Your roof can do more than just look good
We were one of the first to combine the topics of roofing and solar.
Our vision at the time "from protective roof to utility roof" was unique in the trade sector. With the constantly changing requirements in solar technology, we have also continued to develop.
In the meantime, with the expertise of the entire Hanebutt Group behind us, a successful and reliable team of specialists and installers has emerged. The Hanebutt Solar GmbH.
From consulting and planning to technically skilled implementation, Hanebutt Solar offers the entire range of services from a wide variety of modules, storage systems,
heating with fuel rods, heat pumps and wallboxes to make the sun's energy usable for you.

What is photovoltaics?
Photovoltaics describes the production of useful energy, generated by light energy, i.e. simply the conversion of sunlight into electrical energy using so-called solar cells. What can be found on rooftops in almost every housing estate these days is still familiar to most people from pocket calculators. Back then, however, it simply switched off as soon as the small solar collector was closed, but now we don't just stand at home in the dark when the sun isn't shining and isn't providing any visible energy.
Solar power systems, also known as photovoltaic or PV systems, convert solar energy into electricity.
Advantages of solar energy at a glance
1. electricity is produced even in cloudy weather
2. few special site requirements or extra space
3. can be easily adapted to structural conditions using individual elements
4. various utilisation options through electricity and/or heat generation
5. large own use through sale, own consumption and additional subsidy programmes
6. discreet installation and silent operation
Why is photovoltaics so popular?
Energy with photovoltaics even without direct sunlight
Summer, sun, sunshine. When we think of solar utilisation, our first thought is to generate electricity or heat when the weather is not good. Solar utilisation goes way back to the 1950s and since then has produced a great deal of innovation and developed itself further so that energy can be generated even when the sun is not shining.
Flexibility of solar technology
The flexibility of solar technology means that there are fewer siting requirements for energy generation than with most sustainable methods, such as biogas plants and wind turbines.
Customisation of solar technology
As solar technology is modular, the many individual elements can be customised to suit individual needs, circumstances and structural conditions.
Versatility of solar technology
Until a few years ago, solar cells were only seen on the roofs of a few houses, but today they seem to be everywhere. Even on facades. However, they are not only installed on the roofs of houses, but also on the ends of façades, including charging stations for electric cars. This wide range of services is Hanebutt's speciality and is rarely found on such a scale.
Financial benefits of PV systems
Although the feed-in tariffs may have fallen, self-supply of electricity, as well as the mixture of self-consumption and feed-in, is still worthwhile.
Depending on the initial situation, more than half of the hot water costs can be covered by hot water solar thermal energy.
Subsidy programmes for photovoltaics
In order to counteract global warming, sustainable electricity generation is of course also relevant.
Longevity of PV systems
Even after 30 years, high-quality solar systems can still reliably generate electricity.
Discreet and unobtrusive installation of photovoltaic systems
Anyone who is bothered by external inconsistencies can rest assured, as solar technology can be integrated inconspicuously into the architectural environment to create a harmonious overall picture. Solar technology also works without generating operating noise.
Solar energy - good for the climate and your wallet
Solar energy may have been very expensive in the past, but today it is actually the cheapest method of generating electricity when installed correctly. Basically, it can be said that there is almost nothing to be said against generating solar energy, as it not only saves costs but also protects the climate at the same time. And what could be better than earning money in a morally correct way?
Solar energy generation is therefore a sustainable solution for consumers and the environment and promotes sustainable mobility and creates innovation.
A go for solar energy generation and now?
Photovoltaic systems can be installed almost anywhere. Be it on residential buildings, public facilities or commercial and industrial properties. Once the decision to install photovoltaic systems has been made, the foundation stone has already been laid, but the work is still in its infancy. Once the fundamental decision in favour of photovoltaics has been made, it is also necessary to carefully consider how it is to be used and how a sensible and desired installation can be made possible. A decision must also be made on the utilisation of solar power and solar thermal energy. While solar power is used purely to generate electricity, solar thermal energy focuses on heating domestic hot water or supporting the heating system.
