I got several quotes for my 3kW system. Sunstainable were not the cheapest, but they were offering quality products with a longer sustained performance and they would work with my schedule rather than me having to work with theirs.

Installation was smooth. The two guys that came out were polite and kept the promises they made in terms of timeframes and outcomes.

After installation I got a call to ensure that I had submitted the paperwork for the premium feed in tarrif. There was nothing in it for them to do this and I thought it was a nice touch.

I have had two systems installed at two properties. One by sunstainable and one by a cheaper company. I would pay a bit more for these guys because you get what you want and they are much simpler to deal with.

18 months in and there has not been a problem with the system and it us performing as well as it did on day one.
