Q: One thing I remember from working on
temperature co-efficients before is the importance of paying attention to
whether the co-efficient is given as a percentage or in volts/degree. If it's
in voltage/degree, which I've seen on some spec sheets, than you've got one
less step to do. A: Good point! Usually it
is given in percent per degrees C and it can confuse some people if all of the
sudden the coefficient is given in volts or mV per degrees C. You can also convert
mV per degrees C to % per degrees C and vice versa. Typical 60 cell
module: 38Voc, Temp coef = -0.3%/C Math: -0.3%/C = -0.003/C More Math: -0.003/C x
38V = -0.114V/C And to go back Math: -0.114V/C divided by 38V = -0.003/C -0.003/C x 100% = -0.3%/C Thanks, Sean |
