They are different types of batteries and consequently uses for these batteries. Some like car batteries are designed for quick discharge followed by long slow recharge. . Other batteries are designed for hours of use followed by a quick recharge in just a few hours. Those types of batteries are used for devices such as golf carts. These are known as deepcycle batteries. These are the recommended type to use in a solar system but the size will depend on your needs. So the use to which the batteries are put will dictate how much solar power it takes to recharge them which will in turn dictate the solar panel to be attached to these batteries.
After all solar power can be used to recharge many types of solar power batteries from the consumer level AA batteries all the way up to 48 V batteries. Some of those batteries are designed for only a few hours usage and others are designed for years of usage. Whether you get a single battery or have many batteries in a bank and whether the battery will be located inside or on the exterior also play into which of these solar power batteries you purchase.
Solar Power Batteries for Off Grid Uses
If you are interested in an off grid system you will want to have a large array of solar panels producing 12 V or 24 V power to charge your solar power batteries. And inverter then converts the power from DC to AC. There are lots of solar power batteries available to you but it is important to note that these are not car batteries or normal consumer type batteries because those batteries are designed for different applications other than solar power. For larger solar applications where you are powering your entire home rather than a single device you would want to get flooded lead acid batteries or modern lithium batteries for deep cycle performance.
AA Rechargeable batteries
The American National Safety Institute (ANSI) standardized the double A size of battery in 1947. At the time, household electronics were an emerging field. ANSI stepped in to standardize things and the end result is that today, you don’t have to comb the earth to find the right battery for your camera, or remote. AA batteries can be found in cameras, compact disc players, mp3 players, video game devices, GPS systems, etc. These batteries evolved from Primary batteries which were not rechargeable to the LSD batteries that are rechargeable. The rechargeable batteries have the same components as the primary batteries. They comprise of a positive electrode, a negative electrode, a separator and electrolytes (chemical solution). But, unlike primary batteries they can be easily recharged and used again anytime you want. This include NiMH batteries and NiCd batteries.
An effective use of these batteries in in Solar lights. Solar lights use rechargeable batteries that are powered through a small solar panel fitted into the solar light. It is charged through out the day to provide power all night long. They can be charged for more than 1000 times and used again. However, in the initial stages, using these batteries can be a little difficult as their power drains out without any alarm or sign. Thus, you always need spare batteries which can help you continue with your work while the other set of batteries get charged.
However, the newly manufactured NiMH rechargeable batteries have the same life as the primary batteries and can be charged as efficiently as the basic rechargeable battery systems. These LSD batteries can outlast the normal alkaline batteries. The LSD batteries are available in AA, AAA, C, D and also 9 volt sizes. Among them, the C, D and 9 volt batteries that are not very easily available. However most Solar Lights just need Standard AA 1.2v battery.
The Solar Battery Charger or Panel
A solar battery charger is a charger that uses the sun’s power to produce electricity which is measured in watts There are a variety of uses for this type of charge.
A low wattage solar battery charger ( generally 4 watts or under) are all small and designed to maintain batteries that do not have a load being put on them while being charged. The output of these low wattage devices is so small that they are not designed to recharge drained batteries. This type of is designed for maintenance of power sports and marine starting batteries. These devices might have stands, some are mountable, and some are panels that plug into car cigarette lighters.
A mid-range series is approximately double the wattage of the previous category. In these you could have panels, mounting stands or cigarette lighter adapters. This type of solar battery charger, which is typically 5 to 10 watt, is recommended for usage in such applications as industrial gate openers, electrical fence chargers and smaller industrial equipment
A solar battery charger of 11 W and up begins to have real capabilities for marine and industrial use and are often used for charging RVs and boating applications. Once the solar battery charger output of 11 W it up is reached then serious work can be done for recharging. For example solar battery charger panels range from 20 watts to more than 300 W. The solar battery charger panels can also be wired together either in series or parallel for many different applications.
Another specialized solar battery charger application is for RV and marine multi-battery charging and there are multiple output panels ranging from 62 watt to around 130 watts in this category.While a it can be simply put on the dashboard of a car and plugged into a cigarette lighter, most solar battery chargers need accessories to fully achieve their usefulness. Charge controllers are on off switches that will prevent a battery from being overcharged by shutting off charging when the battery is full.
A solar battery charger can also be used in off grid applications and for almost any consumer device you can imagine. For example laptop computer, for those times when you are off grid but still need to recharge your laptop’s batteries. And the RV and marine applications are perfect examples of obtaining power from the sun’s rays when electrical connections are not available. An easy way of thinking about this battery charger is to envision them as alternatives to plugging a charger into a wall outlet. Solar chargers create their own electricity rather than taking electricity from the grid. So you can be using the grid for most electrical applications while still using the free power of the sun to recharge many devices. So it can be either an adjunct to or a replacement for the electrical power from your wall socket depending upon what you want to achieve.
