Fix the purlins of photovoltaic panels
These issues are mainly because of faulty practices followed at the time of designing and installation of the solar plant. The reason may involve the ignorance of EPCs involved or wrong considerations taken during the designing level. Some of these issues are discussed below: 1. Variable structural tilt At another site in.
1. No scope of expansion to the modules One of the unique issues was found in a plant in Rajasthan where the EPC did not provide scope for expansion to the modules. As a result, the frame of the modules started bulging.
1. Designing:At the time of designing, standards, wind zone, wind speed assumptions must be taken with consideration. Appropriate assumptions must be taken while simulations so you are able to draw beneficial.Purlin should be rigidly connected to the torque tube such that the torque tube can achieve rigid rotation of the Purlins and eventually the panels. We observed that the connection was badly articulated and has resulted in tearing and enlargement of the purlin hole, thus resulting in a “wobble” of the purlin on the tube.

Faulty connection of purlin leads to damage of PV panels. Fig. 10 represents the torque tube solar PV MMS and their purlin connections [13] . Download: Download high-res image (404KB).
Purlins: Secondary solar Structure Components called purlins hold the solar panels in place and connect the rafters. Sizing purlins involves figuring out their span, section characteristics, and load-carrying capability, much like rafters. Purlins support the array’s structural stability by uniformly distributing the panel weight over the .
PV panels are mounted on U-purlins which are in turn supported on existing building roof purlins. Roof top solar panel installation adds some dead load due to weight of panels and mounting systems. Once the size of the solar panel is fixed, the existing structure must be evaluated for added solar panel loads.
When mounting on corrugated and sandwich roofs, you fix the photovoltaic installation directly to the purlins of the roof construction. For wooden purlins, you need the stock screw set for wood and for steel purlins the stock screw set for steel.
