Why now

Ireland is in the middle of a rooftop solar boom. The earlier you move, the earlier you're generating.

1 GW of solar went up in 2025 alone

Ireland connected around 1,005 MW of new solar in 2025, more than double the year before. Rooftop systems passed 1 GW across 170,000+ homes, farms and businesses, and the national target is 8 GW by 2030.

The practical read: installer capacity and ESB grid connections are the queue that matters. Movers get connected, and generating, first. More than fifty of those roofs are ours.

In their words

Sustainability managers, GMs and facilities leads on working with MarVal.

"A proven track record in delivering commercial-scale energy technology. From planning through construction and operation, the MarVal team were highly organised and efficient."

Kelly Garvey EHS & Sustainability Mgr · DGD Shredding

"An 800 kWp install on a working recycling site is no small feat. MarVal worked around our trucks for the entire install. Zero disruption."

Paul Daly Operations Director · Panda Recycling

"This collaboration represents our commitment to delivering exceptional hospitality while minimising our impact on the environment. The seamless integration into our operations was outstanding."

Greg Doyle General Manager · Brandon House Hotel

"A 5-star heritage estate is a tough brief. They designed a 66 kWp install that's almost invisible from the visitor approach. Discreet and effective."

Stephen Hayes Estates Manager · Powerscourt Distillery
