Good work! However most people don't have space on their roof for 80 odd panelsHi, the attached pic shows that it is possible even in the depths of winter in Northern Ireland to get a "free" charge courtesy of the sun... the blue trace shows my Outlander making hay while the sun shines on my 20kWp solar array on the 20th January.
True enough... I only got my Outlander in November so this day was quite a novelty to me... PV specific outputs in Plymouth are much higher! Normally I charge overnight on the cheap(er) tariff of around 9p/kWh.WOW!
20kWp... you don't just have solar panels... you have a small power station!
Not the case for most solar panel owners though
Er, no. Hence my remark about being in Northern Ireland in my original post ;-) I noticed you're in Plymouth according to your profile. Hence my remark about PV outputs being much better where you are!Are you in Plymouth? Me too!
If you fancy a coffee sometime drop me a PM
That's exceptional output. Yesterday was an excellent sunny day here in Northern Ireland too but my 20 kWp system "only" managed 54.6 kWh. If I'd achieved your efficiency it would have been closer to 100kWh. My system is also south facing but lower pitch which works against me in the winter months, as does morning and evening shading which isn't an issue in the summer.I made 19.2 kwh yesterday with a peak production of 3.2wk. That's in Scotland in Feb!
(4kw system, 16 panels, South facing, shade free roof at 35 degrees - so optimum conditions!)
Yesterday was my best February day, and my system's been in for a year and a half. Peak summer output is about 120kWh/day. It would be interesting to see what difference the pitch makes in mid summer but my 15 degrees *should* work to my advantage then. If you get 6 times your rated kWp of 4kW ie. 24kWh in a day in June / July then you have a very good system indeed! Of course my summer output is largely wasted as I have less need for it so I probably should have optimised my system for winter output! My installer persuaded me otherwise. Today's output was a paltry 7.7kWh, a far cry from Finchley!It was my personal best production day. Not quite reachin peak performance but none the less I was delighted with it. Only installed system in Nov so not much to compare it to. Friend up the road only made 8kwh but he's got a lot of shading and another friend nearby with south facing but steeper pitch made 16kwh. I'm lucky that I have optimum conditions.
