Utility-scale and large commercial ground- mounted solar systems are becoming more common in Western Canada. One of the challenges solar projects developers are facing is the unknown of the ground conditions, resulting in the uncertainty in the foundation design and overall project costs. Let us walk you through what a proper testing program for a …
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
