8 months later we asked Gordon: "Are you happy with the performance of your system so far?"

The only problem is the voltage in the street ( that supplied by the nearest transformer ).
As the solar system starts to kick in ( along with every body else ) the voltage in the street climbs up from 240 volt to 250 to 255 volts
the inverter has to start shutting down to avoid over voltage in the street, hence forth limiting your export capacity.
Who knew?

The installation was quick and efficient with REC panels and Fronius inverter 5kW system. Colin is not pushy like most of the other salesmen we came across. He was always happy to answer my questions, an easy to talk to a down to earth operator who left as feeling extremely happy with our choice of PV system and installer. our system was installed in January 3 weeks ago since then the max it has produced in a day was
28kWh and the minimum on a rainy day was 13kWh it seems to average 4.5to 4.8 kW at peak production time (between 11am and 2 pm) and some times it has produced up to 5,6kW in peek production times. I highly recommend Colin.

My system is going to be installed 14th June. I started with some cowboys and inflated prices, to your recommended people, and then worked my way through them. I came up with SE batteries as I had contacted them a couple years ago when I first thought of idea, but then things were a lot dearer.

Colin has called in a few times to answer my queries etc. Always been available to work through my ideas and to get the best system for my requirements.

Yes over and above. Have not had a bill since they were installed, even have had a $535.00 rebate from AGL
