[RE-wrenches] Temperature coefficient versus Power

[Dave Angelini Offgrid Solar]

10+ years ago I thought that Sunpower Solar wrote the best info. Their 
module technology was superior and the classic 327 module output was 
amazing in high temperature and also in cloudy skies. They were the 
first to have really good warranty for both workmanship and output over 
time.

I have little to say about the current crop of modules.
