TE introduces new SOLARLOK automatic junction box

TE Connectivity ( TE ), formerly Tyco Electronics, introduced a new junction box for the photovoltaics family. This SOLARLOK automatic junction box is suitable for fully automated mass production, enabling crystalline silicon solar module manufacturers to significantly reduce assembly time and thus help reduce costs. Another advantage of this product is the increased reliability of the manufacturing process. In addition, this four-rail junction box has a range of intelligent features that can be operated using a robot.

Consistently high quality

In the current solar module manufacturing process, 98% of the junction box is still manually assembled to the back of the assembly. However, if this process is automated, PV module manufacturers can significantly reduce installation time and cost. Automated assembly of components is also more accurate than manual assembly and less prone to errors. In this way, the assembled solar modules can maintain consistently high quality.

Manual assembly possibilities

This new product also attracts manufacturers who are not yet fully automated, but are considering converting. The SOLARLOK automatic junction box is flexible enough to meet the needs of the customer and is used for manual assembly during the transition to its automated production line.

Simple and fast instantaneous high voltage test

Currently, transient high pressure tests used to test the performance of solar modules are typically performed manually. This automatic junction box allows this process to be done by the robot. The terminals are manufactured using two specially designed test points to avoid cumbersome manual cable connections. This not only saves time, but also increases the reliability of the test.

Unique terminal protection

The quality of the connection has a significant impact on the performance and service life of the photovoltaic system. From the processing to the final assembly, the plug terminals of the SOLARLOK automatic junction box are protected from dust and rain. This product therefore provides the most secure wiring match, and this comprehensive connection protection is unmatched by any other crimp-type automatic junction box.

Eliminate cable looseness

The standard coiled cable of the SOLARLOK automatic junction box ensures that all parts are in place and is ideal for assembly by robots.

New design prevents improper use

The product uses a simple yet clever design: the cable connections are all mounted at a 45 degree angle. In this way, the SOLARLOK automatic junction box prevents the installer from pulling the component by dragging the cable. The cables and plugs are thus kept intact and there are no problems caused by improper operation. Component manufacturers, installers and consumers all benefit from it – the solar system is up and running, and the complaint rate is falling.

Excellent quality comes from deep experience

TE has more than 25 years of experience in the solar industry. In addition, the company has used its decades of international experience in other industries for the solar business, giving SOLARLOK products exceptional reliability, robustness and durability.

The SOLARLOK automatic junction box complies with UL and IEC standards (IEC 61215 ed.2, certification is under review). TE offers two junction boxes for crystalline silicon components: crimped versions and soldered versions. The SOLARLOK automatic junction box will be unveiled at the Intersolar in Munich, Germany from June 8th to 10th and will be available worldwide in July 2011.
