5 Star Review - The Sun WorksRecently Sun Works put a 5 kW Fronius inverter and 20 REC panels on our house. This was recommended after a site visit and various options were canvassed. Within a week of this visit the work was done – old panels removed, new ones put up and the inverter connected to our supplier. Paperwork took five minutes and our iPad app was connected to the inverter so we could be gratified about what we we making each day. None of this would be possible without Sun Works great team – Mike, Peter and Wayne, not forgetting their hardworking panel installers crawling over and under the roof. Each man is a expert and a pleasure to deal with personally, by email or on the phone. You might think all this ‘over the top’ but this is the third house Sun Works have done for us. This speaks volumes for these men and their company – 100% satisfaction guaranteed. Thank you once again!
