FAQ - The most frequently asked questions
Solar electricity
How much electricity does a 10 kWp photovoltaic system generate per day?
A photovoltaic system with an output of 10 kWp can generate around 10 kWh of energy per day in the winter months, while in the summer months it can generate up to 50 kWh per day. It is important to note that the energy yield also depends on factors such as the orientation, the angle of inclination and the exact location of the system.
How much electricity does a 10 kWp photovoltaic system generate?
A photovoltaic system with a capacity of 10 kWp is capable of generating an annual average of around 9,000 to 11,000 kWh of electricity. However, this yield varies and depends on various aspects, such as the orientation of the system, the efficiency of the solar modules and the specific solar conditions in the respective region.
Will VODASUN help me to reduce my electricity costs?
Yes! You can significantlyreduce your energy costs by investing in a photovoltaic system.
The solar power generated can be used for a variety of appliances in the home, workshop or office.
Solar system
Is a solar system worthwhile in winter?
Yes! Regardless of the time of year, the use of a solar system is undoubtedly worthwhile! Regardless of the time of year, the use of a solar system is undoubtedly worthwhile!
Hereyou find out which decisive factors are important for the optimum utilisation of a photovoltaic system during the winter period.
How does snowfall affect the performance of a solar power system?
If a thin layer of snow covers the solar system, it can still generate electricity, but not with maximum efficiency. If the snow cover is thicker, it is advisable to hire a specialist to remove it in order to prevent damage to the system.
What costs should I expect if I want to buy a PV system?
The cost of a photovoltaic system depends on your specific needs. It is helpful to know your annual electricity consumption in order to determine the necessary requirements for the system. A customised offer can be created on this basis.
The investment for a turnkey solar system without battery storage starts at around €11,000. You should calculate an entry-level price of around €15,000 for a photovoltaic system including storage. However, it should be noted that the final cost may vary depending on your individual requirements and the equipment chosen.
What does a 10 kWp solar system from VODASUN cost?
The estimated costs for a 10 kWp photovoltaic system start at around € 20,000. The final price depends on the number of modules required and your specific wishes.

What type of solar modules are installed, VODASUN?
Our commitment to sustainability is reflected in the high quality of our selected manufacturers. We work with regional German suppliers such as Trinasolar and Meyer Burger as well as with international companies such as LONGi. For further information or questions, please contact our competent team at any time.
What subsidies are available for the purchase of a private photovoltaic system?
From 1 January 2023, the funding opportunities for private solar systems have been significantly expanded.
The state now offers various forms of support:
- Exemption from VAT (19 %) on the purchase of solar systems
- Price reduction for larger solar systems up to 30 kWp for private users
- No taxes on self-consumed electricity
- Feed-in tariff for solar systems up to 10 kWp at 8.1 cents per kWh
- Various loan and subsidy programmes at federal, state and municipal level
At VODASUN, we are experts in this field and will be happy to help you find and utilise the appropriate subsidies - this way.
Why is now exactly the right time to invest in a solar system?
One or two decades ago, the feed-in tariffs for solar power were much more attractive, although photovoltaic systems were much more expensive and less efficient at the time.
Today, these systems have become much cheaper and more efficient. In addition, the current high electricity prices are motivating many people to become less dependent on electricity suppliers by installing their own photovoltaic system. Despite falling feed-in tariffs for solar power, it can be particularly advantageous to start using solar energy today.
With a guaranteed feed-in tariff for 20 years and our comprehensive carefree package, you are not taking any risks. You are protected from unpleasant surprises and can calculate your financial savings precisely.
How does the recycling of a solar system work?
The solar industry is actively working on optimising recycling processes and minimising the environmental impact of solar systems. Manufacturers are legally obliged to recycle both solar modules and battery storage systems. The manufacturers take solar modules free of charge and ensure that they are reintegrated into the raw material cycle.
Electricity feed-in
Can I also feed the unused electricity into the grid?
The so-called surplus feed-in of unused electricity is generally possible. With the help of a power of attorney, which can be submitted via our solar configurator, we will enquire about this option for you with your local grid operator.
With the help of a power of attorney, which can be submitted via our solar configurator, we will enquire about this option for you with your local grid operator.
From whom, when and how do I receive the feed-in tariff?
The provisions for the feed-in tariff are determined by your local grid operator.
For further information, please contact your regional network operator directly.
He can give you more precise information about whether the payments are made monthly or annually.
How does the feed-in tariff work?
As soon as your photovoltaic system is commissioned, a bidirectional meter is usually installed. This meter measures the electricity fed into the grid, which is then billed by the grid operator.
What happens to the feed-in tariff if the registration process with the grid operator takes longer?
The feed-in tariff generally starts from the time the photovoltaic system is commissioned and not from the time of registration with your grid operator. So you don't have to worry about missing out on rewards, even if the registration process takes a little longer.
Installation & Registration
What requirements should my roof and building electrics fulfil for a solar power system?
Both the building and the roof truss must be stable and in good condition to bear the additional load of the solar system. If your roof is in need of renovation, you will receive a free roof renovation from VODASUN® if you have a roof area of at least 1000 m².
In principle, a three-phase electrical system is required for the installation of a photovoltaic system. This is already installed in most houses and the installation can be carried out without major difficulties. If this is not the case, we will be happy to commission a specialist partner.
Why should I have my solar system built by VODASUN?
During the 13-year history of VODASUN, we have built up an impressive series of successfully realised photovoltaic projects. Our dedication to sustainable solutions and renewable energy has earned us a reputation as a reliable and reputable company in the industry. Well-known customers such as NürnbergMesse, Messe Berlin and Meissen-Porzellan already rely on our expertise.
Can I contact VODASUN for maintenance even after the solar system has been installed?
Of course! Even after the installation of your solar system, we at VODASUN are available for maintenance and service enquiries. If it is necessary to replace components, we will check for you whether any warranty claims still exist with the manufacturer and inform you of the next necessary steps.
The photovoltaic system is on the roof, when will it be put into operation?
Once the installation work on the roof has been completed and the photovoltaic system has been fully installed, it normally only takes a few days to a few weeks before the system is ready for operation. We will keep you informed about the exact date of commissioning.
Do I have to register the solar power system with the grid operator and in the market master data register?
Don't worry, to make the bureaucratic hurdles easier for you, we offer you the option of granting us a power of attorney. With this authorisation, we take over the entire process of registering your solar installation with the grid operator and in the market master data register for you.
How long does it take for the solar system to be registered with the grid operator?
We will immediately register your photovoltaic system with the responsible grid operator. The processing time may vary and depends on the respective network operator.
