Most modern solar panels feature pre-drilled holes in their aluminum frames. These pre-drilled holes are designed to simplify the installation process and ensure the panels can be securely fastened to mounting structures. These holes are typically located along the aluminum frame that surrounds the photovoltaic cells, providing structural integrity while. . And here's where a common question pops up: do solar panels come with mounting holes in the back, or do you have to drill your own? Let's clear that up next.
