UPDATE JUNE 2020
Very happy with the install we had 41 solar panels installed in the middle of February.
41 x 300 W sunpower panels with two Fronius 5 kW inverters. 13.2 kw system. We also purchased monitoring which I would highly recommend.
we went through Widgery And Wilson electrical, I would recommend them, they did a good smooth install and helped us out with some high voltage problems that we had initially. We had one small issue with one of our electrical items not being monitored correctly and after we figured that out they were quick to rectify the problem. Their quotes were very detailed and offered a lot of information. They have been around for a long time and they do a lot of commercial solar and some retail.
I wouldn’t do anything different except perhaps to buy more solar panels because we purchased a small outdoor spa just before the solar panels arrived and it was therefore not included in our quote (and not included in our payback period which is at 3.5 years) so we would have a slightly higher payback period now because of the spa purchase.
33.88 c/kWh peak
20.9 off peak
I’m not sure whether to recommend red energy or not really I don’t know much about the other retailers in comparing them. I do get other quotes occasionally from other retailers but they can’t match the 15% off pay on time discount that I get at red energy (which red don’t offer this any more).
Today we are producing 5.4 kW of power in the middle of a clear sky sunny winter day so I would definitely recommend solar panels even though there is less solar gain during a cloudy day the solar we do produce on a cloudy day does still cover part of the running of the house.
The inverters don’t take up much room and the solar panels don’t look too bad.
