Technical FAQs 4

How much kWh should a battery energy storage system store?

“I just want to store electricity for my house” you’re probably thinking, and while the impressive functionality of Battery Energy Storage Systems does just that, factors like kWh do play an important role. Specifically, if you’re a homeowner, you’re probably looking at anything from around 5kWh to 10kWh to meet your needs.

Should I add more solar panels or batteries to my home energy system?

To understand whether it’s better to add more solar panels or batteries to your home energy system, it’s a good idea to know exactly how these devices work individually and together. Solar panels convert sunlight into electricity, which can be used to power your home directly.

Do I need more solar panels?

Larger homes and those that use higher amounts of energy, would need more panels. Compatibility issues – Adding more panels to an existing system may not be straightforward, especially if the system is older or incompatible with newer systems.

Why should you choose a solar panel for your home?

Limited roof space – The number of panels that can be added may be restricted by the available roof space. Increased energy storage – More batteries means you can store more energy. This means you can run your home for longer periods of time just from the battery. If paired with solar panels, this is the cheapest electricity you can get.
