Hello, This time you will see 2 installations. a larger one with a power of 39kWp and a smaller one with a power of 5.5kWp. The mounting system in both cases is a trapezoidal bridge. But the execution in our case is much more precise. In every respect. the biggest problem with the smaller installation is the incorrect running of cables through the trapezoidal bridges. In addition, in one of the shots you can see that the screw does not hold the Obornicka sheet metal. I hope you understand the message and what this shows you for over a year will be accepted to some extent. How should photovoltaic installations be done when it comes to the roof part. Sometimes it is worth making the installation so that it has the possibility of expansion, so as not to do the same work twice... *************************************** Every person who has watched the videos on @RoliWork knows one thing - accuracy is our determinant. Taking the first video you see, you can see in the execution itself. ***************************************** Social Media ****************************************** / roliwork / roliwork ***************************************** Contact ***************************************** Contact: [email protected] ***************************************** #photovoltaics #DIY #heatpump #buffer #tykajacababa #trapezoidalbridge
