Overview

• The new Photovoltaik-Strategie aims for 500–800 MWp of installed capacity by 2030 and 1–1.5 GWp by 2035.
• Hamburg’s current base is about 230–234 MWp, underscoring the scale of the required expansion.
• At least 80% of suitable public-building roofs are to be equipped with solar by 2030 where feasible.
• The CDU calls the plan inadequate, citing roughly three percent of buildings with PV and proposing competitive leasing of public roofs to private providers.
• A 884‑module system on the Congress Center Hamburg, spanning about 1,760 m² and generating over 318,000 kWh annually, is showcased as a model alongside options like façade PV, parking canopies and agri‑PV.
