Solar panels do not need direct sunlight to work, and they can use direct or indirect sunlight that produces electricity in cloudy, shade, rain, and snow. The increasing demand for renewable energy sources has led to the growing popularity of solar power. Solar-powered electricity generation has evolved into one of the viable solutions for both homeowners and businesses. However, there still exist misconceptions regarding the operational mechanisms and optimal conditions required for solar panels to function effectively.
Solar panels convert sunlight into electrical energy and store it in batteries for future use. There are two distinct types of solar panels, namely monocrystalline and polycrystalline, differing primarily in terms of their efficiency levels. So, solar panels work best in direct sunlight. Your solar panels should receive at least four hours of direct sunlight per day. However, in many cases, solar panels may not get direct sunlight. They may be covered in shadow or affected by weather conditions like cloudy, rain, or snow. Solar panels can also work without direct sunlight. Although, they do not work at 100 percent capacity.
Adjustment Solar Panels Angle
Solar panels produce energy with solar cells. To maximize power, it needs to be well-oriented. This is because the more direct sunlight a solar panel receives, the more power it will produce. The amount of power a solar panel depends directly on how much sunlight is accessing it. This sunlight is generally the sum of direct, diffuse, and reflected sunlight.
The solar panel that is directly facing the sun utilizes both direct and indirect sunlight, thereby maximizing its power output. The solar panel receives indirect sunlight, resulting in a power generation of 20% of its rated capacity. Hence, it is crucial to adjust the orientation of your solar panel(s).
Solar Panels in Weather Conditions without Direct Sunlight
Weather conditions can have a big impact on solar panel production. Clouds, rain, and snow can reduce both direct and indirect sunlight, hampering solar power production. If there is no direct sunlight available, solar panels will produce electricity using indirect sunlight.
Solar Panels on Cloudy Days
Even when there are dark clouds in the sky, the solar panel still works. The panels harness more than just visible light. The sun emits radiation of different wavelengths, some of which are imperceptible to the human eye. This invisible radiation penetrates the clouds directly into the photovoltaic modules. As long as it is daytime, the solar panels will continue to produce energy. So, if you can’t install solar panels in direct sunlight, they will still work, just at a lower capacity.
Solar Panels on Rain Days
Rain days do not affect solar panel output, but the cloud cover that accompanies rain does. On rainy days, solar panels can produce 20 percent of their optimal capacity. The exact amount value depends on rainfall and cloud cover. But rain helps to clean the solar panels. It can wash away the dirt and dust covering the solar panels.
Solar Panels on Snow Days
Solar panels can also work in snowy conditions. It can block the panels from receiving sunlight. But sunlight can pass through a light dusting of snow. In addition, snow usually melts off quickly. On the other hand, similar to rain, snow helps to clean the solar panels as it melts away.
Solar Panels Work in the Shade
Solar panels can work in the shade. Those panels are composed of solar cells, and if those cells are covered by shade, they will not function 100%. The longer a solar panel is in the shade, the more its efficiency drops. However, the path of the sun’s rays changes, and sunlight and shadows will change over time. In addition, you can also adjust the angle of the solar panels according to the lights.
Solar power is a 100% green, renewable, and stable source. Solar panels are a valuable source of solar power. While solar panels work best in direct sunlight, they still work in cloudy, shade, rain, and snow.
