<DIV><FONT face=Arial size=2><SPAN class=820142107-20052010>I would like to
estimate the solar radiation on a tilted surface with Type
16c by choosing Mode 2 (Total radiation surface on a horizontal
surface, ambient temperature and relative humidity datas are known). These
threes datas were measured with a step time of 10 minutes from November until
Februar. I want to calculate the effective radiation on a northern and a
southern orientation, in order to estimate the effective solar gains with a step
time of 10 minutes.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=820142107-20052010>I can't obtain
correct results because I think I don't understand the inputs 4 and 5 of Type
16c. What does "Time of last data read" and "Time of next data read"
mean?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=820142107-20052010>Is it possible to
use this type with a timestep of 10 minutes but with measures on only 4 months
(not a complete year)?</SPAN></FONT></DIV>

and your answer!</SPAN></FONT></DIV>
