Flexible solar panels are much useful as they help in many harsh processes where simple solar panel fails to work. Therefore, the solar panels are very useful and help in performing extremely powerful jobs. The solar panels are attached in a flexible way that nothing can harm it. The flexible solar panels are those silicon based flexible modules which passes very strict mechanical and aging tests. The flexible solar panels are very useful in emergency conditions. Therefore, they are suitable for grid-connected installations. These panels also provide solutions in off grid solar systems. They function in temporary installation like field hospitals, emergency tests etc. The flexible panels are also helpful in installation of solar system on the surfaces which are not completely flat. Marines also use flexible solar panel as these are very light weight, flexible, walkable, and extremely powerful and even resistant to harsh conditions of marines. Assemblies of photovoltaic cells are used to make solar modules which generate electrical power from sunlight. Multiple cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic module. The electrical energy generated from solar modules, colloquially referred to as solar power, is an example of solar energy.
Thin Film Flexible Solar Panels
Thin-film technologies reduce the amount of material required in creating the active material of solar cell. Most thin film solar cells are sandwiched between two panes of glass to make a module. These uses only one pane of glass and thin film panels are approximately twice as heavy as silicon panels. These were the first solar technology but this could not fulfil the need of flexibility in a system. The flexible solar panels are constructed with highly efficient solar cells supported in a unique polymer that allows for flexibility and significant weight reduction. These panels have no aluminium or steel backing like other semi flexible solar panels, which means they are extremely lightweight. These panels are used in many applications but the working process is same as that of simple solar systems. The sunlight is very important for the purpose of getting electricity for the appliances at home and at other places. The solar panel works only with the sunlight as the light and heat from the sun when strikes the solar panel, these panels start its conversion process. As this process includes intake of heat and converting that heat into electricity, this heat should be in abundance so that we will get electricity in abundance too. Installing solar panel at home is not an easy task. Firstly, the person will have to check the rules mandated by the state government in installing the solar panel. If the rules are ok then the other task is of checking if the communities around you are comfortable with its installation. The flexible solar panels came into existence when simple solar panels were not been used by many people because of its lesser use, due to higher cost and many other disadvantages. The solar panels are used where there is need of electricity from sun’s energy. The flexible solar panels also works on the same principle of converting sun’s energy into electricity but the difference is that in flexible systems there is not much limitations as this system could be attached anywhere and does not require special place to get installed. This system is highly powerful and very efficient than that of simple solar panel.
Advantages of Flexible Solar Panels
The following are the major advantages of flexible panels which make it different from simple solar panels:
- Life Expectancy: The life of flexible solar panels is much more than other simple solar panels. These panels will produce power for many years. It is the physical construction of a flexible solar panel that typically limits the lifespan of the panel. The construction factors include the integration of fabrics, plastics, and other materials that will degrade with use and exposure. The most important factor which helps in increasing life span of these panels is proper care and maintenance. It is important that the buyers should be aware of cheaply produced thin-film panels. The PV technology may be well crafted but if the panel construction is poor, the PV may become unusable in a very short period of time. However, life of a flexible solar panels is much higher than that of simple solar system.
- Operation: Most of the flexible panels are designed for single-device applications, like charging battery-operated devices or powering specific appliances. Adding panels is simple and allows the operator to scale the system up or down according to their power requirements; however, there is a limit to the scalability of a thin-film PV array. Connecting additional panels does not always provide an increase in power as many thin-film panels use small wiring, which will limit the amount of power it can safely conduct. Be sure to consult the thin-film panel manufacturer for information about addition of panels to an existing PV array.
Types of Flexible Solar Panels
The flexible solar panels are of different types as per volts for battery charging. The 3-4v flexible modules are great for integrating into your custom solar battery charger. With solder pads at both ends of the solar cells, it makes interconnecting the 3-4v flexible series modules a simple task. The 3 or 4 Volt flexible solar panels are great for small projects with kids and family members on the prowl for alternative energy needs. Each solar cell can be hand touched without damage. These panels are very useful for projects which include smaller household works and other smaller works.
The 6-7v flexible modules are great for integrating into your custom solar battery charger. With solder pads at both ends of the solar cells, it makes interconnecting of 6-7v flexible series modules a simple task. Each solar cell can be soldered on the copper tape at the end of each solar cell and all have an extra seal of weatherproof protection and adhesion. 12v OEM series flexible modules are great for integrating into your custom solar battery charger. With solder pads at both ends of the solar cells, interconnecting of 12v flexible series modules is a simple task. Depending on the size of your system, the use of the flexible solar cell accessories is recommended which allows you to attach extensions for longer reach from solar panel to solar battery. Each solar cell is designed to be singularly integrated in each solar cell allowing it to be more flexible than its predecessors. The panels should be chosen according to the following conditions like ruggedness, temperature dependencies, efficiency and surface area. Therefore, these are some of the uses and main functioning of the flexible solar panels. The main disadvantage of flexible panels is their higher cost. The cost of this solar panel is quite high. This system is used where there is much need of efficiency, power, and flexibility.
