How do solar panels create a usable electricity system?
Here's how solar arrays create a usable electricity system for your home: 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.
What are photovoltaic (PV) solar cells?
In this article, we'll look at photovoltaic (PV) solar cells, or solar cells, which are electronic devices that generate electricity when exposed to photons or particles of light. This conversion is called the photovoltaic effect. We'll explain the science of silicon solar cells, which comprise most solar panels.
Can thin-film solar panels replace fossil fuels?
However, companies like First Solar have built entire businesses on producing panels with thin-film solar cells (in their instance, CdTe cells) for primarily large-scale utility power stations that aim to replace fossil fuel energy sources.
What happens if solar panels produce more electricity than you use?
If your solar panels produce more electricity than you use, your utility may credit you for the excess power generated, which is sent back to the grid—this is known as net metering. Your electric bill will thus reflect the net amount of electricity you consume minus what your solar panels generate. Need solar panels for your commercial property?
