Answer :
The statement that solar panels (photovoltaic cells) still work when the panel is shaded is false. The solar panel needs direct sunlight in order to produce electricity. However, modern solar panels work even in poor light conditions. Shade reduces the effectiveness of solar panels, which means that less electricity is produced.
Solar photovoltaic (PV) cells can generate electricity even when shaded or during cloudy conditions, operating at 10-50% capacity. This is due to the fact that daylight contains photons essential for electricity production. Solar PV systems are thus reliable and can be paired with energy storage technologies to enhance efficiency.
Solar photovoltaic (PV) cells are devices designed to convert sunlight directly into electricity using semiconducting materials like silicon. Despite common misconceptions, PV cells can still generate power when not directly exposed to sunlight. Under cloudy conditions, solar panels can operate at 10-50% of their full capacity, depending on the density of the clouds because daylight still contains photons, which are necessary for the production of electricity in PV systems.
Unlike solar thermal systems, which require direct sunlight to function effectively, PV panels do not need bright, unobscured sunlight to generate electricity. Consequently, even when there's no discernible shadow—indicating the absence of direct sunlight—PV panels can still harness the diffuse light available to produce a meaningful amount of electricity. This makes solar PV cells particularly versatile in various lighting conditions.
It is important to note that maximizing energy production from solar cells typically means ensuring they are exposed to as much direct sunlight as possible. However, technologies such as energy storage systems are often paired with solar PV installations to compensate for times when sunlight is insufficient. This underpins the durability and reliability of solar PV systems, especially when utilized in areas with variable weather conditions.
