Power Your Home With Free Electricity & Avail Of The SEAI Grant


About Photovoltaic

Did you know the photovoltaic technology used in solar panels is used in space to generate free electricity? Photovoltaic cells work (it’s called the Photovoltaic effect and was discovered way back in 1887 by Heinrich Hertz) by converting daylight into electricity but this technology should not be confused with existing solar water heating systems, that are less efficient and requires direct sunshine, water pipes and storage tanks.  Lennon Solar can provide a system which saves money on your utility bills and will generate an index linked tax free income guaranteed for 20 years.

The Benefits Associated With Solar PV Installation Include:

Generates Electricity

Battery Storage

Cheaper Bills

Reduces Carbon

Electricity Reductions

Generate your own electricity with your very own Solar PV system, locking in your own electricity prices for 25+ years. On average, a solar PV system can save you up to €1100 per year on your domestic electricity bill. This will make a big difference to your household running costs, allowing you to save for what really matters.

Battery Storage

Store excess electricity with a battery add-on, allowing you to later consume the stored energy when your demand exceeds the production of your panels.

Cheaper Energy Bills

Generating your own electricity with our Solar PV system, you can expect to save up to 70% on your electricity bills.

Reduce Your Carbon Emissions

By installing a PV system you are doing you part to lower your carbon footprint and help protect the planet.

How Our Solar PV Systems Work

Your home’s roof could be saving you money right now. By installing our Solar Photovoltaic (PV) system on your home you can generate clean green renewable energy from daylight – a free and natural resource.

Solar Panels

We install our 420w panels on your rooftop to optimally absorb the sunlight and convert to DC (direct current – like a battery) electricity.


The DC electricity is then converted in an inverter to AC (alternating current – like the electricity in your domestic socket).

Heating your water

As well as producing electricity for use all around the home, when there is an excess of supply, it will heat your water before being exported to the grid.

Battery Storage

Save excess electricity and use it when you need it with battery storage!

Guaranteed Electricity

Our Solar PV systems carry a 25 year performance warranty, meaning you’ll be getting free electricity for at least that period and actually longer.

Long-term warranty

We offer monitoring and protection on your solar panels so you
can benefit from peace of mind.

Examples of Grant Amounts

From January 2024, the maximum SEAI grant available for solar PV panels will be €2,100. The grants will change to €800 per kWp for up 2kWp. €250 for every additional kWp up to 4kWp. Examples: €1600 for 2kWp solar panels, €1850 for 3kWp solar panels, €2100 for 4kWp solar panels. SEAI Grants
