So now I have a solar PV system how do I make the most of it???

Wow Don, is that really 1.73kW (7.56 Amp) being generated by your system just after 9am! - although I see the Amps was at 7am according to the clock. I think I'm lucky to be getting 600W with the slightly clouded sky at 10:30 here in Bedfordshire (South) You really are in a favourable location. Must think about moving East a little.
7.56Amp at 7:02am - that means 1.7kW before the sun rises - are you sure?
edit Sorry, just realised the display had just turned to date format 7 Feb '12

Scraping the bottom of the barrel now guys!
Two years of running an anti PV campaign on MSE and the best you can come up with is that decent winter generation isn't possible? Scroll back on the thread and take a look at some of Jan's figures.
I'm almost as jealous as you.
Don't think Don needs a cuddle C, he's got your FITs to keep him warm!
Mart.
Always like to pop in now and again to see which respected and intelligent poster Don is currently insulting and arguing with.
Anyhow, before this 'no winter generation' gets even further out of hand, could you post where anyone has actually said that? The only difference I can see between the power produced at midday summer and winter from radiation due to the lower sun's angle at midday (in the uk, possibly excluding Essex) is the thickness of atmosphere the radiation has to penetrate. Point panels at the sun and that will be the major difference (the lower ambient will help in winter which will partly compensate).
Anyhow, I think I've got Don sussed - always picking a fight, has had no education, not from Essex but lives there, always being moved on (to the sunniest bit of the UK everyday!), not really sure where he lives - you didn't until recently live at Dale Farm did you Don?0 -

My roof is not as steeply sloped as Don's, so can't expect to get as much proportionally. What gets me is that for Don to get 18.7kWh yesterday there must have been over 3kW generated constantly for 6 hours. My system peaks around 2kW for only an hour or so when the sun is in the south and then drops back as the angle decreases.

I didn't get 18.7 kWh yesterday, I got 18.7 kWh on 2nd Feb 2012. as per my signature.
I got 13.5 kWh yesterday, as per my post 1377
stop making **** up,
thanks.......0 -

If you could measure or accurately estimate the angle between your panels and the sun at midday, you could easily calculate the max power you could get that day (by pointing the panels normal to the sun) by dividng the actual power by sin(suns angle to panel). Be interesting to see if that is near kWp.
Never really understood why someone hasn't devised a cheap motor to always align the panel framing to the sun at midday, given the level of fits which I guess could make it cost effective.0 -

3.22kWp - 50 degrees pitch - South Norfolk0

Damn Raider - that's some mighty big generation.
Looks like you and Don have stolen all my sun again. Was supposed to get a good day, but only 50 to 200watts all morning.
Need steeper panels.
M.Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.