It must also be borne in mind that sometimes modifications have to be made in order to lay solar pipes between the collectors and the storage tank. Furthermore, when installing collectors on the roof, a suitable roof surface is required, as shadows from trees or neighbouring buildings can significantly reduce the solar yield.
Integrated PV systems from Hanebutt
If you are interested in a façade installation of PV systems, Hanebutt is one of the few providers who also carry out this work. Not only façades, but also PV systems integrated into buildings in general are carried out professionally and effectively by Hanebutt. This means that a PV system can also be integrated in place of roof tiles during an energy-efficient building renovation. In this way, you can turn your protective roof into a usable roof.
Integration of wallboxes
PV systems offer a wide range of possible applications. Nowadays, we no longer just use electricity to light up our homes, but for everything we do. Today, electricity is real money, information, communication and power. Without electricity, we have no technical devices and are therefore completely lost, because who can still climb a mountain on a bike without a drive or read a book in paper form? Yuk!
Electricity is our everyday life and if you want to take it that far: our life. So of course it makes sense to think about how to get electricity in the future, cheaply and sensibly.
If you haven't necessarily done your weekly shopping by bike, but have been at the front of the queue, waved goodbye to the gear lever and switched to an electric car, you may have heard of a wallbox.
Wallboxes are boxes that can be installed at your home or in garages to provide a private charging station for your electric car. Not only is this much more convenient than driving to public petrol stations or having to wait ages for the car to charge via the normal socket, it also makes refuelling much cheaper.
Using various online functions, apps or smart homes, you can even determine exactly when enough electricity is being produced by the PV system, so that you can refuel for free without having to draw additional electricity from the public grid and when it might not make so much sense.
Of course, the same also applies to all other applications such as dishwashers or washing machines, showers or heating. Some configurations can even send notifications or make it possible to switch on and off while on the move in order to make the best possible use of a PV system.
Not only is the control system much more intuitive, a wallbox also makes sense, as self-consumption of self-generated electricity is ultimately more financially viable than feeding into the public grid.
Photovoltaics or solar thermal energy?
As soon as you find out about energy supply, you can't avoid these two terms. But what exactly do they mean and how do they differ?
A photovoltaic system produces electricity. This electricity, which is generated by photovoltaic modules and sunlight shining on them, can then either be consumed in the household or fed into the public electricity grid and sold. As it is now also possible to feed electricity into the grid, relatively little energy is lost at peak times (i.e. in sunny weather).
However, the situation is different with solar thermal systems. Particularly in summer, the surplus solar energy that is not used directly can be lost or only stored by the system itself, but not sold into the general electricity grid. However, these private storage systems are usually not large enough and therefore not all of the energy generated can ultimately be utilised.
However, the decision does not have to be made between the two, but can also be utilised simultaneously or via hybrid models if there is sufficient budget and space.
Advantages of PV systems
However, PV systems are completely sufficient to supply the entire building with electricity and heat. This is because heating can also be powered by electricity and hot water can be generated by heating elements or heat pumps. As electricity is the future and can also be influenced more easily and is currently much easier to store, PV systems are much more future-orientated.
General advantages of PV systems
- Power generation and supply of household appliances
- Charging stations for electric cars through wallboxes
- Heating and hot water through heat pumps and heating rods
- No water on the roof as with solar thermal systems
- Visually invisible or more aesthetic than solar thermal systems
- Can be stored
- Feed into the general power grid
- Monitoring of power consumption and power generation
- Smart home integration
Solar thermal energy | Photovoltaics | |
Type of energy generated | Heat | Electricity and heat produced by electricity |
Technology | Solar collectors | Photovoltaic modules |
Area of application | ❌Electricity ✔️Heizung ✔️Warmwasser Charging station for ❌electric car | ✔️Strom ✔️Heizung (e.g. with heat pumps) ✔️Warmwasser ✔️Ladestation for electric car |
Feed into the public grid | no | Yes |
It is also very likely that heating systems will be replaced by infrared heating in the future, meaning that solar thermal systems will have little or no reason to exist.
Maintenance of PV systems
Maintenance is right and important!
