Photovoltaic (PV) power plants, which are one of the most important renewable energy sources, provide great opportunities in terms of clean energy, due to their almost zero harmful environmental impact and relatively easy installation, considering the solar potential of our country. In addition, the government supports offered within the scope of the Renewable Energy Resources Support Mechanism (YEKDEM) offers great opportunities to bring renewable energy resources into the economy. According to the projection made in the annual program of the Presidency of our country, an increase of 1000 MW is expected in the amount of electricity produced from solar power plants in 2022. In addition, the share of electricity produced by solar energy in the total production is expected to be 8.5%. In this study; the design and simulation application of a rooftop, grid-connected distributed solar power plant with a capacity of 1MWp was presented through the PVsyst program. In the study, it was seen that the panel slope, the right PV module, and inverter selection are extremely important. The annual amount of energy that can be supplied to the grid has been obtained as 1246 MWh. In the simulation studies, it was emphasized that such a facility, which was established compared to a power plant with equivalent energy production, would contribute positively to the impact of climate change by not emitting 14000 tons of Co2. It has been observed that revenue of 4,485,600 ₺ can be obtained from such a newly established facility for the first ten-year period with a fixed fee purchase guarantee with the domestic contribution. Considering that the life of the power plant will be 25 years, it can be said that the facility investment will be extremely advantageous even without YEKDEM support.

“…Some features are designed to calculate panel distribution in the studied area, such as the Skelion feature in the SketchUp software [25]. The accuracy of all the software types varies between 5.00 and 18.75% in terms of percentage error, according to the results reported in [26,27]. The software that is most commonly used in estimating the spacing between arrays has limited accuracy and could not deal with the different configurations of panel distribution for either flat or non-flat terrains.…”

Minimizing the Utilized Area of PV Systems by Generating the Optimal Inter-Row Spacing Factor

et al. 2022

In mounted photovoltaic (PV) facilities, energy output losses due to inter-row shading are unavoidable. In order to limit the shadow cast by one module row on another, sufficient inter-row space must be planned. However, it is not uncommon to see PV plants with such close row spacing that energy losses occur owing to row-to-row shading effects. Low module prices and high ground costs lead to such configurations, so the maximum energy output per available surface area is prioritized over optimum energy production per peak power. For any applications where the plant power output needs to be calculated, an exact analysis of the influence of inter-row shading on power generation is required. In this paper, an effective methodology is proposed and discussed in detail, ultimately, to enable PV system designers to identify the optimal inter-row spacing between arrays by generating a multiplier factor. The spacing multiplier factor is mathematically formulated and is generated to be a general formula for any geographical location including flat and non-flat terrains. The developed model is implemented using two case studies with two different terrains, to provide a wider context. The first one is in the Kingdome of Saudi Arabia (KSA) provinces, giving a flat terrain case study; the inter-row spacing multiplier factor is estimated for the direct use of a systems designer. The second one is the water pump for agricultural watering using renewable energy sources, giving a non-flat terrain case study in Dhamar, Al-Hada, Yemen. In this case study, the optimal inter-row spacing factor is estimated for limited-area applications. Therefore, the effective area using the proposed formula is minimized so that the shading of PV arrays on each other is avoided, with a simple design using the spacing factor methodology.
