Solar Electric for the home

Quarks,
Good to see you have got your pV system installed.
re your orientation......the "Clean Energy Council of Aust." have a very handy PV design guide which gives tables of efficiencies for different panel inclinations and orientations around the country. It is quite difficult to find on their web site but I have a pdf copy so if you are interested pm me and I will email it to you.
I have just had a 10kW system installed but still waiting for meters and inspection so it is not generating yet. However, the system supplier told me originally that it would not be worth installing the 55 panels on a tilt frame to get the optimum 30 deg (roof is flat) but by referring to the tables I could see that I would get an extra 10% power with the frames so they will pay for themselves in less than 2 yrs.
regards.

looks like you might need to trim some trees bundalene the panels at the end are shaded along with the solar hot water

Bundaliene,
What time of day is that photo taken? Did you know that when a part of even one panel is shaded it cuts output dramatically from the whole string? It is NOT proportional! Like 10% shade equals 10% loss!
I found this out the hard way and got the installers back to move my panels. They grumbled but admitted that it was their fault.
Cheers.
BW

Hey Isuzurover,
just to let you know, the inverter needs 240vs from the grid to operate, not just from yr solar array. A stand alone system is the only option

Just read an advert from Selectronic (Selectronic Australia Pty Ltd) touting their SP PRO inverters, designed for just that job. "Battery based grid feed inverters" Probably cost many many thousands to set up but worth the one-upmanship in a dark street.

Is that a rain gauge? Oregon Scientific perhaps?

Well very interesting post

I have just got 11 grand back from tax and 5 grand surprise bonus so I am going for the full kit of solar for the house

Just about to do the deal

I've had my panels on the roof for a while now. My meter box needs updating before I can get the panels connected. I'm short on funds so it will have to wait. The question is can I wire up a power point to the inverter and use the power while the sun shines. not sure what I'd wire it to, maybe the hot water and heat it in the middle of the day.

The grid-connect inverter will not produce any power until it is connected to a working mains supply. So unless it is wired to the live mains you will get nothing out of it. When it is you can withdraw its power from any power outlet in the house. I suggest you let the electrician do it. The DC voltage from a panel set is high enough to kill (150 + volts) so don't try to wire it to a regular inverter.

when you get a few quotes, go to places like jacar etc and see how much thier pannels etc cost
