Panels: 20 X 330 Watt Trina 330 haif cells Mono Panels.  
Inverter: 1 x Goodwee 5KW 1 phase wifi Inverter,  
Installed on a TIN roof, ACT, Single Phase  
All done for $3950.

We are 2 Adults and 2 Kids Family paying electricity bill around $425 a quarter.  
Couldnt decide if we would have a ROI. Need some solid backing to get permission from the lady of the house.

Is this deal fair, can you help me?

Thanks

Hi @phoneicx

You would certainly have some sort of ROI, and I’d imagine it would be quite good. It’s a reasonably straight forward calc actually. How much electricity do you use (in kWh, you’ll find it on your bill) and what % do you use during daylight hours approx. And how much do you pay per kWh (also on the bill).

I would have thought at that price your payback would be 3-5 years, and then it’s all cream. However, we generally recommend investing a bit more, at least in your inverter, which may put your payback period out further, but would also improve your chances in having a healthy system for longer (and improving your ROI in the long run).

Cheers  
Marty

> Hi all. Brand new to this forum and solar thing so if seemingly very uninformed it’s because I am! Just got the above quote via a door to doorer which has initiated me actually doing some form of research. SE Qld site, no shade problems at all with a north facing roof that can fit 24 panels. They also offered ABB inverter instead for $10K. Am thinking I’m better off looking for better inverter but really no idea. Any guidance would be muchly appreciated. Thanks in advance…
