  Placement of modules
  The modules should be placed in a well-ventilated location where thereis no chanceof being shaded or immersed in water. The recommended ambient temperature for solar panel is 10 ° C ~ 50 ° C, with humidity range from 0 to 90%. Make sure the potential wind and snow load does not pass the maximum load tolerance of the modules, which are 2400Pa and 5400Pa respectively.
  Positioning
  The solar array generate maximum amount of energy output when the angle of the sun is perpendicular to the solar array. Since the actual optimal angle of positioning the solar array varies due to the earth’srotation and revolution, it is advised that to tilt the solar array up for30-45 degree from the earth, which is a well-balanced solution when using without a solar tracker. Regarding the facing of the solar array, a general rule is that to face towards south if the panel is in northern hemisphere and vise verse. At last, a clearance of at least 115mm(4.5in) should be provided between the panel frame and the object or wall behind.
  Electrical Characteristics
  The voltage system of the solar panel is divided into 12V and 24V, and solar panels of the same specification can be connected in series or in parallel.The electrical performance parameters of the modules such as Isc, Voc and Pmax are nominally ±3% error under standard test conditions. When the modules are connected in series, the final voltage is the sum of the individual modules, when the modules are connected in parallel, the final current is the sum of the individual modules.

The configuration of the battery needs to be based on the power of the solar panel.  Note that the positive pole is connected to the positive pole and the negative pole is connected to the negative pole.

• *12V &24V
  System Voltage: Normally we define solar system voltage based on battery voltage.  For example: If the system is for the 12VDC battery, we call it a 12Vsolar system; If the system is for the 24VDC battery, we call it a 24V solar system. ECO-WORTHY solar panel system is made up by solar panels of the power rate above 100W.The solar panels can be connected in series or in parallel to get the suitable voltage for the battery.

• *Wiring
  ECO-WORTHY recommends that all wiring be double insulated. All wiring should use flexible copper (Cu) conductors. It is recommended that you prepare the following devices by yourself before installing solar panels.

Step 2:
The panel ports of the controller are connected to the solar panel. Note that the positive pole is connected to the positive pole and the negative pole is connected to the negative pole. When the solar panel is normally powered, the indicator light on the controller will be bright. PS: The operating current of the controller should be higher than the output current of the solar system.

Step 3:
The load ports of the controller is connected to the DC load. -Reliable Solar Expert-

8.2 Testing The Solar Panel 1)Open Circuit Voltage (VOC)
IMPORTANT:
· Make sure the multimeter measurement function is set to measure DC Volts and the test leads are connected to the correct port, which in this case are Volt and COM.If the meter reads OL (overload) during this measurement, it means that meter must be set to a higher DC measurement range. Typical DC measurement ranges on the meters are (1) 0-20 VDC (2) 20-200 VDC (3) Above 200VDC. It depends on the Open-Circuit Voltage (Voc). For this module, the meter volt measurement range should be setto 20-200VDC. · Disconnect the solar panel completely from the battery and regulator. · While the solar panel is under the sunlight, measure the voltage by having the negative (COM) test lead that has been connected to the multimeter contacting the metallic part of the negative MC4 connector, and the positive test lead contacting the metallic part of the positive MC4 connector. If the reading on the multimeter is zero, then the junction box on the back of the solar panel should be opened with a flat-head screw driver so the measurement can betaken directly from the positive and negative terminals inside the junction box

SHORT CIRCUIT CURRENT (ISC)
· IMPORTANT: Make sure the multimeter selection is set to measure DC Amps, and the test leads are in the correct port to measure DC Amps. The range of measurement should be set to ~10A.

•  Disconnect the solar panel completely from the battery and regulator.

•  While the solar panel is under the sunlight, measure the amps directly at the positive and negativeMC4 connectors by having the negative (COM) test lead of the multimeter contacting to the metallic part of the negative MC4connector and the positive test lead contacting the positive MC4 connector.
  Cleaning and Maintenance

•  Do not scrub solar module with hard objects, scratched solar module glass surface lowers the conversion efficiency of the solar panel.

•  Cleaning of the solar array must be done thoroughly, leaving no place neglected or it may accelerate the aging of the solar cells or cause fire.
  3.It is recommended to perform a preventive inspection every six months by qualified personnel without changing the components of the modules.
  Cleaning Guideline:

• Disconnect the wire connecting the solar panel to other objects.

• Do not clean the glass with cold water while it is still hot to avoid thermal shock, which may shatter the module glass.

• Only use non-abrasive material such as a sponge or soft clothing to clean the glass surface of the assembly. Do not use hard objects to scrape the glass.

• Only use clean water for cleaning.Do not use chemicals.

• The temperature difference between water used for cleaning and the module should be limited to the range of -5 °C to +10 °C. 6.The pressure of the water used for cleaning should be less than 1000 Pa.
