Gladly, we would like to make a direct contact to a specialist planner in your region. The more information you enter in advance, the faster you get a realistic offer.
Price of the solar electric system
Please consider: The calculation of the system price is based on average assumptions and is therefore non-binding.
For an accurate calculation, a local appointment as well as a system calculation and dimensioning by a specialist is necessary.
With appropriate consideration, the value-added tax could be refunded by the finance office. For this, please consult a tax expert.
Adjustment of the feed-in remuneration according to the EEG
There is no feed-in remuneration for your chosen period of commissioning. The calculation
of your return on investment is therefore based on a non-binding forecast, based on the current market situation.
Forecast based on the current market situation.
A degression value is already known for this month.
Einspeisetarife
The Renewable-Energy-Act (EEG) provides a gradual reduction of the feed-in remuneration.
Thus, the time of commissioning determines -
apart from the system type, the system size and the share of self-consumption - The amount of remuneration for
electricity fed into the grid.
Specific system yield:
As a general rule, the annual average yield of a solar electric system in Northern Germany is about 880 kWh/kWp.
Please use our yield forecast if you are interested in a detailed calculation.
Costs of the PV system
The indicated costs are an average value, which can be higher or lower depending on local conditions and the pv-system size.
By sending your project, this value will be determined by the specialist company.
Costs of the PV system
The stated costs are estimated costs which are calculated by the installer.
Additional one-off costs
For example, for capitalized lease, emergency expenses or remote monitoring.
Additional costs for technical implementation in the case of self-consumption or load management will be considered separately!
Equity
Depending on the investment strategy and the tax situation, a higher or lower equity ratio is recommended.
Please contact your tax consultant to determine the optimal equity ratio for you.
Total system size:
As a general rule, a maximum power output of 1 kWp requires ca. 7 - 8 square meters of installed crystalline modules.
Please note:
In the case of flat-roof or open area systems, only about one third of the available area can be counted as a pv-area. To avoid mutual shading, a certain distance between the rows of modules is necessary.
Interim financing
Interim financing is always an adequate option when a short-term
loan is needed until the loan can be repaid either through a long-term loan or by equity.
The default values given here currently are standard values.
Period under consideration (profitability)
Please specify the duration of the investment (in years) in order to determine the profitability of the solar electric system.
One-time subsidies
Please enter here whether the costs of the planned photovoltaic system can be reduced by a one-time grant e.g. which are provided by regional or national promotional programs.
The system costs will be reduced by this amount in the profitability calculation.
Profitability forecast of your solar electric installation
A forecast is only as accurate as the underlying data:
The more accurate your information, the more reliable the result will be.
Please fill in at least the fields that are highlighted in yellow.
In combination with the project data which are preset to average values, these are required to determine
the yield and the profitability of the solar electric system. Additional data enhances the accuracy of the calculations.
In order to get a realistic estimate before the buying decision, all assumptions should be examined and adjusted if necessary.
You can do this on your own by clicking on the start-button in the top line of the tool and then verifying the data of your project one after the other.
Information on your object data, e. g. the area available for the project, affects the system size and cost estimate – these two parameters form the basis of the following calculations.
