Solar batteries enable you to store surplus energy when your solar panels produce more electricity than you need. This stored energy can then be used during times of lower solar generation, such as nighttime or cloudy days. By using stored energy, you draw less power from the grid, leading to reduced reliance on utility-supplied electricity and ultimately lower energy bills.
Solar batteries play a crucial role in optimising your solar energy system. They allow you to store excess energy generated by your solar panels during the day and use it during the evenings or cloudy periods. This means you can rely less on the grid, increase self-consumption of solar energy, and enhance your overall energy independence.
Solar batteries, also known as solar energy storage systems, are typically made using a combination of materials, including lithium-ion (Li-ion) or lead-acid battery technologies. Lithium-ion batteries are commonly used due to their high energy density, long cycle life, and efficiency. These batteries consist of various components, such as electrodes, electrolytes, and separators, all encased in a protective casing.
The size of a solar battery depends on the type of battery being installed. The latest, sleek DC batteries installed as part of your solar installation are 490 x 90 x 675mm per 5kWh of storage (You can combine as much as 15 batteries together). These can be fixed to the wall next to eachother, or stacked on the floor.AC batteries which complement existing solar arrays are larger in size and come in two capacities 5kWh (550 x 1460 x 165 mm) and 10kWh (860 x 1460 x 165 mm).
Yes, energy storage has been a part of many grids since the 1930s. Lithium-Ion technology remains the most cost-effective and popular option for homes owing to its safety, reliability, performance levels and price when compared to other battery technologies.
