The Lead Acid Battery Disadvantage of Solar Energy

Is the eventual need to replace

Lead Acid Batteries

If your solar power system is off grid, chances are you have a bank of deep cycle lead acid batteries.

Batteries are the one component of an off grid system that require fairly frequent replacement.

How frequent depends on several factors including:

  • Temperature
  • Level of Charge
  • Water levels
  • Depth of Discharge /Charge
  • Sulphination
  • Frequency of use
  • Size of battery bank

Yes, it turns out that as far as deep cycle battery banks are concerned, size does matter.

Getting the most use out of your batteries works for you and the environment.

Environmental Disadvantage of Solar Energy Storage

Lead Acid batteries are largely composed of Lead and Sulphuric Acid. The improper use or disposal of either rings environmental bells. And so it should.

Soil and water and ultimately, human beings can become contaminated due to damaged or improperly disposed of batteries.

Inhalation and ingestion of lead dust or residue causes serious health risks.

Lead interferes with the body’s ability to oxygenate itself. In children it affects brain and nervous system function and can lead to death.

Fortunately the materials in lead acid batteries are 98% recoverable if the battery ends up in a recycling facility. The plastic, steel, lead and acid are all re-incorporated into batteries or other products.

Batteries will have to be replaced. The number of years between replacement depends a great deal on how and where their life is lived.

Keeping your batteries healthy assures that the disposal issue crops up as little as possible.
