New regulations moved last year, requiring many new systems to obtain building permits, were slow to filter through to retailers and installers, creating confusion in the industry.

In response, Workplace Relations Minister David O'Byrne will extend an exemption on systems up to 38 square metres from needing a building permit, up from 18 square metres.

Mr O'Byrne said the new rules struck the right balance between the compliance burden and public safety, and would give consumers greater flexibility.

Jessups Solar Squad managing director John Thurgood said it would now cover most systems.

``Appropriately the cost burden will not severely impact the local dealers or consumers getting council approval,'' he said.

Installer Adrian Luke agreed, but said the communication lines to industry needed to be open. ``It's a big move forward but it would never have gotten to this point if they actually consulted someone in the industry,'' he said.  ``But you've got to praise them for being reactive.''

The changes could take effect as soon as next week, once they are tabled in Parliament. 

The move comes after many readers shared their stories of delays, extra cost and confusion with The Examiner   over the past fortnight.

Greens Bass MHA Kin Booth, who campaigned for the change, welcomed it  as ``a step forward in removing worthless regulations''.
