There are a couple of self-employed solar panel installers in The Grove so we could possibly organise a panel discussion or similar.
A friend of is also going through the evaluation process in some depth and he might also be willing to contribute his findings.
There are some ‘bulk-buy’ deals set up through other Transition Groups (Samford and Kurilpa) that may help with getting good advice and a good price.
Setting up a ‘bulk buy’ deal for The Grove might also be a project worth considering.
