Solar photovoltaic tracking systems for electricity generation : a review
Sebastijan Seme, Bojan Štumberger, Miralem Hadžiselimović, Klemen Sredenšek, 2020, pregledni znanstveni članek

Opis: This paper presents a thorough review of state-of-the-art research and literature in the field of photovoltaic tracking systems for the production of electrical energy. A review of the literature is performed mainly for the field of solar photovoltaic tracking systems, which gives this paper the necessary foundation. Solar systems can be roughly divided into three fields: the generation of thermal energy (solar collectors), the generation of electrical energy (photovoltaic systems), and the generation of electrical energy/thermal energy (hybrid systems). The development of photovoltaic systems began in the mid-19th century, followed shortly by research in the field of tracking systems. With the development of tracking systems, di%erent types of tracking systems, drives, designs, and tracking strategies were also defined. This paper presents a comprehensive overview of photovoltaic tracking systems, as well as the latest studies that have been done in recent years. The review will be supplemented with a factual presentation of the tracking systems used at the Institute of Energy Technology of the University of Maribor.

A sustainable transport solution for a Slovenia town
Matjaž Knez, Ali Naci Celik, Tariq Muneer, 2014, izvirni znanstveni članek

Opis: Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel-based transport poses two chief problems—local and global pollution, and dwindling supplies and ever-increasing costs. An elegant solution is to gradually replace the present automobile fleet with electric vehicles (EVs). This article explores the economics and practical viability of the provision of solar electricity for the charging of EVs by installation of economical available Photovoltaic modules. A steep decline in the module, inverter and installation costs is reported herein. Present estimates indicate that for the prevailing solar climate of Celje—a medium-sized Slovenian town—the cost would be only 2 euros and 11 cents per kWh of generated solar electricity.

Green logistics - a solar warehouse concept
Matjaž Knez, Péter Bajor, Sebastijan Seme, 2011, izvirni znanstveni članek

Opis: Transportation and logistics are responsible for climate change as they produce greenhouse gases and contribute to the increasing share of fossil fuels, such as oil, in global energy consumption. Supplying the required energy for the transport and logistics sector in an environment-friendly way (based on electric or hydrogen fuels) is one of the main challenges for mankind. Material handling processes have a significant energy demand in warehouse operations, and the application of electricity-driven vehicles and equipment is widely accepted. With the effective use of available green electricity sources - like photovoltaic and wind energy - in the warehouse, we could provide energy for these operations. This article, based on laboratory data, describes a solar-warehouse concept and analyzes the critical parameters, such as energy demand of processes and vehicles, the characteristics of consumption and production, the alternative solutions of electricity storage and fast-charging.
