9,49 kWp system in Cologne

In this system, we have installed a PV output of 9.49 kWp, as well as a 10.2 kWh battery storage and an intelligent wallbox.

The system is divided into two strings and two MPPT. The modules parallel to the roof have a slope of 30 ° and an orientation to the northeast (299 °). The elevated modules have an inclination of 15 ° and an orientation to the southwest (208 °).  All modules are combined with performance optimizers for the purpose of increasing yield, monitoring and security aspects.

​

The calculated energy yield is approx. 8,000 kWh per year, amortization is achieved after approx. 14 years.  

 

Components:
