This is a reassuring website. I don’t have much idea what’s good or not, only what I’ve found over the past 2 weeks. Please I invite your opinions.
I’m in Central West, NSW. Below is an aerial view of the house (with sun from the north at the top of the page). You can see the proposed panels on the roof.
The following has been recommended:
System size 4.8 kW DC (STC)
Estimated annual production 7,436 kWh
Solar panels 16 × 300W Hyundai Green Energy RG Series - HiA-S300RG 1640 mm × 992 mm · Monocrystalline
16 × Enphase IQ7-60-5-INT · 240 W
1 phase · 97.6% max efficiency
System efficiency 87%
For a Total price of $8,500 AUD (including GST minus STCs). Includes installation and monitoring.
I realise its expensive - most systems have been quoted at between 4 and 5K over the telephone. The cheapest was $1800 (yikes)! But the installer I’m dealing with (who came to the house) gives me confidence. And I realise its a difficult decision for a newbie to make.
