Many enthusiasts and potential buyers of solar energy often ponder whether solar panels require direct sunlight. The straightforward answer is yes. Solar photovoltaic (PV) systems depend on solar radiation to produce electricity, so any obstruction blocking the incoming solar rays will lead to a reduction in the amount of electricity generated by the panels. Additionally, shade has a significant impact on solar panels because it prevents direct sunlight from reaching them.
Another factor that affects solar panel efficiency is temperature fluctuations. Contrary to what some might expect, rising temperatures do not necessarily boost the panel's performance. In fact, excessive heat can reduce the panel's output by about 10-25 percent. Specifically, for every degree Celsius above 25°C, the maximum efficiency of a panel can drop by approximately 0.38 percent. Users can check the panel's heat tolerance by referring to the manufacturer's datasheet. Shading, however, does not provide a solution to overheating issues.
Shading can severely impact solar panel efficiency. Typically, solar panels operate at only half their efficiency when partially shaded. Solar PV systems consist of multiple panels arranged in arrays to meet the electrical demands of each panel. Each array comprises numerous solar PV cells, which are the fundamental components that absorb solar energy and convert it into direct current (DC). These panels are often connected to inverters that convert DC into alternating current (AC) to power household appliances or supply the grid. Panels are typically divided into strings based on the voltage requirements of the inverter. Smaller systems might have just one string, whereas larger ones could have several. You can think of these strings as conduits for solar energy. When shading occurs, the flow of energy becomes obstructed. If even one panel is shaded, the entire string's output can plummet to zero.
To avoid energy losses caused by shading, there are strategies you can employ. Shading can result from various sources such as clouds, fog, trees, or even chimneys. Although complete avoidance of shading may not always be feasible, there are ways to minimize its impact. Utilizing a string inverter equipped with Maximum Power Point (MPP) tracking capability enables the inverter to extract the maximum possible output from a series of solar panels. This MPP tracker reduces power loss due to partial shading and other issues affecting panel output. Similarly, power optimizers and microinverters can be beneficial if the shading on your roof is limited. These systems allow each panel to function independently, ensuring that the overall system performance isn't excessively affected by one or two shaded panels.
These measures are effective only when dealing with partial shading. It’s better to prevent shading issues during the installation process itself. Selecting the appropriate solar panels and ensuring an unobstructed installation area are among the best approaches to tackle shading-related problems.
