Title: July 2018 PV Generation
Post by: marshman on July 31, 2018, 07:28:11 PM
Capacity   Orientation   Slope   Lat        Total          kWh/kWpk    
3.15kWpk      157.0      11.0   50.9        571.7kWh       181.5

Best ever July, only 2.3kWh short of my best ever month. Follows on the heels of a cracking May (527.4kWh) and June (569.5kWh). First time I have had 3 consecutive months over 500kWh and 2 consecutive months over 180 kWh/kWpk  (Best month ever June 2017 @ 574kWh)

63.51 kWh.
Just under half my daily use. The balance has been drawn from the grid for laundry/micro/wshop machinery. Would have used more but only recently got the new (old) battery.next month may be better as I learn to manage the battery more efficiently.

A bit late to post but our 14 Yingli 230Wp with a  total output potential of 3.2 kWh oriented at 135 degrees (45 degrees East of due South) generated the following:-

Total generation -        478.7 kWh
Generation per kWh -    149.4
Worst day 29th              6.11 kWh
Best day  2nd           20.92 kWh

Thanks to that nice Mr Musk’s battery, we only imported 8.49 kWh for the month and indeed the total import for the last 3 months is 41.2 kWh
