Ultima solar PV hybrid 3.84kW predicted 5333kWhpa output

It is difficult to explain my position on this without sounding like a fanboy for Sanyo/Panasonic

From your data, what do you think you're seeing in your area's climate (which may be different to other parts of the country)?
What does the data - or gut feeling based on experiences - tell you the Sanyo's are doing?

I will actually publish all my findings on this site when I have them together.

I am comparing actual results with SAP calcs AND PV Sol estimates. As results come in, things do change a little. Sanyo are clearly performing very well though - although we don't have any Sanyo installs north of the Midlands. From the results I get, I think that the Sanyo panels give a good increase on yield on other systems - perhaps 5% - 10%. Although figures from Linuo are also impressive.

I have read on several threads of anecdotal evidence that Sanyo outperform the cheap Chinese in sunny conditions but underperform in dull conditions. Although I don’t have definitive evidence myself, I have monitored my 4kw Suntech system almost on a daily basis for a year with 2 other local Sanyo 4kw systems which are registered on PV output. I have noted that most of the time I seem to outperform the Sanyo's on a dull day by about 5%, but sadly the Sanyo's outperform me by 5% on a bright day and 10% on a really sunny day. Of course its the high yeild days which make the big difference so Sanyo should come out well on top.

The outperformance of Sanyo in bright / sunny conditions is not surprising as they use part thin film technology which works better at higher temperatures and as someone already said in this thread the tech spec of Sanyo’s have a a better temperature coefficient.

What I am surprised about though is that Sanyo’s seem to underperform in dull conditions. Again thin film is supposed to give better results (comparatively) by diffused light which suggests they should also be better in dull conditions. If they do underperform in dull conditions, my own theory is simply that their surface area is less and maybe it’s a bit like a large lens camera giving a brighter picture because it can capture more light than a small lens camera in dull conditions.

Back on topic.

Might the high annual figure combine the output of the PV with the output of the thermal system, 3500 from the PV and 1833 from the water heated? Seems to add up.

My sanyo array produced its best output in April this year, not so sure about the sanyo's anymore thought i would have produced more to date

My sunny beam says May on my other system

Where are you located?
Some parts of the country have sunny springs, while others have sunny autumns. Similarly, temperatures can show different seasonal patterns in different areas.
See the link to the met office interactive climate maps which I linked to in post #13.
