- 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:
