What Are Solar Panels and How Do They Work?

Solar panels, also known as solar PV (photovoltaic) panels, convert sunlight into electricity. These panels contain silicon cells that create an electric field when exposed to sunlight, causing electricity to flow.

This electricity is converted from direct current (DC) to alternating current (AC) through an inverter, making it usable for all household appliances like fridges, freezers, and televisions.

Do Solar Panels Work in Ireland?

Yes! Solar panels are highly effective in Ireland, benefiting from a good average number of solar hours per day throughout the year. While the panels generate more electricity during longer summer days, they also produce free electricity even on cloudy or dark winter days.

Almost all types of domestic dwellings in Ireland are suitable for solar panels, except those with no installation space, such as certain apartments. For homes lacking roof space but with available ground area, ground-mounted solar systems offer an effective alternative.

 Trustindex verifies that the original source of the review is Google. Finally made the decision to go ‘Solar Panels’ for my house in Cork. I contacted a number of Suppliers and met their representatives but I just wasn’t convinced. Fortunately for me one guy stood out - he was particularly friendly, relaxed, struck up an instant relationship with my German Shepherd, Rebel, over a cup of tea (!), could explain all the 'Solar jargon' in an uncomplicated way, appeared to have endless patience and didn't come across even remotely pushy. The 'deal maker' that locked me in was all of the above plus I felt that he really wanted me to have a successful www.AEI.ie Solar service and investment experience. Daniel Costello is an absolute credit to AEI Solar! I've recommended him and AEI to many neighbours and friends since my installation. I've been back and forth to Daniel over the past few months looking for clarity in the various packs/proposals, checking various installation dates etc. and he has been superb. 5 Stars for Daniel and www.aei.ie from this particularly happy customer.

 Trustindex verifies that the original source of the review is Google. It's been 12 months since AEI installed our solar and battery but I only recently bought an EV and at the same time I had development  a small invertor problem and logged a ticket for support. After a number of emails back and forth Trevor called me and explained in simple terms on how a system should be run based on my usage pattern, much more so than any email could explain. His advise was simple to understand, we agreed a plan and he implemented it. Top class.
