Solar energy used for electricity is called solar electric or photovoltaic (PV).
Photovoltaic panels consist of photovoltaic cells that convert sunlight to electricity throughout the day. They do so by absorbing photons of light and converting those into electrons, which produces a direct current (DC) power.
Because all of our appliances use alternating current (AC) electricity, the electricity must be converted from DC to AC through a critical piece of equipment called an inverter.
