Let’s break down the process of how solar PV energy works in a simple, step-by-step way: Sunlight Hits the Solar Panels: The process begins when sunlight reaches the solar panels installed on a roof or a solar farm. These panels are made up of smaller units called solar cells, typically composed of semiconducting materials like silicon.
Solar panels are a remarkable technology that converts sunlight into electricity, providing a clean and renewable source of energy. Understanding the science behind this conversion process involves delving into the physics of photovoltaic (PV) cells, which are the fundamental components of solar panels.
It all boils down to the photovoltaic effect (PV), a fascinating process that enables us to convert sunlight into usable electricity with affordable, readily-available technology. Let’s take a closer look at the science behind it and why it’s so essential in our quest for a cleaner, greener future.
As we've explained, the solar cells that make up each solar panel do most of the heavy lifting. Through the photovoltaic effect, your solar panels produce a one-directional electrical current, called direct current (DC) electricity. Your home can't use DC electricity directly—it needs to be converted to alternating current (AC) electricity first.
Bifacial solar panels can capture sunlight from both sides, increasing the amount of electricity generated. These panels are particularly effective in environments with reflective surfaces, such as snow or white roofing, which can bounce additional sunlight onto the rear side of the panels (Energy.gov).
Photovoltaic research is more than just making a high-efficiency, low-cost solar cell. Homeowners and businesses must be confident that the solar panels they install will not degrade in performance and will continue to reliably generate electricity for many years.
