I passed 6MWh this past weekend. I've had my system online since St Patrick's day and needless to say, I'm very pleased. I need to go buy a truckload of Christmas lights!
That's impressive! I have found with our last array we got about the array size in kw a year, 1000w array should make about 1000 kw/h a year. Our current system has only been up and running 5 months now, time will tell.
3kw solar PV, 8 L16's, xw 5548, Honda eu2000i, iota DLS-54-13, Leaf EV, 4 ton horizontal geothermal, grid tied - Green Bay, WI
Forgive my newness.....as I'm just about to bring my system online....but are you saying a 1,000 watt array only produced 100Kw/hrs in a year ? 100/365 = .28Kw/hrs per day...280watt/hrs/day.....surely that can't be right..... or I'm not understanding something.
Autoxsteve is doing 1,000kw/hrs a month with 4,100 watts of panels, or about 250kw/hrs per month per 1,000watts/panels. Of course, he has a great sun resource there in Southern Cal.....but I was hoping for 350-400kw/hrs a month (yearly average) out of the 2,100 watts of panels I'm about to bring online here in East TN. I'd be VERY happy if mine did 500kw/hrs a month yearly average !
Steve: Are your panels fixed mounted ? Mine are mounted on two poles with single axis tracking. I was given to understand that SA tracking would increase my gain about 25%, so I 'might' just come close to your figure if yours are fixed. Given the amount of pain I went to in building these trackers, I sure hope this is the case.....
I was given to understand that SA tracking would increase my gain about 25%,
PV Watts suggests that +25% for SA tracker vs. fixed array looks about right for your neck of the woods. Full benefit will require clear "view" from East to West (no trees, buildings, etc.)
WOOPS, yes that should be 1000kw/hr. (I will fix that)
In the past 16 weeks (since I had 960w up and running) we have generated 298 kw or about 21 kw a week although the numbers have been falling since the install because of less sun each day and our lovely weather. Even if we average 20 kw a week that will be just over 1000 kw/hr a year. In the solar map we are at about 3.5 hours a day over the year.
