Wind Loads
Verified by SOLBE Structural Engineering Board
Definition
Wind loads are the dynamic structural forces exerted by moving air currents on a solar array and its mounting framework, representing the most critical factor in structural stability engineering.
Technical & Structural Breakdown
Dynamic wind load calculations determine the wind pressure acting on a solar panel surface. Under IS 875 Part 3 (Indian Standard code), design wind speed (Vz) is computed using the basic wind speed of the location (ranging from 33m/s to 50m/s in India) modified by factors for height (k1), terrain (k2), topography (k3), and cyclone probability (k4). The resulting pressure translates into severe uplift or downward forces, which dictate foundation weights, anchor counts, and structure thickness.
