Product Description
(Our products are backed by an industry standard 5/10/25 warranty to assure the longevitiy of your system. Not only this, we assure the quality of our modules with 100% infrared scanning to go with our standard quality assurance procedures. )
Product description
Aesthetic appearance with excellent efficiency based on innovative
Cheap monocrystalline solar panel with photovoltaic technologies
Strong frame, passing mechanical load test of 5400PA, instead of the normal
2400PA, to withstand heavier snow load and higher wind-pressure
Builtin bypass diode inside the junction box, which could prevent the effects dark spots of local damage to cells.

Materials of solar panel:
1. Solar cell------ Germany manufactured Bosch solar cells, efficiency is about 18%
2. Front glass------ high transmission, low iron, tempered glass.
3. EVA------excellent anti-aging EVA
4. TPT-------TPT hot seal made of flame resistance, imported.
5. Frame------ Unique aluminium frame design with high mechanical strength for installation...
6. Junction box------ IP65 rated, high quality, with diode protection.

Sungold Solar Module bracket configuration:
The Solar module combines the Monocrystalline (polysilicon) solar cells in series, with a high current density and smaller size.
The solar panels are aluminum alloy frame, the former board and backplane.
From laminated packaging; Components on the metal frame has mounting holes, easy to use, and with the solid structure
3mm thick tempered glass front panel, it offered the high-performance protection for resisting the impact of environmental. And it has a high transmission rate of direct light and scattered light.250 Watt 30 Volt Solar Panel Making + Waterproof Junction Box RV Versatile Boat
