Solar Panels

[kookaburra75]

Single phase. I had considered whether it would be worth changing to 3-phase, but it's a big cost, including some re-wiring and I wasn't sure I'd see a payback on capital. The idea of having far more solar capacity did intrigue me. I think I could have got to 30kW on my roof? But as it stands I just stuck with the maximum I could get which is 15kW connected to an inverter that can see the whole 15kW but only outputs at 10kW... though sometimes I see little overpower blips around 13kW for short periods of time.

The battery is a GoodWe Lynx F G2. I actually run two stacks of 12.8kWh each. They're pretty cool because you can start small and over time add new modules as you need it. There was a battery incentive program in QLD that helped, but only very marginally. It was mainly just an investment in technology, and it does help me when I get home to recharge my EV overnight completely, ready for the next day's journey, and not have to touch grid power - except for occasional blips every day (such as 0.43kWh today so far costing me $0.11).

That's interesting. We have an 8kW set up - originally through some ACT Govt subsidies for solar installation, which works well for MrsK and I, as she is retired and I work from home more days than not, so our peak use is during the day. I have been checking out battery options, but they don't stack up financially now. I plan to retire at the end of 2025 and replace my car with an EV, so the battery set up you have would make sense.

My issue with solar is that since installing the panels, pigeons have found a warm dry place to nest.

I had similar. Had to get up on the roof and install some PVC mesh under the edges of the panels and some "bird-deterrent" spikes in areas where the mesh would not work. The position of the panels on the upper-story roof and directly above the ground level patio roof made it a challenge to install the mesh along that edge. I am sure the neighbours were recording my antics hoping to make a fortune from a viral video if my scaffolding did not work as planned. Thankfully, neighbours did not profit from my efforts .

And at Easter this year I demolished that patio and hired a boom lift to paint the gutters/facia/eaves on that top level below the panels, and while up on the boom lift I was able to check and adjust the mesh as necessary.

Since those additions, pigeon roosting problem was solved.

so I've received 1 formal quote so far for my commerical property.
~7m warehouse ceiling

1. 18kW worth of (530-555W ea) Canada Solar panels
2a. Sungrow 15kW inverter SG15RT
2b. optional sungrow hybrid inverter, incase i want to add a battery next FY

Sungrow is coming out with a compact wall mount EV charger, later this year they said
so everything will be sungrow and everything can stay DC to keep electrical efficiency up (rather than converting DC to AC and back to DC etc)

2a. $17.3k ex GST
2b. $20.5k ex GST

waiting for 2 more quotes

thoughts on above please?

I thought batteries would be economical by now but still not yet.
We are now landlords as we sold the business last year.
That business now has pretty low electricity expense as they work sunlight hours mostly.
