Step 8 - Place SGM purlins over the rafters according to the given measurements. Step 9 - Insert SGM angle clamps in the edge purlins and SGM T clamps in the middle purlins. 19.
The Clean Energy Council’s (CEC) solar guidelines for residential PV recommend a minimum tilt of 10° to ensure self-cleaning by rainfall; and for grid-connected PV systems, CEC recommends positioning panels at the angle of latitude to maximise the amount of energy produced annually.
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.
The size of different components, such as legs, rafters, purlins, and their corresponding thicknesses, must be carefully considered to ensure the strength and lifetime of solar panel arrays. The main factors and methods for sizing these structural components for solar panel structural design are covered in detail in the next section.

6 FAQs about [How to position the purlins when installing photovoltaic panels]
How to install solar panels?
Once racks are in place, installers have to carefully place solar panels on them while utilizing suitable clamps or mountings. The solar system needs to be wired after mounting equipment’s. Electrical conduit should run from various parts like inverters, disconnects, electrical panels to the solar panels among others.
Should a purlin be rigidly connected to a torque tube?
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.
Should solar panels be tilted?
The Clean Energy Council’s (CEC) solar guidelines for residential PV recommend a minimum tilt of 10° to ensure self-cleaning by rainfall; and for grid-connected PV systems, CEC recommends positioning panels at the angle of latitude to maximise the amount of energy produced annually.
Which direction should solar panels go?
As a general rule, the optimal direction for solar panels in the northern hemisphere is south. And in the southern hemisphere, the direction is north. So, the optimal direction for solar panels in the entire United States is south. The optimal tilt angle for fixed solar panels, as per a rule of thumb, is equal to the latitude of your location.
What is the tilt angle of solar panels?
If the sun is high in altitude, then the tilt angle would be small and solar panels would be more horizontal. For low altitudes, the tilt angle is large, and solar panels are vertical. The tilt angle for solar panels is dependent on the latitude of the sun. Fixed solar panels are a convenient and preferred choice.
How do I choose a solar installer?
Decide between a DIY or professional install. Solar involves electrical work on rooftops, only attempt DIY if you have experience. Hire a reputable, licensed solar contractor if using professionals. Verify they have an electrician on staff. Have the installer provide a detailed plan with panel placement, wiring runs, and electrical connections.
