It’s a beautiful spring day and the perfect time to install a solar system in my teardrop camping trailer for endless energy and ham radio off-grid camping (read more about the special offer). . .

UPDATE: After a few months, here’s my impression on how my solar system is performing:

About the Install: I used a 180 watt BougeRV mono-crystalline solar panel supported by two five foot pieces of aluminum strut on the roof rack of my TC Teardrops 5×8 camping trailer. Panel cable ran down the front of the trailer, underneath to where a connection took the cable inside the cabin and back to the galley. The controller is a DIY Solar for U Sol Buck/Boost 20 amp MPPT solar controller and a Renogy 50ah LiFePO4 battery.

DIY Solar for U Sol Buck-Boost 20 amp MPPT Solar Charge Controller

I think the key to a right sized solar system is in the charge controller. There are a lot of charge controller choices out there, but they boil down to two different styles: PWM or Pulse Width Modulation and MPPT or Maximum Point Power Tracking. Both have advantages and disadvantages, and I’ll talk about them in a bit, but for the trailer project I choose an MPPT charge controller from DIY Solar for U.
