Flexible Solar Panels

What are flexible solar panels?

A standard monocrystalline or polycrystalline solar panel is made up of silicon wafers. They are typically up to 200 micrometers thick, which is slightly thicker than a human hair. In order to make a “flexible” solar panel, those silicon wafers must be sliced down to just a few micrometers wide. Using these ultra-thin silicon wafers gives solar panels many unique properties, including flexibility for some models.

Flexible solar panels made of ultra-thin silicon cells have been around for a while. More recently, research at the Massachusetts Institute of Technology has given way to advances in organic solar cells. Instead of using silicon as the basis for solar cells, researchers have found a way to use organic materials with electrodes of graphene. Until now, a limiting factor on panel flexibility has been the brittleness of typical electrodes, but due to graphene’s transparent and flexible nature, this method may lead to thinner, more flexible, and more stable solar panels in the future than what we can currently make.

Thin film panels: a flexible panel option

The current flexible solar panels available to homeowners on the market fall under the category of “thin film panels.” A thin film solar panel is made with layers that are over 300 times smaller than standard silicon solar panels, which gives them a much thinner profile and can even make some thin film panels flexible. Thin film panels are lightweight and durable, and can be an intriguing option depending on a solar project’s needs.

Pros and cons of flexible solar panels

The biggest advantage of flexible panels is their ability to fit many types of solar projects. For example, if your roof can’t bear the heavy load of traditional solar panels due to structural concerns, lightweight flexible panels like thin film may be a great solution that won’t compromise your home’s structural integrity. Because flexible panels can be shaped to fit the surface they are installed on, they can be easily installed on less conventional structures like carports.

Financially, flexible solar panels will likely reduce the installation cost of your solar array. Flexible/thin film panels require less labor to install, and they are much more portable and easy to handle than typical panels, which can be bulky and heavy and require heavy-duty roof mounting systems.

The most common obstacle for thin film or flexible solar panels is their lower efficiency than classic panels. Today, the efficiency ratings for average monocrystalline or polycrystalline panels hovers between 14 and 17 percent. Thin film solar panels, on the other hand, typically offer an efficiency of between 11 and 13 percent. This lowered efficiency means that you will need more solar panels to produce the same amount of energy, which can be a barrier to some solar projects with limited roof space for installation.

Additionally, flexible solar panels aren’t a good fit for many home rooftop solar projects, because there may not be enough roof space to produce your desired amount of energy. Due to their durability and portability, flexible solar panels are best for small solar projects on surfaces such as RVs or boats, where they may experience physical wear and tear that would not occur on a stationary roof. Their durability combined with the reduced weight of flexible panels make them ideal for these smaller, mobile solar projects that don’t need large amounts of energy.
