OK. Need to get a quote to a customer tonight but hit a snag. The roof has a 15 degree pitch but table H2 doesn't have a radiation figure for anything less than 30 degrees (see below). What figure should I use? What do you use?
Table H2 : Annual solar radiation, kWh/m²
Tilt of Orientation of collector
collector South SE/SW E/W NE/NW North
Horizontal 933
30° 1042 997 886 762 709
45° 1023 968 829 666 621
60° 960 900 753 580 485
Vertical 724 684 565 427 360
Thanks in advance.
Austin Gregg.
