How do solar panels work? Solar power explained
At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect."
A photovoltaic system consists of one or more solar panels, an inverter that converts direct current electricity to alternating current electricity, and sometimes other components such as controllers, meters, and trackers. Most panels are in solar farms or rooftop solar panels which supply the electricity grid.
For homeowners ready to make the switch, residential solar panel installations have become more accessible and cost-effective than ever before. A solar panel system, also known as a photovoltaic (PV) system, converts sunlight directly into electricity through a process called the photovoltaic effect.
Solar panel technology is undergoing a rapid, disruptive evolution, pushing boundaries in efficiency, materials, and integration. Improvements in cell performance, the use of novel materials like perovskites, and flexible, adaptable designs are fundamentally transforming how solar energy is generated and deployed.
The newest solar panel technology includes perovskite silicon tandem cells, transparent PV glass, and ultralight flexible solar sheets. These technologies aim to increase efficiency while expanding where solar panels can be installed. What are the most efficient solar panels in 2026?

A solar panel is a device that converts sunlight into electricity by using multiple solar modules that consist of photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons
To boost the power output of PV cells, they are connected together in chains to form larger units known as modules or panels. Modules can be used individually, or several can be connected to form arrays.
