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
