<p><span style='color:black'>We are responding to a bid where the electrical
engineer has designed a system with different sized Uni-solar laminates in
some series strings paralelled with consistant full size strings.
(this was done to work around skylights etc).<o:p></o:p></span></p>
<p><span style='color:black'> <o:p></o:p></span></p>
<p><span style='color:black'>We suggested that this was a poor design and will
lead to "least common denomenator" performance, exacerbated by MPPT
confusion. The EE responded that "the bypass diodes allow for this".<o:p></o:p></span></p>
