With Energy Matters, you can be sure you’re getting the best possible deal on solar energy. If a lithium ion solar battery catches fire, it will burn ferociously and can release nasty gases, which may include phosphorus pentafluoride, phosphoryl fluoride and hydrofluoric acid vapours. There are two measurements to consider: Storage capacity is how much energy the battery can hold; usable capacity is the energy the battery can provide minus the energy needed to operate the battery. Lithium ion batteries have a high depth of discharge, meaning if the battery capacity drops to 10%, it won’t strain the system or cause the system to degrade.

Solar Batteries: What you need to know about backup power

I’ll guess from year eleven onwards, the annual drop will be higher. The age of the solar panels might factor into this benefit. With batteries, the power rating specifies how much power the battery can deliver.
