Best Spots and Directions for Placing Portable Solar Panels


Identifying cost-saving opportunities is crucial for those seeking to reduce their electricity bills over the long term. One strategy is to acquire portable solar panels and utilize them to recharge various electronic devices. However, selecting the ideal location to install these panels is critical.

Why is placement so critical? If portable solar panels are not positioned correctly, they will not generate enough energy. Additionally, they must be situated in a location that receives ample sunlight throughout the day to function effectively.

Let us explore the optimal and suboptimal locations for installing portable solar panels.


Key Components for Optimal Energy Generation from Mobile Solar Panels

In regards to mobile solar panels, there are some critical components to keep in thought for prime energy generation. Let's explore and guarantee your panels are in the correct location!

Availability of Sunlight

This is an easy one. Mobile solar panels change sunlight into electrical power, so it's essential to place them where they can get the greatest sun exposure. Target a location with immediate sunlight between 10 am and 4 pm, when the sun is at its highest and most intense.


Energy output from mobile solar panels declines when shadows are present. Therefore, it's necessary to prevent areas with overhead structures that could throw shade on your panels, including trees and buildings, as this will decrease their efficiency. Find a location with as little shadow as feasible, particularly during the middle of the day when the sun is at its maximum intensity if you can't evade the shadows altogether.


Panel direction also matters! Since the sun rises and sets in the west, it is best to face portable solar panels towards the east to get the most exposure to the sun. Similarly, if you are in the northern hemisphere, portable solar panels facing northward will receive the most sunlight. Therefore, if you have mounted your portable solar panels on your car while on the go, make sure they are pointed in the right direction when you park. Additionally, when camping or resting, aim to position your portable solar panels in the direction that receives the most sunlight.

Angle of Inclination

This refers to the angle at which your panels are positioned relative to the ground. The optimal angle varies depending on the seasons and your location, but a good rule of thumb is to angle your panels equal to your latitude during the winter and at a higher angle during the summer when the sun is higher in the sky.

To determine the ideal tilt angle for your solar panels, you can use a simple calculation that takes into account the season and your location. During the winter months, you can subtract 15 degrees from your latitude, while you add 15 degrees during the summer. So, if you are located at a latitude of 34°, the recommended tilt angle for your solar panels during winter would be 19°, which is calculated as 34 - 15.

Weather Conditions

Mother Nature can sometimes be unpredictable, so choose a location that is protected from heavy rain, snow, and clouds. If camping, try to find a sheltered campsite or a camping shelter. If using your panels at home, make sure they are shielded from the elements to keep them functioning at their best.

By taking these factors into account, you will be well on your way to utilizing your portable solar panels and capturing the sun's energy.
If you're looking for ideas on where to place your portable solar panels, there are several options to consider. Here are some of the most common placement ideas:

On the Ground:

Placing your portable solar panels on the ground is a quick and easy option. This is a good choice if you need a solid surface to mount your panels or if you want to move your setup around easily. Just make sure your panels are level and securely positioned.

On a Roof or Patio:

Another option is to place your panels on a roof or patio. This provides a permanent home for your portable solar panels and eliminates the need to move them around frequently. When installing on a roof or patio, it is important to ensure that your panels are securely mounted using the appropriate hardware.

In a Garden or Backyard:

If you have a garden or backyard, this can be a great spot for your portable solar panels. This location provides a secure spot for your panels and still allows for flexibility to move them around as needed. Just be sure to position your panels in a sunny spot for optimal exposure.

On an RV or Camper:

If you enjoy road trips and spending time in nature, you may want to consider mounting your panels on an RV or camper. This way, you can harness the power of the sun and generate energy while on the go. Just make sure that your panels are correctly mounted and protected from the elements, such as high winds and rain.

Maximizing Portable Solar Panel Output

Now that you've learned about the factors involved in positioning portable solar panels and the common placement ideas, let's take a deeper look at maximizing their output by leveraging peak sun hours.

Understanding Peak Sun Hours

Peak sun hours are the hours during the day when the sun is at its highest point in the sky and shining down with maximum intensity. This is the prime time for your solar panels to generate the most electricity. However, the number of peak sun hours can vary based on factors like the time of year, your location, and weather conditions, as mentioned earlier.

Finding the Best Times for Peak Sun Hours in Your Area

To determine when your peak sun hours occur, you must look at the sun's path across the sky, which changes throughout the year due to the Earth's orbit around the sun. To stay informed, you can find up-to-date information on the sun's position at different times of the year through online resources specific to your location. One such resource is the National Renewable Energy Laboratory's PVWatts Calculator, which provides an average of your area's peak sun hours throughout the year.

Maintaining and Cleaning Portable Solar Panels

Have you acquired portable solar panels and wish to guarantee their optimal performance at all times? Beyond knowing the best peak hours, a few additional steps are necessary to maintain their optimal capacity. You must take specific measures to keep them clean and well-preserved.

To begin with, how frequently should you clean your portable solar panels? This depends on your location. If you are camping in a dusty region, it is ideal to clean your panels every week. However, if you are in a more humid environment, a monthly cleaning should suffice. Just keep an eye on your panels and provide them with a gentle wash when you notice a buildup of grime and debris.

So, what do you need to clean your panels? It's quite simple! You'll require a soft-bristled brush, a clean cloth, and water. If you're in an extremely dusty area, consider bringing a vacuum cleaner with a soft brush attachment.
When you're ready to start cleaning, use your brush to get rid of any large debris. Then, use your damp cloth to give your panels a delicate wipe-down. If there are any persistent stains, use a little water and your brush to scrub them away. Lastly, use a dry cloth to eliminate any remaining moisture.

One thing to remember: avoid using severe chemicals or abrasive materials to clean your panels. These can harm the panel surface and decrease their efficiency. Stick to water, a soft brush, or cloth. Additionally, when not using your panels, keep them in a cool and dry place to prevent dust and debris from accumulating. This will also protect your panels from damage. If you need to store your portable solar panels outside, make sure to cover them with a protective covering.

Lastly, inspect your portable solar panels regularly to ensure that everything is functioning correctly. Monitor their output and ensure that the cables and connections are tightly secured. If you detect any issues, have them repaired as soon as possible to avoid further damage. And there you have it! A few straightforward measures to maintain your portable solar panels at their best.

Achieving Optimal Solar Panel Placement

If you are genuinely committed to solar energy, it's worthwhile to invest some time in ensuring your panel placement is optimal. This decision requires consideration of several factors, but with careful planning, you can significantly increase the energy derived from the sun, thus reducing your long-term energy costs.
