Grounding, Microhydro Hybrid Systems, Batteries & Mono vs. Polycrystalline Silicon Solar Cells

In this podcast we answer 2 questions:

1) Grounding is important and can be confusing with many different theories of how and why it should be done. Here we are going to talk about the basics, including the neutral (grounded conductor), the equipment grounding conductor (EGC) and the grounding electrode conductor (GEC). We will even make a mention of SWER (single wire earth return), which means using 1 wire for transmission and using the Earth as a conductor! Here is a link about that last part, so you don’t think I am making it up:

2) Batteries were once always included with PV systems and not as the grid has more intermittent renewables, batteries are making a comeback. We will discuss energy storage, off grid PV systems in Haines Alaska’s Mud Bay and microhydro for generating electricity.

3) Monocrystalline PV has taken over the number 1 spot from polycrystalline silicon solar cells in the last few years. We will discuss the differences of how these solar cells are made and how they look.
