Read moreWe recently got a Deye brand battery which worked with our existing solar panels. Great sales service. We had a few hiccups which were discussed with the company and rectified. I thought that was great and part of why a local smaller company is good to deal with as if there are any issues you can actually discuss it and get a resolution. I would and have recommended MJJs solar.

Read moreWe had our system installed by MJJs 6 years ago. The inverter recently died and they had it replaced under warranty and back up and running in two weeks. Brilliant service. It's absolutely worth going with an established local company rather than the cheap subcontractors that drive up from Sydney.
