At the heart of a solar panel’s operation is the photovoltaic effect. This effect was discovered in the 19th century and forms the foundation of modern solar technology. It’s the process by which sunlight is converted into electricity. Here’s how it works:

1. Absorption of Sunlight: Solar panels are made up of many small units called solar cells or photovoltaic cells. These cells are typically made of silicon. When sunlight (photons) strikes these cells, they are absorbed.
2. Electron Excitation: As photons from the sunlight are absorbed by the silicon in the solar cell, they impart energy to electrons in the material. This energy boost allows the electrons to escape from their normal positions within the atoms of the silicon.
3. Generation of Electric Current: The movement of these energized, or “excited,” electrons creates an electric current. This flow of electrons is what we harness as electricity.
4. Electricity Conversion: The solar panel’s structure and electrical connections collect the generated electricity, which is then made available for use in homes, businesses, or the grid.

The Role of Inverters

While solar panels are responsible for generating direct current (DC) electricity, most of our electrical devices run on alternating current (AC). This is where inverters come into play:

1. Conversion to AC: Inverters are devices that convert the DC electricity produced by solar panels into the AC electricity used in our homes and businesses.
2. Grid Interaction: In grid-connected systems, excess electricity can be sent back to the grid through the inverter, allowing you to earn credits or even receive payment from your utility company—a process known as net metering.

Solar Panels in Action

Now that we understand the fundamentals let’s see how solar panels operate in a practical sense:

1. Sunlight Absorption: Solar panels are strategically placed on rooftops or ground-mounted arrays, ideally facing south to capture the maximum sunlight.
2. Energy Generation: When sunlight hits the solar panels, the photovoltaic cells in each panel convert the energy into DC electricity. The more panels you have, the more electricity you can produce.
3. Inverter Conversion: The DC electricity is sent to an inverter, where it’s converted into AC electricity, ready for use in your home.
4. Electricity Consumption: The AC electricity is then distributed throughout your home, powering your lights, appliances, and other electrical devices.
5. Excess Electricity: Any excess electricity produced but not consumed is typically sent back to the grid through your meter. This excess electricity can be credited or compensated by your utility company.
