The city of Porvoo expanded its central kitchen solar power plant<\/a> with a 60 kWp roof-mounted system, implemented by Finnwind Oy. The site already had an approximately 10 kWp wall-mounted plant installed by Finnwind in 2017. The new system was completed and ready for use in late 2025 before the snow arrived. <\/p>\n\n

Mika S\u00f6derstr\u00f6m, construction manager for the city of Porvoo, explains that the city has long invested in energy efficiency, alternative energy solutions, and the utilization of solar power. <\/p>\n\n

\u201cWe have increased solar capacity at several sites. The central kitchen has a high base electricity load, so expanding solar energy capacity was a logical step,\u201d S\u00f6derstr\u00f6m says. <\/p>\n\n

The expansion utilized the same inverter types as the original system. <\/p>\n\n

\u201cWe wanted to keep consumption data and monitoring within a single cloud service. It makes maintenance and lifecycle management easier,\u201d S\u00f6derstr\u00f6m explains. <\/p>\n\n

Installation before winter \u2013 roof maintenance considered<\/strong><\/h3>\n\n

Before implementation, the load-bearing capacity of the roof structures was verified, and load calculations were completed prior to the tendering process. According to S\u00f6derstr\u00f6m, project preparations progressed professionally: plans, safety documentation, and site arrangements were delivered comprehensively, and responsibilities were clearly defined. The project proceeded on schedule without significant change orders. <\/p>\n\n

The panels were installed on a flat roof using concrete ballast mounting across two separate areas. The placement took into account the ventilation machinery room, roof access routes, and maintenance needs. <\/p>\n\n

\u201cIt is important that roof access remains easy for servicing ventilation pipes, eaves, and other structures,\u201d S\u00f6derstr\u00f6m notes. <\/p>\n\n

Documentation delivered on time \u2013 ready to generate for spring<\/strong><\/h3>\n\n

The handover documentation was delivered on schedule, and only minor finishing remarks were made during inspection. The old and new systems were successfully integrated into the same monitoring platform. <\/p>\n\n

The expansion was completed in winter, therefore comprehensive production data is not yet available. Sunny winter days at the beginning of the year have already generated electricity. <\/p>\n\n

\u2013 It will be interesting to see what peak outputs the system reaches in spring and summer, S\u00f6derstr\u00f6m says.<\/p>\n\n

S\u00f6derstr\u00f6m describes the cooperation as professional and based on mutual trust.<\/p>\n\n

\u201cEverything went as agreed, and the project caused no headaches. When there is trust on both sides, it is easy to work together,” S\u00f6derstr\u00f6m says. <\/p>\n","protected":false},"excerpt":{"rendered":"
