Here is a step-by-step breakdown of what happens with a DC-coupled system: Sunlight hits the solar panels and the energy is converted to DC electricity. The electricity enters the battery and is stored as DC electricity. The DC electricity then leaves the battery and enters an inverter to be converted into AC electricity the home can use.

When the EROI of a source of energy is less than or equal to one, that energy source becomes a net "energy sink", and can no longer be used as a source of energy. A related measure, called energy stored on energy invested (ESOEI), is used to analyse storage systems.[3][4] To be considered viable as a prominent fuel or energy source a fuel or ...
A photovoltaic (PV) panel, commonly called a solar panel, contains PV cells that absorb the sun''s light and convert solar energy into electricity.
