Abstract:

In solar energy systems that use solar panels, it's important to know the best tilt angle to optimize solar energy production. Monthly, seasonal, and annual optimum tilt angles were determined in this study using meteorological insolation data from many years in the provinces of Tekirdag and Konya, which are located in different regions of Turkey. At optimum tilt angles, monthly, seasonal, and annual total radiation on the tilted surface were 1516.7 kWh m-2 year-1, 1504.1 kWh m-2 year-1 and 1448.1 kWh m-2 year-1 in Tekirdag, respectively. In Konya, these values were 1851.4 kWh m-2 year-1, 1833

Abstract:

A key factor in the performance of PV panels is the tilt angle, adjustable via various tracking systems. Fixed tilt angle PV panels miss out on most of the solar radiation each day whereas continuous tracking systems are not always cost-efficient, rather impractical in some cases. Therefore, adjusting the tilt angle using a limited number of periods per year can be a good, compromised solution. In this paper, a new approach is proposed to maximize the impact of solar radiation on PV panels by adjusting their tilt angles. Based on a limited number of periods or intervals per year, the optimal d

Abstract:

Abstract A detailed research study was performed on the annual energy received by a fixed-tilt solar collector. A new clear-sky model of solar radiation was developed by combining existing clear-sky models. Then, this model, was used to perform optimizations with two different objectives. The first objective is to achieve the maximum-annual solar energy received by a solar panel, while the second is to balance its energy received so that it is more uniform over the course of a year. Each of these objectives have differing optimum tilt values, depending on the location and usage of a solar rece

Real-time position control of the journal in a hydrodynamic bearing demands continuous modification of the film thickness. Innovative adjustable bearings offer film thickness modifications in radial and circumferential directions through the flexible bearing elements. The position of the journal depends on the bearing element adjustments and the operating parameters. These adjustments also affect the static characteristic of the bearings. Hence, the position control requires an in-depth knowledge of the effects of bearing element adjustments on the bearing characteristics. In this paper, the m

Abstract:

The use of solar energy provides significant opportunities for high levels of clean energy production, particularly in southern regions of our country, given the high energy potential and long periods of sunshine. In recent years, with the increasing focus on sustainability efforts, the utilization of solar energy in our country has been steadily increasing. This study aims to examine the most suitable solar panel angles for the city center of Bursa and Uludag region, with a focus on determining the optimum panel angles on a monthly, seasonal, and yearly basis.

Abstract:

Most solar collectors in Nigeria are mounted without consideration of optimum tilt angle for maximum solar radiation. To address the gap, a flat plate surface solar collector of area 0.15 m2, hinged on horizontal support for quick adjustment of inclination between 0 to 90o was fabricated marked out at 1o intervals on a telescopic leg graduated in degrees. Measurement of the solar radiation at varying degrees of inclination was taken between 12:00 noon and 2.00 pm for 4 days at clear sky hours, within the week of nth day of the year. The measurements were taken for each month of the year at Mic

Abstract This study investigates the performance and economic aspects of a novel natural convection solar dryer designed for drying tomato slices. The dryer, featuring a floor area of 0.45×0.80 m2 with a north-south orientation, incorporates an optimally inclined solar collector (OISC). The optimization of the dryer's tilt enhances the greenhouse effect within the drying cabinet, leading to increased solar radiation intensity during the drying process. The increased total solar radiation input facilitates a more efficient drying rate by elevating both the internal air and crop temperatures. Th

In this paper, bifacial PV module was characterized to investigate the optimum height and tilt angle of bifacial solar cells in Baghdad location. The module elevation is a key factor in bifacial PVs because of the effect of self-shading on the amount of diffuse and albedo that can hit the rear side of the panel. This elevation is a function of latitude, daylight time, and season, which is never been determined before in Baghdad location up to our knowledge. Various heights above the ground were used (100, 120, 140, and 160cm), and for each height several tilt angles were taken (0°, 12°, 30°, 4
