Page 3: Introduction
If patent rights or the third party rights are infringed by use of modules, DualSun will not take any responsibility. DualSun reserves the rights for modifying product manual or installation manual without notice in advance. -
Page 4: Regular Safety
Figure 1Module Section Structure and Components Regular safety DualSun module is considered to be in compliance with IEC61730 only when the module is mounted in the manner specified by the mounting instructions below. When the module is installed on roof, it is necessary to take the overall fire rating of the finished structure as well as later overall maintenance into account. -
Page 5: Electric Performance Safety
Electric performance safety The application level of DualSun module is Application Class A , w hich can be used in systems operating at greater than 50 V DC or 240 W, where general contact access is anticipated; In case of no connected load or external circuits, modules can also produce voltage. Please use insulation tools and wear rubber gloves when operating modules in the sunlight. -
Page 6: Fire Safety
Please consult local laws and regulations before installing modules and abide by requirements on building fire protection. Fire rating of DualSun modules is Class C according to IEC 61730-2. The roof shall be coated with a layer of fireproof materials of such rating for roofing installation and make sure that the back plate and the mounting surface are fully ventilated. -
Page 7: Selection Of Tilt Angles
PV module installer. DualSun suggests that module installation tilt angle be no less than 10° so module surface dust can be washed away easily by rainfall and times of cleaning can be reduced. And it is easy for ponding to flow away and avoid water print on the glass due to long time of water ponding which may further affect module appearance and performance. -

Make sure that back plate of modules will not contact bracket into the module or building structures, especially when the module surface is imposed by pressure. DualSun Modules have been certified for a maximum design static load on the back of the Modules of up to33.4 lb/ft (i.e. - Page 9 Make sure that the clamp will not produce shading effect.
