All the quotes are very reasonable for this size system and use good-quality equipment (particularly the REC Alpha Pure, which is a very high-end panel).

Both the SolarEdge and Sungrow inverters are hybrid inverters meaning you can easily add a battery to either system in the future.

Adding an EV charger is also no issue with any of these systems.

Good luck. Feel free to post photos if you go ahead.

Thanks for the response so far. I have received an additional quote which is for a microinverter solution.

It is as follows

Option 4
Solar Panels
Brand: Canadian Solar (CS6R-440T)
Quantity: 26
Total Capacity: 11.4kW

Inverter
Brand: Enphase
Model: 9.36 kW IQ8AC Microinverter

Price: $15,825

I know there is a lot of debate about string Vs microinverters. I am currently leaning towards Option 3 above and wondering whether the extra $3,000 is worth stepping up to a microinverter based solution.

Micro’s are a great option for complex roof-lines and frequent shading but I wouldn’t bother if you don’t have these issues.

I’d go with option 3 as well. Just check up on the installer and ensure they have a good reputation. Local installers are always the best option.

Thanks for the contributions so far. We are getting close to a design. The thing that is outstanding is surrounding panel tilt.

The house is based on the northern beach of Sydney and faces East-West. We have a large flat roof section that panels will be installed onto. As I see it there are three option.

  1. Installed flat
  2. Installed with a 10-20 degree tilt facing north
  3. Installed with a 10-20 degree tilt with East-West tilt orientation.

Our energy usage is double in Winter to that of Summer due to pool heating.
Option 2 seems to be the obvious choice, however it will result in 1 row less of panels to the other configurations.

So am leaning toward option 3, which is $1200 more. Keen to hear thoughts on whether its worth it.

much appreciated.
