Net-metering, bypass diodes, solar & storage and NEC Article 480 vs. Article 706 Q&As

In this question we have the following questions and answers:
 
1. Net metering: Why it is different in different places whether or not you can and should feed energy back to the grid when you have an excess.
 
2. How bypass diodes work and also with half-cell PV modules.
 
3. Why solar goes so well with energy storage systems (ESS).
 
4. National Electrical Code (NEC) articles 480 Storage Batteries vs. 706 Energy Storage Systems and why you should use 706
