Are lithium-ion batteries a good choice for home energy storage?

Lithium-ion batteries are the most used battery in domestic solar energy systems, and here’s why: Low cost: They have become the most cost-effective solution for home energy storage with the increase in electric vehicle production, bringing the price down by 97% over 30 years.

How much does a lithium ion battery cost?

A lithium-ion battery can cost £3,500 to £6,000 depending on its usable capacity (kWh). On the other hand, lead-acid batteries can only discharge 50% of the total amount of storage which means that they are available at comparatively cheaper prices. A lead-acid battery can cost around £2,000 to £4,500 depending on its usable capacity (kWh).

How much does a solar battery cost in the UK?

Currently, solar battery prices in the UK cost anywhere between £2,500 and £10,000 depending on the battery capacity, type of battery and lifespan. A typical 5 kilowatt hour (kWh) solar battery, suitable for a three-bedroom house, costs £5,000, on average.

How much does it cost to install a solar battery?

The price of installing a solar battery falls by around £2,000-£3,000 if it’s installed at the same time as solar panels. The price of the inverter is already folded into the total amount of a solar panel system installation, and adding a battery doesn’t involve much additional labour cost either.

Is solar battery storage a good investment?

While solar battery storage is optional, it’s a wise investment if you want to be able to store your solar panel’s excess energy once the sun goes down. It’s not a particularly expensive addition to a solar energy system and its inclusion can save you money in the long run and even give you the ability to sell excess energy back to the grid.

How long do lithium ion batteries last?

Low maintenance: Even the most affordable Lithium-ion batteries will last for over 6000 charges when paired with a good battery management system. High battery energy density: They can hold more energy than a lead acid battery. High depth of discharge or efficiency: They can store more energy before they need to recharge.
