Solar questions, answered straight

Winter output, grants, planning, batteries and payment: the honest answers.

Do solar panels work in a Dublin winter?

Yes, but a lot less. Solar runs on daylight, so panels still generate on bright overcast days. From November to January, though, the days are short and the sun is low, and on a dull December day output can be close to nothing. Most of a system's yearly generation comes between spring and early autumn. That's why we show you an estimate for every month, not just a yearly total. A diverter or battery helps you use more of what you do generate.

How much is the SEAI grant?

SEAI sets the amount based on system size. SEAI's page states that the maximum domestic solar PV grant is €1,800 and that it will remain at €1,800 in 2026 (checked 26 Sep 2026). Eligibility rules apply: for example, the home must have been built and occupied before 2025 (SEAI, checked 6 Oct 2026). You must have SEAI approval before any work starts. Always check SEAI's page for the current figures:

How much will I save?

We won't give you a headline saving or payback figure, because it depends on your usage pattern, your tariff, how much you use yourself versus export, and future electricity prices. What we will do is model your likely generation and self-consumption from your own usage data and show you the assumptions, so you can judge for yourself.

Do I need planning permission?

Often not for rooftop solar on a house, but the exemptions have conditions, for example protected structures, Architectural Conservation Areas and distance from roof edges. Different rules apply to non-house buildings, including near airports. We check your situation before quoting. Government guidance:

Do I need a battery?

Not always. If most of your use is in the evening, a battery usually earns its place. If you're home by day or have a hot-water cylinder, a diverter may soak up the surplus first, and a battery can be added later. We'll run your usage both ways.

My roof faces east/west. Is it worth it?

It can be. South-facing roofs generate the most, but east/west roofs spread generation across morning and evening, which suits many households. We'll show you the estimate for your roof either way. North-facing roofs are usually not worth it, and we'll tell you if that's the case.

What happens to electricity I don't use?

Surplus electricity is exported to the grid, and your electricity supplier pays you for it under the Clean Export Guarantee. Rates vary by supplier and change, so check your supplier's current rate. A diverter or battery lets you keep more of your own generation.

How long does installation take?

It depends on the system and the house. [FACT NEEDED: typical install duration and lead time from grant approval.] One ground-mount customer wrote that the team 'were finished in 1 day'.

What warranties do I get?

[FACT NEEDED: panel product/performance, inverter, battery and workmanship warranty terms, in writing.]

Do you handle the paperwork?

Yes, our side of it. We notify ESB Networks and provide the certificates and documents you need for your SEAI grant claim. You make the grant application to SEAI yourself (we'll walk you through it), and you'll also need a post-works BER.

Can you fix or add to a system someone else installed?

[FACT NEEDED: do you take on repairs, health checks or battery add-ons for other installers' systems?]

How does payment work?

Homes: 50% deposit, 50% on completion. On grant-aided jobs, the deposit is due two weeks before your install date. Business jobs: staged payments, 25% / 50% / 25%. All terms are set out in your written quote.
