Solar panel positioning

So why is that the case electrically?

I suppose I will wait until the inverter dies, then switch to a dual mppt and add more panels on the NE facing roof.

Loosely, when you have two different strings(rows of panels on series) that get sun at different times, the one with sun wants to turn the other into a heater, they need to be matched both electrically and position, azimuth and inclination, unless on a dual mppt inverter

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 :angel:

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:D
But I've asked for a copy of our agreement to be emailed :twisted:

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:)

Their rates were average, after amendments it'll be a 2.5k profit for a big day after overheads
