What do I need to know when considering PV?


  • Number of Panels: The number of panels you put on your roof should be dictated by a) how much room you have on your roof, and b) sizing a system that will meet your demands. Generally speaking we recommend a minimum of 6 panels. In LVP, we have a number of options when it comes to panels, the output of these panels ranges from 340W to 395W. The datasheets for some of our panels available can be found at the following link; https://www.lvprenewables.ie/brochures/
  • Water diverter option: Excess energy can be used to heat a solar water immersion. This is used purely as a surplus device, and would ordinarily be fitted in some of our smaller applications when batteries are not deemed a financially viable option. (It should be noted that most of our thermodynamic solar hot water range systems contain an inbuilt hot water diverter)
  • Batteries: In LVP, we supply batteries in a number of different sizes. Our batteries range in size from 2.4KW to 8.2KW. Most of our batteries can have additional batteries of the same size added, should you wish to increase your storage options in the future. We generally only recommend batteries if you are installing in excess of 8 panels on the roof.
  • Optimisers: Occasionally, we come across applications where a number of panels are in shade for part of the day. In this situation, we can fit optimisers in order to limit the impact that this shade will have.


There are certain restrictions in place when you look to install solar panels in your home. It should be noted that the homeowner is responsible to ensure that their installation complies with all planning regulation. Some of the main points are listed below; 

  • A maximum of 12 square metres of panels are permitted on your roof without planning permission. This is 6 or 7 panels generally
  • Panels placed on the ground outside do not require planning permission and can be used to help power your house.
  • Up to 6kw of panels can be installed on a single phase ground mounted system meaning in some cases you could almost offset your annual electricity bill.
  • The solar panel shall be a minimum of 50cm from any edge of the wall or roof on which it is mounted. 



The amount that you save installing solar panels will generally vary, dependent upon the size of the array installed, and the utilisation of all energy used. 1KW of Solar PV will generally provide between 800 and 1000KW of free electricity. Please click on the link below to give you an indicative idea of what you may be able to save 



  • Support is available to all owners of dwellings built and occupied before 2021 and where SEAI have not previously provided support for solar PV system at that address.
  • €900 for every kWh up to max 2kWp.
  • €300 for kWh 3 and KWh 4
  • Maximum Grant of €2400
  • Only an installer who is on SEAI’s Renewable Installers Register for solar PV can certify the installation
  • Once the system is installed, you will need to get a BER assessment
