I was after a battery system for my house but kept putting it off due to lithium battery concerns. These issues were resolved and I purchased a system. I found the interaction from the salesperson to the installers to be punctual and a pleasure to deal with.Posted on Google![]()

Amazing service, quick quote, easy to understand. Came out within a fortnight, had it done within the next fortnight. Process was smooth. Lachlan in sales was very informative and helpful. Jaiden and the boys were exceptional, we have had extra questions and they are still as helpful as ever. Very happy would highly recommend for anyone looking at getting or upgrading their solar. We got other quotes from solar companies closer to us and they were not helpful at all.Posted on Google![]()

There was an initial delay because of a supply problem, I was informed. On the qsecond day they arrived at the time they said they would and answered all my questions. The job was finished within the time frame we had discussed. They removed all the rubbish, they workers around my numerous garden beds. They were professional and polite at all times. I would highly recommend themPosted on Google![]()

I couldn’t be happier with my experience with Nexgen Solar Solutions, especially with Corey. From the very beginning, the boys were incredibly helpful, professional and genuinely took the time to explain everything to us and answer all of our questions. The whole process was so easy and stress-free, and Corey kept us informed every step of the way. Highly recommendPosted on Google![]()

We recently had our solar panels installed by NexGen Solar Solutions, and we couldn't be happier with the entire experience. Corey and his team were professional, friendly, and efficient from start to finish. Corey is extremely knowledgeable and took the time to answer all of our questions, making the whole process easy and stress-free. The installation was completed to a high standard, and the team was punctual, respectful, and great to deal with. We highly recommend Next Gen Solar to anyone considering solar. Thanks again to Corey and the team for the excellent service!
