What is a Photovoltaic Array

A photovoltaic array, also known as a solar array, is a collection of solar panels that are used to convert sunlight into electricity. These arrays are commonly used in both residential and commercial settings to provide clean, renewable energy.

How Does a Photovoltaic Array Work?

Photovoltaic cells within the solar panels are made of semiconductor materials, such as silicon, that are able to absorb sunlight and convert it into direct current (DC) electricity. When sunlight hits the cells, electrons are released, creating an electric current. This electricity is then sent to an inverter, which converts it into alternating current (AC) electricity that can be used to power homes and businesses.

Types of Photovoltaic Arrays

There are two main types of photovoltaic arrays: flat-plate and concentrator. Flat-plate arrays are the most common and consist of solar panels arranged in a flat plane to capture sunlight. Concentrator arrays use lenses or mirrors to concentrate sunlight onto smaller, high-efficiency solar cells.

Advantages of Using a Photovoltaic Array

One of the main advantages of using a photovoltaic array is the ability to generate clean energy from a renewable source. Solar power produces no greenhouse gas emissions, making it an environmentally friendly choice. Additionally, solar arrays can provide energy independence and reduce electricity bills for homeowners and businesses.

Installation and Maintenance

Installing a photovoltaic array typically requires mounting the solar panels on a roof or in a ground-mounted system. The array must be positioned to maximize exposure to sunlight throughout the year. Once installed, regular maintenance is minimal, with occasional cleaning and inspections to ensure optimal performance.


Photovoltaic arrays are a sustainable and cost-effective way to generate electricity from the sun’s energy. As technology continues to advance, solar power is becoming an increasingly viable option for meeting energy needs in both residential and commercial settings.
