Their Solar Story
Running a small business from home, our electricity costs were getting out of control. We were paying close to $1,100 per quarter and it was only getting worse. We decided to go solar after a friend recommended Smart Solar Group.
What impressed us most was the honesty. Unlike other companies who quoted us systems that were way too big, Smart Solar Group actually recommended a system that was right for our usage. They showed us the data and explained exactly why a 10kW system was the sweet spot.
The installation team were outstanding. They worked around our business schedule, were respectful of our property, and the workmanship was impeccable. Everything was neat, tidy, and professional.
Six months in, the system is actually performing above the projections they gave us. Our quarterly bill is now around $120, and we are even getting decent feed-in credits. That is a saving of nearly $4,000 per year.
If you are in Mackay and considering solar, do not look past Smart Solar Group. They are the real deal.
