What our customers say
Reviews from real Mackay businesses and homes.
After getting a few quotes, We decided to go with Next Phase Solar and we're really glad we did. They were upfront, easy to deal with, and there were no surprises along the way. Install day went smoothly and everything works perfectly!
Very pleased with the whole experience, right from quote to saving money with no more electricity bill. The quote was very competitive and the job was done in timely manner. Would recommend Brad and the team to anyone thinking of solar.
Really good value. I wanted to add a battery to my setup and shopped around a fair bit, and Brad came back with the best price out of everyone I asked. No pushy sales, just a straight good deal and the job done properly. Happy customer, would recommend them to anyone in Mackay looking at solar or batteries.
I would highly recommend Next Phase Solar. From first contact, to install and then aftercare they've been friendly, helpful and professional. The system is performing well and I'm happy with the outcome!
Really happy with my new solar panels at home. The whole thing was smooth and stress free, and they took the time to explain everything and answer all my questions, which I really appreciated. Great service and lovely to deal with. Thank you.
Fast and easy from start to finish. I just needed a battery added and they sorted it out really quickly, much faster than I expected after hearing how long other companies take. Brad was great, clear and helpful the whole way through. Highly recommend them if you are in Mackay.
Could not be happier with my solar installation. I got quotes from several companies, since there are loads of them around and the market is competitive, and NPSolar honestly gave me the best price by far. I had also read plenty of reviews of other companies and they all seemed to take months to actually get the job done. NPSolar installed my 14 panels and batteries in a single week, at the best price, which felt almost too good to be true. Huge thanks to Brad, who was friendly, talked me through all my questions and made the whole process easy. If you are in Mackay and looking at solar, definitely get a quote from them.
