Solar Photovoltaic (PV) System 101: Understanding the Main Components

Due to the constant increase in the cost of electricity, you might be considering an alternative source of energy to partially or even fully cover your home electricity bill. To help you understand the basics, let’s take a look at the main components of a solar PV system.

 

1.Solar photovoltaic (PV) panels

 

Solar photovoltaic (PV) modules, also known as solar panels, are devices that convert sunlight into electricity. They consist of several smaller pieces known as solar cells. When sunlight hits these cells, it drives the electrons, resulting in an electric current.

 

PV modules are essential components of solar PV systems, producing a clean and renewable source of electricity for homes, companies, and various other applications.

 

2. Inverter

 

Solar inverters take the DC electricity from the solar PV array (i.e., multiple solar panels wired together) and use that to create grid-compatible Alternating Current (AC), which is what powers everything in your home.

 

Inverters are specified to maximize the PV output from the PV array while minimizing power losses. Solar inverters are sized and chosen taking into account the power capability of each solar panel, the operating temperatures, and the number of solar panels in each string (voltages).


3. Batteries

 

Solar PV systems produce electricity during the day when there is sunlight. Batteries are used to store energy generated during the day to be used throughout the night or on cloudy days when the system is no longer generating power.

 

The battery setup is sized using the size of the load requirement and autonomy. Autonomy is the number of days the system will work without electricity generation from solar. The generally recommended autonomy days are 2-5 days. 

 

Lithium Iron Phosphate (LiFePO4) is a type of rechargeable battery commonly used in solar photovoltaic (PV) systems for energy storage. It is known for its high energy density, long cycle life, and enhanced safety characteristics. LiFePO4 batteries are well-suited for solar applications due to their ability to efficiently store and discharge energy, making them an ideal choice for off-grid or hybrid solar PV systems where reliable energy storage is essential.

 

The specific solar PV system for your home or office will depend on different factors, including the physical location and size of the build for panel installation, the amount of solar irradiance at your building, your load requirement (the equipment that you need to power), and your budget.

To determine a suitable solar PV system for your site, you will need an expert to conduct a site and load requirement survey before settling on a system.
