A solar energy system comprises several essential components. Before installing a solar energy system at your premises, it is important to understand how each component works. Read this detailed guide to understand the functionality of a solar energy system.

Components of A Solar System

  • Solar panels, inverters, racking, and battery are the four essential components of a solar energy system. Read on to understand their working in detail.

Solar Panels

  • Also known as photovoltaic panels, solar panels are the backbone of any solar system. Solar panels work on the photovoltaic effect and convert sunlight into electrical energy.

Multiple solar cells are combined to make a solar panel, and a combination of several solar panels makes up one solar system. This is known as a solar array. Solar panels can either be installed on the rooftops of buildings or mounted on the ground.


  • Solar panels are inclined at specific angles to allow optimal absorption of sunlight throughout the day. When the panels absorb solar irradiations, DC (direct current) electricity is generated because of the movement of electrons through the built-in solar cells of the solar panel. The material of the solar panel should be chosen carefully as overheated panels become less efficient.

Solar Batteries

  • The energy generated throughout the day can be stored for use during the night with the help of batteries. A battery is not necessary for the grid-tied solar system. This system can draw energy from the electricity grid in the evening. If you have an off-grid system, you will need a solar battery for using power during the evening.

Hybrid System

  • You can use more than one battery depending on your energy usage. In instances where the solar system generates a large amount of energy, a battery can store this excess energy for later use. This type of setup is referred to as a hybrid system.

Solar Inverter

  • Another essential component of a solar system is a solar inverter. The purpose of a solar inverter is to convert the DC electricity produced by the solar panels into AC (Alternating Current) electricity. This 240V AC electricity is responsible for powering everything in your home. The inverter is a key component of a solar system that works consistently throughout the lifespan of your solar system.

The inverter comes with a warranty of about ten years whereas, solar panels can last as long as 25 years or longer. Since an inverter has to work constantly to generate AC electricity, you must choose a high-quality brand.

Types of Inverters

There are two main types of inverters. These include:

String Inverter

  • As the name indicates, a string inverter converts the energy from a string of panels into AC electricity. These are installed in a shady area.


  • Micro inverters allow the energy from panels to exist independently thereby allowing the panels to work separately. These are present on the back of each solar panel.

Racks and Mounts

  • key components of a solar systemAlthough racks and mounts are not electrical components of a solar system, they are essential for the efficient working of a solar system. They are required for firmly attaching solar panels to the roof.

The quality of racking is a critical factor to consider. In addition, correct installation is also vital. If the panels are mounted at the incorrect angle, the efficiency of a solar system will be compromised.

  • If you have damaged solar panels, faulty inverters, expired electronics, and other faulty hardware, do not throw them away. Instead, opt for specialized recycling and have your solar system components recycled under the regulatory guidelines.
