In this episode of Electronic Basics I will show you how solar panels are wired up, why bypass and blocking diodes are necessary when working with them and how we can get the most power out of them. At the end I will also show you how MPPT and PWM charge controller can use a solar panel to charge up a battery.

Check out our new Guide to Van Life:
- We installed a 300 Watt solar system in our stealth campervan and we love it! It makes living in a van much more comfortable, especially since we’re also working in the van!
We’re using Renogy’s flexible (bendable) 100 Watt panels, a 40 amp MPPT charge controller, a 500 Watt pure-sine inverter and a 155 ah Deep Cycle AGM battery from VMAX. Watch the video to check out how we installed it!
If you want more information about the components, prices, etc., check out our blog post about the solar panel system here:
Thanks for watching!
