Solar Panel FAQs

The questions Irish homeowners ask us most, answered plainly.

How do solar panels work?

Solar panels use photovoltaic (PV) cells to convert daylight (not just direct sunlight) into electricity. This powers your home, reducing dependency on the grid. Excess energy can be stored in a battery, heat your hot water, or charge an EV.

How much can I save with solar panels?

Savings depend on your system size and usage, but Irish homeowners typically see at least a 50% reduction in electricity bills. Many solar panel systems achieve a Return on Investment (ROI) in 4-6 years, offering free electricity for decades after.

What size solar panel system do I need?

This depends on your consumption and roof space. We analyse your bills to design a solar panel system that fits your actual needs, ensuring you don't overpay for a system that's too big. We also future-proof designs for later expansion.

Is my roof suitable for solar panels?

Most Irish roofs are suitable for solar panels as long as they are in good condition. We can install on almost any roof structure. Our on-site survey will confirm suitability before any work begins.

What grants are available for solar panels in Ireland?

Yes! The SEAI grant offers up to €1,800 for residential solar panel systems (for 4kWp and above). There is also a grant of up to €300 for EV chargers. We handle the paperwork for you.

Do I need planning permission for solar panels?

Generally, no. As of October 2021, Irish planning laws changed so you don't need permission for rooftop solar panels unless you live in specific zones like air traffic control areas or protected structures.

Is battery storage important for solar panels?

Yes, it helps you use more of the power your solar panels generate (self-consumption) rather than sending it to the grid. It also allows 'Time of Use' charging—filling the battery with cheap night-rate electricity to use during expensive peak hours.

What maintenance do solar panels need?

Solar panels are generally self-cleaning with rainwater—Ireland's climate is ideal for this! Our systems come with a 2-year installation warranty, 12-25 year panel manufacturer warranty, and 10-year battery/inverter warranties.

How long does solar panel installation take?

Typical solar panel installations for Irish homes take just 1-2 days. External roof work and internal electrical work are usually done simultaneously to minimise disruption.
