Bidirectional EVs with Alex Cattelan, COO Fermata Energy and UL 9741 EV Power Export Equipment

In this podcast, we learn how UL issues first certification to UL 9741 (and UL 1741 SA) for an AI-Driven Vehicle-to-Grid Compliant EV Charger to Fermata Energy.

 

https://www.ul.com/news/ul-solutions-issues-first-certification-ul-9741-and-ul-1741-sa-ai-driven-vehicle-grid

 

Alex Cattelan has been working on EVs for 2 decades and has experience engineering many famous electric and hybrid vehicles, including the Chevy Volt for GM. She also has extensive experience working for Polaris, Johnson Controls and many others.

 

At the end we decide to go to Burning Man together on a bidirectional electric bus and she is going to teach me how to do wheelies on an electric motorcycle. Nothing can compete with the torque of electric motors, much more than those old fashioned explosion driven motors.

 

Here are some of the topics we cover:

UL 9741 EVPE (Electric Vehicle Power Export Equipment)

John Deere EVs

AI for EVPE

Software engineering

Drive trains

Electric vehicles  

Nissan Leaf

Chevy Volt

Garret Little, NABCEP PVIP - Garret just passed his NABCEP exam!!! Celebrate!!!

One week before recording this podcast, Garret Little passed his NABCEP PVIP exam, scoring impressively after nine years since his first attempt. In this episode, we discuss his exam experience, memory techniques, and the differences between the Ecotech and HeatSpring prep classes. Garret shares insights on what’s essential for passing exams and highlights the NABCEP courses available.

Garret also brings his international experience, having installed PV systems in Nepal and Colombia.

Topics Covered:

• Exam prep and strategies
• NABCEP certifications (PVIP, ESIP, PVA, and more)
• Online vs. in-person testing
• Memory techniques and learning methods
• Insights from Garret’s exam journey

Garret expresses his gratitude to Sean for the impactful HeatSpring courses that helped boost his confidence and knowledge:

This course really covered everything I experienced on the exam and in all honesty, to me it seemed it presented quite a bit more information and material than the NABCEP covered, at least from my experience . For example, I don't think I had one string sizing question, conduit fill, or even conductor sizing with derates (if my memory serves me right). It was not nearly as much calculations as I had anticipated, aside from interconnection calcs, which were all fairly similar.

With that being said, I feel tremendously more knowledgeable than I was even just a few months ago prior to taking this course and I am so thankful for that. Thank you again so much for working with Heatspring on these courses to provide such  thorough, entertaining, and educational content. It feels so incredibly good to not only have passed the exam, but to feel that much more educated.

derek the solarboi, the TikTok and YouTube Sensation!!

I came across a really cool YouTube video, rivaling Mr. Beast, but for solar, which was a purple bearded solarboi going off on Rapid Shutdown UL 3741 PV arrays, I immediately contacted him and a week later, here we are recording this podcast. This guy is entertaining and we are lucky to have him in the industry. This industry needs to be fun!!

 

derek the solarboi has 3 NABCEP Certifications

 

PVIP (PV Installation Professional)
PVCMS (PV Commissioning and Maintenance Specialist)
PVSI (PV System Inspector)

Altogether that looks like:

 

derek the solarboi, NABCEP PVIP, PVCMS & PVSI

 

That is a total of 18 letters after his name, making him super special!

 

We talk about some controversial subjects, including Rapid Shutdown and I always try to be bifacial and take both sides for educational purposes, but encourage my guests to have strong opinions. If you have a strong opinion, let’s get you on the show!

 

Here are some of the topics we covered:

Other rad solar creators, like Solar Goat (https://linktr.ee/solargoat) and The Solar Slayer (https://thesolarslayer.com/)

Tyler Hortin of Lion Energy-A Lithium-Ion Energy Storage Company

Great conversation with Tyler Hortin! His company does everything from Wh to GWh and focuses on prismatic cells that are almost 1kWh! This makes for less cells and less connections that can go wrong. The technology here is Lithium-Iron Phosphate (LFP) and we will talk about the supply chain and implications of the Inflation Reduction Act (IRA). They are affiliated with American Battery Factory, so we talk a little bit about manufacturing in the USA towards the end.

 

Key Words:

Lithium Iron Phosphate
Prismatic Battery Cell
Battery Manufacturing in the USA
How he get the Iron
LPF
Lithium (L)
Iron (FE)
Phosphorus (P)
Great Salt Lake
Battery management system (BMS)

Solar Energy and Policy Entrepreneurship: a Discussion with Erica Goldman, Alice Wu, and Zoë Brouns of the Federation of American Scientists

In this episode we are triple fortunate to have three of the smartest individuals in a discussion on science and policy from the Federation of American Scientists (fas.org), a nonpartisan think tank connecting scientific research with policy making to address today’s most urgent needs. Transition to renewable energy is urgent! We talk about how we can transition to solar fast, and how science and policy need to work together to get the job done, and how individuals can get involved.

 

Guests:

Erica Goldman, on systems thinking and solar
Alice Wu, on tipping points
Zoë Brouns, on the workforce needed to meet the moment

 

Topics discussed:

• American Climate Corps, which is an IRA program intended to mobilize the green workforce on par with the FDR programs (see Civilian Conservation Corps), modeled similarly to the successful AmeriCorps.
• DOE (US Department of Energy)
  

  • Virtual Power Plant Commercial Liftoff Report
  • DOE Commercial Liftoff homepage
  • Clean Energy Talent Workforce report
• FAS History
• Manhattan Project Los Alamos
• Clean Energy and Climate Policy
• Science, Policy and Policy Entrepreneurship
  

  • SUBMIT YOUR IDEAS!
• Congress
• White House
  

  • Inflation Reduction Act (IRA) 2022
  • Bipartisan Infrastructure Law (BIL) 2021
• Follow FAS’s work via their newsletter

I am honored to have hosted the podcast with the most intelligent people ever on any podcast in history. Erika, Alice and Zoë's backgrounds are very impressive! Be sure to click on their names above, or find them on LinkedIn to see what I mean. We are talking Einstein-level conversation at times, especially when Alice told us about triplet excitons. This is an exciting conversation!

Solar Project Development Software with Matias Sigal, Founder REplace

In this show we talk about the different stages of development of solar projects, which are projects that are from 1MW in size to GW sized projects.

 

Matias Sigal is an entrepreneur and has worked with many startups and incubators in different countries. He started off by being born in Argentina, and is currently a resident of Israel (which we discuss at the end of the podcast).

 

Matias has a company that developed software, which works sort of like Zillow for multimillion dollar solar projects. 80% of potential projects do not get developed, because they are missing some of the criteria. REplace can analyze thousands of potential sites at once, so that early stage developers do not have to spend 30 minutes per site analyzing things independently. His software can do over 100 years of hard work with the click of a button.

 

Some of the topics we cover:

 

8 stages of project development

Community Solar (contrasting with and not Community Choice Aggregation)

Agrivoltaics

GIS

Israel, Argentina and Europe

CapEx & OpEx
