How it works: Solar panels FAQs
Find out everything you need to know about solar panels
Yes, of course. At Flogas we take safety very seriously. That’s why we only partner with fully trained, accredited, and insured solar panel experts, with thousands of installations completed to date.
Those partners only use fully CE-certified panels, invertors, divertors, and switchgear, and are fully registered with Safe Electric for your absolute peace of mind.
In addition, our solar panels are guaranteed for 25 years, with self-cleaning technology to minimise maintenance. Our smart Batteries also come with a 10-year guarantee, so once you have a system installed there is very little to do but enjoy cheaper electricity bills from the moment the installation is complete.

Fluctuating energy prices means that the savings you can make with solar repays your initial investment faster than ever. At Flogas, we supply the latest and most efficient solar panel technology at a great price.
By maximising solar power production at your home you can cut electricity bills by up to 50%, which means payback of the costs of installation for many households is under 10 years.
With our solar systems guaranteed for 25 years, it’s easy to see how solar panels can help you save money in the long term.

The cost of purchasing and installing solar panels has come down considerably over the last 10 years. The actual price of a solar PV system depends on the size of the system and the accessibility of the roof or site.
The Sustainable Energy Authority of Ireland (SEAI) grants are available to help with the cost of purchase and installation. Typical installations of solar PV panels in a standard house will cost from €4,500 net of grant, depending on your requirements and your property.
Yes, you can.

You can install solar panels on any house of any age, but SEAI grants are only available to homes with a BER (energy rating) of B3 or higher. This is because the SEAI wants to encourage homes with poor energy ratings to improve other elements first before investing in solar panels
Not usually. Solar PV systems installed at a domestic house under 12 sq. metres (and representing less than 50% of the total roof area) are exempt from planning.
That means that you should be able to install a significant solar panel array on most medium-to-large properties in Ireland without planning permission.
The figure will vary depending on your make and model, but the average electric vehicle can travel 15,000km a year on around half of the energy used to power the average house.
How many solar panels this requires will come down to your car, home, and location. It would be fair to say that most average solar systems can make a significant contribution to cover most, if not all the electricity used by an electric vehicle.
By combining solar panels with a smart battery you can also power your electric car with cheap electricity day or night.

Solar panels have become more and more efficient and affordable in recent years. This combination, along with rising electricity prices, means that solar is now a very smart way of producing free, cheap, and renewable energy to power your home, car, farm, or business.
Solar PV panels are based on tried-and-tested technology that has been around for decades. We’re so confident of their durability, the solar panels we supply come with a 25-year guarantee. That means you get the peace of mind of knowing that you can enjoy increased efficiency, significant savings, and trouble-free usage for many years to come.
Solar panels in Ireland are best placed on a south-facing roof to maximise the amount of sunlight available. Changes in planning laws mean that you can position panels on the front as well as the back of your house, as long as no more than 50% of the roof is covered with panels.
Our free technical site assessment will give you the best options for saving with solar at your home. The best rooftops for solar panels are those that are south-facing and away from trees or adjacent structures that could cover them with shade.
The roof should also be in good condition, as solar panels need to be affixed to a safe and secure base. In some cases, where space permits, it may also be possible to mount the panels at ground level also.
Absolutely! Sure, we get more rainy days than other countries, but modern solar panels don’t need year-round sunshine to work.
While it’s true that solar panels in Ireland are unlikely to produce the same amounts of energy as solar panels in a sunnier country such as Spain, solar panels can still produce significant energy, particularly from May to September.
Studies show that even on a partly cloudy day solar panels, new super-efficient solar panels can work at 80% of their full capacity, and because of Ireland’s geographical position, a south-facing roof can maximise the benefit of those long days in the summer months.
While heating is not a priority in the warmer seasons, hot water, household electricity, and the increasing use of electric vehicles mean solar can provide significant year-round savings to your energy bills.
When combined with smart batteries to power your house with off-peak energy, the savings can be extraordinary.
Our home energy experts can help you decide on the number of panels that are suitable for your home, based on an estimate of the energy they will produce.
The amount of electricity generated from month to month by an electric panel array will depend on a range of factors. These include the size of the system that’s been installed, the location of the house, and the direction in which the panels are facing to capture sunlight.
Most properties will need the maximum number of solar panels available to them based on roof area and planning permission.
Of course, you can install a smaller number of panels and still reduce your electricity bills. While solar PV panels are very efficient, they are unlikely to provide all of your electricity requirements, particularly in the winter months.
Plus, you can now sell surplus electricity back to the national grid, which could reduce your costs and even provide a passive income to your home.
Renewable energy is becoming increasingly important for all of us, particularly as we face geopolitical uncertainty. That means it’s unlikely you can ever have too many solar panels. Our solar installation experts can help you decide the right number for you.
Put simply? They turn energy from the sun into power for your house. Now here comes the more technical bit: Photovoltaic solar panels are an innovative technology that harnesses solar energy to generate electricity to power everything from charging phones to operating your electric shower.
So how do solar panels work? Solar PV Panels are made up of thousands of small photovoltaic cells. Each cell is a sandwich of two layers of silicon, which have different positive and negative electrical charges. When a photon of light hits the first layer, it knocks an electron from it into the sandwich and creates an electrical current. This current is directed by metal plates into wires and into an inverter, that turns the AC current into a DC current we can use in our homes.
This smart technology has been engineered and perfected over decades to create the smart, efficient solar panels that we use today.
