Welcome to Connector Industry Insiders

Here, we’ll be talking about all things connectors. We’ll start this off with some information on solar connectors.

Solar power is increasing in use and popularity (unlike d-sub connectors). But the rise of solar power really started in 1880, when a team of scientists started to develop the technology behind it. Well, actually…the Sun has been a work in progress for billions of years. But it was only in the very recent history of humanity that we learned to harness it through something called the photoelectric effect.

The photoelectric effect is best described as a process by which electrons are emitted from solids, liquids, or gases as they absorb energy from light. To take flight, this effect needs many things, including solar cells, an inverter, and the electronics to capture it all. This includes connectors.

But why are solar connectors gaining so much in popularity along with solar power in general? For one, they are preferred to hardwired ones due to their increased efficiency and reduced installation costs. They are also designed to meet the strict demands of the connector industry, so you know they are reliable.

To be approved for the UL 6703A standard, a solar connector undergoes 3  tests:

  • an impact test, where a 2-inch steel ball is dropped on it under horribly cold conditions (-35 degrees Celsius)
  • a thermal cycling test, where the connector is exposed to the worst weather conditions imaginable
  • a humidity test, where it is subjected to 85% humidity

With their environmental benefits, reduced costs, and proven reliability, it is easy to see how solar connectors are the future of the connector industry.
