Thursday March 18 through Sunday March 21 Friday and Saturday were near perfect sun days. Sunday had some morning clouds. Successive new records at hilltop. Kwh sales as reported by electric provider, Bluebonnet Electric Coop on the three meters that earn $.06/kwh.
Thur-Sunday :
New "hilltop" under construction : 71.1, 84.93, 92.16, 108.99 as I was adding panels. Today will be a disappointment due to cloudiness.
Across road: 327.74, 319.87, 319.74, 319.91
House: 219.2, 217.86, 203.2, 202.69
Totals: 618, 623, 615, 632
$37 - $38 per day for four days. "Overhead" connection fee is about $.75/meter/day. So, net about $35/day.
Our peak production is in the period July-September. Probably. I hope to be averaging about $50/day by then.
For a tracking system, May and June are the peak months for solar energy production, as the sun is high and the length of the day is long, which means your panels will get more sun, and therefore produce more energy. My fixed array that is monitored by Enphase Enlighten shows two definite peaks in production. One is in May, and the other is in Sept. The Lifetime Energy Graph on Enlighten now covers the last six years. Solar Panels like cold and clear weather. In mid-summer, it is really hot, so the panel output drops. Also, the fixed array is an average, once again seeing two peaks as the sun changes position. It might be hard to analyze a whole system because of the constant addition of more and more solar panels. Enlighten data on your first 4 panels might be enlightening.
ReplyDeleteI haven't looked at Enphase monitoring in quite a while. Mostly, I don't know locations of inverters based on serial numbers. I guess, I could go out and record serial numbers of those four very old inverters. Then, search out the data on them.
