      <abstract xml:lang="ru">
        <p>Куба традиционно считается страной со слабо развитой промышленностью. Удельный вес горной и металлургической промышленности в валовом объеме промышленного производства республики невелик – порядка 3 % ВВП. Разработка месторождений и добыча никелевых руд являются значимой отраслью экономики Республики Куба, так как наибольшие запасы никеля и кобальта на Североамериканском континенте находятся на территории страны. Фактором роста данного сектора экономики может послужить развитие энергосистемы страны. Ввиду климатических особенностей и невозможности интегрирования в энергосистему новых мощностей путем строительства гидроэлектростанций перспективным направлением является солнечная энергетика. Определение возможности применения систем слежения за солнцем для повышения выработки электроэнергии солнечными электростанциями является одной из основных задач, с которой сталкиваются инженеры и специалисты по возобновляемым источникам энергии. В настоящее время на Кубе не существует систем слежения за солнцем, способных предоставить информацию для оценки эффективности этой технологии на территории страны. Отсутствие необходимых технологий, а также высокая стоимость разработки солнечных электростанций с системами слежения ограничивают повсеместное внедрение подобных комплексов. Отсюда вытекает задача создания недорогой экспериментальной модели, позволяющей проводить оценку эффективности применения систем трекинга в конкретных погодных условиях Республики Куба. Данная модель позволит в будущем повысить эффективность электротехнических комплексов с солнечными электростанциями, обеспечивающих электроснабжение объектов минерально-сырьевого комплекса и других регионов.</p>

      <abstract xml:lang="en">
        <p>Cuba is traditionally considered a country with an underdeveloped industry. The share of the mining and metallurgical industries in the gross industrial production of the republic is small – about 3 % of GDP. The development of deposits and the extraction of nickel ores is an important sector of the economy of the Republic of Cuba, since the largest reserves of nickel and cobalt on the North American continent are located on the territory of the country. The development of the country energy system can serve as a growth factor in this sector of the economy. Due to climatic features and impossibility of integrating new capacities into the energy system through the construction of hydroelectric power plants, solar energy is a promising direction. Determining the feasibility of using solar tracking systems to increase the generation of electricity from solar power plants is one of the main challenges faced by engineers and renewable energy specialists. Currently, there are no solar tracking systems in Cuba that can provide information to assess the effectiveness of this technology in the country. The lack of the necessary technologies, as well as the high cost of developing solar power plants with tracking systems, limit the widespread introduction of such complexes. Hence follows the task of creating an inexpensive experimental model that allows assessing the effectiveness of tracking systems in specific weather conditions of the Republic of Cuba. This model will allow in future to increase the efficiency of electrical complexes with solar power plants, which provide power supply to the objects of the mineral resource complex and other regions.</p>
