Page 3: Introduction
JA Solar Modules. This Manual also contains safety information you need to be familiar with. All the information described in this Manual is the intellectual property of JA Solar and is based on the technologies and experience that have been acquired and accumulated by JA Solar. -
Page 4: Conventional Safety
3.2 Conventional Safety JA Solar Modules are designed to meet the requirements of IEC 61215 and IEC 61730, application class A. Modules rated for use in this application class may be used in system operating at greater than 50V DC or 240W, where general contact access is anticipated. -
Page 5: Operating Safety
3.4 Operating Safety Do not open the package of JA Solar modules until they are ready to be installed during transportation and storing. At the same time please protect the package against exposure to damage. Secure pallets from falling over. -
Page 6: Fire Safety
3.5 Fire Safety Consult your local authority for guidelines and requirements for building or structural fire safety. JA solar modules have been tested in according with IEC 61730-2 standard. The fire safety of JA modules is Class C. -
Page 7: Tilt Angle Selection
JA Solar Modules can be installed at seaside locations 50m to 500m from the sea, but the components should be protected against corrosion. -
Page 8: Installation Methods
Modules can be installed to the racks by clamps or hooks. Modules must be installed according to the following examples and recommendation. If not mounting the Modules according to these instructions, please in advance consult JA Solar and must be approved by JA solar, otherwise may damage Modules and void the warranty. - Page 9 Q/JASO-PMO-015 A/12 JA Solar PV Bifacial Double-glass Modules Installation Manual Clamp A The clamp used on the sided module (X=The height of module frame) Clamp B The clamp used on the middle module Figure 1 Mounting detail (Units: mm) 5.2.2 Modules installed with mounting hole Modules should be bolted to support structures through mounting holes located in the frame’s back flanges.

Page 12: Electrical Installation
Q/JASO-PMO-015 A/12 JA Solar PV Bifacial Double-glass Modules Installation Manual 6 Electrical Installation 6.1 Electrical Property Under normal conditions, the photovoltaic modules may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of short circuit current, Isc, and open circuit voltage, Voc, marked on modules should be multiplied by a factor of 1.25 when determining... -
Page 13: Cables And Wiring
(The maximum system voltage of JA Solar Modules is DC 1500V according to the safety appraisal of the IEC61730.) of the modules and all other electrical DC components will not be exceeded in open-circuit operation at the lowest temperature expected at the PV system location. -
Page 14: Bypass Diodes
6.4 Bypass Diodes The junction boxes used with JA Solar modules contain bypass diodes wired in parallel with the PV cell strings. In the case of partial shading, the diodes bypass the current generated by the non-shaded cells, thereby limiting modules heating and performance losses. -
Page 15: Grounding By Using Grounding Bolt
A/12 JA Solar PV Bifacial Double-glass Modules Installation Manual Please don’t drill any additional grounding hole on the frame of the modules, otherwise JA Solar expressly disclaim liability for voiding the warranty. To acquire the best power output, JA recommends clients to install modules with anti-PID inverter. -
Page 16: Additional Third-Party Grounding Devices
Figure 6: Installation methods 7.3 Additional third-party grounding devices JA Solar modules can be grounded using third party grounding devices so long as they are certified for grounding modules and the devices are installed according to the manufacturer’ s specified instructions... -
Page 17: Inspection Of The Connector And The Cable
Q/JASO-PMO-015 A/12 JA Solar PV Bifacial Double-glass Modules Installation Manual attention especially: A) Whether the glass is broken; B) Corrosion along the cells’ bus-bar. The corrosion is caused by the dampness infiltrated into the Modules when the surface encapsulation material is damaged during the installation or transportation.
