The process begins when sunlight penetrates the protective glass layer of the panel. The angle and orientation of the panels determine how directly they face the sun throughout the day.
How Solar Cells Convert Sunlight into Electricity
This critical translation is the sole responsibility of the inverter, a small box often mounted near the electrical panel. Inside these cells, the photovoltaic effect occurs as described above, generating DC electricity.
The magic lies in the internal electric field, created by combining two types of silicon—n-type and p-type—to form a p-n junction. Additionally, temperature plays a role; while solar panels thrive in cold, sunny conditions, they lose efficiency as they heat up on extremely hot afternoons.
How Solar Cells Convert Sunlight into Electricity
When production exceeds consumption, the surplus is often fed back to the grid through net metering, effectively spinning the meter backward and accumulating credits for later use during nighttime or cloudy days. The electricity generated by the system can be used immediately to power loads in the house, reducing reliance on grid power.
