You can use the energy you get from the solar panels anywhere. The only problem is that you need an additional device to store energy and transmit it if necessary. I also have solar panels, and to energize my house, I bought an inverter herehttps://sbpe.com.au/collections/victron . It is a good inverter that converts direct current to alternating current. It is thanks to the inverter in my house there is always electricity. Thanks to the panels, I save a lot of money.
