Solar-powered batteries 101: All you need to know

In an era where the world is moving towards more and more sources of sustainable energy, an often overlooked source, as well as medium of energy, happens to be solar power.

More specifically, solar-powered batteries. Here’s all you need to know about these nifty little devices – how they work, and why you should give them a whirl.

What solar-powered batteries are and how they work

Solar panels are known to be able to save households thousands of rupees every year in electricity bills. However, they do have certain limitations. The fact is, for them to be able to absorb and generate energy, they’re dependent on sunlight. Moreover, they aren’t entirely viable as a backup during power cuts, owing to their variable output.

Well, this is where solar-powered batteries step in. Solar-powered batteries, in essence, store excess solar energy absorbed by your home’s solar panels, for use when you need it. This energy is stored in a chemical form, and is converted into electricity as and when required.

What’s cool is, when there is a lack of sunlight, etc., they can also be recharged from other sources of electricity, including your grid’s power supply. Wind turbines, or any other source for that matter.

Which appliances can solar powered batteries power?

While they may not be capable of powering your entire home together, Solar-powered batteries can run a select few appliances during large-scale power outages, including small refrigerators, your Wi-Fi router, or a few lights and power outlets. Moreover, should you happen to have multiple solar-powered batteries, they can even power water pumps or air conditioners in your home.

What’s more, if your local electricity board charges higher rates during certain hours, you can avoid those charges by switching to a solar-powered battery as and when possible.

Things to keep in mind when selecting a solar-powered battery for your home

There are two main considerations to keep in mind when purchasing a solar-powered battery for your home.

1. Energy storage capacity 

The energy storage capacity (kilowatt hours or kWh) of a solar-powered battery refers to the maximum amount of power it can actually store when filled to capacity.

2. Rated power output

The rated power output (kilowatts or kW) of a solar-powered battery tells you the total electrical load you can connect to a battery at any given point in time.

Why you should consider investing in a solar-powered battery

Solar-powered batteries, along with solar panels, are slightly expensive to purchase and set up, as compared to normal grid electricity. However, the savings they ensure for you in the long run are significant. Moreover, the fact that they work on a virtually inexhaustible, renewable source of energy also makes them much more ecologically friendly, as compared to the use of grid electricity or even fossil fuels.

So do your bit for the enviroment, and give solar-powered batteries a whirl!
