What to Consider Before Purchasing the Best Flexible Solar Panel
In the modern-day, energy supply is a quite huge subject. And since we have noted that most people get confused when looking for a tractable solar panel for their home, we have highlighted a few essential factors to consider next time you shop.
Energy is a critical feature that you should check before purchasing the ideal solar panel. While the power output may vary from one flexible solar panel to another, the higher the wattage, the better, as you can plug in more devices for a longer period.
If you want to buy a solar panel for your trailer or camper van, first find out the amount of energy you need. You can start by determining the number of solar panels you will require.
While boats require a 100W flexible solar panel, RVs or off-rigid cottages might need between 200 to 300- watt products. In short, a 400W solar system is more than enough for your camper van.
In this case, efficiency refers to how fast a model can convert sunlight into energy. So, the best flexible solar panel should be able to charge fast and proficiently. It doesn’t matter whether you’re on the road in your RV or on steady sheds; your solar system needs to gather sunlight sufficiently to keep your devices and gadgets up and running.
Just like power supply, efficiency varies from one model of a solar panel to another. However, most unit ranges from 10% to 25%. The greater the percentage, the faster your device will generate energy from the sun. But that shouldn’t be a big concern because most flexible models provide impressive efficiency.
A flexible solar panel should not be complex to install- such models are super easy to set up because they come with pre-drilled mounting holes. Also, they include tools like a drill bit kit, hand drill, wrench, and a sealant to make the installation process a breeze. However, don’t hesitate to ask for help if you get stuck.
Before you shop for a flexible solar panel, ask yourself what you will be using it for. Are you an RV enthusiast, and you need it for your van’s roof, or you’re a camper and want one for your tent? It would be best if you had a solar panel that will meet your needs.
For instance, if you drive a travel trailer, especially through desert-like areas, you might want to buy a solar panel that can withstand high temperatures. A model that uses amorphous cells will perfectly suit you because it can perform better in extremely hot environments.
Durability and material
It is important to consider the quality of material construction if you want your flexible solar panel to serve you for several years. Material quality goes hand in hand with durability, so make good use of your money.
You’ll find that a durable solar panel is built with resilient plastic to ensure the solar cells are not filled with moisture and dust.
Most flexible solar panels are built with ETFE plastic, a standard material to provide better light transmission and durability than other cheaper alternatives like PTE and PET. Also, bear in mind that a crystalline solar panel is much tougher than a solar panel constructed with thin-film technology.
Considering the model’s versatility is important as well. Most flexible solar panels have wide application areas and are already versatile, but always ensure your model is more versatile. For instance, you can install ultra-flexible panels nearly anywhere due to their stable construction. They will never disappoint you in any situation, even when you’re on the go.
Similarly, a waterproof solar panel allows you to use them in moist/wet conditions-meaning even heavy rainfall cannot damage your model’s sensitive electronics. So, choose a versatile product.
