A hanger bolt typically consists of two parts: a threaded screw-like end and a lag bolt-like end. The threaded end is used to penetrate and secure the solar panel mounting structure, such as wooden or metal racking systems. The lag bolt end is used to anchor the hanger bolt to the surface, such as a roof or the ground. The installation process involves drilling a pilot hole into the mounting structure, inserting the hanger bolt into the hole, and then tightening it using appropriate tools. The threaded end provides a secure connection, while the lag bolt end ensures stability and prevents the hanger bolt from pulling out under the weight and environmental forces acting on the solar panels. Hanger bolts are often made of durable materials, such as stainless steel or galvanized steel, to withstand outdoor conditions and provide long-term stability. They are available in various lengths and diameters to accommodate different mounting systems and installation requirements. It's important to note that while hanger bolts are commonly used in solar panel installations, the specific requirements and recommended hardware may vary depending on the manufacturer, mounting system, and local building codes. Therefore, it's always advisable to consult the manufacturer's guidelines or seek professional assistance to ensure proper installation and compliance with relevant regulations.
