Solar collectors: How they work

Capture the sun’s energy efficiently for heating and power solutions

Solar collectors in Ireland

Solar collectors, also known as thermal panels, provide an efficient way to harness the sun's energy to heat water for homes and businesses.

These systems reduce reliance on traditional heating methods, lowering energy costs and carbon emissions. With government incentives and long-term savings, solar collectors are a smart investment for homeowners looking for a renewable heating solution.

How solar collectors work

Solar collectors absorb heat from the sun and transfer it to a fluid that circulates through the system. This heated fluid is then used to warm water, which can be stored in a tank and distributed through radiators or underfloor heating systems.

Unlike photovoltaic solar panels that generate electricity, solar thermal systems focus solely on heating water, providing a reliable and sustainable solution throughout the year.

Benefits of solar thermal panels

  • Lower energy bills: Using solar collectors reduces dependence on gas or electricity for water heating, leading to significant savings over time.
  • Renewable and sustainable: Solar thermal technology relies on an abundant and free energy source, reducing reliance on fossil fuels.
  • Reduced carbon footprint: By switching to solar heating, homeowners can lower their greenhouse gas emissions and contribute to a cleaner environment.
  • Government incentives: Grants and financial support from the Sustainable Energy Authority of Ireland (SEAI) help reduce installation costs, making solar thermal systems more affordable.
  • Low maintenance requirements: Solar collectors have few moving parts and require minimal upkeep, ensuring long-term efficiency with little effort.
  • Efficient heating all year: While solar collectors perform best in sunny conditions, they can still generate heat even on cloudy days, ensuring a steady supply of hot water.

Installation and costs

The cost of installing a solar thermal system depends on the size of the system and the complexity of the installation. Prices typically range from €3,000 to €7,000 before grants.

SEAI grants can help reduce this expense, making it a cost-effective investment for many homeowners. These grants encourage the use of renewable energy and help offset the initial installation cost.
