Types and Importance of Rechargeable Batteries
Solar lights are made of mainly three parts - a panel, LED lights source and a battery. Solar panel is a rectangular board embedded with series of semiconductors including amorphous or crystalline silicon metal chips. All the solar lights works on a simple principle which states that light rays falls over the solar panel. Sunlight provokes free electrons in semiconductors and free flow of electrons is used to generate electricity and finally charge the battery. These batteries can be used to illuminate LED lights, heat water, charge mobile phones or run any other electrical equipment.
Solar equipments are widely used in place of any normal equipment these days. The trend of 'Go Green' is popularly adopted by many people all over the world. Some families, hotels, colleges and other organizations have installed these equipments to save the non-renewable sources of energy used to generate electricity. Earlier, it was a scenario that solar equipments had a poor shell life and were like any useless things in winters or rainy day. Today, these equipments are supported with a rechargeable battery and efficiently works like other electrical devices.
Types of Rechargeable Batteries for Solar Lights
AAA Type Battery: AAA type batteries can be used to run any small electrical equipments. They are cylindrical in shape and small in size. Solar equipments which utilizes minimal power to run are designed with AAA type battery.
AA Type Battery: AA is used to define a standard size of battery. It is used in electronic equipments that are movable in nature. Both rechargeable and non-rechargeable versions of AA type are available in the market. The rechargeable version of AA Type Battery is mainly composed of Ni-Mh and Ni-Cd with a capacity to hold 1300-2700 mAh and 500-1100mAh respectively.
C Type Battery: These batteries are used to run medium sized electrical equipments.
D Type Battery: It is a heavy duty in nature used to run big electrical equipments. The Nickel-Metal Hydride version of D Type battery has capacity to store up to 12000 mAh of current efficiently. Due to its higher capacity, it can illuminate solar flood lights for a longer time period without lowering the quality of produced light.
In solar equipments, the main focus is to use a energy storage source durable and has a higher shell life. It must go to an auto-discharge mode in case when it is over charged. Auto discharge mode is necessary to increase the life of the battery.
Numerous spare parts re-sellers of solar equipments are available in the market. Online stores are selling high quality parts at reasonable rates. It is necessary to choose a company which provides guarantee with all the products and a lifetime technical support.
