The Ins and Outs of Recycling Solar Batteries | Simply Solar
Solar energy is praised as one of the greenest renewable energy sources for commercial and residential properties. Property owners are quickly making the switch to solar energy in order to reduce their impact on the environment and save money. However, now homeowners are asking the question “Are solar batteries recyclable?” 

The Lifespan of Solar Batteries

Solar batteries can last a long time, ranging from 5 to 15 years. The true lifespan, however; depends on the battery itself. The battery’s manufacturer will provide a warranty that accounts for the lifetime and total cycles (charging fully to empty). 

Recycling Solar Batteries

In general, when it comes to batteries, regardless of size, there is a way to recycle the components. In fact, most areas have their own designated recycling facility. Options range from waste management facilities and recycling plants to a designated storefront with a licensed decommissioning professional.

There are a few different types of batteries on the market, all of which are recyclable! Some types of batteries may be more difficult to recycle than others, nonetheless, recycling attempts are made. Examples of different types of batteries can be found below:

Lithium-Ion Batteries

Nickel-Cadmium Batteries

  • Metals and cadmium are recycled and repurposed
  • Cadmium can be reused for other batteries
  • Long lasting

Lead-Acid Batteries

  • The most common type of battery
  • Easily recycled
  • 90-98% of batteries recycled are lead acid
  • Reliable
  • Long lasting
Although many of the battery options are considered long lasting, the lithium-ion batteries are becoming the more popular battery option for solar installations. Lithium-ion batteries are more affordable, lighter weight, and smaller in size. For these reasons, they are more appealing to homeowners and are the most efficient for their size.


The best way to recycle solar batteries is either through a licensed professional or by returning the battery to the manufacturer. When making the decision to install a battery backup system, make sure you ask your solar battery installer or provider about the different types of batteries and their recycling options.
