The group owes about $2 million to the Australian Tax Office.
The company specialised in installing large solar panels on big projects and used a mostly casual workforce.
Mr Yeo said it entered administration with no cash to keep employees, who were all stood down on Tuesday.
“We and the directors are in conversation with various contractors and project owners in an attempt to try to transition employees wherever possible,” he said.
“This is going to cause some people disruption or hardship as some employees and subcontractors are working in very remote and regional areas, so we are doing what we can to find them some alternative options.”
The first creditors’ meeting was expected to be held late next week.
Of the total job losses about 100 of them were expected in WA, where construction at Alinta and FMG’s Chichester solar farm is ongoing.
An Alinta spokesman said it was too early to comment but they were monitoring the situation closely.
In November 2019 Facebook page Farm Work Australia placed a notice on its page to its 84,000 followers for workers at the Kiamal solar farm.
The post spruiked the roles as casual, 10 hours a day, six days a week for a flat rate.
Shared accommodation would be provided and the role was eligible for a 417 visa extension.
