Thermal Expansion Compensating Bolts: Design bolts with threaded expansion sections that can stretch within a certain range to accommodate thermal expansion. High-Elasticity Bolts: Use special alloys, like nickel-chromium steel, to manufacture bolts that retain high elasticity even at elevated temperatures, reducing thermal stress.
At INDEX you can find a wide range of fixings and accessories designed specifically for this purpose: Adjustable triangles. They are ideal for fixing solar panels at an angle and are mainly made of steel and aluminium. They are used as a complement to the support and help to regulate the inclination of the panels on the roof.
Furthermore, the panels served as a cooling source for PV. Ghenai et al. designed a standalone hybrid renewable energy system consisting of solar PV and fuel cells to meet the energy requirements of 150 houses in Sharjah, UAE. The effects of dust and temperature were also investigated.
Thermal Stress and Thermal Expansion Issues Example: Solar panels absorb heat during the day and dissipate it at night, leading to material expansion and contraction. If fasteners cannot accommodate this thermal expansion, connections may fail or structural damage might occur. Specific Solutions:
Several researchers focused on the optimisation of tilt angle for PV system installation. A study proposed a novel model for the optimisation of the tilt angle measurement method and opined that the complex and changeable mountainous topography distinguishes it from plain regions .
The optimum installation position for solar PV shadings is south facade with a 30° tilt angle for maximum electricity generation. The optimal tilt angles during the spring, summer, autumn and winter seasons should be 22.0°, 6.0°, 48.0° and 61.3°, respectively. The yearly average tilt should be 34.3°.
Typically, solar panels have accounted for temperature swing, and the mechanical expansion and contraction associated with it, through flexibility in construction materials and, on a relatively small scale, in each module. To appropriately account for temperature fluctuations on a system level, however, the racking must also be considered.
