PV Solar
How do Solar PV panels work?
Light from the sun, or more specifically, photons from the sun (aka solar energy) hit the photovoltaic (PV) array which causes an electric current to be generated.

Maintenance:
Solar PV systems in Ireland are low-maintenance, requiring occasional cleaning to ensure optimal performance. Panels tilted at 15° or more benefit from natural rain cleaning. Ground-mounted panels may accumulate debris, which can be easily removed with warm water and a brush or a high-pressure hose.
Purchase Solar Panels in Ireland:
At Laltec Solar, our highly skilled engineers possess extensive experience in planning and installing solar PV panels for optimal performance and safety. Our team will keep you informed throughout the installation process, and our customer support ensures your panels work seamlessly for years to come.
We use the latest equipment, technology, and training, backed by the necessary certifications, to deliver the highest quality solar PV panels and installations on the Irish market.
Solar PV Panel Installation:
Our process begins with a free, no-obligation property assessment, which includes measuring your roof’s suitability for solar panels. During this assessment, we review your utility bills and calculate potential savings and available tariffs. With your permission, we evaluate if the panels can pay for themselves and benefit you through our online portal.
If you’re satisfied with the figures and wish to proceed, we’ll seek financial backing for the system. The repayments may be covered by tariffs and the savings generated from the solar system. If self-funding isn’t feasible, you have the option to make a small contribution.
If all aligns, we proceed with the installation of your system, and you become the owner, reaping all its benefits. With a lifespan of at least 20 years, it can yield an average of €16,000.
Commercial and Domestic Solar Panels in Ireland:
Solar panels offer substantial savings for both domestic households and commercial properties in Ireland, reducing carbon footprints and energy bills significantly. Commercial properties, in particular, benefit from reduced electricity bills, potential tax relief, and additional income opportunities.
Solar Power and Battery Storage:
When paired with a battery (commonly known as a home energy-storage system), Solar PV panels can store excess energy for later use, especially during peak hours or when your solar system can’t meet your household’s energy needs. Brands like Puredrive, Dryness, Sungrow and Huawei offer various energy-storage solutions that can be retrofitted to your existing solar PV system.
Determining the Number of Solar Panels:
There’s no fixed requirement for the number of solar panels, but generally, more panels generate more electricity and increase your potential savings. Coupled with solar battery storage, you can further reduce your electric bills by storing excess energy for future use.
A common solar PV system size in Ireland is a 4kW system with approximately 10 panels or a 5kW system with 16 panels plus, depending on the size of your roof. The expected annual savings will range €1200 to €3000, depending on what rate the consumer is paying for electricity.

Solar PV Panel FAQs
How does Solar PV work in Ireland?
Solar PV panels in Ireland capture energy from sunlight and convert it directly into electricity for use in your home. They also capture energy from natural daylight.
Do Solar PV panels work on cloudy days in Ireland?
Yes, Solar panels can function in low light conditions, but they perform optimally in direct sunlight.
Is planning permission required for Solar PV installations in Ireland?
In most cases, planning permission is not needed for domestic Solar PV installations. Since April 2008, solar panels have been classified as ‘permitted development.’ Exceptions may apply if your house is a listed building or located in a conservation area. Building regulations still apply to ensure installation safety.
How much roof space is necessary for Solar PV in Ireland?
Solar systems can be as compact as 8m² in Ireland.
What is the lifespan of a Solar PV system in Ireland?
The panels last between 20 & 30 years in Ireland depending on the quality of the install and the manufacturer.
How long does a Solar PV installation take in Ireland?
On average, installation takes about 2 days, but the duration can vary based on the size and complexity of the solar panel setup. For specific installation timelines for your home, please enquire online.
Can Solar PV panels generate income in addition to savings on electricity bills in Ireland?
Yes, you can typically earn money from your Solar PV panels by exporting surplus electricity back to the grid in Ireland. Often through exporting tariff initiatives to which energy companies in Ireland subscribe. For pricing information and an energy assessment for Solar PV installation, contact Laltec Solar.
What are the regulations for fitting Solar PV panels to your roof in Ireland?
When installing Solar PV panels in Ireland, there are several regulations to adhere to, including:
- Minimizing changes to the appearance of your roof during installation.
- Removal of panels when they are no longer used for electricity generation.
- Ensuring that panels do not extend more than 500mm beyond the roof boundary or exceed the highest point on the roof.
