What are solar batteries?

What are solar batteries?

Batteries for solar panels are devices that store energy generated by solar panels that are part of a photovoltaic installation. They're used to release stored electricity on demand. For example, it can provide you with energy at times when your solar panels aren't producing it.

Solar batteries are a new element of Holaluz's ecosystem of products and services. They complement the virtual battery helping us accelerate the transition to a more sustainable energy model.

Frequently asked questions

Is it worth having a battery for solar panels?

It depends on each home's production and consumption. As a general rule, it might interest people that tend to use most energy at times when their panels aren't producing it (normally at night), or those with a lot of self-consumption surpluses.

What difference is there between a virtual battery and a physical solar battery?

A physical battery for solar panels allows you to store excess energy that your panels produce as and when you need it. A virtual battery , on the other hand, stores your excess energy in the cloud and returns it to you when you need it, whether that’s in kWh or in the form of money. At Holaluz, our virtual battery accumulates money. The energy you don’t use is converted into euros, allowing you to cut down the electricity bill for another property. The best part is, with Holaluz you can have both, because they complement each other perfectly.
