Who does the solar power store energy for use later?

The only way that you can store power from your solar system now is through the usage of some style of batteries. The premise is that you use the power from the solar panels on your property and this is used for all your loads. If your system is still producing more power than you can use in your house then the extra power can be redirected into a storage device / battery. The inverter with require a battery charger component and metering to know when to charge the system and at what frequency and amounts. Once your batteries have enough charge and the meters installed note that your solar system is now not producing enough power to supply all your loads in the property then is will start to discharge your battery o help cover the usage.
