The Role of Skill in Solar battery system

Reliable power when you need it most

Solar batteries store excess solar energy generated by solar panels to be used when the solar system isn’t producing energy or during a power outage to keep key appliances running. However you should take into account whether you are on a tariff which has different electricity costs depending on the time of day time of use, or TOU tariff and, if you generate your own electricity, how much of this you use already. The nominal capacity is the total amount of energy the battery can hold, while the usable capacity is how much of that can actually be used, after the depth of discharge is factored in. There are only a handful of companies making this battery today, the most notable being Redflow, an Australian company. Plus, you won’t be left in the lurch during a power outage because batteries can continue to supply stored energy with blackout protection. Energy storage can be useful if you generate renewable electricity and want to use more of it, or outside of daylight hours. The home battery storage system can then be discharged in the evening to reduce the amount of power the homeowner needs to buy from the grid.
