“…Accurate wind data will make the system more realistic. Also, a tracking system was not included in this study, and a research lead by Rahimi [37] found that using hybrid wind sun-tracking improves the performance of the PV cell by 49%. The load profile used in this study was estimates of load patterns, which will change for individual houses, schools, and the health clinic.…”

Around 14% of the global population does not have access to electricity. About 95% of those are living in rural Sub-Saharan Africa. Often in these regions, diesel generators are the only source of electricity. The operating cost of these diesel generators is high. However, solar and wind energy are available in most of African countries. This study presents the analysis of designing an off-grid hybrid system with a wind turbine, PV, diesel generator, and battery to power a hospital, school, and 200 household village in four locations across Somalia. The research investigated the availability of wind-solar resources in selected locations. Designing of the system and economic-technical calculations were performed using HOMER. The selection of the optimum design was based on the Cost of Electricity and Net Present Cost. The results show that for Kabaal and Ceel Buur, a WT-PV-DG-Battery is the optimal system as the wind resource in these regions is high. For Saakov and Baki, a PV-DG-Battery system proves to be optimum as the wind resource is limited here. The study also evaluated the control strategy and proved that combined dispatch was the most cost-effective for these locations. The study concluded that hybrid systems are more economical than diesel systems.

Currently, solar energy is considered one of the most suitable options for overcoming the problems of fossil fuel depletion, and global warming. Also, the high costs associated to photovoltaic systems, renders the maximum utilization of solar cells, a fundamental and undeniable necessity. Technical-economic-environmental analysis, using HOMER software, was performed under four different scenarios: without the tracker, with the horizontal axis tracker, with the vertical axis tracker, and with the dual-axis tracker. Consequently, the best configuration was chosen for each scenario. The optimal system for all four scenarios, in the circumstance of disconnection from the grid, only involves the solar cells, while in the circumstance of connection to the grid; both the solar cells and the wind turbine are included. The results demonstrate that in the off grid situation, the scenario involving the use of a vertical axis tracker would be the most cost-effective, with the price of 0.812 $/kWh for energy produced, while the lowest price for producing one kg of hydrogen is $77.97 is attributable to the scenario without the use of a solar tracker. In the circumstance of being connected to the power grid, the scenario involving the use of a vertical axis tracker would be most cost-effective, with the price of each kWh of energy produced equal to $ 0.223. At the price of $29.33 per kilogram, the scenario involving the use of a vertical axis tracker would also be most suitable for the production of hydrogen. Another important fact revealed through the results, is the crucial role of dump load, in the provision of the heat required in an off-grid situation. However, dump load is not associated to heat provision in a grid-connected situation.

“…21 This method was introduced in a hybrid with a wind-tracking system to cool down the PV panels. 22 A two-axis tracking system was used to track the sun, whereas a single-axis tracking system was used for the wind. Their outdoor experiment concluded that this hybrid wind-sun tracking system has an overall increase of 7.4% in the output power compared with the two-axis tracking system.…”

Summary Enhancing the performance of a concentrator photovoltaic (CPV) system by integrating a solar tracker to concentrate the solar irradiance on the target area is important. Thus, a dual‐axis elliptic solar tracker is designed, fabricated, and experimentally evaluated. The altitude and solar azimuth angles of the tracker are adjusted based on governing equations to track the sun. The tracker's error is measured using a series of light‐dependent resistors. Then, the tracker is used to assess the CPV system's performance at a solar concentration ratio of 50. The results indicated that the maximum error in solar azimuth and altitude angles equals 0.5°. Furthermore, the measured errors are independent of dust and cloudy weather. By integrating the concentrator PV system and solar tracker, the direct normal irradiance slightly varies throughout the day from 750 to 980 W/m2. At this condition, the maximum measured solar cell temperature is approximately 42°C with a maximum attained electric power of 1.08 W for a solar cell area of 1.012 cm2.
