If The HJ Solar panels perform well in low light conditions versus the Sanyo HITS (like the Suntech's do) it will be no surprise to me if the HJ Solars outperform the Sanyo HITS through this period of unsettled, cloudy, wet weather.

Well if somekind of conclusion based on 5mths of results is still NOT forthcoming, its time to give up..... unless there's other purpose to the thread ?

It needs at least several seasons to compare properly. If I publish results now there will follow a tedious barrage of 'aah buts' and 'what ifs' which I wish to avoid. The performance of different manufacturers' panels varies under differing meterological conditions, day lengths, and temperatures.

Why cant you publish interim results and state they are interim?
You could place a disclaimer beneath the results stating they aren't yet conclusive.

Generation cycle:- Shade till 9am & full shade @ 4pm SAP Target:- Yearly 2,367kwhr/pa, ASR - 1,027kwh/m2 Gen Figs vs SAP Figs:- Jan (73%), Feb (75%) March (125%) April (85%) May (103% so far) June ( xx ) Effect on Electric Bills vs last year:- -10% (Jan) -53% ( Feb) -45% (March) -60% (April) -49 (May) xx (June)

Maybe you can update your signature to tell us about June generation?

I was going to update ( within 2 days.. I might add ) but after careful consideration I think i'm going to wait a few seasons too as ppl could get the wrong end of stick with the information provided............

Re: PV Panel War: Sanyo v. Hengji. The ultimate side-by-side long-term, real-world t

It will take a year to give an accurate answer, since the characteristics of both panels may result in one out-performing the other under certain seasonal conditions. Day length, temperature, light intensity variations, and so on.

How is your real world side by side panel test progressing Sanyo v Hengji progressing?
1 year has passed since your initial posting Sanyo v Hengji: The Ultimate side by side long term real-world test.
Many forum members will be interested to hear your results. :ihih:

Hi, yes, I'm still here, but distracted by other projects this Spring. The panels are still there and producing what look like interesting results. But I'm having trouble getting a Serial port connection to a modern PC to download all the stored data for publication. Please be patient!
Cheers

different brand solar panels,inverters,labours costs make it different price.
0.9£/w will be the average level
