Installing solar since 2017

A roof that pays you back.

We design your system around your usage, not around how many panels fit on the roof. We install it, connect it and handle the grant. And we'll tell you honestly when it isn't worth it.

What we do

A system that fits your usage

The most common mistake is oversizing. Surplus you export to the grid for next to nothing never comes back to you — so we design for your usage, not for the size of your roof.

Solar PV for your home

Designed around your annual usage and when you use it. We install, connect and notify ESB Networks — you don't have to deal with anything.

from €5,400

Battery storage

So you use in the evening what you generate during the day. Without a battery you use about a third of your output, with one about two thirds — and that's the whole difference in payback.

from €3,200

Solar PV for business premises

Businesses use electricity during the day, so they use almost everything they generate. Payback is usually quicker than for homes, and the system qualifies for capital allowances.

from €12,000

EV charging points

A wallbox connected to your solar system charges from your surplus first. Without it you charge your car from the grid even while the panels are generating.

from €640

Heat pumps

The best way to use your own electricity — the heat pump runs during the day too, when the panels generate most. We design it together with the solar system.

from €8,900

Grant and paperwork

The grant application, the approval, the ESB Networks notification, the connection paperwork and the completion certificate. We handle it all and hand it to you ready to sign.

Payback

How many years until it pays back

Enter your usage and your roof. You'll see the estimated output, the yearly savings and the year the investment pays back. And above all, how much of the output you actually use — that's what it all depends on.

You'll find it on your electricity bills. A typical house uses 3,000 – 5,000 kWh, and up to 9,000 with a heat pump.

When you use the most electricity at home

This matters more than system size. If you're out during the day, you use little of your own output — and that's where a battery helps.

Grant

How it works and where it most often goes wrong

Grant schemes change, but the rules tend to stay similar. These four things decide whether you get the grant and whether it's actually paid out.

Application first, then installation

This is the most common mistake. If you have the panels fitted before your grant is approved, you lose the grant — costs from before approval don't count.

the order matters

The grant offer expires

It's usually valid for eight months. If the installation and the claim aren't done by then, it lapses. So we plan the dates so it works out even if the supplier runs late.

we keep track for you

The installer has to be registered

Not every company is on the SEAI list of registered solar PV companies. If it isn't, your grant won't be paid — even if the installation is done properly. Check before you sign.

we're on the list

The grant doesn't cover everything

It's capped according to system size and doesn't apply to every part of the setup. So work out the full price and treat the grant as a discount, not as half the price.

How it works

Five steps from electricity bill to switch-on

Send us your bills

From a year of bills we can see your usage and how you spread it through the day. Without that a system can't be designed — only guessed.

We come for a site visit

We measure the roof and check the consumer unit and any shading. The survey is free even if nothing comes of it in the end.

You get a design and a price

With estimated output, savings and payback. If the payback comes out at over fifteen years, we'll say so and talk you out of it.

We handle the grant and permissions

The application, the approval and the ESB Networks notification. You sign, we do the running around.

We install and connect

Installation takes one to three days. Then certification, notification and switch-on — including an app where you can see your output in real time.

FAQ

What you ask us most often

Is solar PV worth it without a battery?

It depends on when you use electricity. If you're out during the day, you use about a third of your output and export the rest to the grid for a fraction of the price. That's when a battery makes sense. If you have a heat pump or a pool, or you work from home, it can work out well without one.

How long do panels last?

Manufacturers give a 25-year output warranty with a guaranteed drop of around 0.5% a year. The panels are the most reliable part of the system. The first thing to fail is usually the inverter — expect to replace it after twelve to fifteen years; it costs around €1,200.

What about winter and cloudy days?

It still generates, just less — in December about a tenth of what it does in June. That's why a system isn't designed to cover winter; that would mean a huge surplus in summer. The aim is to cover the annual balance, not every single day.

Will the installation damage my roof?

Not with proper fixings. We use hooks under the tiles or screws into the structure with special seals, and we give a ten-year guarantee against leaks on our work. If your roof is near the end of its life, we'll honestly recommend replacing it first.

Do I have to notify ESB Networks?

Yes — every system connected to the grid has to be notified and needs a completion certificate. We handle it all, including the connection paperwork. Without notification you risk being disconnected, and you can't be paid for exported surplus.

Do you also do off-grid systems for holiday homes?

Yes, for buildings without a grid connection. They're different setups — with a bigger battery and no link to the grid, so the grant doesn't apply. The payback isn't measured against your bills there, but against the cost of a grid connection, which can run to tens of thousands.
