Frequently Asked Questions
Answers to common questions about solar panel installation in Ireland and how our service works.
About Our Service
What is SolarWise?
SolarWise is a free service that connects homeowners in Ireland with local solar panel installers. You tell us what you need, we match you with an installer, and they provide you with a quote.
Is it free?
Yes, completely free. You will never be charged by us. Installers pay to receive enquiries through our platform. That's how we keep the service free for you.
Do you install solar panels?
No. We're a matching service, not an installation company. We connect you with independent local installers. The quote, the equipment, and the installation are between you and the installer.
Is there any obligation after I submit a request?
None. You can review the quote and decide in your own time. If you choose not to go ahead, you don't need to do anything. There's no contract, no deposit, and we won't chase you up.
What areas do you cover?
All of Ireland, including Dublin, Cork, Galway, Limerick, Waterford, and everywhere in between.
Solar Panel Installation
How much do solar panels cost in Ireland?
For a typical home, you're looking at €5,000 to €12,000 before grants, depending on system size, panel type, and whether a battery is included. After the SEAI grant of up to €1,800, the net cost for most homes is between €4,000 and €10,000. The best way to get a real price is to request a free quote.
How long does solar installation take?
Most residential installations are completed in 1–2 days. The installer handles everything from scaffolding to connecting the system to your electricity meter. There's minimal disruption to your daily routine.
Will solar panels work on my roof?
Most Irish roofs are suitable. South-facing is ideal, but east and west-facing roofs also produce good results, typically around 80–85% of a south-facing system. Your installer will assess orientation, shading, and structural suitability before quoting.
How much electricity will solar panels generate?
A typical 4kWp system in Ireland generates around 3,400–3,800 kWh per year, roughly enough to cover 40–50% of an average household's electricity consumption. Actual output depends on roof orientation, shading, and local weather patterns.
How long do solar panels last?
Modern solar panels typically come with a 25-year performance warranty and can continue generating electricity for 30 years or more. Inverters generally last 10–15 years before needing replacement. Panels require very little maintenance over their lifetime.
Can I sell excess electricity back to the grid?
Yes. Under the Clean Export Guarantee (CEG), energy suppliers in Ireland must offer a payment for surplus electricity exported to the grid. Rates vary by supplier, so it's worth shopping around. Your installer can advise on how to maximise self-consumption and export income.
Battery Storage
Do I need a battery with solar panels?
A battery isn't essential but it increases the amount of solar energy you use directly. Without a battery, excess electricity generated during the day is exported to the grid. A battery stores it for use in the evening when your panels aren't producing, reducing how much you buy from the grid.
How much does a solar battery cost?
Home battery systems in Ireland typically cost between €3,000 and €6,000 depending on capacity (usually 5-10 kWh). There is no standalone SEAI grant for battery storage, but batteries installed with solar panels qualify for 0% VAT (vs 23%), saving €1,000-€1,500. Batteries make the most financial sense for households with high evening electricity usage.
Can I add a battery later?
Yes. Most modern solar inverters are battery-ready, meaning a battery can be added after the initial installation. If you're not sure about battery storage now, ask your installer to fit a battery-compatible inverter so you can add one later without extra cost.
Grants & Incentives
What SEAI grants are available for solar panels?
The SEAI offers a solar PV grant of up to €1,800 for homeowners. The grant is €700 per kWp for the first 2kWp and €200 per additional kWp up to 4kWp. The grant is paid after installation by an SEAI-registered installer. You don't need to apply before getting a quote.
Do I qualify for the SEAI solar grant?
To qualify, your home must have been built and occupied before 2021, you need to use an SEAI-registered installer, and your home must have a BER (Building Energy Rating) assessment. The grant is available to homeowners only, not renters or new builds.
Can I claim the grant and sell electricity back?
Yes. The SEAI grant and the Clean Export Guarantee are separate schemes. You can receive the installation grant, use your solar electricity, and sell any surplus back to the grid. The two incentives work together to improve the financial return on your investment.
