Battery storage is a technology that allows energy to be stored for later use. In residential and commercial applications, battery storage can be used to store excess energy generated by solar PV systems during the day, which can then be used at night or during periods of high energy demand. This means that homeowners and businesses can reduce their reliance on the grid and save money on their energy bills, while also reducing their carbon footprint. Battery storage can also provide backup power in the event of a power outage, ensuring that critical systems and appliances remain operational. With advances in technology, battery storage systems are becoming increasingly efficient and affordable, making them an increasingly popular choice for consumers looking to switch to a more sustainable energy source.
