In this Unplugged LIVE replay, it is DIY solar trivia night. Adam De Lay runs the crew and the chat through 13 scored questions on panels, batteries, wiring, and safety while a live leaderboard builds all night. Perfect scores landed in the wheel of luck for a MidNite SPD giveaway, and @52gulfpapa took it home.

We also run the sunshine report with weekly solar production totals from around the country, answer a super chat about the EG4 string calculator, and celebrate the channel crossing 1,000.

Topics in this episode:

  • What actually powers a solar panel, and how irradiance is measured with a pyranometer
  • Series wiring and voltage math
  • Watt hour math at 50 percent state of charge
  • What a shunt does and why it matters
