Page 8: Electrical Values
INSTALLATION MANUAL – 2012 The maximum power value, open circuit voltage and short circuit current of any individual module will be -0% to +3% of these values. Specifications are subject to change. Electrical Values In actual conditions, the variation of the parameters of operation for the cells will be related to the variation of irradiation received and the actual temperature. -

INSTALLATION MANUAL – 2012 Potential Power Curve Figure 4. Curve of the potential produced by a photovoltaic module in reference to the working point. In the above figure, it can be observed that there is a point for which the product (I x V) reaches its maximum. -
Page 11: Junction Box
INSTALLATION MANUAL – 2012 JUNCTION BOX The junction box can be found on the backside of the module. The module’s cells are soldered in a series and terminate at four points within the junction box where the current passes through two bypass diodes, the circuit board, and +/- outputs before entering two isolated copper cables with multi-type connectors. -
Page 12: Diode Characteristics
INSTALLATION MANUAL – 2012 Any shadowing of cells resulting from the projection of any object or from the accumulation of dirt or debris can result in reverse voltage. The junction box contains three bypass diodes to avoid this problem. The reverse polarization of a cell can lead to consuming the energy produced by the rest of the system. The dissipation of this energy can lead to dangerous overheating and affect the cell. -
Page 13: Warnings And Electrical Risks
INSTALLATION MANUAL – 2012 WARNINGS AND ELECTRICAL RISKS • Each Module produces a direct current (DC) when it is exposed to sunlight or other light sources. Contact with any of the electrically active parts of the module, such as terminals, can result in injury or death, regardless of whether or not the module is connected. - Page 14 • The photovoltaic solar module has been designed to work with levels of incidental irradiance normally found on the Earth´s surface. DO NOT concentrate the radiation without the express consent of Helios Solar Works as this concentration without rigorous and uniform control can produce malfunctions and can affect some cells of the module.

UL regulation. As a result, when installing within North America: 6T series module can be connected to each other in groups of up to 13.* 7T2 series module can be connected to each other in groups of up to 11.* 9T6 series module can be connected to each other in groups of up to 8.*... -
Page 16: Module Wirings
INSTALLATION MANUAL – 2012 Module Wirings • The wiring must ensure that the loss of nominal potential is ~1% and no more greater than 2% •The recommended rating for wiring connections is 6mm and never less than 4mm , (10 AWG recommended and never less than 12 AWG). - Page 17 INSTALLATION MANUAL – 2012 Reliable Ventilation Sufficient clearance between the module frame and the mounting surface is required to allow cooling air to circulate around the back of the module. The clearance should also allow any resulting condensation or moisture to dissipate. The solar module should be assembled in the best possible orientation (South) and kept free from shadows, including partial shadows, to be able to obtain a good performance.
- Page 18 INSTALLATION MANUAL – 2012 • When installing the modules, please ensure the assembly is mounted over a fire resistant roof covering rated for the application and required a slope less than 5in/ft (127 mm/305 mm) to maintain a fire class rating.

Page 19: Installation Requirements
INSTALLATION MANUAL – 2012 Installation Requirements • Ensure that the modules meet technical requirements of the PV system as designed. • Ensure that other system components do not exert damaging mechanical or electrical influence on the modules. • Modules can be wired in series to increase voltage or in parallel to increase current. To connect in series, connect cables from the positive terminal of one module to the negative terminal of the following one. -
Page 20: Grounding
INSTALLATION MANUAL – 2012 Grounding The modules are certified double insulated, however it is recommended that they be grounded. In U.S. and Canada only: all PV modules must be grounded by electrical connection from the module frames to the ground. A UL-listed grounding lug should be used. Ensure compliance with all local electrical codes and regulations. - Page 21 INSTALLATION MANUAL – 2012 Metal containing iron in the conductive connection should be treated against corrosion by anodization, spray-painting, or galvanization to prevent rusting and corrosion. Another method is to ground the frame of the module to racking structure in accordance with NEC requirements for grounding solar electrical systems.
- Page 22 INSTALLATION MANUAL – 2012 At least one WEEBlug assembly should be installed on each rail (more if rail splices are used). Slide a bolt in the mounting slot of rail to the desired position, and then place the special steel flat washer on the bolt, orient so the dimples will contact the aluminum rail.

Page 23: Mounting Instructions
NOTE: Do not drill any additional holes in the module’s frame. Doing so will void its warranty. Comply with all local building codes. Helios Solar Works modules can be mounted on a roof: freestanding modules turn a class B rooftop into a class C rooftop. -
Page 24: Maintenance
INSTALLATION MANUAL – 2012 MAINTENANCE • Cleaning the modules improves their optimal performance. The cleaning should always be done using clean water with low calcium concentration and without detergents or abrasives. The water should not be applied at high pressure and scrapers or other cleaning tools should not be used as they may cause scratches on the glass. -
Page 25: Diagnostics And Troubleshooting
INSTALLATION MANUAL – 2012 DIAGNOSTICS AND TROUBLESHOOTING The strict quality controls in the factory ensure that Helios Solar Works modules are sold free of defects, breakages and/or other problems. However, in its operation some problems may arise that can alter the correct operation of the modules. - Page 26 INSTALLATION MANUAL – 2012 It is the owner’s and operator’s responsibility to determine and follow all national and local codes and regulations related to the use and installation of photovoltaic modules HUSA-EN-UL-REV 2.0 APR 16 2012...
