Thread: Solar panel positioning

Trying to obtain anything other than bulk yield varies state to state as it depends on your feed in tariff, if you receive wholesale price, 8ish cents/kwhr it makes sense to match your usage, but if you receive a good tariff, best to aim for bulk yield, concentrate on peak sun hours. All varies with location/shading/mounting/cost

Cheers. Unfortunately I missed the boat on 49c/kWh in WA. It is now down to 7c/kWh...

Best to match usage then, might have to lash on a dual mppt inverter!

Been looking into stand alone viability, a dude who has been subcontracting for me is hoping to play with a setup, just need to get the return of investment down to something reasonable

Finished a stand alone today for Ross, 14 panels, 2 in series, 7 in parallel, 3kw Latronics 24v inverter, 60a reg, with 8x 6v 535 a/h batteries, 1070A/h. (4 in series then parallel) Seems to work ok so far, its got me thinking to now. Alot more wiring though.
In Dollar if ya want a looksy

The inspector came out Saturday morning & turned everything on, 19KW generated so far.
Then our "electricity provider" rang today & this is the deal- no names, no pack drill

We currently pay 22.671 cents/kw flat rate 24/7 - less 12% due to contract.
plus 88.385 cents service charge a day.

For Solar connection they want...
$44.21 to configure the meter plus a $49.14 fee if access is difficult- but otherwise refunded.

Then the rates go to
Peak 3pm to 11pm 35.5 cents/kw
Shoulder 7am to 3pm 25.27 cents/kw ( not certain of the decimals but thats what I wrote)
Off peak "all other times" - ie 11pm to 7am 11.73 cents/ kw

96.91 cents per day service fee

BUT - I get to keep my "advantage 12" discount.

Now this was said to me by an Indian guy with associated accent- no make that prattled & I said whoa up, I need to write this down ( much to his annoyance) and he immediately pressed me for a commitment & put on the surprised reaction at me when I said I needed to think about it. That got me going & I said we would not be having this discussion if they had these figures on thier website, when pressed he said that they are on the Origin site ( which is another company)

I'm not regretting going Solar, most, probably 80% will go to internal use anyway as we use 25kw/day & I now have told the missus to try to do the ironing, washing, vacuuming etc during the day, & one at a time if not sunny
But I've asked for a copy of our agreement to be emailed

your not with Lumo are you? Whatever the case i have whether it bew solar, basic truck appoointments, Lumo are the most useless company i've ever dealt with. I did a job with them that took 6 months for a basic truck appointment, this normally takes 3-4 weeks.

Not with Lumo, AGL.

Not much better, still waiting after 4 weeks on a truck appointment for a meter panel upgrade

I was talking with a dude in nsw, I'm doing a 7kw install for, they do nation wide solar, he said Vic retailers are the worst nation wide, by a very large margin

7 kw in Yinnar? They rang me to if it is, said ok send me the info, never got it. no biggy
