Thoughts on a 10.3kw solar battery from shinehub after rebates. Total out of pocket $3930 in Victoria
10.3kw Solar Battery for under 4k
Comments
On a good day you should be producing 21kwH per day. If you have a 8kw battery after charging you'll still get 10kwh to use?
This page says 1kw system in Melbourne produces 3kwh a day
Battery pay back is too long. The retailers are hoping people will jump on so they can access it. Nothing like someone putting the upfront cost and they make a cut (bit like Uber).
Is there an income cap on the battery rebates? Every time I've looked into rebates the household income cap is ridiculously low.
Interested to know this as well, as batteries have been outrageous prices when I looked into it.
180k combined. Unfortunately I qualify
These subsidies are ridiculous. $180k is way below the household income for two professionals.
Some would suggest that $180k you should be able to afford those things, not relying on govt subsidies.
Heck, I could afford it on significantly less than that - but I don’t eat smashes avo on toast or buy lattes.
A Tesla battery is about 14Kwh and costs about $14k installed so this doesn't sound like a bad price?
Those solar numbers sound low quoted above, our solar system is 6.93Kw 14 panels facing north and 7 west. In summer we've broken 50Kw on a handful of days, most days at the moment are 40+. A 10Kw battery would mean we'd draw nothing from the grid unless we need to use the AC overnight.
In winter we were generating 14-18Kw on average, so we'd still get enough to cover a lot of our overnight usage as well.
The two bills we have had since installing solar were $20 and $160, so it would still be a significant payback period at $4k if we got our bills down to zero. I'd anticipate never owing them money by the end of a bill period though, so might be better than I think.
Based in Melbourne, we have a 6 kW system and for the 3 months ended 15 Jan we received a feed-in credit for 395 kW. At a value of 20c per kW, storing that surplus in a battery would save us just $80 for the 3 months - def. not worth investing in a battery.
I currently get 10c feedin and last qtr fed 800kw back so only $80 credit. Keeping the power would save me about 2k a year in usage so payback would roughly be two years. Even if only half what I calculate should be paid off in 4 years.
What tarrifs are you on?
Assuming complete charge/discharge of 10.3kwh each day, best case 2k saving would mean you pay 53c/kWh during night time/off-peak.
What subsidies?
Can you draw power out of the grid through a controlled load metered tarrif?
I was considering a battery too for my setup and I'm in Melbourne.
I was talked out of it by the solar installer.
He said it would be good for Cairns or some constantly sunny place like that, but Victoria is only sunny - sunny for summer and even then, the amount stored is only a trickle each of those days (after usage) such that the battery is likely to be empty for the rest of the year.
Mine is only a 7.6kw? Something like that, can't remember right now but definitely not 10kw
