Direct Current

In photovoltaics, only direct current is generated. Photovoltaic modules convert sunlight directly into electrical energy, causing electrons to flow in a specific direction. This directed flow of current is known as direct current.

Characteristics of Direct Current:

• Constant Flow Direction: Unlike alternating current, the flow direction of electrons does not change in direct current.
• Generation: Photovoltaic modules, batteries, and certain types of generators produce direct current.
• Usage:
  • Direct Use: Smaller electrical devices can be powered directly with direct current.
  • Storage: Direct current can be easily stored in batteries.
  • Conversion: To use direct current in the general power grid, it must be converted into alternating current. Inverters are used for this purpose.

Importance for Photovoltaics:

Direct current is the foundation of photovoltaics. The electrical energy generated is always initially in the form of direct current. To make it usable for self-consumption or feeding into the public power grid, various components and processes are necessary.
