Hi all, I have a 3.84kw sanyo system sitting on my roof and when comparing it to other users admitted outputs on this site it seemed to be running quite well. However when browsing through PVoutput where I also input my figures for anyone to compare I have come across a system which is slightly larger( +.112kw) but appears to be blowing my output figures apart.
The system in question uses samsung LPC247m panels which have a stated efficiency of about 15.3% and a SB 4000tl inverter which I accept may also be slightly more efficient than my SB3800.
It also faces south while I face south/south east and at this time of year I loose the last 1/2 hr of light to shade from houses and trees on a bank several hundred metres away
On the total outputs my system has produced nearly 497kwh in 88 days but this other system which is maybe 25miles away has produced 637kwh in 91 days and today which was a overcast day with showers I have managed 1.66kwh against 4.8kwh
It is generally accepted that the 240w sanyo panels are the most efficient on the market but having parted with my hard earned cash it is slightly annoying to see a system producing nearly 20% more.
Thoughts anyone.
