28/01/2026 — Andy and his installation team completed my solar and battery installation, which was a fairly large and somewhat complex job. They approached every part of it with absolute professionalism, skill, and a genuinely positive attitude. The entire project ran smoothly from start to finish. The team worked incredibly hard, were courteous throughout, and delivered a result that more than met my expectations. I would definitely recommend them.

My experience with the Opera Solar Energy team has been very satisfactory. I first engaged them to install a complete solar system (panels and battery) in July 2025. Andy was helpful with the proposal as well as explaining the location where the solar panels and the battery should be installed. The installation team carried out the work so neatly including clearing out any rubbish afterwards. Since I had a great experience with the Opera Solar Energy team, I engaged them to install a solar battery for my son's residence in December 2025. My son was also satisfied with their work.

I am really happy with my new Solar battery. It was installed easily in one morning and the team at Opera Solar were fantastic.

We had a 16 kWh Solar and battery storage system with 54 panels installed by Andy which was operating successfully for eleven years, due to external damage the system had to be replaced. Acting on advice from Opera Solar Energy (Andy) it was decided to upgrade not only the panels but also the back up battery to a latest technology Sigen 40kwh storage unit. Due to the professional advice from Opera solar Energy and of course Andy's help and support we now have a system which is virtually independent of the grid. Since the date the solar system was professionally installed and commissioned by CEC accredited installer, monitoring records prove we have not had to rely on the grid for power. We thank Andy for taking our needs into account and giving us a system which gives us the best possible solaar system at the best competitive price. Thank you ANDY. Highly recommend going with Opera Solar Energy for all your solar and battery needs.

Andy and the team at Opera Solar were fantastic to deal with and we couldn't be happier with the service and install. The install team were able to work in the limited space we have to install the inverter without impacting our side access which was a huge plus for us. Top quality work!

I recently had a 13.3 kW solar PV system installed by Opera Solar, consisting of a 10 kW Sungrow inverter and a 16 kW backup battery. Andy, my system designer, was exceptionally patient throughout the process, accommodating multiple changes to the system configuration to align with my brand preferences and budget. He took the time to answer all of my questions thoroughly, including those raised over weekends. The installation was scheduled just seven days after accepting the quote and was completed on the agreed date. Allan and his installation team delivered an excellent outcome, completing the work by 1 pm and ensuring I had full access to the Sungrow app to monitor the system. Allan also went above and beyond by replacing a damaged roof tile at no additional cost. Following the installation, Andy walked me through a practice system power-down and power-up procedure, ensuring I was confident operating the system. Atul from the accounting team promptly provided the necessary documentation to support the upgrade to a smart meter. I would confidently recommend Opera Solar for their efficient delivery, professional workmanship, and highly personalised service.

Thank you so much Opera Solar Energy for a great product & excellent communication. Andy was very efficient & easy to deal with a great government rebate. Definitely recommend for anyone looking at a new solar or upgrading your existing solar system.

If you ever want to experience what it’s like to chase a solar installer the way a pilot chases a tailwind, give Opera Solar in Baulkham Hills a try. The owner has mastered the ancient art of not answering calls. I’m convinced he teaches seminars on it. You can ring once, twice, ten times… nothing. Not even a courtesy “busy, call you later.” The man communicates exclusively through WhatsApp like he’s running an underground spy operation, except less responsive. When you do manage to get a reply, prepare yourself for a level of arrogance that could power its own battery system. Simple questions get treated like you’ve interrupted him during the lunar eclipse he’s been preparing for. All I wanted was solar, not a one-man disappearing act. If you enjoy guessing games, WhatsApp blue ticks, and the thrill of wondering whether your installer is still alive, then Opera Solar is perfect. Otherwise, I’d look elsewhere… preferably somewhere that owns a phone and knows how to use it.

I highly recommend Opera Solar Energy to anyone. The team, lead by Andy is very efficient. Andy came out and design and quoted the system I needed. Then arrange the installation date ASAP. The team of installers came out and they were very informative explaining the installation process. The installer had an eye for detail so that the system conduit was not an eyesore. The whole process took a week to have the 8Kw system with battery installed. I am so happy with the solar system. Also, after a bad storm, there was an issue with the battery. It only took one call to Andy, and his team were able to fix it within an hour. For efficient, quality and workmanship I will recommend Opera Solar Energy, to anyone.

I highly recommend Andy from Opera Solar. What distinguishes Andy from the pack in a very crowded space is his personal service and customer focus. He genuinely cares and wants to build a strong customer relationship and experience as is evidenced by my personal interactions with him. He's knowledgeable and isnt just after a quick sell which is another strong reason why you should not only strongly consider him but put him on top of your list. I would recommend Andy and Opera Solar to anyone looking for solar panels or full solution including battery. Keep up the good work Andy .
