so this is what we ended up going with for our house... obviously not going to give us a $0 power bill, but it'll make a dent in it, no?

i don't really know what any of this means, so copy and paste from our quote:
"19 panels, 4.94kW Winaico WST260W and a Fronius Primo 5kW Inverter with energy meter"

Ash, basically it says you are getting 19 x 260w panels and a 5kw inverter.

I have 1.5kw and it gives me $90-$150 back depending on time of year. I am also on .50c feed in so you would use your system differently to me to get the most gains.
I just don't know if people like me. I know when they don't like me 'cause they'll say things like, 'Yeah, that's him, officer.'

Ash - We have 24x260W panels (same Winalco ones) and the same Fronius inverter and on the tiny 6cent buy back so we try to use power during the day. The panels are split between East (8) and West (16). Because of the large trees next door (North) the shade from the trees kills us in winter, but in summer we are pretty much generating enough to keep our cost down to the daily connection fee.

In terms of savings, first bill this year was a 50% decrease on last year, and the second bill 35% decrease.

We're getting 14 x 260w Winaico panels aswell (facing north west) in addition to the 16 x 190w Trina panels we currently have which are north east.

With the current Trina setup, we offset around $240-300/quarter depending on the time of year. The new panels should add a lot more to that now we'll be exporting even more power during the day at the $0.50c tariff.

The guys "estimate" (I don't know how accurate it is...) said the payback for the upgrade would be under 3yrs.

I am no expert but just make sure that the change to the system you have doesn't affect the $0.50c rebate as they are attempting to phase it out as quickly as they can.

My system is 12kw worth of panels and is awesome but it is diminishing returns the more you put on if you don't get the rebate - currently if you can get the rebate then every extra panel is gold

It won't affect Noel as he already has a 6kw inverter, as long as he doesn't upgrade that he can add all the panels he wants.

Yep all good on the FIT front. The FIT is based on the inverter that was approved, and we deliberately locked in the 6kw inverter when we did for this reason. If my inverter ever dies, I can replace it with the same capacity, or less and not lose the FIT. I can't upgrade otherwise I'll get bounced. What I have now is just like if I had 6kw of panels, and half of them were dead.

Effectively all I'm doing now is just expanding to my allowed capacity.

So today was the first day of (more or less) full sun since the system was installed.  I'm pretty happy with the results...

Almost 28kWh produced today...

And today has not only cost us nothing, but made us money.  Light blue is power made.  Orange is power used at the same time.  Dark blue is net exported.

There's only 1 issue I'm still trying to sort out which I'm waiting on Enphase support for, but apart from that...I'm really happy with the purchase.  Tomorrow or Tuesday I'm going to get up on the roof and give the old solar panels a clean.  I was up there before the rain and they were pretty dirty.  I remember last time I had them cleaned I gained 10% from those panels.

So now that I'm making fat stacks soaking up the suns energy, its reignited my interest in PVOutput etc.

Since getting the additional panels put in I've been monitoring my power production, and I've been peaking at around 5100-5300 watts of power when the sample was recorded.   In the 2 weeks since the panels were put in, my highest peak ever was 5400 watts.

Now - bear in mind I have a 6.68kw system, so those numbers might sound low.... but because of the way the panels are... I don't make anywhere near 6600 watts, but what I do make is 5000w+  for a long time as the sun travels across the roof.  So...think of it like I have a 5.5kw system, my panels face directly north, and midday for me lasts 3hrs.   (if you know what I mean...)

Anyway - so yesterday I got up on the roof and cleaned my older panels.  I remember last time I had them cleaned I gained 10%.  I figured this time I'd do it myself.  I just got up there with a microfiber mop, a bucket of clean water and a long extension handle.

In the 2yrs since they were last cleaned, they were covered in black dust.   Like at first they looked clean, but it wasn't until I wiped them with the mop that you saw how much dirt came off.

Fast forward 30min and I get back down to check pvoutput.

I was instantly making 5800 watts of power.  So we're talking about a 400-700 watt gain on peak power compared to any other day in the last 2 weeks.  And this was yesterday...with some clouds.    That number will only get better as we move into the summer months.

Powerwall 2.0

Cheaper, higher capacity, and has the inverter built in so there's no hidden costs..

30kwh of battery backup for $24k....that's looking way cheaper now!

Has anyone heard of Solarkraft? I have a mate who has received a proposal from them and they seem to partner or sell to Diamond Energy at 20c/kwh and guarantee pay back etc

My concerns are:
1 - If sounds too good it usually is
2 - Its a heavy sales pitch which usually refers to point 1
3 - If they go out of business he would likely revert to 6c and the payoff wouldn't be guaranteed

They look to be *very new*. Most reviews of them are within the last 4 months and are all 5 star etc. Also not a single mention of them on Whirlpool yet (which is odd).

I would go with your gut, and point 1 of what you wrote.
