Mark Group, Solgen merge in move to corner Australian rooftop solar market

Rooftop solar installer Mark Group and commercial solar business Solgen have merged, in a bid to capture a leading share of Australia’s booming rooftop solar market.

The two companies announced last Thursday that Mark Group had bought Solgen, describing the merger as a logical fit, with Mark Group established as a market leader in residential solar installation and Solgen a clear market leader in commercial and Industrial solar PV.

Among Solgen’s most notable efforts in Australia is the City of Sydney project – a $6 million contract to install 1250kW of solar PV across 30 council cites, which Solgen won over rival bids from Ingenero and SunPower.

Most recently, the company won a contract to install a 1.17MW solar PV system on the roof of the short-term car park at Adelaide Airport.

“This merger combines two great businesses with talented people, great customer solutions and a suite of high quality brands,” said Mark Group CEO David Brown.

“Together we provide a scale and level of expertise that allows us to deliver on our strategic intent to be THE leading provider of quality renewable energy solutions in the region.”

Solgen’s founders, David Naismith and Joe Coco, will continue as shareholders in the combined Group, and will remain as directors of Solgen Energy while also joining the senior executive team of the combined group.


“We share the passion and vision of the Mark Group team to be the leading renewable energy provider in the region,” said Naismith.

“The combination of these businesses immediately enhances the scale and capability across the group. Our combined industry experience positions the group for significant growth opportunities as the solar industry matures to become a critical element of the mainstream energy market.”
