Key Takeaways

Flexible Solar Panels

Flexible solar panels utilize photovoltaic cells to produce electricity, similar to regular rooftop solar panels. The main distinction is that their PV cells are from a flexible material rather than a rigid aluminum and glass structure. This allows flexible solar panels to be on curved surfaces or folded and stored.

They have a more compact and lighter design, with many options weighing less than 10 pounds. In comparison, traditional solar panels typically weigh between 35 and 50 pounds, with a standard height of 65 to 80 inches (5.4 to 6.7 feet).

Who Should Purchase Flexible Solar Panels?

Solar experts suggest using flexible panels for portable off-grid power with small appliances. They are ideal for camping trips, campers, boats, and off-grid communication equipment like GPS. Flexible panels have lower wattages than rigid ones, with the largest reaching 200 to 300 watts. In contrast, a traditional rooftop system with 15 rigid panels can get 5,000 to 6,000 watts. Flexible panels are unsuitable for powering large devices such as air conditioners or electric water heaters. A traditional rooftop installation is better to power an entire home.

Types of Flexible Solar Panels

There are three main categories of flexible solar panels depending on the material of their photovoltaic cells: monocrystalline, polycrystalline, and thin-film solar. As with any buying decision, each choice has its advantages and disadvantages.

Both monocrystalline and polycrystalline solar panels are from crystalline silicon, but there is a critical distinction between the two. Monocrystalline cells are from single-crystal silicon wafers, resulting in a uniform microscopic structure that leads to higher energy conversion efficiency. In contrast, polycrystalline cells are from silicon solidifiying into multiple crystals with varying orientations during a more straightforward manufacturing process. This results in a lower cost but also lower efficiency.
Since both types of silicon solar cells utilize crystalline material, they are rigid. To create a flexible solar panel, scientists put PV cells can into small rigid sections with foldable joints, or ultra-thin crystalline silicon cells can be utilized for increased flexibility.

Thin-film solar panels consist of a photovoltaic material layer applied onto a flexible substrate. Common materials used in thin-film panel production include cadmium telluride (CdTe), copper indium-gallium-selenide (CIGS), and amorphous silicon.

What’s the Difference Between Flexible Solar Panels and Standard Solar Panels?

Both flexible and standard solar panels utilize photovoltaic materials to produce electricity. Traditional solar panels are thicker and heavier due to their rigid construction and multiple layers of glass, making them more resilient in the long run. On the other hand, flexible solar panels, while potentially less durable, are easier to set up and are avilable in various applications.
There are two main types of flexible solar panels: thin-film solar panels, where the photovoltaic material is printed on a flexible surface, and crystalline silicon panels with thin silicon wafers that offer some flexibility. Currently, crystalline silicon panels are more widely used.

What Are the Benefits of Flexible Solar Panels?

Lightweight

Flexible solar panels are much thinner than traditional solar panels. This allows them to be flexible and bend to fit curved surfaces like RVs or boats, and it also makes them lightweight and easy to install on your own.

Cost-effective

One of the main disadvantages of traditional solar panels is their high upfront cost. Even with incentives, recouping the investment can take a long time. In contrast, flexible solar panels are available in 100-watt single-panel options for under $200, with larger 350-watt systems costing less than $1,000.

Installation flexibility

Due to their lightweight design, you can install flexible solar panels on surfaces that traditional solar panels cannot support. They are trendy for boats, camper trailers, RVs, and smaller residential applications like worksheds or detached garages.

What Are the Downsides of Flexible Solar Panels?

Less effective

Typically, standard top solar panels have an efficiency of 20% to 23%, while flexible solar panels range from 7% to 15% efficiency. This means that there is a need for more flexible solar panels would be needed to produce the same amount of electricity.

Limited power output

Most flexible solar panels can generate up to 150 watts, compared to 250 to 300 watts for standard solar panels. While 150 watts may be sufficient for smaller applications like boats or RVs, it may not be adequate for powering a home.

Restricted warranty coverage

While standard solar panels require a significant initial investment, they often pay for themselves long before their lifespan expires. This is why most standard solar panel manufacturers offer 20 years or more warranties. On the other hand, flexible solar panels are not as durable and may only come with warranties ranging from one to five years despite potentially operating for more than 10 years. Less

Efficient

Typically, the average efficiency of traditional top-tier solar panels ranges from 20% to 23%, while flexible solar panels have an efficiency of only 7% to 15%. This means you would require more flexible solar panels to produce the same amount of electricity.

Limited Power

Most flexible solar panels available in the market have a maximum output of 150 watts, compared to the 250 to 300 watts produced by standard solar panels. While 150 watts may be sufficient for applications like boats, RVs, and other smaller setups, it may not be adequate for powering a household.

Restricted Warranties

Despite the higher upfront cost of standard solar panels, they tend to pay for themselves long before the end of their lifespan. This is why most manufacturers of standard solar panels provide warranty coverage of 20 years or more. On the other hand, flexible solar panels are not as durable and are more susceptible to damage from the elements. While they may still function for over 10 years, their warranties typically only last one to five years.

Printed flexible solar achieves efficiency records.

CSIRO, an Australian research center, has achieved an impressive milestone by creating a novel technique for manufacturing flexible solar cells using roll-to-roll printing. This technique provides a higher efficiency level, allowing for more power from the same amount of sunlight.
Although the new method has successfully produced small solar cells in laboratory settings that match the efficiency of standard solar panels, scaling them up is necessary for practical use.
The breakthrough lies in achieving 11 percent efficiency for large-scale solar panels measuring 50 cm2, comprised of interconnected solar cells.

Energy efficiency through perovskite and printing presses

Solar panels, the backbone of the renewable energy industry, have conventionally utilized silicon to absorb light. Despite the success of this technology, the search for new advancements is ongoing.
Introducing perovskite – an impressive category of emerging materials for solar cells that can be turned into inks and printed using commonly available industrial printers. Perovskite may present a more cost-effective and energy-efficient option for making solar cells than traditional silicon-based ones. It is light and flexible, allowing easy portability to power devices on the move, and has a wide range of potential uses.
The cells are printed using a roll-to-roll method similar to how newspapers are printed, enabling continuous and large-scale production. Although the production of perovskite solar cells using roll-to-roll technology is not new, current methods have faced challenges in efficiency and scalability.

Solar cell screening accelerates innovation.

The key to their success was implementing automated fabrication and screening systems that quickly maximized the potential of this technology. Their team utilized a cutting-edge system that could manufacture and test over 10,000 solar cells daily, a feat impossible with manual methods. Through this innovative approach, they swiftly identified optimal settings for different parameters, resulting in significantly improved efficiency.
