Reviewing Harbor Freight Part #63585

Do-it-Yourself Solar Panel Kit

If you are camping or looking for ways to use renewable energy, there are quite a few options out there actually.
One of the best deals that caught our eye this week is Harbor Freight’s 100 Watt Solar Panel Kit by Thunderbolt Magnum Solar.

The item normally retails at $189.99 according to their ad however today I got a flier in the mail saying it’s on sale for $146.42. It promises 2x more power than? Well i’m not sure what. Perhaps their previous model? The item number if you’re interested is 63585. Here is one review.

What’s our final take on Harbor Freight 100W Solar Panel Kit?

If you’re looking at getting started you really can’t beat this price. More experienced users might be able to piece together a cheaper setup, however for the beginner solar energy fanatic, this kit isn’t a bad idea.


This isn’t your only option of course, there are some DIY Solar Panel Kits out there that might be worth checking out.
