Some readings from the panel.
Hello,
These results are rounded and taken from two readings in Winter
afternoon sun. I used power resistors to get the results, the power
resistors are 10ohm 25w each. The sun was fairly regular. The most
regular we've had for over a week. The voltage readings were taken
from calculating the v drop from the resistor values and measuring the
current with a Fluke 111 meter. It's hard to say how much more this
panel will produce, but going from other panels around under the same
light these results are at about 80% full output as the sun was fairly
low in the sky.
5ohm 1000mA 5v 5w
10ohm 900mA 10v 8.1w
20ohm 650mA 13v 8.45w
30ohm 500mA 15v 7.5w
40ohm 380mA 15.2v 5.78w
50ohm 300mA 15v 4.5w
Kind Regards, Nicholas
