Compatibility of PV-Connectors

Connectors advertised by third-party supplier as "MC compatible" must not be mated with MC connectors for safety reason! Stäubli Electrical Connectors will not accept any responsability for damages caused by the mating of MC components with foreign products that have not explicitly been approved by Stäubli Electrical Connectors.

What is the MULTILAM Technology?

Among the countless types of electrical connectors from signal currents up to extremely high currents, MULTILAM stand out on the strength of excellent performance. The MULTILAM, cornerstone of MC contact technology, has virtually unlimited applications due to its design flexibility and advanced features.

What sort of testing do you carry out on your connectors to ensure their long lifetimes?

Please undestand that I cannot reveal any details at this point. But I can tell you that in addition to the mandatory tests required by IEC (EN 50521 und EN 50548) and UL (1703 und 6703) we run various internal tests to support and confirm our statements concerning long-term stability. Stäubli Electrical Connectors can resort to know-how bult over 50 years, especially in fields that demand highest quality, safety and longevity. Our particular strenth is a benefit for the PV industry, where environmental conditions challenge every single component over a time period of 20 or 30 years of operation. Most of our customers are convinced that savings would have been made at the wrong end if the connectors became untight or their electrical resistance rose over time.

What is a PV panel?

A PV solar panel, referred to in the industry as a solar module, is constructed by connecting photovoltaic cells (or PV cells) to produce electricity. The cells are a semiconductor-based technology that converts solar radiation into direct current (DC) electricity. Solar panels for grid-connected home or business use typically use 60 or 72 PV cells.

What are Monocyrstalline Panels?

These are made from cells created by cutting thin slices from single crystal silicon block and are higher in efficiency, but also higher in cost per watt. They are easy to spot because they have a smooth even color, usually black.

What are Polycrystalline Panels?

These are made from cells created by cutting thin slices from polycrystal silicon block and are slightly lower in efficiency, but also lower in cost per watt. Polycyrstal silicon is the "chicken nugget" of silicon, made by combining many individual crystals. They are easy to spot because they have an uneven color, usually blue.

What are Thin film Panels?

These are made by depositing a thin layer of very finely powdered silicon (amorphous silicon) or other photovoltaic material, on a substrate. These are much lower in efficiency that crystalline cells, and somewhat cheaper per watt. They are a good choice for large ground mounted utility scale solar arrays where real estate is plentiful. Their low efficiency makes them undesirable for commercial and residential applications because they consume a large amount of roof space compared to mono or poly panels.

What are solar inverters?

An inverter is any device that inverts DC (direct current) into AC (alternating current). In a solar installation, an inverter is a centralized device that connects to and manages the performance of the solar panel array; it aggregates the DC power coming from the panels or strings of panels and inverts the DC power into single phase (or three phase) AC power at the correct voltage for delivery into the users electrical system, and provides equipment protection and safety features. The better inverters on the market also allow for data logging and web-based remote monitoring of important performance metrics and power generation.
