- In Göttingen and Southern Lower Saxony, each kWp of solar capacity produces around 950 to 1,050 kWh of electricity a year – enough for a system to pay off well.
- With us, a 10 kWp system costs about €10,000 to €13,000, with a 10 kWh battery about €13,000 to €17,500 – fully installed.
- East-west roofs, flat roofs and many houses in village and town centres are also suitable. Listed buildings need a permit.
- We take care of registration with the grid operator and in the Marktstammdatenregister (the federal register of energy installations) for you.
Whether in Göttingen’s Weststadt, in Rosdorf, Bovenden, Northeim or Hann. Münden: more and more roofs in Southern Lower Saxony have solar modules on them. Even so, many homeowners ask us whether there is “enough sun” here and what a system costs. In this guide we answer the questions that matter particularly in our region.
Is there enough sun in Göttingen?
Yes. What matters is not the heat but the light – and there is plenty of that in Southern Lower Saxony. A well-aligned system here produces around 950 to 1,050 kWh of electricity a year per installed kilowatt peak (kWp). That is only slightly less than in southern Germany.
| System size | Electricity yield per year (Southern Lower Saxony) | Suitable for |
|---|---|---|
| 6 kWp | approx. 5,700–6,300 kWh | 1–2 people |
| 10 kWp | approx. 9,500–10,500 kWh | 3–4 people |
| 14 kWp | approx. 13,300–14,700 kWh | Family with e-car or heat pump |
A south-facing roof delivers the most. An east-west roof produces about 10 to 15 % less, but spreads the power better over the day – in the morning and evening, when many families are at home. Flat roofs on garages, extensions and halls can also be put to good use.
What does a solar system cost in Göttingen?
Our guide prices for a fully installed system, including scaffolding, installation, electrical work and registration:
| System | Without battery | With battery (~10 kWh) |
|---|---|---|
| 6 kWp | 6.500–8.000 € | 10.000–12.500 € |
| 10 kWp | 10.000–13.000 € | 13.000–17.500 € |
| 14 kWp | 14.000–18.000 € | 17.500–22.500 € |
For private systems up to 30 kWp you pay 0 % VAT. We give you the exact price as a fixed price after the free site visit. You can find more about costs and a detailed example calculation in our article What does a solar system cost in 2026?
The roof check shows you the size, price and savings for your house in 2 minutes.
Grid operators and registration in the region
Every solar system must be registered with the responsible grid operator and entered in the Federal Network Agency's market master data register. Which grid operator is responsible depends on the location – in southern Lower Saxony, depending on the municipality, this is for example EAM (in Göttingen and parts of the Northeim district), Stadtwerke Bovenden or Stadtwerke Northeim. You don't have to find this out: we clarify it during planning and handle the registration for you.
In many houses the meter cabinet also has to be checked. Older cabinets sometimes no longer meet today’s requirements. We spot this during the site visit and tell you the costs in advance.
Old town and listed buildings
In Göttingen city centre, in Hann. Münden and in many historic village and town centres, houses are listed or part of a protected group of buildings. A solar system is not automatically prohibited there.
- Lower Saxony has changed its heritage protection law: renewable energy now carries much more weight when the interests are weighed up.
- You still need a permit from the local heritage protection authority before installation begins.
- Discreet solutions often help, for example all-black modules or a system on the side of the house that cannot be seen from the street.
How your project works with us
- Free consultation: by phone, via WhatsApp or in person at your home.
- Site visit and fixed-price quote: we look at your roof and meter cabinet and work out honestly what is worthwhile for you.
- Registration: we register the system with the grid operator.
- Installation: we install the system, usually in one to two days.
- Commissioning: we put the system into operation and show you the app.
You can find the process in full detail, with a checklist, in our article How a solar installation works.
Why a specialist from the region?
We are based in Hardegsen, in the heart of the district of Northeim. That has real advantages for you: short distances for the site visit, one permanent contact person and someone who can be with you quickly after installation, too, if you have a question.
Conclusion
Göttingen and Southern Lower Saxony are a good location for solar PV. With the right modules, the right size and – depending on your consumption – a battery, a system here reliably pays for itself. We are happy to tell you free of charge what is possible for your house.
Frequently asked questions
How much electricity does a 10 kWp system produce in Göttingen?
Around 9,500 to 10,500 kWh a year, depending on the direction and pitch of the roof. That is more than a family of four uses in the household.
Is solar PV worth it on an east-west roof too?
Yes. An east-west roof produces about 10 to 15 % less than a south-facing roof, but spreads the power better over the day. This often lets you use more of it yourself.
Can I install a solar system in Göttingen’s old town?
Often yes, but for listed buildings only with a permit from the local heritage protection authority. We will tell you during the consultation what is needed.
