Questions

You can raise a hand!

Problem 1: Focus only on Cost

“As I hurtled through space, one thought

kept crossing my mind - every part of this

rocket was supplied by the lowest

bidder.”

― John Glenn

Problem 2: Attention only to Modules

What Should Happen!

What Should Happen! What Actually Happens!

Problem 2: Attention only to Modules

Module

• Select More Efficient Modules and not

necessarily the one with more cells:Power of Module = Module Area x Efficiency

• Power Tolerance: Only +ve

• Temperature Degradation

• Bypass Diodes & Bus Bars

• PID Losses
