Consequences of Reducing the Cost of PV Modules on a PV Wind Diesel Hybrid System with Limited Sizing Components

الملخص EN

The use of renewable resources for power supply in family homes has passed the stage of utopia to became a reality, with limits set by technical and economic parameters.

This paper presents the results of a project originated from the initiative of a middle-class family to achieve energy independence at home.

The starting point was the concept of home with “zero energy” in which the total energy available is equal to the energy consumed.

The solution devised to meet the energy demand of the residence in question is a PV wind diesel hybrid system connected to the grid, with the possibility of energy storage in batteries and in the form of heating water and the environment of the house.

As a restriction, the family requested that the system would represent little impact to the lifestyle and landscape.

This paper aims to assess the consequences of reductions in the cost of the PV modules on the optimization space, as conceived by the software Homer.

The results show that for this system, a 50% reduction in the cost of PV modules allows all viable solutions including PV modules.
