A comprehensive numerical modelling and investigation has been carried out to analyse the effect of wind loads on various solar array mounting frame structures using ANSYS 18 Workbench (Mechanical). Extensive damages of solar arrays and mounting frames have been reported the world over due to high winds. In this study, 6 array mounting frames types has been considered and subjected to 55m/s basic wind for Indian Wind Zone VI. Solar arrays considered of dimension 6mx4m consisting 12 PV panels each of size 1mx2m, with panel tilt angle varied from 10° to 50° degrees. Wind loads subjected to panels in solar array were considered as normal pressure force over top and bottom surfaces to simulate forward and backward wind direction. Maximum deformation and maximum stresses were determined using ANSYS Workbench and compared with various array mounting system arrangements for each case of panel tilt angle and subjected to both wind incidence.

AbstractThis study determines the lift force on a tilted solar PV panel with/without side plates (upward and downward types). The tilt angles are 15° and 30° and the wind incidence is at an angle of 0–180° (in increments of 15°). Measurements of mean surface pressure are conducted in a closed-loop wind tunnel. The corner vortices are lessened with the presence of upward or downward side plates for the wind angle of incidence of 0°. The mean surface pressure on the lower surface with downward side plates is more positive (greater wind loads). With upward side plates, there is less suction on the upper surface near the windward corner for the wind angle of incidence from 15° to 60°, resulting in significantly reduced wind loads.

Solar Analysis

Solar PV has been used extensively in the construction industry as non-renewable energy is not environmentally friendly and is costly. Building Information Modelling (BIM) can incorporate the solar energy application to reduce the dependency of non-renewable energy. This study attempted to propose a model of solar analysis using BIM software on existing buildings at Padang Besar, in terms of best orientation and optimum tilt angle. The finding of July 2017 shows that the ideal orientation of solar panel installation for the building is tilted 10° North and 20° West. Analysis indicated that the higher solar irradiance harvested contributed towards higher generation of power. The use of BIM software incorporating fieldwork data proved to be more convenient compared to the conventional physical method in proposing options for solar panel installation. The finding from the solar analysis of the proposed model indicates that solar insolation exposure on the roof increased by 1.45% compared to the existing roof design. Therefore, it can increase the renewable energy potential in an effective way.

Abstract As the exhaust rate of the conventional sources has geared up already, this is compelling the power industries to install the power plants based on the non-conventional sources so that future demand of the energy supply can be fulfilled. Among the various sources of renewable energy like wind, hydro, tidal etc., solar energy is the most easily accessible and available renewable energy source. Ensuring the feasibility of any energy source not only technical but also the economical perspective is the most important criteria. This paper has incorporated both the perspective and has done the techno-economic analysis to determine the optimum combination of the PV array size and battery size to minimize the overall electricity generation per unit. In this paper, a standalone solar PV system has been analyzed for the location of Jamshedpur, where an effort has been done to choose the optimum combination of the solar array and battery size within the desired range of LLP so that the electricity generation cost per unit can be minimized. The overall duration of the analysis has been done for a year and the outcome of the research has been verified with the help of MATLAB software.

Solar Tracking

The energy extracted from photovoltaic (PV) or solar thermal depends on solar insolation. For the extraction of maximum energy from the sun, the plane of the solar collector should always be normal to the incident radiation. Sun trackers move the solar collector to follow the sun trajectories and keep the orientation of the solar collector at an optimal tilt angle. Energy efficiency of solar PV or solar thermal can be substantially improved using solar tracking system. In this paper, an automatic solar tracking system has been designed and developed using DC motor on a mechanical structure with gear arrangement. The movements of two-axis solar trackers for the elevation and azimuth angles are programmed according to the mathematical calculation by using the Borland C++ Builder. Performance of the proposed system over the important parameter like solar radiation received on the collector, maximum hourly electrical power has been evaluated and compared with those for fixed tilt angle solar collector.

Proposed Model

The maximum electrical energy conversion efficiency of the Solar PV panel is up to 22% in normal conventional roof- top system under the temperature of 25˚C on Standard Test Condition (STC). In Indian climatic conditions, the atmospheric temperature is mostly above 35˚C to 45˚C, it incites 35˚C to 80˚C temperature on the PV panel. The black body of the PV panel absorbs more heat. This temperature affects the electrical efficiency of the panel significantly. This paper proposes the mathematical modelling of the solar PV panel for different solar irradiation and the temperature. The experimental evaluation is conducted in the latitude of 11.36 (N) and longitude 77.82 (E). The testing and monitoring was done with LabVIEW based National Instruments hardware such as NI cDAQ-9178, NI DAQ - 9227 and NI DAQ 9225. The comparative study between the simulated result and real time hardware results are discussed in this paper. The test result shows that the output of the proposed model mismatches with the experimental output of the solar PV panel due to the negative correlation between the efficiency and temperature for variable irradiation condition. It shows a power difference of 9.41W between the output of the proposed model and the experimental setup.

This paper aims to review the current development of vessels with solar power to reference the research and development of solar power vessels in Indonesia. The research method is a systematic literature review on the development of solar-powered vessels and includes an online survey of vessels using solar PV. This study found 86 solar-powered vessels consisting of boats, utility boats, ferries, houseboats, research, vehicle carriers, dive boats, and yachts developed from 1988 to 2020. These solar-powered vessels were built for various functions such as competitions, cleaning the environment, passenger transportation, and water tourism.  Production of solar-powered vessels is increasing in terms of production volume, PV capacity, and battery capacity. In terms of PV configuration, the solar array is dominated by a fixed array structure. However, there have been innovations using sun-tracking, wind tracking airfoils, and expandable channels to increase PV capacity.

A high-precision dynamic model of a flexible spacecraft installed with solar arrays, which are composed of honeycomb panels, is established based on the nonconstrained modes of flexible appendages (solar arrays), and an effective cooperative controller is designed for attitude maneuver and vibration suppression by integrating the proportional–derivative (PD) control and input shaping (IS) technique. The governing motion equations of the system and the corresponding boundary conditions are derived by using Hamiltonian Principle. Solving the linearized form of those equations with associated boundaries, the nonconstrained modes of solar arrays are obtained for deriving the discretized dynamic model. Applying this discretized model and combining the IS technique with the PD controller, a hybrid control scheme is designed to achieve the attitude maneuver of the spacecraft and vibration suppression of its flexible solar arrays. The numerical results reveal that the nonconstrained modes of the system are significantly influenced by the spacecraft flexibility and honeycomb panel parameters. Meanwhile, the differences between the nonconstrained modes and the constrained ones are growing as the spacecraft flexibility increases. Compared with the pure PD controller, the one integrating the PD control and IS technique performs much better, because it is more effective for suppressing the oscillation of attitude angular velocity and the vibration of solar array during the attitude maneuver, and reducing the residual vibration after the maneuver process.
