Installation of a solar system with bifacial photovoltaic modules of the 4kWp series:

Your 4 kWp series solar system is supplied with all the necessary accessories. Simply arrange for a specialist to install the system for you. As the solar system must be connected to the main distribution board, it is essential to entrust a professional with the task. However, you can install your modules on the roof yourself. If you do not have an electrician, it is also possible to use a partner from our pool. Get in touch with us and we will be happy to put you in touch with a reliable specialist. They will also ensure that the cabling is installed according to your needs and, above all, in a way that conserves resources. It is important to remain flexible, which is why the cabling is carried out on site and is not included in the scope of delivery. In this way, you help to save resources and money, as the cables are adapted to the right length on site and the specialist can react to all eventualities.

How do I optimally align the modules of my balcony power plant? 

​For the greatest possible energy yield, we recommend orienting the solar modules to the south at an angle of 30 - 40°. Orientation to the east or west generates slightly less electricity over the course of the day, but offers you the opportunity to achieve higher yields in the morning and evening, when the average electricity consumption in most households is at its highest. A north-facing orientation should be avoided due to the low solar radiation.

Are my solar modules weatherproof?

Yes, your solar modules are waterproof and designed for temperatures between -40°C and +85°C. The modules are optimally protected against rain, frost and moisture and can be used all year round without hesitation.
