How Long Do Pylontech Solar Batteries Really Last?

Buying solar system components is relatively expensive. You save up for a long time and sometimes you even have to get a loan. But, where can you get a loan for solar equipment in South Africa? Well, there are a few places, one that comes to mind quickly is GREENFIN.  It can not be argued that investing in solar requires a bit of saving. When a lot of people are doing their research they always wonder if spending all that money buying solar equipment is worth it. It actually is worth it in the long run. So because installing solar in your home is capital intensive, it only makes sense that you want the solar batteries to last. 

EnergySage says that the general range for a solar battery's useful lifespan is between 5 and 15 years. If you install a solar battery today, you will likely need to replace it at least once to match the 25 to 30 year lifespan of your PV system. However, just as the lifespan of solar panels has increased significantly in the past decade, it is expected that solar batteries will follow suit as the market for energy storage solutions grows.

5 Things You Must Know Before Going Off-Grid In South Africa

Proper maintenance can also have a significant effect on your solar battery's lifespan. Solar batteries are significantly impacted by temperature, so protecting your battery from freezing or sweltering temperatures can increase its useful life. When a PV battery drops below 30° F, it will require more voltage to reach maximum charge; when that same battery rises above the 90° F threshold, it will become overheated and require a reduction in charge. To solve this problem, many leading battery manufacturers, like Tesla, provide temperature moderation as a feature. However, if the battery that you buy does not, you will need to consider other solutions like earth-sheltered enclosures. Quality maintenance efforts can definitely impact how long your solar battery will last.

Thanks for answering this question so nicely. The bigger the cash injection the longer the life span. That`s my motto.

Interesting to know. Can you please touch a little bit more on how to maintain solar batteries. Is this something a person can do at home on their own?

@Blessing I strongly don’t think sir. Batteries in general are things you should never buy secondhand. You don’t want the stress of it.

What are these “Quality maintenance efforts” for solar batteries? I’d love to know how to. Maybe we can do this as a task during lockdown 😂

Is it ever a good idea to buy second hand solar batteries? Cost in mind.

I have spent so much money on solar equipment. It is worth every single cent because when load shedding happens… I am never in the dark! i say go for it.

I would if i could. But i don`t own my own home. I am renting and i don`t think my landlord would appreciate that at all

Make sure that all the components are compatible before you rig your system.

I hear tesla is the gold standard of solar batteries. 20 year lifespans

I agree with Nigel. Always trickle charge. That way your solar battery charges at the same pace as it decharges.

To use solar batteries for longer don’t use them until flooding.

Always trickle charge! Trust me.

Don`t put solar batteries in very humid conditions

If your solar system was wired correctly by a professional i think even 10 years is possible

I think if is all about how well you look after your batteries. Avoid incorrect connections
