These days, many homeowners and business owners are using solar panels as eco-friendly electricity production tools. However, many people view solar energy as a complex concept, and they are unsure of how it works. For a better understanding of this technology, review the guide below. 

What Are Solar Panels Made Of?

Most residential and commercial solar panels are photovoltaic (PV) versions that consist of a collection of solar cells made of silicon. As semiconductors, these cells are constructed with both a positive and a negative layer. Each cell is capable of absorbing sunlight and transforming it into electricity by operating as a battery and creating a clean electric field. 

How Do They Work?

PV solar panels create a direct current (DC) electricity by collecting photons in light and converting them into energy. When the photons contact atoms in a solar cell, they release electrons. An electrical circuit is created when conductors are connected to the cell’s positive and negative sides. As the electrons flow through the circuit, they generate electricity. 

What Are the Different Components?

The panels and solar cells need additional equipment to transfer the generated electricity. For instance, the silicon cells are protected by a highly durable glass casing. Beneath the glass is a layer of insulation, as well as a protective back sheet to keep the panel from overheating, which could reduce its efficiency. Solar panels also have wires that connect the system to a solar inverter. This part converts DC electricity into alternating current electricity, which is what most homes use to power their appliances.
