How Thick Are Solar Panels? Solar Panel Size Explained
Most traditional solar panels measure between 30mm and 40mm (1.18 to 1.57 inches) thick. This thickness is typical for models that use crystalline silicon cells.
Most solar panels are about 1.5 inches thick. The thickness (depth or height) is the only dimension that varies slightly among different solar panel models. The length and width of typical solar panels, along with their wattage and area or square footage, are also important factors to consider.
Solar panel width generally varies between 39.0 inches and 51.3 inches. A common width range of 39.1 to 41.5 inches encompasses many models across different wattages. Wider panels, such as those exceeding 44.5 inches, are often associated with higher wattage models. Depth (or Thickness):
Understanding what contributes to a solar panel's thickness helps buyers evaluate quality and performance expectations. The glass on solar panels plays the biggest role in how thick they are: At Couleenergy, we use special low-iron glass with anti-reflective coatings.
The most common depth is 1.38 inches. Panel dimensions are influenced by wattage, cell technology, and panel design, which means sizes will always vary, even between panels with similar wattage or efficiency ratings. Understanding typical solar panel dimensions can help you plan your solar installation.
