I recently had a 30kw battery system with 24 x 475kw solar panels and a 12kw Inverter installed at my new house at Baldivis. Solar365 did a great job for me. I have yet to receive the first bill but Solar365 were very helpful with the supply and Installation. Bob Drysdale
Solar 365 did a fabulous job installing our solar panels here in GERALDTON. They travelled all the way from PERTH and delivered top-notch service — at half the price of other quotes we received. We’re extremely happy with the value and the outcome. Roger from the Solar 365 team was fantastic to deal with — professional, friendly, and made the whole process smooth. Big thanks to him and the crew for making it happen. Just one small suggestion: please remind your team to be a bit more careful when walking on tile roofs. Other than that, everything was spot on. Highly recommended!
I had an excellent experience with Solar 365. From the moment I signed with them, everything moved quickly and smoothly. They installed my Sigenergy battery within just 3 days, which honestly exceeded my expectations. The team was professional, well-organised, and kept me informed throughout the process. The installation was neat, efficient, and hassle-free. This was a huge contrast to my previous experience with Solar Maxx, where I waited almost 6 months with no clear communication or resolution. Switching to Solar 365 was the best decision I made. If you’re looking for a reliable solar company that actually delivers on their promises, I highly recommend Solar 365.
Excellent service and quality install. Had a 6.6 kW solar system with 10 kWh battery installed by Solar 365. Process was smooth and professional. Great communication and very neat workmanship. System performs as promised and my electricity bill has dropped to $ zero.
Solar365 team were great! Rahul was super helpful from start to finish (way quicker then we expected), great customer service, explained everything and was upfront about all costs and services. From rebates getting approved to installation was only 4 days. The install team were great, had excellent attention to detail, and a fantastic sense of humour.
