Factors to Consider When Buying Flexible Solar Panels
Having a steady supply of solar power is essential when living off the grid, taking an extended RV trip, or going out into the ocean in a Boat. As such, it is crucial that you outfit your rig or home with the best bendable solar panels from the outset.
Here is a list of the essential factors to consider when shopping around for a flexible solar panel:
Build Quality of Flexible Solar Panel
Considering solar panels’ crucial role in ensuring a steady power supply while living off the grid, build quality matters significantly. You’re better off with a superior product that helps you harvest as much energy as you need from the sun.
Portable and flexible solar panels fall into two broad categories:
Monocrystalline Solar Panels
These are premium solar products with a high solar energy conversion efficiency, greater than 20%, and sleek aesthetics; the name Monocrystalline references the fact that the panels are made from pure, single-crystal silicon. High purity levels form the basis of their high solar energy conversion efficiency, distinct black color, long lifespan, and rounded corners.
To make monocrystalline solar cells, silicon is shaped into bars and then cut into small wafers. Since each section comprises a single crystal, the electricity generating electrons have a bigger surface that allows them to move more.
Polycrystalline Solar Panels
These panels have a lower solar energy conversion efficiency, about 15%, and carry a lower pricing point. Unlike the black monocrystalline panels, polycrystalline panels are blue. They have a lower lifespan since they’re susceptible to high temperatures.
Although made from silicon, the polycrystalline solar panel product process entails melting raw silicon to form wafers. The name signifies that each solar cell contains numerous crystals, which can also be referred to as multi-crystalline cells.
The presence of multiple crystals in a cell restricts electrons’ moment, leading to lower energy conversion efficiency.
The lifespan of the Flexible Solar Panel
The standard monocrystalline solar panels have a lifespan of more than 25 years, but the lifespan drops drastically for flexible solar panels. Due to their small size, bendable solar panels lack the protective aluminum and glass casing.
Instead, flexible solar panels are covered in polyester-based plastic, PET, fluorine-based polymer, EFTE, and laminates. These coatings cover and protect the solar cells from damage and extreme weather conditions.
The type of protective covering also influences the longevity of a flexible solar panel. A PET laminated solar panel has a lifespan of 5 years, while a cell laminated with ETFE can last for up to 10 years.
The efficiency of the Solar Panel
While a flexible solar panel’s efficiency covers many aspects, its charging efficiency should be your primary concern. You want a model that can charge your devices quickly and efficiently. Such a panel harvests sufficient sunlight to recharge your solar batteries and provides you with a reliable solar energy supply.
Monocrystalline solar panels tower over other varieties due to their high conversion rates and harvest solar energy in low light conditions. They will ensure that you never run out of power during overcast days or when it’s pouring.
Portability of the Solar Panel
Unlike their bulky cousin, flexible solar panels are designed for portability and convenience. You can affix these solar panels to the roof of your home, car, motorhome, golf cart, or even your tent.
Bendable solar panels are easy to install and take down, allowing multiple uses. Most frameless panels ship with pre-drilled holes with stainless steel eyelets for easy setup. You can fix them on your RV, sailboat, or trailer roof with Velcro, double-strength zip ties, or durable cords.
Conclusion of Flexible Solar Panels
Flexible solar panels are an excellent way to power an off-grid lifestyle or as a backup power source in your home. The best frameless panels are made of monocrystalline solar cells and have a conversion efficiency higher than 20%.
The flexible nature of a frameless solar panel allows for seamless installation on otherwise tricky surfaces. You can secure them on the sloping roofs of RVs, the curved surfaces of an airstream, or the uneven roof of a cabin roof.
These panels come in various wattage classes to suit different power needs and can power a broad range of electrical devices.
