690 Part VI is a shorter Part of Article 690 and the end of 690 was dramatically reduced and rearranged in the 2023 version of the NEC.

 

Here are some of the topics covered:

 

690.56 Identification of Power Sources

690.59 Connection to Other Sources

690.72 Self-Regulated PV Charge Control (neat silicon science here)

 

This podcast is mostly a reading from the 3rd Edition of PV and the NEC by Sean White and Bill Brooks. You can get this book here:

Terence Parker gets surprised by Johnny Weiss, Solar PV History!

This podcast is full of solar history, so we give a shout out to the solar historians 100 and 1000 years from now!! Hey people who have not been born yet! Check us out!!

Terence and Johnny have been doing solar PV since the 1980s and have known each other since the early days.

Terence tells the story how he was on a small airplane in the South Pacific in the 80s wearing a solar shirt and Ward Bower, the inventor of the grid-tied inverter, tapped him on the shoulder, which started his solar career full steam. Before that he was a marine biologist trying to figure out how to get electricity on a 12 acre island, so he could study oysters. The moral of this story is to always wear a solar T-shirt.

Johnny Weiss is famous for starting Solar Energy International (SEI) in 1991 and has been working with PV modules since the mid 1980s.

The story of how we decided to do this podcast goes... Johnny invited me to see the SEI campus a few weeks ago and I asked him to be on the podcast. I told him how Terence Parker was going to be on it, and he had great things to say about Terence, so we decided to make Johnny the surprise guest. Johnny was very helpful at helping me interview Terence, so he is probably going to help me interview more historical figures.

Here are some of the names we dropped and things we talked about:

Arco Solar

MREA

SEI

Bob Ramlow

Solis

Solar Bridge

Ken Olsen

Home Power

Richard Perez

Borneo

Sri Lanka

Brazil

World Bank

Sandia

Unisolar

Out of the jungle

Ward Bower

Walked the PCH

Diving for oysters
