Financial Analysis

Page Financial Analysis

-> To enter the parameters for cost calculation:

1. Click on Edit. The Financial Analysis Assistant will open.
   

   • Enter the required parameters on all pages.
   • Close the dialog and return to the Economic feasibility page.

2. Define the grid concept of the pv system. You can choose on of the following three grid concepts:

   • Full power supply
     In the case of full power supply, the entire electric power generated is fed to the public power grid. There is no self-consumption. The profitability of the installation depends directly on the amount of the compensation for input and/or the distribution of direct marketing.
   • Surplus input
     In the case of surplus input, the electricity generated by the photo-voltaic installation is used directly. Merely the electricity which isn't used is fed to the electrical supply grid.
     Electrical consumption and feed-in are measured by 2 separate tariff counters.
     The profitability of the PV installation results from the savings in the electrical use and the compensation for the input.
   • Net Metering
     As with the surplus input to the electrical grid, the electricity generated is used primarily for self-consumption.
     The electricity not used is fed to the electrical supply grid via a double tariff counter and calculated against the electrical consumption. In the process the tariff counter is turning backward.
     If more solar electricity is generated than consumed, the surplus can be transferred to the balance for the next period.

3. Enter the price of directly marketed current. Enter the payment you can achieve. (No legal regulation)

4. Select the Feed-in Tariffs:

   • You can add one or more input tariffs to the project via the Add button.
   • First you select the country in the Tariff selection dialog. The various compensation models are shown in the corresponding feed-in tariffs.
     You can also create your own feed-in tariffs (- see Data base menu).
   • The tariff selected is normally valid starting on the date the PV installation begins operation. You can change the validity of the feed-in tariff in the column Valid beginning.
   • Enter the price change factor for all feed-in tariffs in order to, for example, take inflation during the observation period into account.

5. Select a From Grid Tariff (-> only for Systems with surplus feed):

   • You can add one or more consumption tariffs to the project via the Add button.
   • First you select the country in the Tariff selection dialog. You can also create your own consumption tariffs here (- see Data base menu).
   • The tariff selected is normally valid starting on the date the PV installation begins operation.
   • Enter the price change factor for all consumption tariffs in order to, for example, take inflation during the observation period into account.

6. Choose a Net Metering Tariff (-> only for Systems with Net Metering):

   • You can add a Net Metering tariff to the project via the Add button.
   • First you select the country in the Tariff selection dialog. You can also create your own Net Metering tariffs here (- see Data base menu).
   • The tariff selected is normally valid starting on the date the PV installation begins operation.

7. Select an exceedance probability for the forecast yield (only for full feed-in)

   • Open the "Bankability: Exceedance probability of forecast yield" dialog by clicking on the corresponding link.
   • The variability of global irradiance and the simulation can be set in the dialog. It is then possible to select the probability that the system simulated actually provides the forecast yield.
