Tratos solar cables are specially designed cables intended for use with photovoltaic (PV) systems, which harness solar radiation to produce electricity. All solar power systems depend on these cables to connect solar panels to batteries, charge controllers, inverters, and the electrical grid. Expertly designed for solar installations, Tratos Solar cables are an essential part of renewable energy systems. These multipurpose cables work well for both indoor and outdoor applications and can be installed in conduits and ducts.

Using the photoelectric effect, photovoltaic solar energy converts sunlight into electrical power. It has substantial non-polluting advantages as a renewable, non-depleting energy source. There are several uses for photovoltaic technology, ranging from tiny self-consumption devices to massive photovoltaic plants or solar farms that produce significant amounts of electricity for larger communities.

In addition to producing power, photovoltaic systems play a critical role in worldwide efforts to reduce carbon emissions. They greatly contribute to the global aim of lowering carbon emissions and battling climate change, as well as minimising the ecological impact of typical fossil fuel energy generation.
