Settings

This section provides the settings of specific parameters of the project on:

• System:

Annual loss of system efficiency, this fall is mainly due to the decrease of efficiency of the photovoltaic modules. The system decreases over time the ability to produce energy.

Maximum voltage drop in DC area of system: is the maximum voltage drop in the cables achievable in the DC area of the system, this value should not be exceeded.

Maximum voltage drop in AC area of system: is the maximum voltage drop in the cables achievable in the AC area of the system, this value should not be exceeded.

Number of bypass diodes per module: is the number of bypass diodes present in the photovoltaic modules of the system. This value is used in the simulation for loss calculation for near shade .

Recognition of micro -nverter: It allows you to automatically treat the strings of a single module as part of the combination module + micro-inverter.

• Verifications:

System verification with minimum and maximum temperatures specified by the user, the system temperature, used in verification, can be defined explicitly by the user enabling this check and specifying the minimum and maximum temperatures. If this check is not activated the system temperature is calculated based on the minimum and maximum temperatures of the location.

System Temperatures, these are the minimum and maximum temperature reached by the photovoltaic modules. These values are used to calculate maximum and minimum voltage output from the PV array. The temperature reached by the modules is calculated by program when there are the maximum and minimum temperatures of the location of the system. These values are used in the absence of climate data on temperature or if the user chooses to directly set the temperature of the modules by selecting the previous check

Sizing on power of inverter, expresses, in terms of power, the exploitation of an inverter. This parameter is used by the program in the search of the inverter during the phase of sizing the system.

• Losses:

Specifies the percentage values of system loss. For losses due to shading can be specified if this value is calculated automatically by the program or if it is assigned by the user.

• Cables:

Maximum voltage drop in the cables, defines the maximum allowable of voltage drop percentage on each cable of system.

• Positioning:

It specifies whether the system is placed on the roof or on the ground.

• Economic analysis:

Inflation:: Is a percentual rise in the general level of prices in a period of one year. The program uses this index to increase yearly maintenance costs of the system.

Discount rate: The program uses this index to calculate the Net present value (NPV)

Currency text, is the text that the program will use for the currency currently set. The currency setting is done by the operating system.

 

When you create a new project, setting values are automatically assigned to those that have been set in the program settings (Menu: Home | Settings).

Modification of these fields affects only the current project.
