What Our Customer Says
Vitan Shah2026-10-12Trustindex verifies that the original source of the review is Google. Fantastic experience with GreenLight Energy Solutions retrofitting a 42kW battery system to our existing solar. The quote was competitive, communication was clear, and the installers did an immaculate job integrating the new tech with our current setup. The system is performing brilliantly. If you want to upgrade your existing solar with serious battery storage, look no further. Highly recommend! Jon Tiddy2026-08-17Trustindex verifies that the original source of the review is Google. Great experience dealing with Kunal and his team. Perfect panel and battery design and great, clear communication made the process smooth and efficient. A pleasure to deal with. ROY2026-04-03Trustindex verifies that the original source of the review is Google. Thank you so much to the whole team at Greenlight Energy. From the start when i enquired to the whole installation process it was seamless and easy. The boys that completed the work were very helpful and informative around the whole process. They were very fast and also cleaned up after themselves and left the place as it was when they arrived. Thank you again for a great installation! Mohamed Omar2026-03-31Trustindex verifies that the original source of the review is Google. Very professional service. Installed 2 solar systems and batteries between residential and business. Always recommend gor my friends. Vivek Shettigar2026-03-22Trustindex verifies that the original source of the review is Google. Couldn’t be happier with Greenlight Solar in NSW. The team installed a Fox 42kW battery paired with a 10kW inverter, and 6.6kW along with DC coupling my old system to additional string and the quality of work was excellent. Everything was done efficiently, and the installation was very clean and well-organised. Kunal stood out in particular—he was honest, upfront, and gave clear advice with no pressure. It’s rare to find that level of transparency these days. Overall, a fantastic experience and I highly recommend Greenlight Solar!

Excellent service by everyone involved Tapan and electricians everything was organised and installed to perfection on the Gold Coast Queensland Long Le2025-09-25Trustindex verifies that the original source of the review is Google. Andrew from GreenLight Energy was likely the most authentic and transparent sales representative I've ever spoken to. He took the time to answer all of the questions I had and provided valuable insights to help me maximise the return on investment. There was never any pressure to proceed, and it was clear that he was purely focussed on helping me make the best decision, rather than just getting a sale. If you're looking for an honest installer who will go the extra mile to make sure you're getting value for money, I'd strongly recommend GreenLight Energy. Edwin Moniz2025-08-14Trustindex verifies that the original source of the review is Google. We installed a Sungrow solar battery 4 weeks ago to our existing 5 year old solar panel system through Greenlight. On both the occasions my experience with Greenlight has been very positive and satisfying. From design to quoting to the installation evrything has been flawless and without any stress. Amanda was amazing during the design and quoting process. Even though we went through a few changes, every change was done obligingly and promptly. Kunal, with his wealth of knowledge and willingness to share and steer you towards the best possible outcome has been instrumemtal and we ended with a "bang for our buck" system. In the 4 weeks since the system was put in, even though we had a majority of cloudy days, our projected bill for this quater has dropped from around $1200 to just around $700. Extermely happy with our experience with Greenlight and Kunal and would highly recommend them.

How Solar Energy Works?
Curious about how solar energy works? It’s simple! Solar panels installed on your roof capture sunlight and convert it into electricity through a process called photovoltaic (PV) conversion. This electricity is then fed into an inverter, where it’s transformed into a usable form for your home or business.
Any excess energy produced can be stored in batteries for later use or exported back to the grid. With our state-of-the-art technology and expert installation, you can harness the power of the sun to reduce your reliance on traditional energy sources and save on utility bills.
