4 FAQs about Understanding Solar Panels

Why are solar panels important?

Solar panels are the most important part of a solar power system since they produce the electricity that eventually finds it's way to your laptop, lights and television. In this basic introduction, we look at how this happens. How do solar panels work? Solar panels convert sunlight into electricity through a process called the photovoltaic effect.

How do solar panels work?

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.

What are solar panels?

Solar panels are devices designed to absorb sunlight and convert it into usable electricity. They are a cornerstone of solar energy systems and can be found on rooftops, in solar farms, and at other installations around the world.

What are the basics of solar energy technology?

Learn the basics of solar energy technology including solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.
