Ann: Record Revenue and Profit , page-6

In Solco's defence,
1. they are mainly a Western Australian company (allbeit one that is now expanding vigorously into the eastern states and Pacific)
2. WA only brought in its 40+7cent FIT in July
3. Wholesaling a commodity is always going to be a marginal business unless the wholesaler can add value.

SOO is starting to try to add value with product testing (undoubtedly expensive and always necessary as new panels/inverters/suppliers come on stream), project design and management. With luck they will soon start to look like the solar business of CBD.
