Matt Alexander’s Solar Energy Success Story

A 5-Star Review of NXTGEN Energy’s Products & Services

The work’s been done to an incredibly high standard. The cabling is really neat, the system is performing fantastically well, and we can’t believe how much money we’ve saved already. So, generally a big thank you to Stuart and Kelly and everyone at the NXTGEN team, who have done a really, really good job from start to finish.

We really couldn’t be more pleased.

Commercial Solar Panel Installations

Commercial solar panels are a smart way to reduce your energy bills, lower your carbon footprint and secure your future energy supply. By installing solar panels on your roof or land, you can generate clean and renewable electricity to power your business operations. You can also benefit from the Smart Export Guarantee (SEG) which pays you for the excess electricity you export to the grid. Commercial solar panels can help you save money, protect the environment and enhance your reputation as a green business.

Residential solar panels can help you save money, protect the environment and become more energy independent in these times of a cost-of-living-crisis. Now is the time to go solar!
