ALDI complete solar retrofit at Mayo store

ALDI Ireland has announced a €5 million investment in green, energy-efficient solutions, marking a major step in the retailer’s ongoing sustainability journey.

As part of the national installation, the Belmullet store in north Mayo has received a major solar panel retrofit, successfully completed today.

The initiative will see solar panel installations begin in 2025 at 22 selected stores, including the Belmullet store, with an additional 22 stores scheduled for installation in 2026. In total, the €5 million programme will retrofit 44 stores over the next two years.

Once installed, each system will comprise of 288 solar panels and is expected to generate an average of 100,000 kWh annually - the equivalent of powering a washing machine for over 1,000 cycles, which covers approximately 30% of each store’s electricity consumption.

This move is part of ALDI’s broader commitment to finding greener, more energy-efficient solutions that reduce environmental impact and support long-term cost management.

ALDI’s partnership with Greenvolt Next Ireland is a strong example of how strategic investments in renewables can benefit both the bottom line and the environment. The growth will allow Greenvolt Next Ireland to bring on new contractors to support ALDI’s rollout nationwide.

This investment is projected to double Greenvolt Next’s retail PV sector output in 2025, positioning the company for further growth across Ireland and strengthening its position as a leading renewable energy supplier.

Greenvolt Next, supported by Greenvolt Group, provides businesses with decentralised renewable energy solutions, including solar and electric mobility, among many others.
