Compared to solar panel systems, batteries are less customizable in terms of size.
Battery storage can be a good financial investment to lower long-term electricity costs at home with greater control over your solar energy use and savings. Storage also provides increased energy security and further carbon emission reduction potential. Are solar batteries safe?
