Solar systems in Bremen pay off for homes and businesses alike. There’s enough sun for profitable operation, grid electricity is expensive, and many new buildings are now even subject to a solar obligation. This guide explains what a solar system costs in Bremen, what the Bremen Solar Act requires, how grid connection with wesernetz works, and how we take your project from planning to commissioning.<\/p>\n

PVPro Solar: Your Solar System in Bremen<\/h2>\n

Planning with a Yield Forecast for Your Roof<\/h3>\n

Before we write a quote, we analyse your roof: orientation, pitch, shading and structure. From this, we create a yield forecast and size the system to your consumption, taking a battery, wallbox or heat pump into account if they’re an option for you.<\/p>\n

Brand Components from a Single Source<\/h3>\n

We install modules from AIKO, JA Solar or Longi, Fronius inverters, BYD batteries on request and the K2 Systems mounting system. These are components we know well and for which we get spare parts and support.<\/p>\n

Our Own Technicians and Registration with wesernetz<\/h3>\n

Our own certified technicians handle installation and electrical work in line with VDE and TAB rules. We take care of registration with wesernetz or wesernetz Bremerhaven and in the Market Master Data Register for you.<\/p>\n

Solar Obligation Met on Time<\/h3>\n

If you’re building new or renovating your roof, the Bremen Solar Act applies. We plan the system to meet its requirements and coordinate the schedule with your roofer or developer.<\/p>\n

Fixed Price, 30\/70 Payment and Service<\/h3>\n

You get a written fixed price and pay 30% on order and 70% after installation. We’re there for you after commissioning too, with system monitoring and service even after the statutory warranty has expired.<\/p>\n

Are Solar Systems Worth It in Bremen?<\/h2>\n

Yes. The Hanseatic city is in the north, but there’s more than enough sunlight for profitable operation. In northern Germany, we calculate about 893 kWh per kWp per year. A 10 kWp system therefore produces just under 9,000 kWh a year, considerably more than a typical household uses. Modern modules also work under cloudy skies and in the diffuse light common in the coastal climate.<\/p>\n

The return comes mainly from self-consumption. Every kilowatt-hour you use yourself saves you grid electricity, which is 37 cents at an assumed price of 37 ct\/kWh. Since 1 August 2026, new systems up to 10 kWp with partial feed-in have received only about 7.70 ct\/kWh for power fed into the grid. We show you how this works out in practice in our guide is solar worth it?<\/a><\/p>\n

How Much Does a Solar System Cost in Bremen?<\/h2>\n

As a guide, we calculate about \u20ac1,450\u20131,750 per kWp for a fully installed system without a battery:<\/p>\n\n\n\n\n\n\n\n\n
System<\/th>\nGuide price (modelled)<\/th>\n<\/tr>\n<\/thead>\n

Since 1 January 2023, the zero VAT rate has applied to the supply and installation of PV systems on or at residential buildings, so you pay 0% VAT. Commercial systems up to 30 kWp benefit too. There is currently no grant for private PV systems from either the federal government or the state of Bremen, but you can finance one with the KfW 270 loan, for example. Free, independent initial solar advice is available in Bremen from the climate protection agency energiekonsens and the Verbraucherzentrale Bremen.

Solar Obligation in Bremen: What the Bremen Solar Act Requires<\/h2>\n

The city has introduced its own solar obligation with the Bremen Solar Act (BremSolarG). According to the Senator for Environment, Climate and Science, the rules are:<\/p>\n
