PV*SOL Expert 6.0 - Manual - Valentin Software

11.3.1.1 Technical Input
(grid-connected system) Calculation > Economic Efficiency Calculation > Technical Input
This dialog shows the basic parameters in PV*SOL which are relevant for the Economic
Efficiency Calculation.
-> How to proceed in Germany:
1. Economic Efficiency Variant: Name your system.
2. Start Date: Enter the system operation start date, it is required for the proportionate
allowance for lodgements and disbursements made in the first year.
3. If you let the option British / Italian Feed-in Tariff, empty, then the German EEG is used
for calculations.
The following technical data are displayed:
• Peak PV power,
• PV electricity generated in first year,
• conserved electricity (in first year)
• Electricity to grid (in first year)
4. Enter the percentage of the PV electricity legally compensated. (EEG 2012: in Germany:
80%; other countries (until further notice): 100%)
The corresponding data are calculated and displayed:
• Maximum compensated electricity fed into the grid
• unpaid electricity fed into the grid
5. Calculate savings: Choose either:
Calculate Savings from Reference Tariff, then you can load a Household Tariff. The
corresponding saving is displayed in €/kWh, or
Set Predetermined Savings, then you enter a value in €/kWh.
6. Calculate payment: Choose either:
Calculate Payment from Feed-in Tariff, then you can load a Feed-in Tariff. The
corresponding payment is displayed in €/kWh, or
Set Feed-in Payment, then you enter a value in €/kWh.
7. Market value of unpaid electricity fed into the grid: Enter the payment you can achieve.
(No legal regulation)
8. Continue to the next page to set the General Parameters or Close the economic efficiency
calculation.
-> How to proceed in Great Britain or Italy:
1. Economic Efficiency Variant: Name your system.
2. Start Date: Enter the system operation start date, it is required for the proportionate
allowance for lodgements and disbursements made in the first year.
