A Quick Guide to Solar PV System in Ireland

Published on
February 7, 2023

Ireland is a great place to install solar PV systems. The country offers very high solar radiation, which means that solar PV systems can generate a lot of electricity. There are also many grants and incentives available to help offset the cost of solar PV systems in Ireland .With the increasing expenses these days, your home's roof could save you money right now. With the Solar Photovoltaic (PV) panels, your home can produce clean, renewable, and sustainable energy from daylight which is a free and renewable source of energy.

What are Solar PV systems?

A Solar Photovoltaic (PV) system comprises a solar panel or panels with an inverter and other mechanical and electrical hardware that utilize energy from the Sun to produce electricity. PV systems can range in terms of size, from a small rooftop or portable systems to huge utility-scale power plants. Solar PV Systems is a process developed in the 1800s that has seen an enormous change in its use for both residential and commercial use. Solar PV turns sunlight into electricity using the aid of solar panels.

How do Solar PV systems work?

Solar PV systems in Ireland generate energy by harnessing sunlight's energy so that they can generate pure energy. The Solar photovoltaic (PV) systems turn sunlight into electricity. Solar PV panels are made up of cells that contain solar photovoltaic materials. When sunlight hits the solar cells, the photons knock electrons loose from their atoms. This creates an electric field across the cell that allows electrons to flow through the material to metal contacts on the sides of the cell. The electrical current generated can then be used to power your home or business. In addition, every extra watt generated by your solar panel is transferred to your utility grid to supply clean energy to your city. Your system automatically transfers your surplus electricity to the grid of the public power system. This means that you could be eligible to be credited for the extra energy your solar power system produces. This could mean that you'll have a lower energy bill from your current provider of energy.

What is the difference between photovoltaics and solar panels?

Many people get confused between solar thermal and photovoltaic collectors since both are on roofs of buildings and the ground using structures specially designed for this particular function and making use of the sun's energy.However, the solar energy produced by thermal radiation is absorbed by two systems to serve entirely different reasons. Photovoltaic panels are designed to convert the energy of thermal into electricity, while solar panels convert sunlight into heat. This is why the two solutions don't compete with each other instead they work in conjunction.

How efficient are PV Solar Panels and what are the factors affecting them?

Traditional solar panels can aid in meeting some of the power requirements of the building.

  • 1 sq. 1 m of solar panels made of silicon could produce 150W of power on a sunny, clear day. This is enough power to charge laptop computers.
  • A solar system for your home that is 20 square meters (~3kW) and well-placed could generate approximately 2,600kWh of power per year. This is nearly 40% of the annual average energy consumption of an Irish house.
  • Solar PV systems can operate on cloudy days in Ireland but not at their capacity.

The amount of energy generated by a solar panel is affected by the following factors:

  • Temperature- High temperatures can be detrimental to performance. We employ a standard sunlight intensity to determine the power nominally produced by PV modules in indoor environments at 25°C.
  • Soiling- Materials built upon the PV panels could stop light from reaching solar cells, which reduces the power generated. The loss of power due to soiling is extremely dependent on the kind of soiling (such as snow or dust) and the frequency at which cleaning is performed.
  • Shading- Shading is the blockage of radiation caused by trees, buildings, terrain, and other structures within the surrounding environment. The impact of shading on the power output of solar installations is dependent.
  • Mismatch and Inverter Efficiency- An incompatibility between the modules could cause a loss in performance. Additionally, the efficiency of conversion takes a huge loss when the input power is lower than the power of the inverter.
  • Age- Solar panels generate less energy as they grow. In general, the decline in performance is thought to be approximately 0.5% per year.

What is an SEAI grant and how will it help me secure a Solar PV System?

SEAI grants help homeowners, businesses, and large industries and communities cut their energy bills and greenhouse gas emissions to install solar PV systems in Ireland. The Irish government offers a grant for solar PV systems, which can cover up to 50% of the cost of installation. Solar PV systems in Ireland are a great investment, and they can pay for themselves in just a few years.This grant for solar PV can help you set up Solar PV panels at your home to generate renewable energy. SEAI offers €900 per kWp, up at 2kWp. €300 per additional 4kWp up to kWp, and a total Solar PV grant capped at €2,400.Before you pursue an SEAI home grant for solar PV and decide to install a Solar PV System in Ireland, contact a solar installer today to learn more about solar energy and how it can benefit you.
