5.2.4.3
Please visit http://www.jolywood.cn/ to view the “Product Catalog” link for detailed grounding holes locations and dimensions.
5.2.4.4
The electrical contact is formed by penetrating the anodized coating of the aluminum frame and tightening the ground screw (together with the star washer) to an appropriate torque of 3~7N.m. A properly sized ground wire (4-16mm2 copper core wire) should be selected and mounted under the connecting bolt.

Place the toothed washers, washers, and grounding wires in turn, and screw the screws into the grounding holes to connect the two adjacent modules.
5.2.5 Electrical Installation
All wiring should be performed by a qualified and trained person in accordance with local regulations and procedures. Modules could be connected in series to increase the operating voltage by inserting the positive plug of one module into the negative plug of another module. Always ensure that the contact points are corrosion-resistant, clean, and dry before wiring modules. If the polarities of modules are connected wrong may lead to irreparable damage. Before modules are connected in parallel, please check the voltage and polarity of each module array. If the polarity of products is opposite or the Voltage difference greater than 10V is found after measurement, please check the configuration of the module array before its access to power grids.
All cables and connectors used to connect the DC system must have a similar (or higher) level. It is suggested that all cables should run in proper cable ducts and should be located away from the water-prone area.
Each module has two standard 90°C shading output cables with a plug-and-play connector on each terminal. Jolywood modules are equipped with a DC copper cable with a cross-sectional area of 4mm2, system voltage 1500V DC, insulation layer maximum work temperature up to 90°C, also UV-resistant. All cables used to connect the DC system must have similar or high levels. It is required that all wiring and electrical connections should comply with the appropriate National Electrical Code.
The voltage of modules shall not be higher than the maximum voltage borne by the system, and factors such as the lowest expected temperature shall be considered. It is recommended to calculate according to the following formula: Maximum system voltage ≥ N x Voc x [1+ (Tcvoc x (Tmin-25)] Of which:
N represents the number of modules; Voc represents the open circuit voltage of the component; Tcvoc represents the temperature coefficient of the component’s open circuit voltage; Tmin represents the minimum ambient temperature;
5.2.6 Wiring
In order to ensure PV system could operate smoothly, when connecting modules or connecting loads (such as inverters batteries, etc.), ensure that the polarity of the cables is
properly connected (Figure 1 and Figure 2). If modules are not connected properly, the bypass diode may be damaged. Modules could be connected in series to increase voltage.
Connect modules in series by inserting the positive terminal of one module into the negative terminal of the next module. Figure 1 shows the serial connection of modules. Modules could be connected in parallel to increase the current (shown in Figure 2). Connect modules in series in Parallel by inserting the positive terminal of one module into the negative terminal of the next module. The number of modules connected in series or in parallel needs to be reasonably designed according to the system configuration.
All instructions above must be followed to meet the Jolywood Warranty valid conditions.

5.2.6.1 Fuse
The fuse should be connected to each non-grounded pole of the array (in other words, if the system is not grounded, the fuse should be connected to both positive and negative terminals).
a) The maximum rating of the fuse connected in series is 30A, and the module- specific ratings are available on the product label and product data sheet.
b) The fuse rating also corresponds to the maximum reverse current that the module could withstand (when an array is shading, the array is loaded into another parallel module array to generate power), thus the number of parallel connected arrays is affected.
c) It is forbidden to connect two or more strings in parallel and then share the fuses.

Maintenance for PV Modules

6.1 Module Visual Inspection and Replacement
Modules in array should be regularly inspected to check damage modules. If the damage module is founded, it must be replaced with the same type. Such as broken glass, broken cables, damaged junction boxes, etc., which would lead to functional and safety failure of modules. Well-designed solar systems require minimal maintenance, and some simple steps could be taken to improve system performance and reliability.
6.1.1
Maintenance should be carried out at least once a year by a trained person. As the system voltage is so high, the maintenance person should always wear rubber gloves and insulated boots. Removing all possible shading of the solar array, which would affect the power generation of the module array.
6.1.2
Check if the installed hardware is securely in place.
6.1.3
Check if all array fuses in each of the non-grounded poles are working properly.
6.1.4
If module is damaged (glass breakage or scratches on the back glass), it is need to be replaced. Module must be replaced with same type one. Do not touch the live parts of the cables or connectors when replacing modules. Use appropriate safety guards (insulation tools, insulated gloves, insulated boots, etc.) when handling modules.
6.1.5
Cover the front surface of Modules with an opaque material. Modules exposed under the sun could be extremely dangerous, as high voltages could be generated.
6.1.6
Module junction boxes is equipped with bypass diodes to minimize module heating and current loss.
6.2 Connector and Cable Inspection
6.2.1
Check if all cables are securely connected. It is suggested that all cables should run in proper cable ducts and should be located away from the water- prone area.
6.2.2
Check the electrical, grounding, and mechanical connections every 6 months to ensure that they are clean, safe, free from damage, and rust-free; ensure that the mountings properly tightened; check all cables to make sure they are tight.
6.2.3
It is forbidden to use WD-40 or various organic solvents to wipe all parts of the junction boxes, wires, and connectors.
6.2.4
The dustproof plug should not be removed in advance, it can only be removed during installation.
6.3 Cleaning

The amount of electricity produced by a solar module is proportional to the amount of light that reaches its surface of it. A dust-covered module produces relatively lower power, so it is important to keep module clean.
a) The PV module should be cleaned under an irradiance of less than 200W/m2. Avoiding cleaning water with great different temperatures from air to avoid cracking. Hard water needs to be softened. The water remains should be removed from the glass surface after cleaning.
b) It is strictly forbidden to clean PV modules under special weather: wind level greater than four, heavy rain or heavy snow.
c) During cleaning, the water pressure on the surface of the module glass shall not exceed 4MPa, and the module is not allowed to withstand additional external force.
d) During cleaning, it is strictly forbidden to step on the modules, splashing water to the back of the modules or cables. Ensure that connectors are clean and dry to prevent electric shock and fire hazards. Steam clean machines are strictly prohibited; soft parts, Cloth, mild detergent, and water should be used. Do not put modules directly into the water. Serious thermal shocks also could damage modules.
e) The difficult-to-clean substances such as oil on the surface of modules, use a non-friction neutral liquid cleaner. Do not use any organic solvent containing alkali or acid. Do not use corrosive solvents or wipe the PV modules with a hard object.
f) If you are not sure whether the array needs to clean, first select a column of the particularly dirty array to begin cleaning. If the power generated increased by less than 5%, cleaning is usually not required. The above verification should be carried out only under a stable sunshine rate (sunny, strong sunshine, no cloud).
g) The back of the PV module usually does not need to be cleaned; If you need to clean the back of the PV module, ensure that the cleaning liquid does not penetrate into the bottom layer of the material.
h) Regularly trim the vegetation to prevent shading created on the module surface, which would decrease power generation.
