ABSTRACT :
Photovoltaic (PV) systems have received a lot of attention in recent years due to their ability to efficiently convert solar energy into electrical energy, which offers significant benefits for the environment. Albania has great potential for solar energy. It receives around 2100-2700 hours of sunlight, making solar energy accessible. This study reviews the challenges of implementing photovoltaic systems in the mountainous areas of Vlora, specifically in the Llogora National Park, which is 910 meters above sea level. This area is highly frequented by tourists. Tourism is the most important sector in the park and has the greatest potential to be a source of sustainable income. The basic concept is the utilization of solar panels in businesses operating in this area. The energy network challenges and climatic conditions are detailed. The performance of PV system installation, energy costs, and types of panels that can be installed with one axis or two axes are evaluated. By using cost data per unit for materials and different subsystems, it is possible to identify an individual panel or panel system that minimizes the cost of produced energy. The cost per kWh for different PV system technologies in the network ranges is 0.111 EUR/kWh. However, on the other hand, compensating for network interruptions, and low voltage problems in the main network, which affect businesses in this area, is a good investment.
