The solar power battery answers many needs. With solar power rapidly becoming the wave of the future, many people interested in a renewable yet environmentally safe energy source, have many questions. How do solar panels work and how many do I need? How much will it cost to convert to using solar energy? How exactly does all of this really work?
People interested in converting their homes to solar energy need to know how to set up their systems for long-term and efficient use. In this way, they can break their dependence on fossil fuels and other pollution-causing energy sources and save money on energy bills. And that is where the solar power battery comes into use.
While everyone knows what solar panels are and what they do, few people understand what other equipment is needed to make a solar energy system work. The solar power battery is used to store the energy absorbed from sunlight for later use. This is important because the sun doesn’t shine twenty-four hours a day and even cloudy weather can have an adverse effect on how much energy is absorbed during a given time.
A solar power battery differs from other large batteries such as solar car batteries, in that they are designed to be charged and discharged frequently without being damaged. The most common type of solar power battery is the lead-acid deep cycle battery. Although they cost more than other batteries, they can last for ten to fifteen years if cared for properly and will be well worth the investment in time and money.
Be sure that when you purchase solar power batteries that it is the proper size for your needs. Otherwise, you will need to discharge it frequently and you may find yourself replacing it too often. A solar installer will be able to help you figure out the battery size you’ll need.
Another thing to be aware of is the battery’s depth of discharge. This tells you how much energy has been taken from a battery and a lead-acid solar power battery has a greater tolerance for discharge than a car battery. Typically you can discharge the battery by 50% to 80% without damaging it.
There are other types of batteries you can choose from. Each has benefits and limitations, however, and maybe more costly. These include, sealed flooded cell batteries, which are maintenance-free but may be damaged if you overcharge them; gelled electrolyte cells, which are easier to adapt for mounting but are more expensive, and recombinant flooded cells, which are more expensive, but safer since they don’t spill acid.
And speaking of safety: a solar cell battery can be hazardous, just like a car battery, and should be handled with care. According to statistics, there are thousands of serious accidents a year involving large batteries. Lead-acid batteries contained a diluted sulfuric acid electrolyte and it is dangerous in both liquid and gas form. Wear protective eyewear when working with the battery and always handle it with care.
Proper care is always needed. So be careful when switching to solar battery.
