Solar panel

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

What are the components of a PV system?

A photovoltaic system is a set of elements that have the purpose of producing electricity from solar energy. It is a type of renewable energy that captures and processes solar radiation through PV panels. The different parts of a PV system vary slightly depending on whether they are grid-connected photovoltaic facilities or off-grid systems.

Types of PV Systems

These types of systems may be powered by a PV array only, or may use wind, an engine-generator or utility power as an auxiliary power source in what is called a PV-hybrid system. The simplest type of stand-alone PV system is a direct-coupled system, where the DC output of a PV module or array is directly connected to a DC load (Figure 1).

In AC-coupled systems, the solar energy needs to be inverted (changed from AC to DC, or vice versa) multiple times before it''s discharged from your battery into your home. Each time electricity is inverted, a little bit is lost in the process, making for a less efficient system. As such, AC-coupled systems typically have round-trip efficiency
