Our annual consumption is around 14-15kWh / year (30-35/day Summer, 45-55/day winter) +/- a bit spring and autumn.

 

Thanks for the comments on Sigen, 

 

I was pleasantly surprised by the price, was expecting north of $25k. I'm prepared to spend/invest as much as necessary to get a good system without being stupid about it, theres a point of diminishing returns somewhere I'm sure.

 

 

 

 

If you're able, definitely oversize the inverter to 8 or even 10kw so you're covered the whole time the sun is up. Even lets you charge or export back for credits. Get a bigger inverter and slam as much panels as you can.

 

Our consumption is not so typical as we charge 2 EVs & battery garden tools, diverter controlled HWC, pumped house water and on the minus side heating is log fire. That said our consumption for the last 12 months was 11,500 kWh (which included builders power tools for a major renovation). Our total generating capacity here is projected at somewhere north of 18,000 kWh. (Total capacity went online in June 2025).

 

Also the array we have on our house roof is 5 kW which is solely exported and generates ~7,500 kWh/year. We saw very similar generation from the 5 kW set-up we had at our previous property, and in both cases they were north facing with near optimal tilt and minimal shading.

 

You have good generation. I believe last year we used up around 16k - 17k kW.

Our system is 11.44kw with a 10kw inverter, wondering how good ours would be in terms of generation. Been cloudy as the past few days though.
