IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions for the PV module
that must be followed during the maintenance of PV modules.
To reduce the risk of electric shock, do not perform any servicing
unless you are qualified to do so.
1. The installation must be performed by a certified installer
/servicer to ensure system integrity and safety.
2. The installation is only allowed after referring and
understanding of this INSTALLATION MANUAL. If you don’t
have your personal copy, please contact your installer or local
SHARP office listed in SHARP Solar web site:
https://www.sharp.eu/
3. Do not pull the PV cables.
4. Do not touch any surface of PV module.
5. Do not place/drop objects onto the PV modules.
6. Do not disassemble or attempt to repair the PV module by
yourself.
7. Do not drop the PV module.
8. Do not damage, pull, bend, or place heavy material on cables.
9. Upon completion of any service or repairs, ask the
installer/servicer to perform routine checks to determine that
the PV modules are in safe and proper operating condition.
10. When replacement parts are required, be sure the
installer/servicer uses parts specified by the manufacturer with
same characteristics as the original parts. Unauthorized
substitutions may result in fire, electric shock, or other hazard.
11. Consult your local building and safety department for required
permits and applicable regulations.
12. As a result of sliding snow, the mechanical load increases when
the number of PV module rows in the matrix of a PV installation
increases. When mounting the PV module in the portrait
orientation for more than 3 rows, the accumulated snow load
may cause the lower edge of the PV module frame to deform.
Take necessary measures (e.g. snow stopper) to avoid
possible damage.
13. Periodically remove any overhanging snow and/or ice from the
PV module framework as it may cause deformation of the PV
module frame.

This document is an installation manual for a Crystalline Photovoltaic Module, specifically the SHARP model NU-JC415. It provides essential information for the electrical and mechanical installation, as well as safety guidelines for handling and maintaining the PV modules.

Function Description

The SHARP NU-JC415 is a Crystalline Photovoltaic Module designed to convert sunlight into electricity. These modules can be wired in series to increase voltage or in parallel to increase current, forming a larger PV system. They are equipped with permanently attached junction boxes that facilitate various wiring applications. The modules are designed to operate effectively in an environmental temperature range of -40 °C to +40 °C and up to 100% relative humidity, and at altitudes up to 2,000 m. They are classified as "Class II" for protection against electric shock and rated as "Fire safety class C."

Usage Features

Installation: The installation of these PV modules requires a high degree of skill and should only be performed by qualified, licensed professionals. Before installation, it is crucial to consult local codes and laws for required permits and regulations. The modules should be installed and maintained by qualified personnel, with access to the installation site restricted to installer/servicer personnel.

For optimal performance, PV modules should be installed in a location free from shading throughout the year. In the Northern Hemisphere, modules typically face south, and in the Southern Hemisphere, they typically face north. The tilt angle, measured between the PV module and a horizontal ground surface, is critical for maximizing output power. For standalone systems with a battery, the tilt angle should be chosen to optimize performance when sunlight is scarcest. For grid-connected installations, tilting the module at an angle equal to the latitude of the installation site is recommended for optimum power generation throughout the year. A tilt angle of 5 degrees or more is recommended for maintenance purposes.

The modules can be mounted using clamps or bolts. When using clamps, they must meet specified dimensions and hold the module frame completely within its width. The clamp center position is critical to prevent serious deflection and cell cracks. When mounting with bolts, four M8 bolts are recommended, with a torque of 12.5 Nm. The mounting method must ensure the PV module is fixed rigidly without damage to the module or the mounting structure. The support structure must be rigid, allowing the PV module to deflect freely under wind and/or snow load without direct impact to the center of the module.

Wiring and Grounding: Correct cable connection polarity is essential for proper system operation and to maintain the warranty. PV modules can be connected in series (positive to negative) to increase voltage or in parallel (positive to positive) to increase current. Bypass diodes are built into the junction box. For parallel connections, specific options involving diodes or fuses per string are outlined to protect against reverse current overloads. The frame grounding must comply with local requirements and regulations. An example connection using a bolt, nut, and washer is provided, ensuring electrical contact with the frame. The ground wire must also meet local requirements.

Safety Precautions during Use:

• Avoid excessive loads on the PV module surface or twisting the frame, as this can break the glass or cells.
• Do not stand or step on the module, as the surface can be slippery, and the weight may cause damage.
• Do not hit or apply excessive load to the glass or back sheet, as the PV cell is very thin and easily broken.
• Do not scratch or hit the back sheet, as it is vulnerable.
• Do not damage the junction boxes or pull the cables, as they can crack or break.
• Never touch the junction box or output cable ends with bare hands when the module is irradiated. Cover the module surface with an opaque material and wear rubber gloves to avoid electric shock.
• Do not scratch or bend the output cable with force, as insulation can break, leading to electricity leakage or shock.
• Do not drill holes in the frame, as it compromises strength and causes corrosion.
• Do not scratch the insulation coating of the frame (except for grounding connection), as it can cause corrosion or compromise framework strength.
• Do not touch the PV module with bare hands, as the frame has sharp edges that can cause injury.
• Do not drop the PV module or allow objects to fall on it.
• Do not concentrate sunlight artificially on the PV module.
• Do not hold the PV module on one side; hold it at opposite sides to prevent bending or twisting.
• Do not shade portions of the PV module surface for long periods, as this can cause hot spots and damage.
• Do not install the PV module horizontally, as this can lead to dirt or white efflorescence due to water accumulation.
• Do not cover the water drain gap of the frame, as this can cause frost damage.
• If there is a risk of sliding snow, take measures to protect the lower edge of PV module frames from damage.
• Turn off inverters and circuit breakers immediately if a problem occurs.
• If the glass surface is broken, wear safety goggles and tape the glass to contain broken pieces.
• A defective PV module can still generate power; place it in a carton to completely shade the cells.
• Keep PV modules away from children.

Maintenance Features

The PV modules are designed for a long life and require very little maintenance.

• Cleaning: If the PV module angle is 5 degrees or more, normal rainfall is usually sufficient to keep the glass surface clean. If dirt buildup becomes excessive, use only a soft, damp cloth and water to clean the glass. Avoid using chemicals to clean the glass surface. Do not let water collect on the glass surface for long periods, as this can lead to white efflorescence (glass disease) and deterioration of energy generation. The PV modules are equipped with anti-reflective coating glass; avoid touching the glass to prevent fingerprints or stains.
• Inspection: Periodically check the connection of wiring and the state of the wire jackets to ensure proper system operation.
• Snow and Ice: Periodically remove any overhanging snow and/or ice from the PV module framework, as accumulation can cause deformation of the frame.
• Disposal: Dispose of PV modules properly. Contact your local recycling site for information on proper disposal.
