Solar PV Systems
When sunlight hits solar cells, electrons are shaken free and move around. Electrons are the negatively charged particles that sit around the nucleus of an atom (the nucleus consists of protons and neutrons). An electric current is simply the movement or flow of electrons in the same direction. A bolt of lightning, for example, is a sudden surge of electrons across a build-up of charge within clouds, or between clouds and the ground.
If you place a group of these PV cells together in a panel, and install a number of panels side by side, you can create a flow of electrons and DC electricity. The electricity used in households, however, is AC 240 volts. Therefore a box called a solar inverter – usually no bigger than your average shopping basket – is used to convert the DC electricity to AC so it can be used immediately by occupants and the electricity grid.
