The Pomeranian Voivodeship is one of the fastest-growing photovoltaic markets in Poland - and, at the same time, a region with several specific conditions that you won't find in guidebooks written \u201efor Krakow\u201d. Wind from the sea, variable cloudiness, salty air in the coastal zone and the highest electricity prices in the country - all of these affect how a PV installation should be designed in Gdansk, Gdynia, Sopot and the surrounding area.<\/span><\/i><\/p>\n

Sunshine in Pomerania - less than in the south, but still profitable<\/h2>\n

The first thing any honest photovoltaic dealer in the region will tell you: there is less sun here than in the Lesser Poland or Podkarpacie regions. Data IMGW<\/a> for the multiannual period 1991-2020 confirm that the Pomeranian Voivodeship records 1 400-1 550 hours of sunshine per year, while the south of Poland achieves 1 600-1 750 hours. This is a difference of approximately 10-15%.<\/p>\n

But what evens out the bill? Electricity prices in the Tri-city are among the highest in Poland - approx. 1,15-1,30<\/strong> PLN\/kWh<\/strong> on the G11 tariff. The more expensive the energy from the grid, the more each kilowatt hour from your own panels is worth. As a result, the payback time for photovoltaics in Gdansk is comparable to the centre of Poland, despite less sunshine.<\/p>\n

An important nuance:<\/h4>\n

In summer, the difference in sunshine between Pomerania and the south almost disappears - from May to August the monthly number of hours of sunshine is similar throughout Poland (approx. 180-220 h)<\/strong>. A key difference emerges in winter: December-February in Pomerania yields a mere 20-40 h<\/strong>\/month, vs. 50-80 h<\/strong> in the south. This is why energy storage is a particularly valuable addition to the plant here.<\/p>\n<\/div>\n<\/div>\n

Marine climate and PV installation - what does it change technically?<\/h2>\n

A photovoltaic installation in Gdansk Jelitkowo or Sopot stands in completely different conditions than the same installation 200 km inland. The maritime climate brings with it several specific challenges:<\/p>\n

1. air salinity and salt spray<\/h3>\n

In the area a few kilometres from the Baltic coast, the air contains microscopic salt particles, which settle on the panels and can accelerate the corrosion of construction elements. It is worth paying attention to the quality of the materials used as early as the offer selection stage.<\/p>\n
