SOLAR PANEL FAQ

There is an opinion out there that Solar Panels (Solar PV) would not work in Ireland, this stems from people thinking that we don’t get enough sunlight in the summer, never mind the winter for solar panels to produce energy.

This however is not true, solar PV works in daylight as opposed to the heat from the sun. Ireland has the same annual Irradiation levels as many parts of central Europe, ranging from 1200 kWhr/m2/yr in the south of the country to 1000 kWhr/m2/yr in the north of the country, a good average for the entire country is 1100 kWhr/m2/yr.

If you consider our typical winters would not be as bad as many parts of central Europe, our mild climate is ideal for solar PV as we never get too hot or too cold and we have good light levels for a large part of the year.

Solar Panels (Solar PV) are a clean source of energy  – Solar PV uses the sun’s energy to generate clean green electricity that can be used directly in place of conventionally generated power in your home or business. It is one of the easiest and most beneficial renewable energy technologies to add to any building, whether commercial or domestic.

Solar PV saves you money  – You not only save money on your electricity bills, but you are protecting yourself against inevitable price rise from energy suppliers and potential energy shortages in the future.

Solar panels reduce your carbon footprint – Each unit of electricity generated by a solar PV system reduces the amount of CO2 emitted from conventional power stations. Over 25 years, a 2KW solar panel array will generate over 36,000 units of electricity and save over 20 tonnes of CO2.

Solar panels are versatile  – Solar PV can be installed at almost any location; usually mounted on a building’s roof, but they can also be integrated into the fabric of the building, replacing traditional roofing, glazing or cladding materials, or on simple ground-mounted structures.

Solar PV systems will take power from the solar panels “first” naturally and will only draw power from the grid if there is insufficient power available from the solar panels. The flow of electricity in a system is determined by the electrical potential at all points in the system. The simplest analogy is to think of the flow of electricity in a network of conductors connected to the grid as being like the flow of water through a network of pipes connected to a water main. If there is more pressure in the network of pipes than in the water main, water will flow out into the water main – and vice-versa.

Solar PV modules have a manufacturer’s performance warranty of 30 years and a working lifetime of 35 years and beyond. As the photovoltaic effect is a naturally occurring phenomenon, there is nothing to say that the panels will not continue to create electricity for as long as they are in sunlight. A solar panel system that is designed, installed, and maintained well will operate very efficiently for at least 30 years. The best way to ensure and extend the life and effectiveness of your PV system is to purchase quality components from a reputable company that will guarantee that your system is correctly installed and commissioned.

Here at NRG Panel we use tier 1 solar panels with some of the highest manufacturer warranties and efficiency levels on the market.

Solar panel prices Ireland can vary greatly. It is really important that when you are comparing quotations for solar panels you compare like with like on all components of the system, there are cheaper models on the market however, these are not of the same quality or efficiency. You also need to consider the company you are dealing with, is this an established company with quality customer service that will be there in 5-10 years should you have any issues with your solar panels down the line.

It is very hard to give a direct quote as it all depends on the type of system the consultant designs for you, but prices start from around €7,500 for a 2.5kWp system before any grant subsidies.

The solar PV system designed for you is dependent on a number of factors including your electricity usage, lifestyle and the details of your home and roof, this is why it is important to have a consultation to ensure we are offering you a bespoke system specifically designed for your needs to maximise your return on investment.

No, you will still have an electricity bill with Solar PV. We aim to design a bespoke system for you that will reduce your bills by around 50% –  The typical payback period on a solar panel system of approximately 6-7 years.
