Photovoltaic technologies ensure the security and diversity of the energy supply without any negative impact on the environment, playing an important role in the production of electricity. At the moment photovoltaic systems oriented to energy performance have a relatively low efficiency, in contrast to the types and technologies of PV, but also the context of their use. The performance in terms of efficiency and long-term electricity generation depends on the current voltage parameters that differ depending on the...

The ambient temperature inside a building is essential for occupant comfort, and it influences directly the interior microclimate. Keeping the inner temperature at an optimum value involves energy consumption for heating and cooling. Energy consumption can be reduced by integrating phase change materials into the structure of the building. In thermal regime, with the integration of phase change materials, an integration model based on a mathematical method suitable for a thermal process analysis is described. This...

The evaluation of the catalog parameters of the voltage, the current of a PV module is essential in the design and implementation of photovoltaic systems, the reference parameters differ depending on the temperature of the operating cells and the different levels of radiation. The analytical methodology was the basis for creating a characteristic model for modeling a cell or a photovoltaic module in Matlab/ Simulink, using cell data at STC, considering standard global radiation G = 1000 W/ m2, the operating temper...

This paper aims to provide an overview of the technologies of passive heating and cooling by using phase change materials, integrated in the interior elements of constructions, to ensure the energy efficiency and the reduction of carbon dioxide emissions from buildings, approaching in at the same time the new and existing buildings. Considering that ensuring the internal thermal comfort of the occupants requires high energy consumption, the use of phase change materials by creating a passive energy storage system ...
