ADVANTAGES of Using Solar Energy

Truly Renewable Energy

Unlike fossil fuels, solar energy is abundant all over the world. Generate free energy from the sun all year round, even on overcast days, thanks to solar PV technology.

Cut Down on Energy Bills

Homeowners in Cork stand to save a substantial amount on energy bills with solar panel installations. A typical residential 4 kW system, for example, can save around €900 per year.

Low Maintenance Costs 

Since there are no moving mechanical parts in a solar PV system, the maintenance costs are low. Routine cleaning of the panels themselves keeps them operating at peak efficiency.

An Excellent Investment

The full cost of a residential system is well worth every euro. Depending on the configuration and size of the installation, a typical break-even point ranges from around 5-7 years.

Get Paid for Surplus Energy

Starting in mid-2021, homeowners in Ireland can get paid through Feed-in Tariffs, according to the European Union, for surplus energy generated from renewable sources such as solar PV systems.


Since May 1, 2023, the Irish government has reduced the VAT rate on solar installations from 13.5% to 0%. This will save you hundreds of euros on solar panel installation costs.

Installing PV Solar Panels in Cork 

Contrary to popular belief, modern solar PV installations work well during cloudy, overcast days. Cork is well-situated within Ireland to generate solar energy, especially for south-facing or east-west orientations. Moreover, research indicates that solar panels tend to work better in cooler climates, which makes Ireland ideal for residential solar PV installations. The fact that Cork is located in the sunnier southeast further helps to generate additional energy.

There has never been a better time to invest in high-quality solar panels in Cork. Wizer Energy has a wide range of solutions for homeowners and businesses to start generating their own clean, renewable solar energy today.

A clients home showing a recent solar panel installation in Cork

We recently had the privilege of completing a full solar energy installation for Mr. Finghin O’ Driscoll semi-detached home in Cobh, County Cork. As part of this project, we performed the following:

  • 3 kWp solar PV system size: We installed 10 Znshine 300-watt solar PV panels, generating 2,700 kWh per year. We used a 3-kW Trannergy inverter.
  • Warranties: The solar panels come with a 12-year warranty and a 25-year performance warranty. The inverter comes with a 5-year warranty and a 5-year warranty for additional inverter parts.

  • Performance: Finghin now receives 49% of his household energy from solar on average every year.
  • Environmental benefits: Finghin’s home now avoids 940 kg of CO2 per year, the equivalent of 20 long-haul flights or 181 trees planted.
  • Energy savings: Finghin is now saving nearly €100 every two months on his energy bill and stands to save over €12,000 in lifetime energy bill savings.

Frequently Asked Questions

Solar panels work by absorbing sunlight along the surface of the panels. This generates an electrical flow called direct current (DC). The solar panels must convert this current into alternating current (AC) to be useful in household applications, so an inverter is used to convert the DC into AC. 

It is dependent on the configuration and energy consumption, but to give an example, a typical household in Cork with a south-facing solar PV installation will cost around €7,000 to €13,000. Other factors to consider include financing, such as the SEAI Grant, which will affect the final cost. 

Solar panels are certainly worth the investment in Cork, given its sunnier south-eastern location in Ireland. Nevertheless, overcast and cloudy days will still generate sufficient solar energy to make the investment worthwhile. Not only will homeowners save hundreds on energy bills each year, but the solar panels will pay themselves off completely in anywhere from 5 to 10 years. 

Yes. In Ireland, homeowners who wish to retrofit their roofs with solar panels are eligible for funding from SEAI Grants. There are specific requirements to be considered eligible, and the amount of funding can vary depending on the kilowatt-peak (kWp) of the system and the desired energy storage system. Homeowners can apply online using the SEAI claims portal here.

It depends. Do you want to enjoy savings on your energy bills, lessen your dependence on energy companies, and make a sound investment in your property value and home equity? If you’re considering solar panels for your home in Cork, get in touch with us at Wizer Energy, and we can guide you through the process.

Depending on your energy consumption and the orientation of your panels, the number of solar panels needed may vary. Generally, a south-facing or east-west-facing configuration for a 3.3 kW solar PV system with typical daily consumption requires around 10 solar panels. This 10-panel system would easily power your home’s base load plus a white good, i.e., a dishwasher or washing machine, even in dull weather. If you’d like a more accurate quote for your home in Cork, reach out to us at Wizer Energy. 

Each square metre of solar panel generates around 195 W on a sunny, clear day. To use a more realistic example, a typical 3.3 kW residential solar PV installation that is about 20 square metres in area will generate around 3,200 kW per year, which is about 45% of the average annual electricity consumed in an average Irish home.  

Depending on your energy consumption and the orientation of your solar panels, the roof space required to install solar panels varies. For a typical 3.3 kW solar PV system in Cork, around 20 square metres are needed to install about 10 solar panels. 

We’re thrilled to announce our collaboration with Finance Ireland, providing new financing options for solar panels, including convenient loans tailored for your home. Please visit our Solar Panel Finance page for more information on solar loan options.
