Net worth calculator: Determine the value of your PV system in 4 steps

Do you know what your PV installation is worth? With the net worth calculator for running solar systems, you can quickly and cost-effectively determine the sales value of your installation. In just four steps, you can calculate the fair value of your PV system at a time you define.

 

1. The net worth calculator

Using various parameters, the net worth calculator determines a possible sales value of your photovoltaic system at an individual time defined by you. At www.milkthesun.com/en/pv-system/services/rate/net-worth-calculator you will find our free sales calculator, you can get further information about the calculation of PV systems and take the first step towards your calculation. To do so, you will define the size, the network and the specific yield of your photovoltaic system with the slider. Click on “Calculate” to enter the specific plant data.

 

2. Registration

After clicking the “Calculate” button, you will be prompted to log in. If you do not already have an account, you can register now for free. In the following, you will be redirected to the detail query of the computer and your entered data will be accepted. If you are already registered, you will be redirected directly to the query of the specific plant data (see point 3). Registration at Milk the Sun is fast and free.

3. Enter the specific plant data

By entering various plant data, the net worth calculator can precisely calculate the fair value of your PV system. The following is an explanation of the data you need.

Milk the Sun Calculator

Length of the compensation through the Renewable Energy Sources Act (Germany):
This point indicates the duration of the remuneration rates by the Renewable Energy Sources Act. The applicable remuneration rate for the year of commissioning is regulated in this act. The system operator is paid for this from the month of commissioning onwards. The remuneration rate is then also valid for the following 20 years. For English PV systems please use the duration of the feed-in tariffs (FIT), for Italian the Conto-Energia etc.

Grid access:
This term refers to the point in time when the PV system was connected to the power supply.

Specific yield:
A watt hour (Wh) indicates how much energy can be absorbed or discharged in one hour by a machine with one wattage of power. The rated output of a photovoltaic plant is measured in kilowatt-peak (kWp).

Installed power:
Enter the installed rated output in kilowatt peak (kWp) in this input field.

Cost of new plant:
This point describes the net amount for which the plant was originally built.

Amount of feed-in tariff: This point describes the amount of feed-in tariffs according to the Renewable Energy Sources Act. If you are not based in Germany, different systems may apply. For Great Britain, for example, the feed-in tariff is regulated by FIT rates, in Italy it is defined by Conto-Energia. The amount of the feed-in tariff can be found on the invoices of your network operator. In case of installations which are still to be built, you can get the tariffs for example at the Federal Network Agency (Germany) or from your network operator.

Self-consumption:
The self-consumption describes the percentage to which you consume or market the electricity you produce.

Reimbursement of personal consumption:
This point indicates the yielded amount (in euros) per kilowatt hour that is a result of self-consumption or the self-marketing of your electricity.

Remuneration after expiry of the Renewable Energy Sources Act:
In this field, a possible agreed remuneration can be taken into account after expiry of the Renewable Energy Sources Act (or your country’s equivalent) remuneration. It is mainly relevant for further calculations.

Power loss per year:
The loss of power per year describes the decrease in the performance of your PV modules per year. It is expressed as a percentage.

Operating costs p.a.:
The operating costs are the sum that incurres each year for the operation of your PV system. This includes the costs of insurance, maintenance and care, monitoring and the like.

Lease p.a.:
Lease refers to a contractually regulated lease of the use of the photovoltaic plant (or of the PV project rights) and the profits generated by it. The transfer is made for a fee. If you have made a pre-payment at the beginning, please enter 0 € and add the one-time payment to the new costs. If the lease consists of an average value of the feed-in tariff, please calculate an average and enter it into this field.

Period of amortization:
The depreciation is calculated over the life of the solar system and refers to, from the company’s accounting, a planned or unplanned reduction of the value of the plant.

Expected inflation p.a.:
This point describes the average percentage of inflation that can be expected each year. As a term coming from economics, inflation indicates an annual increase in purchase prices and, in this context, a drop in the purchasing power of money. The annual inflation rate can be found on global-rates.com. Normally, an inflation rate of around two percent is to be expected.

Tax:
In the Tax entry field, enter the percentage of company tax that you pay for your PV system or your special purpose entity.

Proportion of borrowed capital:
In this field please enter the percentage of the purchase price of the PV system financed by borrowed capital.

Interest rate:
For this, please enter the interest rate that has been set for the borrowed capital available to you.

Runtime:
As runtime, kindly enter the number of years for which the credit for the external financing of your PV system has been created.

Repayment-free period:
The term repayment-free period means a period preceding the repayment term which indicates an initial redemption delay. If such a period has been agreed on, please indicate at this point how many months this is.

Planned sales date:
Enter the planned date of sale of the PV system.

Please do not insert thousands separators, and the decimal places are separated by dots rather than commas. The fields marked with a blue asterisk are mandatory input fields, which are necessary in each case to calculate the sales value of the photovoltaic plant. The more detailed the information, the more precise the results.

After completing the form, please click on “Calculate”.

 

4. Result

And that was it. The result of your calculation is now displayed in two tables. The upper one represents a sales value taking into account the previously realized purchase price and the expected sales and costs of the PV system (net present value method) at the sales date you entered. The table below shows possible returns based on the information provided by you.

The bottom table shows in the left column the potential equity return of the potential investor, should he be able to take over the financing and provided that all the parameters applied remain unchanged. The right column shows the selling price for the corresponding investor yield.

Afterwards you have the possibility to sell the project on the Milk the Sun market place by clicking on the button “sell project“.
