Solar panels can be the perfect option you are looking forward to in order to bring a new way of generating energy to your home. Not only is it a much-needed source of reliable energy, but it also reduces, sometimes greatly, your energy bills and has very low maintenance costs. Nonetheless, finding the right solar kit in the vastity of options might be overwhelming.

In our article, we are going to talk about Harbor Freight solar panels. It is a discount tool and equipment retailer and sells a variety of solar kits and other products related to solar power. We are going to honestly review the most popular to give you an idea and orient you towards the best choice.

Harbor Freight Solar Panel Kit

Let’s first focus on Harbor Freight solar panel kits. The company is currently selling two of these products: the 7 Watt and the 100 one.

100 Watt Solar Panel Kit


This product is the retailer’s top pick and is recommended by 97% of their customers. It is a portable and reliable solar energy kit that delivers 100 watts of free, clean, and quiet energy. The cells work perfectly well in different weather conditions, including in both sunny or cloudy circumstances. Such advantage comes from the fact that the cells are in amorphous silicons, so you can be sure they will give you the best output regardless of the sun’s presence or absence.

The kit is also very simple to set up and then maintain. The reason being, it comes with a set of tools such as mounting hardware, a 12v light kit, battery terminal clamps, and a universal power adapter. These tools make it easier not only to place the panel in the desired place but also to keep it in good condition.

To guarantee the best performance, the panel uses technology such as solar charge controllers or blocking diode technology, which prevents your panel from losing charge during the night. This happens because it allows the flow of current to the battery but blocks the opposite flow of current, i.e., from the battery to the panel.
