Best Flexible Solar Panels  For RVs and Marine Boats

Factors to Consider When Buying Flexible Solar Panels

Having a steady supply of solar power is essential when living off the grid or taking an extended trip on your RV 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

Given the crucial role that solar panels play in ensuring a steady supply of power while living off the grid, building quality matters greatly. 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 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 each solar cell contains numerous crystals, so they 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.

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 the 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 a 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.

Efficiency of the Solar Panel

While a flexible solar panel’s efficiency covers many aspects, it’s 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 on the roof of your home, car, motorhome, golf cart, or even your tent.

Bendable solar panels are easy to install and takedown, which allows for 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 source of power 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 RV, 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.
