Hello all -- I am looking at putting a 1.5Kw system on the house in the southern Melbourne suburbs. The unit in question uses eight 190w Enertech Monocrystalline Solar PV panels and SMA Sunny boy invertor for grid connection.
After having read all comments in the forum I would like to know --
-- Is there substantial difference in generation of power with the panels facing due North or magnet north (kalindriel's comment)
-- Has any one heard of the panels and if so their performance
-- If any one in the Melbourne area has a 1.5Kw system what would be your average power generation. Not that I do not believe the sales person.
-- I see from "Russell Moore's' comments that the SMA sunny boy invertor is okay.
To much info on the Web that is mainly selling a product so I would appreciate any feed back from you good people.
Then on to checking all the different power company contracts in relation to solar power to the grid
What do you look for when shopping for solar?

MemberRegarding true north vs magnetic north, there is not much difference.
For average power generation, enter the location, system size and tilt into

and check out the results. My system is giving results consistent with PVWatts over the last 4 months since installation.Posted Tuesday 13 Jul 2010 @ 11:19:08 am from IP # -

MemberWe ordered a 3kw system from Todae back at the end of March. As soon as our deposit was paid they rang to advise the inverter we ordered - SunnyBoy 4000-TL - wouldn't be available until the next shipment end of April. We said we'd wait. In an email dated 29th March we were advised a SunnyBoy 4000-TL had been "locked away" for us but towards the end of April we were told it wouldn't be arriving. We were offered 2xSB1700 instead which we later declined due to concerns over eligibility for the GFIT with having 2 inverters.
Much to-ing and fro-ing of emails later we accepted an SB3800 instead of the 4000-TL and were given an install date of 4th June. The solar panels (18 x SunTech) went up on that date but when the inverter was connected on the 24th of June we were advised only half the panels (9 out of 18) were working. Installers have been out to replace the panels but as of today – 15th July – we still only have 9 panels working and no idea if or when the system will be connected to the grid.
Ultimately our advice would be to confirm with your solar provider that they do have your preferred equipment in stock before placing an order. Good luck!
