Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts. [pdf]
The photovoltaic combiner box resists a wide range of temperatures, from- 22 degree Celsius to 55 degree Celsius. You can install the PV combiner box on rooftops or other areas where exposure to extreme weather conditions is every day. [pdf]

Power reduction of 21.47% is observed in glass to backsheet PV modules under hail. PV modules with front glass thickness of 4 mm can withstand severe hail damage. Use low wet-leakge current resistance modules for high hail-prone regions. [pdf]

Tempered glass can withstand greater impact of natural forces such as wind pressure, sand, hail, and large temperature difference between day and night, thereby effectively protecting solar cells from damage. [pdf]

The primary difference is that a non-isolated converter does not have a transformer and does not require any physical separation between input and output, so this typically makes them smaller and lighter. It also improves the efficiency as there are no transformer losses to take into consideration. [pdf]
