We’ve taken the time to compile a list of the best portable solar panels available on the market for you to consider

How Does a Portable Solar Panel Work?

It is without a doubt that solar energy is a growing trend that’s first used by those who are determined to eliminate their carbon footprint and lead cleaner lifestyles. This technology is beginning to be noticed by more people, especially those who follow more mainstream technology trends. Solar energy takes advantage of the energy that surrounds us on a daily basis through the use of many smaller cells called photovoltaic cells that are able to absorb light.

These photovoltaic cells have the ability to convert energy from the sun into usable energy and create electricity for our devices. These cells are composed of two pieces of semiconductive material with opposite charges. These opposite charges work to create an electric field. When the photovoltaic cells are laid out in the sunlight, they will absorb photos and generate electrons. These electrons are then gathered at either end of the cell by metal plates and transferred to our solar panels through a wire to generate electricity.

Portable Solar Panel Buying Guide – Factors to Look Out For

Choosing the best portable solar panel may not be rocket science, but there are a few details that you should look into as they will influence your decision.

Usage

The first factor that you should consider is the usage. What do you plan on using your solar panel for and how often. Depending on the purpose of your solar panels, you might even need to change your search parameters.

For example, the best solar kits for RV’s are generally around 100 W size and feature simple installation. Installing these solar panel modules should only involve more than a couple of wires. These portable solar panels are generally connected to lead-acid batteries that will recharge over time, so it is also necessary for you to select a proper battery pack and charge controller to fully charge up and meet your off-grid supply needs.

Boats require larger solar systems where the battery pack can be used to supply energy to appliances that are larger than a laptop or smartphone. An important consideration with these systems is to ensure they’re water-resistant or waterproof marine solar panels for obvious reasons. Moisture accumulated between the aluminum frame and glass can lead to solar cell delamination. Hence, good water resistance is essential in these cases.

Weight

Weight is another critical aspect to look out for, especially if you’re camping and require something lighter for better portability and comfort. Portable solar panel kits must also be ultra-lightweight if you plan on taking them with you on hiking. Some low-weight solar charges and folding solar panels even include USB ports for phone charging.

Efficiency

Obviously, one of the most important things to look for is the solar panel’s efficiency. Efficiency values refer to the energy conversion rate from solar energy into DC electricity. The higher the efficiency value, the smaller your solar panel can be to still generate the same power output.

Efficiency is one of the most valuable assets and indicators. The higher the efficiency, the lower weight, less surface area, and better quality performance of the solar panels.

Technology

There are varying solar technologies on the market with the crystalline technologies being the most popular ones in the grid-tied and off-grid markets. They have the largest market share and can be categorized into polycrystalline and monocrystalline modules. It is advisable for you to choose monocrystalline technology since it is established as the most efficient one.

Thin-film technologies also make for good contenders mainly for their flexibility and compact size. The disadvantage for them is their lower efficiency values compared to monocrystalline. Nonetheless, they’re more favorable in terms of maneuverability and portability.

Frequently Asked Questions

Q1. How to use solar panels?

Portable solar panels may look intimidating at first, however, the process to use them is actually very straightforward and simple. Simply follow the instructions laid out in the instructions manual to assemble it. Once you’ve got it set up, you can place it in a sunny area and connect the cords to your RV, camper, home, or other devices to begin converting energy.

Q2. How to properly clean the panels?

Dust and dirt can radically affect the performance of the solar kit because they reduce the amount of light that the solar cells can absorb. While portable solar kits are reliable, they do require some attention. Taking care of your panels means doing a little maintenance every once in a while. But rest assured, cleaning can be done anytime and since the device is very small, it won’t take more than a few minutes to do so.

You simply need to use a soft brush or sponge with a little bit of water to wipe down the panels. It is not recommended for you to use detergent, chlorine, or any other type of liquid as they may contain abrasive chemicals that will damage the encapsulating materials and may even lead to solar cell damage. Just apply water to the soft brush and start cleaning the surface area of the glass.

Among other valuable cleaning, tips are to avoid high-pressure water. Solar power systems on rooftops may need a hose to do the cleaning, but the water pressure is not the same for a rooftop solar panel system as it is for a portable solar kit.

Q3. How to secure your panels so that they don’t fall over?

Folding solar panels need to be constantly mounted and dismounted, hence a simple and comfortable installation process is one of the most crucial aspects of their design. To install it, it’s as simple as opening the kit, unfolding the panels, adjusting the legs to provide proper tilt, then setting the controller that’s already mounted behind and connecting the output to the 12 V batteries. These panels are already quite secured themselves and do not need any additional support.

Flexible panels can be easily secured with an eternabond tape and a little bit of Velcro attached to the backside. Another good idea is to install a window which you can make with PVC tubes, L and T PVC pieces, as well as some stainless steel screws. Attach the 4 L PVC pieces to the four corners of the panel and the two T pieces to act as the PVC legs, then use suction cups to attach them to the window and set the right tilt angle by using the PVC legs.
