What to Look for in a Solar Battery?
When it comes to solar batteries, there are two basic types. One is the flooded lead acid batteries, which are cheaper. They also tend to last longer. The downside to them though is that they do require maintenance to continue working as they should. The other type is a sealed battery. These batteries require no maintenance, but what makes them great is that they do not emit any of the corrosive fumes that may come from the flooded lead acid ones.
You will also want to consider the amphours or amperage of the battery you are looking at. Pay attention to the numbers. Most batteries have a capacity listed such as 100 amphours (c10), which means that it starts at 100 amp and then discharges over a 10 hour period. If you have a battery that says 100 amps (c100) then it will slowly drain out over 100 hours of use.
To decide which battery you need, you will want to figure out how much power you may need ahead of time. If your home or boat uses solar power and it is often cloudy more than sunny, you may want to choose a battery that drains out slower. If you have ample sun or a backup power supply that you can depend on, you may be okay with it draining out in a shorter amount of time. Either way, you first need to know the amount of amps you need to have all your gear run efficiently.
How Solar Panels and Batteries Work
Understanding your solar panel and battery system may also be important when it comes to finding the right battery. When using solar power, energy from the sun’s energy is collected within the solar panels. The solar panels are covered in a layer of material that produces both positive and negative energy to create an electric field, which builds up heat. The heat is then transferred into energy. This energy is then transferred to an inverter that makes it usable in your home or boat through the regular AC outlets. When enough energy is collected, it can be stored for later use, during the night, on less sunny days, etc.
Often when it comes to a solar powered home, office, or other large area, you will have a battery bank which is a lot of batteries that are all comparable in size and amps. This solar battery storage area will fill up with power throughout the day and hold it until it is used. On the next sunny day, your batteries will once again charge.
Are Marine, Auto, RV Batteries Compatible With Solar?
If you were to find a quality battery that can handle a deep discharge/recharge cycle on a daily basis, then it does not matter what type of battery you use for solar powered items. This could be automobile battery, golf cart battery or even an RV battery. However, as a general rule, you may not get as much life out of these type batteries. If you want economical, there are many who say that golf cart batteries are best, but you need to be prepared to buy a few at one time and pair them up.
