In this paper, an attempt of performance evaluation of semitransparent and opaque photovoltaic (PV) modules of different generation solar cells, having the maximum efficiencies reported in the literature at standard test conditions (STC), has been carried out particularly for the months of January and June. The outdoor performance is also evaluated for the commercially available semitransparent and opaque PV modules. Annual electrical energy, capitalized cost, annualized uniform cost (unacost), and cost per unit electrical energy for both types of solar modules, namely, semitransparent and opaque have also been computed along with their characteristics curves. Semitransparent PV modules have shown higher efficiencies compared to the opaque ones. Calculations show that for the PV modules made in laboratory, CdTe exhibits the maximum annual electrical energy generation resulting into minimum cost per unit electrical energy, whereas a-Si/nc-Si possesses the maximum annual electrical energy generation giving minimum cost per unit electrical energy when commercially available solar modules are concerned. CIGS has shown the lowest capitalized cost over all other PV technologies.

The performance of an amorphous silicon solar PV module is tested at various irradiance levels, operation temperatures and tilt angles using a solar simulator. Electrical efficiency, V-I characteristics and power conditioning curves are generated at various solar irradiance levels of 400, 700 and 1000 W/m2, cell operation temperature range of 40 to 100°C and various panel tilt angles of 0°, 15°, 30°, 45° and 60° with horizontal. Solar equations are used to compute the maximum swing angle of the sun away from the normal position of the panel at noon (l) during different months and latitudes. Analogy between the simulated study and l (for real operation conditions) for polar mounted inclinations of PV panels, winter & summer maximization inclinations of the PV panels and south facing vertical walls/windows for different months of the year and at various latitudes is established and the effect of l on the percent reduction in maximum power produced (Pmp) by the PV solar panel is studied. The tilt angle dependence shows that the panel produces highest Pmp at l = 0° (tilt angle of the panel when the light source is normal to the panel surface). It is also observed that Pmp decreases by about 9%, 14 % and 19% when l is 15°, 30° and 45° respectively as compared to the normal position of the panel. Newton-Raphson’s technique is used to theoretically compute Imp, Vmp & Pmp and compared with the experimental values generated using the solar simulator within less than 5% deviation.

Multidisciplinary Optimization of Thermal Insulation Layer for Stratospheric Airship with a Solar Array

Stratospheric airships with a solar array have demonstrated overwhelming superiority in many aspects, such as earth observation, meteorological survey, and communication relay. The solar array supplies sufficient power for the airship to be in flight for months, but excessive heat is also transferred to the airship, causing high overpressure of inner gas. However, the optimal arrangement of the insulation layer on the airship has not been investigated. The theoretical method, including the geometry, thermal, and energy models, is developed and validated. The distribution of the temperatures and power of the solar cells, with different installation angles on the curved surface, is investigated. The thickness of insulation layer has a significant effect on the solar output power and internal pressure of the airship. An optimized configuration of the insulation structure is proposed, in order to improve the total output energy of solar array. The optimized configuration of insulations helps to reduce the structural mass by 24.9% and increase the payload mass by 9%. Moreover, the optimized arrangement improves the output energy of solar array in a year, and the maximum improvement is 8.2% on the winter solstice. The work displays the optimization of the thermal insulation layer for the stratospheric airship with a solar array, in order to improve the everyday energy acquirement during flight in a year.
