Sharp Launches the Industry’s Most Efficient 48-Cell PV Solar Module

Available with IEC certification (IEC/EN 61215 and IEC/EN 61730), the NQ-R256A solar module from Sharp is best suited for residential rooftops.

Sharp has launched the industry’s most efficient 48 cell solar module for the European market, following its best-selling success in Japan. With an award-winning design, the NQ-R256A (256W) mono-crystalline photovoltaic (PV) solar module incorporates Sharp’s back contact technology for unparalleled efficiency of 19.8%; increasing the amount of sunlight that can be used and returning maximum power output for minimum roof space.

With conventional technology the solar cells have the electrical contact wires on the front side, blocking the sunlight that enters into the cell, and approximately 6% of received light remains unused. With back contact cells all connectivity is removed from the front to the backside. Sharp’s back contact technology reduces the losses from 6% to 3%, an improvement of 50%. In addition to increased solar module efficiency the cell design also has a stylish black front.

The back contact solar modules are ideal for all family houses, whether small or large because any available roof space can be used more efficiently. On the same surface, the 48 cell modules can generate more power than with conventional 60-cell modules. The compact and lightweight 48 cell module is easy to handle, and can be installed either in portrait or landscape orientation.

The safety, quality and durability of the solar module have been recognized with IEC seals (IEC/EN 61215 and IEC/EN 61730). The module has a frame with two additional support bars and successfully passed a snow load test of 5400Pa according to IEC61215. Furthermore the module has received the most prestigious design award in Japan, the “Good Design Award”, which recognizes innovative products that have the potential to enrich life and drive industrial growth.

In addition to official tests, Sharp has developed its own sophisticated test procedure, which in important areas is more stringent than the IEC requirements. For example, the temperature test is carried out with 2,000 cycles, instead of only 200 cycles.

For maximum longevity of the whole system the junction box is protected against contact damage, overheating and water with fixed cable connections, heat sinks and resin filling. The NQ-R256A module is available for purchase in European market.
