How is Solar Energy Produced in 2020? | EnergySage
Electricity generated by loose silicon electrons is DC electricity and needs to be converted to AC electricity for before we can use it. This conversion is done by important devices called inverters. Inverters can be configured as string inverters, microinverters, or power optimizers , but each setup performs the same general function of turning DC electricity to AC electricity.

Why Do Ionic Compounds Conduct Electricity in Water? …
In their bonded, solid states, molecules like salt don’t conduct electricity. But when they''re dissociated in a solution or through melting, they can carry a current. This is because electrons can’t move freely through water (in the same way they do in a conductive wire), but ions can move freely.

Ionic and Metallic Bonding
In contrast with ionic bonding, the valence orbitals are delocalized over the entire metal lattice, electrons are free to move and are not associated with individual ions. The ''free valence electrons'' model explains several properties of metals: they conduct electricity, are malleable and ductile (can have their shape changed without breaking) and are not volatile.
