What's Solar Energy?
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy etc. For the most competitive PV solar panels Ireland cost, approach us.
The Solar Panels that we use in our homes fall into two general categories:-
- Solar Thermal
- Solar Photovoltaic (PV)
Solar Thermal Panels
Solar panels that produce hot water are known as solar thermal collectors or solar hot water collectors. There are a range of technologies which transfer the energy from the sun into space heat or hot water; and are available in the market at a reasonable PV solar panels Ireland cost.
Solar Thermal panels or solar PV Ireland can be either Flat-Plate or more commonly Evacuated Tube collectors. China is the leader in their deployment of solar hot water systems (210 GW by 2020) and Israel and Cyprus are the per capita leaders in the use of solar water heating systems with over 90% of homes using them. In Ireland 60-70% of the annual domestic hot water demand can be provided by solar heating systems with temperatures up to 60°C. Installations of Solar Electric Ireland will perform very satisfactorily provided care is taken to design solar system correctly and you also ensure that the installation is completed to a high standard.

How do Solar Thermal Panels work?
Solar panels heat up water directly. A pump circulates a fluid (antifreeze) from a storage tank through a manifold in the solar tube collector. The fluid of Solar Electric Ireland is then heated by heat from the sun absorbed through the tubes of sealed glass (vacuum pipes) and returns to the tank thus heating the water. Pipes are located on the south facing roof where they can receive the most sunlight. The special type of hot water tank is always fitted with solar panels and can have two or three coils to tie in with the conventional heating system.

Solar Thermal FAQ
What is solar collector?
Solar collector is the device that converts solar energy into heat.
Do solar water heating system work in winter?
Solar water heaters will heat water to a certain degree almost every day of the year. Even in December a solar thermal installation can heat the water up to 20°C. Various factors can influence the amount of water a solar heating system and can heat.How much hot water can a solar water heating system provide?
A solar water heating system can provide between 95-100% of all your hot water needs during the summer. In the spring and autumn, 60-70% of the hot water usage can be provided and in winter this figure is 10-20%. The ideal installation will provide approximately 65-70% of the hot water needs on average annually.
How hot can solar heated water get?
Solar water heating system can heat water above 80°C on a sunny day.
Does Ireland get enough solar energy to make solar water heating viable?
Surprisingly, when it comes to solar PV, Ireland has the solar energy equivalent to that of Germany, UK and even parts of France. This energy is provided by both direct sunlight (40%) and indirect sunlight (60%). This means that even when the sky is overcast, the sun’s radiation (sunlight) is available at ground level and can be converted into useful heat by solar thermal heating system. Plus, you do not have to worry about PV panels Ireland cost, as you can buy it easily at a pocket friendly rate.
Do I need to use a backup heat source when I am using solar heating?
You do need to use backup heat source with solar. Generally the system comes with twin or triple coil cylinder to produce hot water. One coil is for solar and one or two for another heat source/s. In this way, if the solar panels cannot produce enough heat, the primary heat source will make up the shortfall.
Can I use solar to support my central heating?
Yes, you can increase the amount of solar panels being used, in order to provide backup for heating and hot water for your house. A large storage cylinder is usually used, and the main heat source in conjunction with the solar, will heat this cylinder. Look no further for electric panel heaters Ireland. Approach us today!
How much will I save if I install a solar water heating system?
The money saved from the installation of a solar water heating system in terms of a lower utility bills depends entirely on how much hot water is required. The majority of homeowners will have saved enough from their electricity bill within roughly five years to cover the costs of the solar water heating system.
Do I need planning permission?
Solar roof systems fall under permitted rights so you do not need planning permission although if you live in a listed building you should contact your local council.
Solar Photovoltaic (PV)
Solar panels that produce electricity are known as solar photovoltaic (PV) modules, which are made from a thin layer of silicon behind toughened glass. These panels generate DC electricity when exposed to light. They are manufactured from an array of photovoltaic cells which generate DC electrical current when exposed to light. This DC electrical current is converted via an inverter to AC which is then used to power all the electrical items in the house.
If you don’t have a requirement for all of the electricity generated from your Solar PV Panels, it currently goes back to the grid with no benefit to the homeowner. To make use of this free energy the Solar PV Panels can be used in conjunction with battery storage or water heating storage.
We offer a device called Immersun that will divert any excess electricity into the domestic hot water storage cylinder. This reduces the cost of heating your hot water by conventional means.
The benefits of Solar Photovoltaic (PV) panels:
Reduce your electricity bill. A typical domestic Solar Photovoltaic (PV) system can save you approximately €800 annually on your domestic electricity bill.
Guaranteed output. The output of your PV solar panels is guaranteed for 20 years from the time of installation.
Free Electricity which safeguards against increasing energy costs.
Improved Building Energy Rating (BER). Installing a solar panel will raise your BER. This has the added benefit of increasing the value of your property which is great when it comes to renting or selling your home.
Silent and maintenance free.
Reduce your carbon footprint.
Solar Photovoltaic (PV) FAQ What is a Solar Photovoltaic Panel?
What is a Solar Photovoltaic Panel?
A Solar Photovoltaic Panel is the device that converts solar energy into electricity for use in the home.
Does Solar PV need direct sunlight?
Solar PV produces its energy from light rather than solar radiation so they will still generate energy even on overcast and cloudy days.
Do I need planning permission?
A home is allowed up to 12 square metres of Solar Panels (and represent less than 50% of the total roof area) without having the need for planning permission. Typically, a Solar Panel array would be less than that so planning permission would not be required. Get in touch with us and get electric panel heaters Ireland for your home.
