Photovoltaic panels are solar panels that convert sunlight into electricity using photovoltaic cells. These cells are made of a special material (usually silicon) that generates an electric current when exposed to light. Unlike solar thermal systems — which heat water — PV panels produce electricity that can be used to power lights, appliances, electric showers, heat pumps, and even charge electric vehicles. ## How do PV panels work? Here’s a simple breakdown of how PV systems generate electricity: - Daylight hits the panels, causing electrons in the PV cells to move - This creates direct current (DC) electricity - An inverter converts the DC into alternating current (AC), which your home can use - Any surplus energy can be stored (if you have a battery) or exported back to the grid Even on cloudy days, PV panels generate electricity from ambient daylight — which means they’re well-suited to the Irish climate. ## Are PV panels suitable for Irish weather? Yes — PV panels work very effectively in Ireland. While we may not get Mediterranean sunshine, we do have long daylight hours, especially in spring and summer. Ireland’s relatively mild temperatures also help PV panels operate more efficiently than in very hot climates. A typical system can generate enough electricity to meet up to 70-80% of a household’s annual electricity needs. ## What types of PV panels are available? There are three main types of photovoltaic panels used in Ireland: | Type | Efficiency | Appearance | Cost | | --- | --- | --- | --- | | Monocrystalline | High (18–22%) | Sleek black panels | Higher | | Polycrystalline | Medium (15–17%) | Blue-tinted panels | Moderate | | Thin-film | Lower (10–13%) | Flexible or dark flat panels | Lower | Most homeowners choose monocrystalline for the best balance of efficiency and long-term value, especially if roof space is limited. ## What to consider before installing PV panels Before installing solar PV panels, think about: - **Roof orientation and angle** – South-facing roofs work best, but east and west are also effective - **Shade** – Avoid large trees or chimneys that may block sunlight - **Available space** – A typical 3.2 kWp system uses 8 panels and requires around 15–20m² - **Energy usage** – The size of your system should match your electricity consumption - **Future upgrades** – You might consider battery storage or EV charging in future A registered installer can assess your home and recommend the right system size and panel type for your needs. ## Cost and grant support for PV panels in Ireland In Ireland, a standard solar PV system costs between €6,000 and €10,000 — depending on size, panel type, and any extras like battery storage. The SEAI Solar PV Grant can reduce these costs by up to €1,800, making solar more affordable for homeowners. You can also earn money through the Clean Export Guarantee (CEG) for any excess electricity sent back to the grid. ## Find the right PV system for your home Photovoltaic panels are a clean, proven technology that can make your home more energy efficient and help you take control of your electricity costs.
