Mistakes to Avoid When Using Solar Panels for Camping

Mistakes to Avoid When Using Solar Panels for Camping

Solar panels are a fantastic way to keep your devices charged and your campsite powered when you're off-grid. However, many campers run into issues that could easily be avoided with a bit of planning. Here are the top six mistakes to steer clear of when using solar panels on your next camping adventure.

1. Not Calculating Your Power Needs

One common mistake is not accurately estimating power needs. A quick way to calculate is by using amp-hours (Ah). Start by listing your devices and checking their current (amps) rating. For example, if you plan to use an LED light that draws 0.5 amps for 4 hours each night, you’ll need 2 amp-hours (0.5 amps x 4 hours) just for that light.

Do this for all your devices to get your total daily power requirement. This helps you choose the right solar panel and battery setup, so you’re not caught short or carrying unnecessary weight. With a bit of planning, you’ll have all the power you need for a worry-free camping experience!

2. Choosing the Wrong Panel Type

Not all solar panels are created equal, and choosing the right type for your camping setup can make a big difference. Solar blankets are highly portable and can be folded or rolled up, making them perfect for those who prioritize compact and lightweight gear. They’re efficient and easy to set up anywhere, but they tend to be more expensive than other types. This higher cost is often the only downside, as they’re otherwise an excellent choice for powering small devices like phones and tablets.

In contrast, foldable glass panels or fixed panels with aluminum frames are durable and can handle rougher outdoor conditions. However, they are generally heavier and bulkier, which can be a drawback for backpackers or those who need to travel light.

Flexible panels, meanwhile, are extremely lightweight and can contour to curved surfaces like tent roofs or vehicle tops. Their versatility makes them easy to incorporate into different camping setups. However, they may not be as efficient or durable as framed panels over the long term, which could be a consideration if you need sustained, high-output power.

Choosing the right panel depends on your camping style, budget and power needs. Understanding the pros and cons of each type ensures you’ll have a reliable power source, no matter where your adventure takes you.

3. Incorrect Panel Positioning

Simply placing your panel out in the sun isn’t always enough to maximize its output. Positioning your solar panel at the right angle is crucial to capture as much sunlight as possible throughout the day. In the Southern Hemisphere, aim the panel towards the north, as this orientation will generally receive the most direct sunlight. Adjust the angle based on the time of year; during winter, a steeper angle can help capture lower sun angles, while a flatter angle is better suited for summer months when the sun is higher in the sky.

If you’re using a portable panel, you have the advantage of being able to adjust its position throughout the day. By continuously facing the panel towards the sun, you can maintain optimal energy production as the sun moves across the sky.

Additionally, be mindful of shading. Even partial shading from a nearby tent, tree, or other obstruction can significantly reduce your panel’s efficiency. Set up in an open area where your panel will have unblocked access to sunlight for as much of the day as possible. Taking these steps will help ensure you’re getting the most power possible from your solar setup.

4. Ignoring Battery Storage Options

Solar panels only produce power when exposed to sunlight, but they don’t directly charge devices. Instead, they work by charging a battery, which then supplies power to your devices whenever you need it—day or night. This setup is essential for uninterrupted power, as the battery acts as an intermediary, storing energy from the panel and then providing a stable output for your devices.

By pairing your solar panel with a reliable battery bank, dual battery setup, or portable power station, you can ensure that your devices receive consistent power at night and during th day, even if the sunlight fluctuates due to passing clouds or temporary shade.

When selecting a battery solution, choose one with sufficient amp-hour (Ah) capacity to meet your needs and the flexibility to charge multiple devices simultaneously. Portable power stations, for example, often come with various ports and outlets, allowing you to power up anything from USB devices to AC appliances. Look for models with built-in safety features like overcharge and short-circuit protection to extend the battery's lifespan and protect your devices.

By setting up an efficient solar-to-battery system, you can make the most of your solar panels while ensuring a steady power supply throughout your camping adventure.

5. Not Allowing Proper Ventilation

Many campers overlook the importance of ventilation, especially when using flexible solar panels. While these panels love sunlight, they don’t perform well under excessive heat. Without proper airflow, the panels can overheat, leading to reduced efficiency and even potential damage.

Flexible panels without a frame can be particularly vulnerable, as they often sit flat against a surface like a tent or vehicle roof, trapping heat. To ensure optimal performance, try to elevate the panel slightly or place it on a surface that allows for airflow underneath. This will help dissipate heat and keep your panels operating at their best throughout the day.

6. Overlooking Maintenance and Care

Solar panels are built tough, but they still need proper care. Dirt, dust, and debris can reduce their efficiency. Clean the panels regularly with a soft cloth and water to keep them performing at their best. Also, handle the panels carefully to avoid damage, especially when packing up or moving between sites.


Avoiding these common mistakes will ensure that you make the most of your solar setup and enjoy a worry-free camping experience. Regardless of your camping experience, whether novice or pro, a little preparation can make all the difference in how you power your adventure.
