Iberoamerica is home to some of the regions with the greatest solar potential worldwide and many of them are already very active and relevant specific project focuses. These focuses are addressing both applications related to the generation of heat and electricity for isolated environments and other emerging applications such as the integration of solar and photovoltaic plants in national and regional distribution networks, water treatment or industrial process feeding and productive. To this, we must add the demonstrated involvement of institutions and governments in the fight against climate change, as reflected by the adherence of almost all of the Latin American states to the agreements of the derivatives of the different summits of the United Nations on Climate Change and the increasing adoption of initiatives to promote and finance these types of sources in their national laws.
It is therefore an unstoppable process and it may be of interest to offer future Latin American engineers and professionals the opportunity to take advantage of the experience in this area of Spanish research centers and universities. This interaction also has the advantage of its bidirectionality since, this type of process serves for the Spanish centers to improve their capacities through the requirements and experiences from the projects developed in Latin America.
The CIESOL (www.ciesol.es), Solar Energy Research Center, is a mixed center of the Universidad de Almería and the Solar Platform of Almería (www.psa.es). Founded on the basis of an agreement signed in 2006, it gathers more than 25 years of experience in collaborative projects between both institutions. Although the center is primarily dedicated to applied research activities in the field of solar energy, the available infrastructures and the experience accumulated by its staff allows it to address, in addition, specific training activities in 3 modalities: 1) training of doctoral students who begin his research career, 2) support for regulated academic activities in undergraduate and master's studies of the Universidad de Almería and 3) the realization of specialized courses at the request of companies or institutions. Related to the course contents, the center has specialists in modeling, advanced control and monitoring of thermal and photovoltaic solar installations for applications in buildings and industry, including among other processes desalination and water treatment. Among the infrastructures available for demonstration activities, the center has a large-format solar installation of 80 flat panel modules (160 m2), a 9 kWp photovoltaic installation, a thermal storage system consisting of two 5000 l tanks and a system of 70 kW absorption cooling connected to the solar field. Different thermal and electrical loops interconnected to the system provide thermal energy to different applications in the building. To these, and on a larger scale, you can also add a 1 MW photovoltaic power plant that provides more than a quarter of the electricity consumed by the Universidad de Almería . Additionally, the center has a wide network of contacts with companies and professionals in the sector that collaborate in training and dissemination activities.
The course's main objective is to provide its students with a set of knowledge and skills in calculation tools that allow them to make basic designs and dimensions of solar thermal and photovoltaic installations for applications in their usual work environment. In order to obtain this general objective, the following particular objectives will be addressed:

The methodology to be applied includes both theoretical classes, which will occupy 40% of the teaching dedication and practical activities, which will account for 60% of the student's dedication and will be of 3 types: problem solving and application cases, use of computer tools and guided visits to facilities. Practical activities include student tests and assessments. The distribution of the classes and their format will be:
- Master classes on theoretical content (40%, 32 hours). Using the treaties indicated in the bibliography as well as the UAL's own material, the corresponding classes of theory will be taught using the classical means (transparencies and explanations on blackboard)
- Class of problems and calculations for application cases (25%, 20 hours). They will be carried out in the classroom, promoting both the autonomous work and the collaborative work of the students, based on relationships of problems and practical cases prepared ad hoc for the course, including the consideration of the location of facilities in different locations in Latin America.
- Use of modeling and sizing tools (20%, 16 hours). They will be taught in a computer room of the UAL in which access to the specific software proposed in the course will be provided (SAM, TRNSYS, F-chart). A basic tutorial will be provided in each of them and an application case.
- Program of guided technical visits to solar installations (10%, 8 hours). Two full days of the course will be devoted to visits to facilities guided by specialist technicians responsible for them.
- Tests and evaluations (5%, 4 hours)
