After the expansion of photovoltaics plummeted in 2012, it has been steadily increasing again for several years. After wind power, photovoltaics is the second most important renewable source of electricity in Germany.

The structure of a PV system can be divided into electricity generation and electricity use. The photoelectric effect in the solar cells produces direct current, which is generated by the modules and transmitted to the inverter via solar cables. The inverter is the heart between the solar modules and the power grid. In addition to converting direct current into alternating current, it is also responsible for monitoring and optimizing performance.

In the inverters of well-known manufacturers, the PERFECT cable glands made by JACOB ensure that the cables are inserted securely and tightly.

In addition, there are many more of Jacob's products in photovoltaic systems: venting elements, screw plugs and other accessories.

Made from high-quality, black polyamide PA6, they are UV-resistant, weather-resistant and have excellent longevity. Ideal for all applications - outside and inside. With a wide operating temperature range and high protection grades, they defy hot and cold conditions, moisture and dust.