To ensure that you can always get the best out of your PV systems, that damage is repaired before it leads to failures and that your system can be fully utilised, it is essential to have the system checked and cleaned regularly.
Hanebutt offers maintenance contracts for this purpose, where you as the customer decide for yourself at what intervals we should check your system. You may want to close the issue for yourself after installation, but regular checks and the rectification of even the smallest defects can protect you from large sums of money later on.
During a maintenance appointment, we will check your storage tank, the modules and the entire system itself. We also offer service and repair for systems not installed by us.
Your advantage with Hanebutt
Hanebutt not only offers a comprehensive service package for all photovoltaic installations on your building, we also have a number of specialist partners with whom we work. For example, we are the only specialist partner in Hanover of SMA, the leading inverter manufacturer. Our specialist partner in the module sector is also the renowned manufacturer Meyer Burger. This enables us to guarantee professional systems, excellent quality and co-operation with first-class PV system manufacturers.
FAQ
Photovoltaics produces electricity, solar thermal energy produces heat. Photovoltaics and solar thermal energy are technical processes for generating energy (solar energy) from the light or radiation of the sun. In principle, solar energy can be understood as both heat and electricity.
We would be happy to advise you on this. At Hanebutt, we are experts in the field and can advise you on making the right decision for your individual needs.
Typically, a photovoltaic system costs
Photovoltaic system | 3-4 kWp | 6-7 kWp | 9 kWp | 12 kWp |
Size in m² | 21 | 29,4 | 44,1 | 58,8 |
Acquisition costs per m² in € | 512 | 410 | 338 | 307 |
Cost per kWp in € | 2.500 | 2.000 | 1.650 | 1.500 |
PV system costs in € | 10.750 | 12.040 | 14.900 | 18.060 |
Cost of electricity storage in € | 6.200 | 6.300 | 8.250 | 10.150 |
In principle, small systems are more expensive than large systems, which is why it makes sense to look at the difference in detail and also take a forward-looking approach, but here too Hanebutt will be happy to advise you on what ultimately makes the most sense for your individual situation.
For a precise and individualised cost calculation, simply make an appointment with us and together we will work out the costs for your PV system.
With a storage system of 5-7kW, costs of €6,000-€8,000 can be expected. For a larger storage system of around 10kWp, the costs are more likely to be between €18,000 and €26,000. The complete system including a 10kWp storage system is then around €41,5,000 - €55,000 and €8,000 to €10,000 for a smaller storage system, depending on the circumstances.
For an exact and individual cost calculation, simply make an appointment with us and together we will work out the costs for your PV storage system.
Solar power from a photovoltaic system is cheaper than electricity from the grid. This means that a PV system is worthwhile in any case. With PV systems, you benefit fundamentally from more control and awareness when consuming electricity, cheaper electricity, selling electricity to the public grid, a clear conscience when consuming electricity, independence and much more.
Storage systems for photovoltaic systems can certainly be retrofitted, but not every PV storage system is suitable for this.
With full roof occupancy, the subsidy amounts to approx. €150 per kWh up to a maximum of €1,500. With additional battery storage, the subsidy is also €150 per kWh of usable storage capacity.
Money plays a major role, especially when it comes to upgrading issues around the house, we are often faced with huge sums of money. When it comes to subsidies for photovoltaics, you are in good hands with Hanebutt. We are familiar with all the options for subsidy programmes and will be happy to advise you on your personal system and savings opportunities.
Installing a wallbox at home or in the garage to charge your car is definitely worthwhile! Not only is charging your car much faster than using a normal socket, wallboxes also save a huge amount of money compared to public electric charging stations. In addition, self-consumption of electricity from PV systems is much more financially worthwhile than selling it when feeding it into the grid.
If you integrate your wallbox into a smart home or have an app for it on your mobile phone, you can even find out exactly at what times of day there is so much energy currently being produced that you can plug in and charge your car completely free of charge.
Hanebutt will be happy to dismantle and dispose of your solar thermal system. If required, we can then install a PV system with heating rods and sector coupling or heat pumps.
Please do not hesitate to contact us. We will provide you with comprehensive advice at any time.
