Our work

See what our customers are saying about us

G-Solar were very efficient in their process from initial site visit, organising finance to job completion. The tradesman were respectful of our clients and did an excellent job. We are loving the benefits of Solar with our power bills less than half of what they were before

G-Solar Designed a 30kW system for our industrial workshop. Having primarily a daytime load we were an excellent candidate for solar. We are now saving 80% on our electricity costs and couldn't be happier

Great advice & excellent Installation. I will definitely be using G-Solar for my next Solar System.

Grant and the team from G-Solar did a great job. Grant made the solar process very easy with a no fuss approach. His savings estimates were very accurate and everything was explained to us along the way. We went with the Solar Finance option meaning we did not have to pay a cent for the solar up front. Our savings are much greater than our repayments and in 3 years the system will be paid off. Very happy with the service

Honest sales advise. Neat and tidy installation. I have recommended G-Solar to many of my friends & colleagues.


G-Solar designed an 8kW system for my house in Port Douglas, the process was very easy and the electricians were very polite and did an excellent job of installation. I am now saving over $500/quarter on my Electricity Bills.
