<DIV> </DIV>
<DIV>I am using type 536 (linear parabolic concentrator) and I have a simple question: </DIV>
<DIV> </DIV>
<DIV>How do I calculate the total surface of solar field? Is it simply: </DIV>
<DIV> </DIV>
<DIV>"Number of collectors in series"x"Number of collectors in parallel"x"Aperture area"? </DIV>
<DIV> </DIV>
<DIV>I ask because it always seems like I need an awfully large surface if this is the equation I need.</DIV>
<DIV> </DIV>
<DIV>Please advise. </DIV>
<DIV> </DIV>
<DIV>Best regards,</DIV>
<DIV> </DIV>
