5 Star Review - The Sun WorksOnline, via phone and face to face I spoke with a lot of solar providers before settling on SunWorks. I spent a lot of time trying to pin down exactly which combination of inverter, panels, etc made the most sense for us. After a fortnight I realised that Mike had suggested on day one the exact set-up that it took me 2 weeks to piece together. A further two weeks and everything is in place and singing: utterly professional, friendly and the most price competitive (frankly he didn’t need to be). Recommend highly and without reservation. Thank you Mike and the team at SunWorks.
