Solar Panel Installation Sydney | Isolux Solar

I recently had a fairly complex solar installation completed by ISOLUX Solar, and overall I’m very happy with the outcome. The scope wasn’t straightforward - it involved relocating existing solar panels to a different section of the roof to enable other roof works, and then installing a brand new 13.3kWh system along with a battery and dual inverters. In total, the setup includes 48 panels, two inverters, and a battery system. What really stood out was the on-ground installation team. Their professionalism, attention to detail, and work ethic were excellent -- they genuinely went above and beyond my expectations. A special mention to Shivam, who stayed on top of the entire process from start to finish and ensured everything was delivered properly. To be fair, there were a few challenges. Communication wasn’t always smooth, likely due to the back-office team being offshore. There were also some last-minute changes (including one late evening on a weekend), and the invoice was sent just before installation requesting full payment, which wasn’t ideal. Additionally, there wasn’t always a clear single point of contact, with multiple people engaging from overseas. That said, the quality of the on-site execution more than made up for these issues. The final result is exactly what I needed, and the system is performing as expected. Overall, despite a few process-related hiccups, the delivery exceeded expectations, and for that reason, I’m happy to give 5 stars.

I had solar panels installed by Isolux in 2022 and have been very pleased with their performance ever since. Based on that positive experience, I chose to include Isolux when seeking quotes for a battery system. Gary Smith was courteous and professional throughout the process. He provided a highly competitive quote, better than any other I received, and maintained clear, consistent communication, keeping me informed at every stage. The installation was scheduled with minimal delay, and everything went smoothly on the day. The battery system has been performing well, and I am optimistic about seeing even greater savings on my next electricity bill. I highly recommend Isolux and their team for their competitive pricing, excellent customer support, and quality workmanship.

Great experience with Isolux from start to finish. Mark Jones was professional, transparent, and made everything simple. Haider did an excellent job with the installation. He’s patient, efficient,, and very professional. What really stood out was their customer-first approach and clear communication throughout. Highly recommend Isolux for anyone considering solar or battery installation.

Mark Jones helped us choose our system and organise a very quick install, which we really appreciated. He kept us well informed throughout the process. We initially went to him after he organised a solar and battery install for a friend of ours. The trades team, including Matt, installed solar and a battery for our terracotta-roofed home. They appeared to know what they were doing. They were also accommodating to our vision and were “easy to work with,” according to my husband, which we valued. The Level 2 tradesman who finished everything off was particularly helpful and informative. It’s still early days, so we’re yet to see how it performs long term. That said, we’re grateful to have it installed and are hopeful it will provide many years of reliable use. Thanks to everyone involved for the effort.

Very clear communications, I was updated when any changes were made. Installation was seamless, set up & running as designed on the day & no mess left behind, all rubbish taken away.

Wonderful service. Gary had us quoted and booked in for install super quick. The guys did a wonderful job. We had an issue with ausgrid and being on a over 50s embedded network. But they sorted it out we are up and running. Thank you Gary for all your help.

Within 10 days of my enquiry, Mark Jones and his installation team had my solar and battery installed and commissioned. Since I had already done my research and obtained several quotes from other installers, the quote offered to me by Mark based on my requirements was competitive without me having to get into hard negotiation on pricing. He was also very patient promptly answering my questions. Matt, Prem and Roshan from his installation team did a wonderful and neat job, and were very friendly. It was a good experience dealing with Mark and team.

Am so happy with the battery purchase and installation just completed by Isolux. The team were so professional and helpful in providing battery options as well as being very price competitive. The installation went so smoothly and I could not be happier with the whole process. I fully recommend using Isolux for anyone looking to buy a house battery.
