INSIDE THE CLASS

What each belt teaches.

Eight belts, eight worlds. Here's a brief look at what you'll actually cover in class — alternating scenes from the course, one topic at a time.

White Belt class scene: two students meeting their energy team around a panel
White Belt

Your energy team

Meet the players: panels make DC power, inverters turn it into AC, batteries store it, and the grid backfills the rest. You'll practice the kW vs kWh difference until it's reflex — the first question every good customer asks.

Yellow Belt class scene: a student ninja explaining electricity with a glowing bulb
Yellow Belt

Electricity without the mystery

Voltage, current and circuit thinking — with real examples like why a sunny roof can still trip a breaker you sized wrong, and how to match an AC service without claiming compatibility you can't verify.

Orange Belt class scene: reviewing inverters and equipment paperwork on site
Orange Belt

Equipment, documents and warranties

Inverter architectures, MPPT and racking — then the pro skill: reading an actual spec sheet before promising anything. You'll compare two datasheets and spot what most salespeople get wrong.

Green Belt class scene: a rooftop site check with safety in mind
Green Belt

Roofs, safety and paperwork

Site qualification and roof planning, hazard recognition and stop-work judgment, plus permits and interconnection — the class where you learn that 'no' is a professional answer.

Blue Belt class scene: two students reading a commercial electric bill together
Blue Belt

Reading a commercial bill like a sensei

Line by line: load shape, demand charges and self-consumption — and how exports and tariffs change the math for a storefront versus a warehouse. Bring your own (redacted) bill to practice on.

Purple Belt class scene: learning the Tesla Powerwall with an instructor
Purple Belt

Tesla Powerwall, properly

The Powerwall family and backup architecture, runtime reserves and power limits, and operating it all in the Tesla app — the path to the Powerwall Product Knowledge Certificate.

Brown Belt class scene: working through estimates and cash-flow charts
Brown Belt

Honest money math

Production estimates with real uncertainty, cash-flow and incentive literacy with dated sources — you'll build a proposal that survives a skeptical CFO instead of one that dies at the first question.

Black Belt class scene: the capstone review and oral defense
Black Belt

The capstone and oral defense

Integrate everything on the warehouse capstone — full assessment, verification and troubleshooting — then defend your work in an oral review before your Black Belt is issued.
