Physical Description

The prototype built followed the design presented in figure 2. This system incorporates a PV-cell 150mmx150mm, Pmax=1,12W, (Polycrystalline Silicon wafer) and the whole structure is made of aluminium alloy. In fig. 6 the global developed prototype is shown. The control unit was developed using an industrial Siemens S7-300 PLC (Programmable Logic Controller). Figure 7 details […]

Danish tests

The tests at DTI were done outdoors on a side by side configuration with three test panels of 3.5 m2 each and a single PV reference module. PV modules were each 190 Watt from Evergreen. System 1: SolarWall with two PV modules on top, variable flow (high) System 2: SolarWall with two PV modules on […]

Control Algorithm

The software used for the PLC programming was the Siemens Simatic Step 7 [13], with the Simatic S7 Prodave V5.5 [14] needed for the communication between the Scada system and the PLC network. The designed control algorithm was implemented using the Ladder Diagram language [15]. The developed control algorithm is illustrated in fig. 8. A […]
