Companies from a range of sectors have backed calls from the solar industry for urgent changes to Scottish planning law and tax rules.
More than 20 firms and trade bodies have written to ministers arguing that business rates and permitted development rights must be reformed.
A joint letter states that businesses are currently “unable to deploy solar energy at the necessary speed”.
It argues changes would help firms cut energy costs and decarbonise.
The signatories include representatives from agriculture, warehousing, distilling, food and solar.
