Solar power has emerged as a vital component of Ireland’s energy transition, helping reduce carbon emissions and dependence on fossil fuels. However, the quality of solar installations plays a significant role in harnessing the full potential of this renewable energy source. In Ireland, many of solar installations fail on their first inspection by the Sustainable Energy Authority of Ireland (SEAI). We’ve been quietly delighted, having recently discovered Caldor Solar defies this trend with an impressive pass rate of upwards of 85%*. We do, in part, put this down to that fact that we specialise exclusively in solar since 2015 and we do not sub-contract. Armed with this information, we thought we would explore the importance of quality work and the significance of choosing the right solar installer in Ireland.

SEAI Pass Rates

To give a little context, the pass rates are based on the inspection processes set out in the Quality Assurance and Development Programme (QADP) available on the SEAI website. The QADP sets out how SEAI manages quality, inspections and compliance.

The pass rates below include Severity 1, 2 and 3 non compliances which include those related to the solar PV installation as well as all related grant related documentation, health and safety related documentation and inspection related documentation.

The Rising Demand for Solar Installations

The demand for solar installations in Ireland has skyrocketed in recent years. As individuals and businesses recognise the environmental and financial benefits of solar energy, the number of installations has surged. However, with this increased demand comes a higher risk of subpar workmanship and installations that fail to meet the necessary standards.

The Importance of First Inspection by the SEAI

The SEAI plays a crucial role in ensuring the safety and effectiveness of solar installations. As the regulatory body responsible for promoting sustainable energy practices, they conduct thorough inspections to verify compliance with industry standards and regulations. Unfortunately, a significant number of solar installations in Ireland fail their initial inspection, highlighting the prevalence of occasionally poor workmanship and inadequate attention to detail. That said, there’s a reassuring aspect to consider —if an installer’s pass rate drops below a specific threshold, they risk removal from the SEAI SPV register and are ineligible to apply for grants on their client’s behalf. If a company cannot facilitate the SEAI grant for you, it’s advisable to investigate the underlying reasons
