind it, not just the headline price.
Yes — that's what a battery does. During the day your system runs the house, charges the battery and exports any surplus. In the evening the battery discharges, so you're using your own solar power after dark instead of buying it from the supplier.
Yes. We supply and fit home and commercial battery storage, either as part of a new solar installation or added later to an existing system. Grid-charging batteries that top up on cheaper night rates are also an option where they make sense for your usage.
For most Irish roofs we fit monocrystalline panels, which give the highest output per square metre and perform well in diffuse light. Whether all-black, bifacial or higher-wattage panels suit you depends on your roof space, shading and budget, and we'll recommend the right option during the survey.
It depends on your system size, roof and usage pattern. As a rough guide, a 4kWp array in Ireland might generate in the region of 3,500 to 4,000 kWh a year, while an average home uses something similar — but what matters is matching generation to when you actually use power. We compare your meter readings against a proposed system before you buy.
Yes — full and partial rewires. A full rewire means lifting floors and chasing into walls, so we work room by room where it suits you, protect what's staying, and clean up at the end of each day. Plenty of older homes only need part of the installation replaced, and we'll tell you which parts.
If your board still uses rewireable fuses, has no RCD or RCBO protection, or shows signs of heat damage or outdated wiring, it's time for an upgrade. A modern board with individual RCBOs also means one fault doesn't take out the whole house.
Most homes are. We check that you have a dedicated circuit, adequate earthing and spare capacity at the board. Where the board or incoming supply is marginal, we'll say so up front and quote for the upgrade alongside the charger — and remember the SEAI grant of €300 towards a home charge point.
Yes. We carry out inspection and certification for rental properties, along with any remedial works the report throws up, so you have current documentation to hand to your letting agent or tenant.
That's straightforward work — extra sockets, data points, external sockets, showers, lighting and smart controls. Small jobs are often booked in alongside larger work so you're not waiting for a separate visit.
There's no single fixed interval in law, but most commercial premises are inspected and tested every three to five years depending on how the building is used and how much wear the installation gets. High-risk or heavily used environments may need it more often. We'll tell you what's due.
Yes. You receive test results and certification for the work carried out — installation certification, periodic inspection reports and ETCI test certificates as applicable. Fire alarm and emergency lighting certification is issued after each annual service visit.
Yes. We regularly work evenings, weekends and outside trading hours so a shop, office, school or hotel doesn't have to close. We agree the schedule with you in advance and make the site secure before we leave.
Yes. We work directly with architects, engineers, builders and ESB Networks on new installations, refits and upgrades, from design through to connection and handover — so you're not stuck acting as the middleman.
Yes. We install, test and service fire alarms and emergency lighting and provide annual certification. We also maintain CCTV, intruder alarms and access control systems alongside the electrical installation.
Yes. Three-phase distribution, sub-mains, armoured supplies, trunking and cable tray are all standard work for us, along with single-phase circuits for offices and ancillary loads. If you need a new or upgraded supply we'll coordinate the application with ESB Networks.
We plan the isolation and sequencing before we arrive — temporary supplies where they're needed, work broken into stages, and the option of evening or weekend shifts. Most planned jobs are arranged so part of the plant keeps running while we work.
Yes. We schedule into planned shutdowns and maintenance windows and give you a work list we can realistically complete in that time. For emergency faults we attend, make safe first, and agree the permanent repair with you.
Yes — process control, automation and bespoke control panels, plus repairs and modifications to panels you already have. Where practical we integrate new equipment into the existing setup instead of replacing the lot.
Yes. Plant installations, machinery moves and additions, generator installations and temporary power for the move itself — then we make the permanent connection, test it and certify it.
Yes, but the installation has to be designed around those loads. Motors, pumps, slurry gear and grain dryers draw high starting currents, so we size the incoming supply, protection and cabling to suit, and keep your inverter and controls on a stable circuit. If you have a generator, we'll make sure the changeover arrangement is correct too.
Solar PV on farm buildings can qualify under the Solar Capital Investment Scheme, which covers 60% of your spend up to €90,000. Eligibility depends on your registration with the Department of Agriculture and the scheme conditions when you apply, so we'll check where you stand before you commit. Businesses, schools and community buildings can apply under the SEAI Non-Domestic Microgen Grant.
We design and install to the wiring rules for the space: correctly rated IP enclosures and fittings, proper RCD protection, and the right zoning for parlours, tank rooms, wash-down areas and outdoor points. That keeps the installation safe and makes inspection straightforward.
Yes — LED high-bay and strip lighting for sheds and houses, parlour lighting, yard and security lighting, with sensors and controls where they'll save money. We survey the space and recommend an arrangement that gives even light and keeps running costs down.
Usually, subject to a structural check of the roof. Older sheds and barns sometimes need purlins or roof sheeting sorted first, and we'll tell you that during the survey rather than after we've started. Ground-mounted arrays are an option where the roof isn't suitable.
