Off-grid hybrid renewable energy systems represent the most modern and flexible solutions that can cover a wide range of energy efficiency needs for household consumers. In the current context, these systems must be taken into account by most household consumers, given the fact that the price of energy has increased. This paper proposes an experimental analysis of the behavior of such a system, in real operating conditions, considering two renewable energy sources, wind and photovoltaic sources, using an experimental stand. It can be considered a testing platform for hybrid energy production systems, in that the power installed in the two sources can be scaled up. The platform has the advantage of allowing the implementation of different load and wind curves through a programmable logic controller; in this way, it is possible to evaluate the degree of coverage of the energy consumption produced from renewable sources, in the north-east of Romania, in the Suceava County region. The experimental study also involves an analysis of the storage capacity in relation to the consumption and the electricity produced by the two renewable sources. In this regard, three scenarios differentiated by the state of charge (30%, 50% and 70%) have been established. The results indicate that, for each of the imposed scenarios, the energy required to cover consumption is produced by renewable energy sources (42%, 47% and 53%), to which the energy stored in batteries (39%, 28% and 18%) is added.

“…The greatest attention for alternative renewable energies is directed towards solar energy. Among the solar systems that are widely used we name two categories of technologies that use solar energy: the solar unit that converts the radiation captured from the sun into electricity (PV) and the solar thermal cell (ST), a method used to obtain hot water, used to heat residential spaces and industrial spaces [1][2][3][4].…”

“…Because the specific features of photovoltaic cells are influenced by irradiation and temperature, they are shaped by a circuit design. The manufacturers of the modules provide information about the components that make up these modules, but also about the PV characteristics, specifying certain points of them (current-voltage) called optimal operating points equivalent to a single point of maximum power [1][2][3][4][5][6][7][8].…”

With the increase in energy demand, the necessity for photovoltaic panels to be as efficient as possible has also increased. In order to achieve the highest possible performance, solar cells depend on a number of environmental elements such as: temperature, shading, cloudy weather, deposits on the surface, dust, solar irradiation, nighttime darkness, etc. All these factors ultimately result in a decline in photovoltaic panels performances. With the help of modeling and simulation programs, complex systems with high performance can be designed and realized, considering the advantage of avoiding manufacturing costs through their physical testing. Based on the electrical and thermal characteristics extracted from the Sanyo producer's data sheet, the proposed commercial photovoltaic module HIT-240HDE4, is implemented in the MATLAB environment under standard and real test conditions. The article presents the modeling and simulation in the MATLAB program of the proposed photovoltaic module, for the analysis of the electrical performances under the described conditions. Also, the article addresses the analysis issue of the operation considering the chosen module, under the same conditions.
