Good Morning Mart and all other solar lovers !!
At last I have got the name of my Sunny Boy, it is a SB4000TL-20, so fingers crossed this is the correct one for my panels etc. It seems that once we had a few days of good sunshine so higher production my system got the hang of it and is now producing quite satisfactorily, imo.
Hello Caz, I was only thinking about you yesterday, and wondering if you'd heard back yet.
The SB4000TL-20 does have dual MPPT, so is perfect for your split system. It's an inverter that I've noticed gets mentioned a lot on other forums (and it's smaller brother the SB3600 also dual). Both seem to be very well respected, from the comments I've read.
Glad production is picking up, I'm seeing similar with an ESE orientation, not so much fun 2 months either side of winter solstice!

Just noticed this (from last month) quoted above.
Not sure how you'd use calculus to do this ! I'd use trigonometry and specifically Sine, Cosine or tangent - all of which can be evaluated within msExcel
Hello Eric, funny the things you partly remember from school. 30 years on but I still remember 'The Cat Sat On An Orange And Had Hiccups', or
TCS
OAO
AHH
e.g. Tan = Opposite dived by Adjacent, how sad, can't believe that stuck!
so for my roof angle, which in feet is 7 high, by 12 long, by 13.89 hypotenuse, I can use
inverse Tangent 7/12, or
inv Cosine 12/13.89, or
inv Sine 7/13.89, or
let my wife use the spirit level app on her smartphone!

Even longer ago it was :
Some Of His Chums Are Having Trouble Over Algebra
Sine : Opp/Hyp
Cos : Adj/Hyp
Tan: Opp/Adj
And even earlier than that (so I'm told) it would have been :-
Some People Have Curly Brown Hair ( Till Painted Black)
where P was 'Perpendicular' & B was 'Base'

Ne interesting to see if the government attempts to pick out < 2011-12-12 & < 2012-03-03 commissioning dates any further news of legal developments?0 -
Have just submitted my 4th quarterly FIT reading. We've had our panels for a year so just wanted to check how they'd measured up to the predicted generation. The figure from http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php# was 2880 kWh for the year, double checked my spreadsheet for actual generation and the figure was.......
exactly 2880 kWh!!!0 -
Phew! Have finally read this thread from the beginning, just in time to get an installation date of next Tuesday. I can't wait. My neighbour got panels installed a couple of weeks ago and of course delights in telling me what he's generated that day. Soon I'll have no need to be jealous plus I'll be paying less for better panels

Beautiful day today , 13kWh generated (best since 1st September 2011), makes up for some of the day of 1kWh and 2kWh we've had lately
