Solar panels are made of photovoltaic cells (that is why generating electricity with solar panels is also called solar PV) that convert the sun’s energy into electricity.
Photovoltaic cells are sandwiched between layers of semiconducting materials such as silicone. Each layer has different electronic properties that energize when hit by photons (tiny particles packed with energy) from sunlight, creating an electric field. This is known as the photoelectric effect – which generates the current needed to produce electricity.
They generate a direct current of electricity. Then it passes through an inverter to convert it into an alternating current, which can be used by the home or business attached with these panels.
Do solar panels work on cloudy days?
They react to the visible light spectrum, which means if there is enough light to see, solar energy is enough for them to generate electricity. The stronger the sunlight results, the better outcomes.
Does it need to be hot for solar panels to work?
They produce more electricity in summer, which seems like they need warmer weather to work. But this isn’t the case – it’s just that stronger sunlight and warmer temperatures often go hand in hand. If the temperature gets too hot (or too cold), solar panels become less efficient.
