“…The LCC method has been used to study the economic feasibility of investing in pv panels in Jordan [20] and Malaysia [21]. The method has also been applied in the process of optimizing the size of pv installations [22]. The CBA method, on the other hand, has been used to compare a pv installation with an alternative natural gas power generation installation [23] and also in the context of demonstrating the economic viability of a pv installation in Kuwait [24].…”

In this article, the authors analyzed two extreme investment variants considering the installed capacity of Poland’s residential pv installation: (a) pv installation meets electricity demand only in the first year of operation, and in each subsequent year it is necessary to purchase electricity at market prices; (b) installation meets electricity demand even in the last year of operation, and in each previous year, the excess of generated electricity needs to be transferred back to the grid, with the limited (by law) right of drawing it from the grid for free in the future. In the article, a sensitivity analysis was performed, and profitability changes were established based on the NPV value, depending on case (a) or (b). The performed analyses showed that the pv installation profitability should not be analyzed, assuming only one moment when it meets 100% of the household’s electricity demand. It was shown that the choice of such a moment, depending on the value of particular technical and financial parameters, can lead to a change in the NPV value, even over 10%. Although the studies were done for Poland, such an approach can be implemented in other countries.

“…Therefore, it is crucial for the maximum amount of sunlight to be captured by the solar PV module. Indirectly, this also helps avoid oversizing the solar PV system and ensuring that it operates efficiently [29]. Hence, to have maximum PV power output, two essential factors, namely, optimum tilt angle and solar PV modules orientation, are crucial for designing and installing solar PV panels.…”

An ongoing project to implement a mini standalone solar photovoltaic (PV) generation system of 2.5 kWp capacity at the eco-tourism centre of Liogu Ku Silou-Silou (EPLISSI), Sabah, was initiated in 2019. Since the solar panel support (ground mounting) used in this project will be erected separately, the main goals of this study are to estimate the optimum tilt angle, βopt, and orientation for the solar PV modules. To achieve these goals, the Liu and Jordan isotropic diffuse radiation model was used (1960). Another three isotropic diffuse sky radiation models (Koronakis model, Badescu model, and Tian model) were applied to estimate the optimum tilt angle with the orientation kept facing due south. For verification purposes, the PV power output data obtained from an online PV simulator known as Global Solar Atlas or GSA 2.3 was used and compared to the results of the four isotropic models. The results suggest that the Tian model is more suitable for approximating insolation, as it was proven to have the lowest difference among all models and is in close agreement with the result of the optimum tilt angle provided by GSA 2.3. However, the outcomes demonstrated from the isotropic models propose an error up to 30% (in the range of 31% to 32%) as compared to GSA 2.3.

Stand-Alone Photovoltaic (SAPV) systems have been a popular mode of electricity generation especially in remote areas which deprived of grid electricity. However, one of the main challenges in the development of such systems is optimal system sizing. An undersized system causes failure of meeting the load demand. Thus, this paper presents Cat Swarm Optimization (CSO) for optimal sizing of an SAPV system. A single objective function was formulated for the sizing optimization problem in which models of system components, i.e. PV module, battery, charge controller and inverter, each represented in integer codes, were transcribed as decision variables whereas the Loss of Power Supply Probability (LPSP) was set as the objective function that needs to be minimized. Prior to the optimization, an Iterative Sizing Algorithm (ISA) was initially developed to produce the optimal sizing solution using non-computational intelligence approach. The solution from ISA served as benchmark for CSO. Later, CSO was used to select the optimal model of PV module, battery, charge controller and inverter such that the LPSP was minimized. The results showed that CSO was able to yield similar LPSP as recommended by ISA. Besides having computation time of approximately 3.65 times lower than ISA, CSO was also found to be superior by producing lower LPSP when compared with Evolutionary Programming (EP).
