Solar panels have become cheaper and well-organized in recent years, but they are far away from a universal solution, even in sunny regions due to a typical solar photovoltaic (PV) installation is still beyond the budget of many people and a second obstacle for solar power is that not everybody lives in a single-family dwelling with access to a private roof.

With the help of the solar panel installed in the apartments we are able to reduce the source of energy which is used to heating, cooling and hot water for apartment building.  To make the apartment to sustain due to energy-efficient in residential environment is the important goal for the future. Due to the increase in the price of the energy, we are driving force behind finding new solutions that allow our building to become more self-sufficient in terms of energy.
