System

The system section of BlueSol provides the tools to define the composition of the PV system in all its aspects in order to carry out design and verification. BlueSol implements a software simulator of a photovoltaic system and therefore each element of the system will be defined and present within the simulator.

Scheme of system

The scheme of the photovoltaic system is represented by a tree structure, where each node identifies a component of the system:

• Electricity grid

• Electrical AC panel

• Inverter

• Electrical DC panel

• String

• Battery

• Inverter/Charger

The tree diagram, which represents the system, starts from the electricity grid and expands to the strings. Selecting tree nodes are displayed, within the panel next to the diagram, all the information related to the component allowing the consultation and editing. Moreover, for each component of the system are visible electrical parameters specific.

Electricity grid

Defines the part of the system that connects to the grid. The parameters that can be set differs depending on whether the delivery of electricity occurs in low or medium voltage and that the connection is single phase or three phase.

Electrical AC panel

Defines the configuration of the electrical panel in AC current and the components with which it is made.

In this section you can set:

• Electrical protection group on AC

• Isolation Transformer

Inverter

Conversion device from direct current to alternating current, the system may contain multiple inverters of different models.

In this section you can set:

• MPPT of inverter

• Change the inverter model

Electrical DC panel

Defines the configuration of the electrical panel in DC current and the components with which it is made.

In this section you can set:

• Electrical protection group on DC

String

Sequence of photovoltaic modules wired in series; each string is characterized by:

• Type of photovoltaic module (same for the whole string)

• Number of PV modules

• Angle of inclination of the modules (tilt)

• Angle of orientation (azimuth)

• Far shading

Each string of the system can have its own orientation (tilt and azimuth) different from that of the other strings of the system.

In this section you can set:

• Model of the photovoltaic module with which the string is composed

• Number of modules with which the string is composed

• Orientation

• Far shading

The scheme of system which is realized, using the dimensioning wizard or modeling of the system, it can be modified using the tools provided by BlueSol:

• Modify the schema of the system

• Changing the parameters of system elements

• Resizing the system

• Rename the names of system elements

• Analize the producibility of system

• Verify the system

Battery

Defines the composition of a battery bank as a sequence of batteries in series and in parallel. It can be present in both DC section and AC section.

In this section you can set:

• Type of battery

• Number of batteries in series

• Number of batteries in parallel

Inverter/Charger

It defines the Inverter/Charger that recharges the batteries in one direction and transforms the charge in alternating current in the other direction. This device is only used when the system is AC-coupled battery storage.

In this section you can set:

• Type of inverter/charger
