Domestic Solar Panels 39% Cheaper Than in 2020

The cost of getting solar panels for your home has plummeted in the past five years, with a 39% reduction in the price per kW of capacity since 2020.

The Home Solar PV Report 2026 compiled by EnergyEfficiency.ie shows that in 2025 it cost most homeowners receiving the SEAI grant €1,689 per kW. That’s a massive drop from €2,762 in 2020.

The average price for a home solar PV system last year was €10,554. This hasn’t changed substantially over the previous five years. But what has changed is what people get for their money.

In 2020, the average capacity of a home solar PV system was just 3.7kWp. By the end of last year, that had increased to 6.23kWp. That’s nearly double the power output, delivering vastly greater savings.
