Here you can see a single-phase PV installation in Knyazhevo built on a bitumen roof. The max power output is 6kW. The plant was built with the purpose of helping meet the energy needs of the household and to provide an emergency power supply in case of need.

The plant includes 12 pieces of 505-watt photovoltaics with a 30-year performance warranty. All panels are situated on a South-facing slope of the house’s roof, which will allow them to be exposed to direct sunlight for the better part of the day.

The PV plant also includes batteries. Thanks to those, whenever the photovoltaics are providing more power than what the household currently needs, the excess is going to be stored. This charge can then be used at a later point when there is insufficient sunlight or the consumption goes up. Should there be interruptions of the power provided by the grid, the batteries also enable the plant to act as an emergency power supply.

The single-phase hybrid inverter is also accessible through a mobile app. Through this, the current state of the whole plant, as well as historical data regarding its behavior and performance, can be monitored from afar. This includes data regarding the power output of the installation, the state-of-charge of the batteries, the power usage, the ecological benefits of the PV plant and various other indicators. This information is not only interesting to read, but it can also be used to optimize the power usage of the household.

Here are some pictures from the process of setting up the installation.
