New approach for maximizing generation and optimal utilization of available space for solar PV system

Abstract

To accomplish an enormous demand of power with solar energy, a cost effective and optimum system has to be developed which works in synchronisation with the existing grid. The Government in developing countries like India is providing momentous opportunities and marvellous schemes to promote renewable energy sources like solar for generating power. This paper aims to analyse the generation of power from solar photovoltaic (PV) systems economically and efficiently as it is always a challenge for the design engineer to develop an economical and efficient solar PV system. Apart from technical issues, structural aspects also affect the power generation from PV modules. This paper proposes an innovative design of non-movable tracking system that enhances the power generation of PV modules by just providing two grooves in the mounting structure in place of the tracking system. A formula for the optimum space calculation for PV installation is also proposed in this paper. A comparative analysis of total annual energy generated by the hardware setup and the results obtained using software of the rooftop solar PV system has also been analysed for practical consideration. To verify the results, first, the system has been simulated using the PVSYST software considering all practical and existing realistic losses like PV loss due to irradiance and temperature, array soil loss, module quality loss, array mismatch loss, ohmic wiring loss, and inverter loss which formulate a bonafide case of consideration and then hardware implementation of the proposed system. The hardware and software results have been compared to analyse the proposed topologies adopted to address the aforesaid problems.

Optimization of tilt angle and experimental study of standalone PV system for clean energy home supply in Baghdad

“…The intercept radiation on the surface with different tilt angle is shown in figure [8] and [9]. The monthly daily average radiation result shown in figure [8] a and b for all year months, its clearly nots a unique optimum tilt angle for every month with which maximum solar radiation is achieved. Figure [9] evinces the contour chart of the catching radiation upon the surfaces having diverse angles of tilt all through the year.…”

“…If the module being parallel to the sun's rays, i.e., the angle of the module is perpendicular (90°), the light intensity fundamentally reaches approximately zero. Thus, at any specified instant, an array is going to create an ultimate result if focused straight at sun [7,8].…”

Orientation-Optimization Simulation for Solar Photovoltaic Plant of Cairo International Airport

“…Accordingly, Shadow Length should be calculated in order to place the PV panels in optimum position without shading. Dube, et al (2018) proposed generalized Eq. 20 calculating the shadow length, where is the solar altitude angle, and SL is the shadow length.…”

“…20 calculating the shadow length, where is the solar altitude angle, and SL is the shadow length. Figure 11 shows the shadow length calculation [26].…”

“…December 21 is taken because the sun altitude angle is maximum on this day, and thus the shadow length is maximum [26]. On December 21 at Cairo Airport, the solar noon is 11:53 [27], by using Eq.…”
