The best flexible solar panels must have good conversion efficiency and can be bent to a 30-degree arc without damage, these are the most important features for the best flexible solar panels. With that two important features, the flexible solar panels can be applied to more irregular surface applications, such as RVs, Boats, Cars, Marines, campers, and Vans.
What is more about the best flexible solar panels?
In addition to the above two features, another two features that are also very important, there are Service Life and Cost performance. In general, you should know the following four features about the best flexible solar panels.
1, Conversion Efficiency
Generally speaking, flexible solar panels are made from monocrystalline silicon wafers and laminated materials. The conversion efficiency of monocrystalline silicon wafers is uneven on the market, basically between 15% and 25% efficiency, usually the conversation efficiency less than 19% silicon wafers are not suitable for making the flexible solar panels.
Currently, the most efficient monocrystalline silicon wafers are produced by American brands, some solar cells have a conversion efficiency of 24% or more, but it is slightly more expensive than others. Usually, we purchase high conversion efficiency solar panels because of insufficient space, beautiful and practical performance. In addition, there are many Chinese monocrystalline silicon wafers have the efficiency of 19% or more, it is good enough to use it to build flexible solar panels. Although the conversion efficiency is low, it is also welcomed by users.
Base on this flexible solar panel that needs to be mounted to irregular surfaces that are on Vans, Cars, Home roofs, so it must be a little flexible and bendable. However, in fact, there are many mono-crystal flexible solar panels cannot be bent to a large arc, especially the mono flexible solar panels come from China, there are preferably not bent more than 20 degrees arc, otherwise, it is very easy to damage the monocrystal silicon inside, and it will affect its conversion efficiency, current and voltage outputs. However, some brand monocrystalline wafers are capable of bending at 30-degree arc without breaking. So, you should select the flexible solar panels for your applications very carefully.
3, Service Life.
If the flexible solar panels are installed and maintained properly, the service life can last more than 10 years. There are two types due to the production process, one is PET laminated and another one is ETFE laminated solar panel. ETFE solar panel is better than PET’s because it has better corrosion resistance and makes it more suitable for applications at sea, such as RVs, ships, sailboats, marines, boats, etc, and ETFE service life is longer than PET, but the price is much more expensive than PET.
The price/performance ratio of the flexible solar panel is mainly reflected in the wholesale price, and the wholesale price is actually mainly reflected in the cost of raw materials. PET laminated solar panel is much cheaper than ETFE flexible solar panel, but we strongly recommend the ETFE panel to use in the applications at the sea. Compared with the US solar cell, the most cost-effective is the monocrystalline silicon wafer of no less than 19% efficiency comes from China. Although the conversion efficiency is low, the price/performance ratio is the best.
