how efficient are solar batteries
101 Guide to Solar Batteries
A solar battery''s round-trip efficiency represents the amount of energy that can be used as a percentage of the amount of energy that it took to store it. For example, if you feed 5 kWh of electricity into your battery and can only get 4 kWh of useful electricity back, the battery has 80 percent round-trip efficiency (4 kWh / 5 kWh = 80%).
