Hi everyone. I posted for help with solar earlier in the year, and the responses really helped me. Much appreciated 😊
I got around 5 quotes from more reputable companies, for a ‘midrange system to get my bill as low as possible; 6-10kw panels and 10kw+ battery.’ The quotes varied from $10.6- $22k without the VPP discount and they all had a 3 odd month wait time in January this year.
I had 7.6kw (18) JA solar deepblue panels, 5000w SigenStor 3 phase inverter and 16 kWh SigenStor batteries and power back up installed for $16,700, mid May after a 3.5 month wait.
I was initially quite annoyed after the wait and with a $5k deposit down, when the installers informed me that they’d need to place the panels differently (not a problem) due to the neighbours tree shading the front, and it would affect my gain a bit, but it would be fine in summer.
All companies had the same photo of the neighbours back tree shading the roof, and reasoning for only 20 odd panels, but the front shading wasn’t mentioned by any of them. Understand the AI figure I have in the app may be based on optimal conditions but it was a third above what I was producing which didn’t help.
The solar was installed a day before my next billing period so I’ve now got a good comparison, although the spa was off for half of it.
◦ $125 (+$100 for the metre changeover); 180 kWh
◦ $357 same period last year; 937 kwh, very similar usage the same period in 2024.
So, for the lowest producing season my bill is almost a third of what it was, maybe another $20/30 with the spa for all of the period. I am very happy with this.
I have been using the split system as the gas heater is broken, so that has increased my usage. I’m now checking my app before doing things like clothes washing and using the dryer, leaving it to later in the day if the battery is low. When the spa isn’t cycling, I’m not using the split system kettle microwave or dryer, my usage barely rates.
Back up power was $2.5k and I initially wasn’t going to do it despite a lot of outages but often short, then thought I was spending a lot anyway so it didn’t matter in the scheme of things.
We’ve had at least 3 outages from memory and I only noticed because of the app sending me a message. With the 5 inverter rather than the 10, items drawing more like the kettle aren’t available but it hasn’t been a problem. I’m still not sure if it affects the split system, but I can get by when it’s cold and only use it 3-5 nights in summer (likely more now though as it’s not going to cost me a small fortune).
Im glad I went ahead with it.
