    PANEL HANDBOOK aH72 SK V 6.0 1 CONTENT, WARNINGS AND PRECAUTIONS Note: A copy of this document is sent inside the solar panel package and is the property of the customer. It must be kept by the person responsible for maintenance in a safe place.

  • Page 6: Care, Maintenance And Warranty

    PANEL HANDBOOK aH72 SK V 6.0  If damages are discovered, a joint and immediate inspection by the carrier and the consignee will be requested. Damaged material shall not be removed from the receiving location. Photographs of the damages must be taken.

  • Page 7: Care And Maintenance

    PANEL HANDBOOK aH72 SK V 6.0 2.1 Care and maintenance There are several periodic maintenance requirements for hybrid solar panel installations. The following table summarizes the inspections and actions to be taken to obtain the maximum performance of the system.

  • Page 8: Solar Fluid Test

    PANEL HANDBOOK aH72 SK V 6.0  Check for solar fluid leaks on a quarterly basis. Leaks can cause a dilution of the thermal fluid which, if not tested and maintained, could allow freezing due to loss of glycol. In addition, make- up water can cause the accumulation of hardness inside the heat absorber, thus decreasing the performance of the system.

  • Page 9: Warranty Policy

    ABORA ENERGY S.L. is the manufacturer of the hybrid solar panels aH60, aH60SK, aH72 and aH72SK. ABORA guarantees that the panel is free from malfunctions at the time of sale. For more information on product warranties, please read the conditions specified in the warranty document.

  • Page 11: Panel Rails

    PANEL HANDBOOK aH72 SK V 6.0 Fig. 3. Detail of the distances between triangle anchors depending on the inclination 3.1.4 Panel rails The panel rails, upper and lower, are formed by joining the 50x85 profiles using the connecting strips supplied in the accessories set. The profiles are supplied in different sizes depending on the number of panels to be installed per row and, therefore, the final length of the rails varies according to this figure.

    PANEL HANDBOOK aH72 SK V 6.0  Place the next collector after the previous one to carry out the operations mentioned above until all the collectors are anchored and connected to each other. Fig. 9. Placement distance of first collector and anchorage detail to structure Fig.

  • Page 15: System Design Considerations

    PANEL HANDBOOK aH72 SK V 6.0 4.1 System design considerations Maximum operating pressure: Although the maximum test pressure for the modules is 10 bar, a maximum system pressure of 3 bar is recommended. A qualified installer must install the system in accordance with all requirements defined in the project, building regulations and codes, health and safety legislation and any local regulations in force at that time.

Detail of rows connections 4.6 Circulator pump and piping The selection of the pump is fundamental for the system to obtain its maximum efficiency and is determined at the design stage.

  • Page 17: Control System

    PANEL HANDBOOK aH72 SK V 6.0 4.7 Control system There are many manufacturers of solar thermal controllers or regulators. Depending on the configuration of the installation, the controller that guarantees the perfect operation of the installation will be selected, taking into account that the simplest installation will include at least 2 temperature sensors: one in the panel and another in the tank and 2 relays or control capacity: one for the circulator pump and another for the heat sink (with 3-way valve or another pump).

  • Page 18: Cleaning And Filling The System

    PANEL HANDBOOK aH72 SK V 6.0 4.8.1 Cleaning and filling the system Once the installation is completed, it will be cleaned and filled. 4.8.2 Leakage check of the collector field To avoid problems with faulty connections or possible pores, the first test for tightness should be carried out, using water or air.

  • Page 19: Installation System Bleeding

    PANEL HANDBOOK aH72 SK V 6.0 Important. The heat transfer fluid is essential in areas with minimum temperatures equal to or below 0 degrees to avoid freezing, and must also be able to withstand high temperatures. Its freezing temperature should be checked with a density meter.

    PANEL HANDBOOK aH72 SK V 6.0 Fig. 13. Diagram of recommended initial pressure in the circuit As for the final flow rate of the installation, it is recommended to adjust it to 50 liters hour per panel. Its adjustment will be done through the speed of the pump, throttling its shut-off valve until the desired flow is achieved.

Standard diagram of the photovoltaic part WARNING Risk of electrocution!  Before starting work on the general electrical cabinets inside the building, you must disconnect the power supply entering the electrical cabinets and isolate the photovoltaic system to avoid double feeding and possible electrical shocks.

  • Page 23: Installation Guidelines

    PANEL HANDBOOK aH72 SK V 6.0  During installation, protect the hybrid solar panels from sunlight because, when solar radiation comes in contact with the surface of the panel, it will produce electrical energy. Only qualified technicians should install or perform maintenance work on the panels. For maintenance work, the panels should be properly covered.

  • Page 24: Direct Current Pv Connectors

    PANEL HANDBOOK aH72 SK V 6.0 cable's own weight can generate electrical contact failures, which can lead to electrical arcs with the corresponding consequences, such as fires. 5.2.3 Direct Current PV connectors The hybrid panels have a connection box on the back side from which two cable strands (one positive and one negative) with special PV connectors (compatible with MC4 connectors) male and female come out.
