Overview

• Klosterpark Altzella has become the first of Saxony's 19 Schlösserverbund sites to adopt photovoltaic technology, producing its own sustainable electricity.
• A €1.9 million upgrade installed 156 solar modules with a 69.4 kWp capacity and an air-water heat pump, replacing the old oil and LPG heating systems.
• The retrofit reduces CO₂ emissions by 25 tons annually and cuts public-grid electricity reliance by approximately 40 percent.
• The project adheres to strict monument protection requirements, balancing heritage preservation with modern energy solutions.
• As a pilot project, Altzella's success informs ongoing efforts, with a similar system already under construction at Dresden's Großer Garten.
