Hi Toby

I am quoting Marty’s message to others. Please give us more information.

What city are you in? Can you please give us an idea of your daily electricity usage in winter and summer (in kWh, you should find it on your electricity bill). Also, is everything electric, or do you have gas hot water, or heating?

Hi Ivan,
I am base in Perth, my monthly charges about $300 range, My home face South and will have plenty of roof space.
I have a pool at the back and gas water heater. I have 4 adults including myself.
Also informed them I am looking to get heat pumps for my hot water and another for my pool.
Don’t mind paying a bit more for better quality panels and inverter, and after monitoring my usage if the needs required will add storage batteries.
Was told due to restrictions from the grid I can only have up to 6 KW panels. Wanted to see is it practical to increase the power on the panels
Thank you

Morning Ivan,
I was at work so can’t check my usage.
From April to October the low of 1076 units to the high of 1766 units
December the lowest only 1 member in so 598 units
February to Aug this year the low of 893 to the high of 1730 units
Hope this is what you are asking for
Thank you

Hi @Toby.lau308

They both look like pretty good systems, and reasonably pricing. Have you checked that the installer has good reviews? Making sure the company is top quality is most important.

Other than that I guess it’s a tough decision about whether you spend ~$3k more on LG panels. They are really good panels, if it’s within your budget we highly recommend LG.

If your mainly focused on financial payback, I wouldn’t consider the Powerwall.

Hope that help!
Marty

Hi Marty,
Thank you for the feedback, The installer is from Bradford Energy.
Just received another quote from Evergen,
A 8.45kw system using Sunpower SPR-P19-325 panels 22 total
2 SMA inverter 5 and 2.5kw cost $13,713 before rebates (waiting for their reply on the rebate)
And to add powerwall 2 a 14 kw battery cost $26,353 before rebate
What are your thoughts for this quote?
Thank you
