Safety Precautions
Before installing the modules, read all safety instructions in this document.
- Modules produce direct current (DC) when exposed to light. Direct current can arc across gaps and may cause injury or death if improper connection or disconnection is made, or if contact is made with exposed leads. Do not connect or disconnect modules when current from the modules or an external source is present.
- Do not operate the modules in a short circuit condition for extended periods of time.
- Do not artificially expose additional high intensity sunlight directly on the module.
- Do not disconnect modules while under load.
- All installations must be performed in compliance with local, regional, national and international statutory regulations, guidelines, norms and code requirements.
- For projects in Canada, the installations shall be performed in accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
- There are no user serviceable parts within the module. Do not attempt to repair any part of the module.
- Installation should be performed by authorized personnel only.
- Use insulated tools to reduce risk of electric shock. Do not touch terminals with bare hands.
- Use heavy duty gloves to reduce risk of injury from sharp edges or corners.
- Do not stand on, drop, or allow objects to fall on modules.
- Do not install or handle modules when they are wet or during periods of high wind.
- Before installing your system, contact local authorities to determine necessary permit, installation and inspection requirements.
- Module support structures should be snow and wind load rated per local code and approved for use by the local authorities.
- The solar system, its components, and installation should be approved by the authorities having jurisdiction in the area.
FIRE RATING AND SAFETY
- PowerXT R-PD, R-PM, and R-PL residential solar modules are UL 61730 fire type 1 rated and IEC 61730 application class II. The solar modules have been certified by an independent third-party testing laboratory.
- Refer to your local authority for guidelines and requirements for building or structural fire safety.
- The roof construction and installation may affect the fire safety of a building: improper installation may contribute to hazards in the event of fire.
- It may be necessary to use components such as earth fault circuit breakers, fuses and circuit breakers.
- Do not use modules near equipment or locations where flammable gases can be generated or can collect.
Artificially concentrated sunlight shall not be directed onto the module.
ELECTRICAL INSTALLATION
Caution : Avoid all electrical hazards when installing, wiring, operating, and maintaining a module or module array. Refer to Section 2 for more information
- The system must be installed, commissioned and maintained by a licensed electrician unless local electrical codes determine otherwise.
- Contact with DC voltage is potentially hazardous.
- Do not use modules of different electrical or physical configurations in the same DC string or inverter.
- For field connections, Solaria recommends that all connecting cables be double insulated flexible copper (Cu) conductors with a minimum rating of 90°C. The cable size should be determined by the applicable codes but is recommended that this be no less than 4mm² or 12AWG. The connectors must be compatible with the factory installed connectors on Solaria panels (MC4 design) or as specified in the product datasheet.
- Series Connection: The modules may be wired in series to produce the desired voltage output. Do not exceed the maximum system voltage indicated on the module label.
- Parallel Connection: The modules may be combined in parallel to produce the desired current output provided that each series string or module is fused prior to combining with other strings. The maximum fuse size allowed is noted on the module label.
- Connection cables and wiring shall be supported with plastic or rubber cable ties and clips to the module support structures. Metal clips specifically designed to be used in solar applications are allowed when used in accordance with the manufacturer’s instructions. Module junction boxes and metal cable ties should not be used to support cables and wiring.
- Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at Standard Test Conditions (STC). The requirements of the National Electrical Code (NEC) shall be followed to address these increased outputs. In installations not under the requirements of the NEC, the values of Isc and Voc marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor capacities, fuse sizes, and size of controls connected to the PV output.
- Refer to the NEC for additional multiplying factors that may be applicable.
- All Solaria modules are equipped with connecting cables and locking connectors. Modules have been designed to be easily connected. The locking connectors are not to be disconnected under load. The proper procedure to disconnect the module locking connectors is as follows: Turn off the inverter(s), shut off the module DC disconnect(s) and then disconnect the locking connectors using an approved tool set. To re-install, connect the module locking connectors, turn on the module DC disconnect(s) and turn on the inverter(s).
- Match the polarities of the cables and terminals when making connections; failure to do so may result in damage to the modules and other electrical equipment.
- A properly rated and certified over-current device must be connected in series with each module or string of modules when reverse currents can exceed the value of the maximum protective fused value noted on the module label. The rating of the over-current device shall not exceed the value of the maximum protective fuse rating specified on the module label.
- All Solaria modules are factory supplied with bypass diodes located in the junction box.
- The junction box is not designed or certified to be field accessible or maintainable and should under no circumstances be opened. Opening the junction box may void the module warranty.
Grounding (Grid-tied applications)
-
Before installing the solar system, contact local authorities to determine the necessary system hardware grounding requirements.
-
Module frames should be electrically connected to an earth ground for safety and protection from lightning in accordance to the National Electric Code (NEC).
-
PowerXT® residential solar modules may be installed on a mounting system certified to UL 2703 with approval of the mounting system manufacturer.
-
When using a mounting system, grounding of modules must be accomplished by the method prescribed by the mounting system manufacturer.
-
Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers and the like) are used to attach the solar module to a listed grounding/bonding device, the attachment must be made in conformance with the grounding device manufacturer’s instructions.
-
Common hardware items such as nuts, bolts, star washers, lock washers, and the like have not been evaluated for electrical conductivity or for use as grounding devices and should be used only for maintaining mechanical connections and holding electrical grounding devices in the proper position
for electrical conductivity. Such devices, were supplied with the module and evaluated through the requirements in IEC/UL 61730, may be used for grounding connections in accordance with the instructions provided with the module. -
Follow these instructions to ground the module.
-
The module frame has four 4.5 mm grounding holes (‘A’) that are shown on the module drawing. Attach
a 10 AWG (2.588 mm diameter) bare copper ground conductor to a grounding lay- in lug mounted at one of the four grounding holes on the module frame. Use a grounding lug with tin plating and stainless-steel hardware (#10-32 hex head screw at 4 mm diameter, flat washers, tooth lock washer and nut). -
A #10 flat washer must be used between the screw head and the grounding lug to prevent damage to the tin plating on the lug. Insert a #10 flat washer between the grounding lug and the module frame. A #10 tooth lock washer must be inserted between the nut and the module frame to break the anodized layer of the frame. This mechanical bond between the tooth lock washer and the frame of the module will ensure a good electrical bonding path.
-
The #10-32 assembly attachment screw must be tightened between 20-25 inch-pound. A 10 AWG bare copper ground conductor must be attached to the ground lug using the stainless-steel set screw provided by the lug manufacturer. Tighten the set screw between 10-15 inch-pound to ensure a strong mechanical and electrical bond.
-
Recommended stainless steel hardware and assembly:
Non-Grid-Tied Applications
- Contact Solaria for appropriate grounding guidelines.
