  • Easy To Install: Solar panels from Harbor Freight are simple to mount and remove. Simply loosen the bolts, then lift the panels off.
  • Reliable: Systems with Harbor Freight solar panels are built to last for many years. You don’t have to be concerned about them being harmed by strong winds or torrential rain because they are designed to withstand extreme weather conditions.


  • A Bit Flimsy: You’ll probably need to make a few adjustments if you want to use the panels as part of a permanent setup rather than a portable one. For instance, while the kickstands that support the panels are perfect for quick assembly and disassembly, they aren’t sturdy enough to withstand severe weather.
  • Amorphous Panels: The solar panels are amorphous thin-film panels. These are less effective than the panels used in a typical home solar setup, but they are lighter.
  • Separate Inverter and Battery: The battery and inverter aren’t part of the package, which makes sense in light of the possibility that buyers already have them. But I prefer to purchase products that are ready to use right out of the box, without the need for any additional accessories. Even though it’s a small complaint, getting the entire package in one purchase would be great.
  • Charge Controller: Telling you how much charge is entering the battery is the charge controller’s primary duty. I had no trouble doing this, but some of the other functions left me perplexed. These weren’t immediately obvious, but they will probably become clear with more use.
