2.2.1 - DEFINITIONS OF ECONOMIC ANALYSIS TABLE
Production [kWh]: Energy production estimated by the program. Also
matches the Energy fed to grid + Self-consumption.
Energy fed to grid [kWh]: Energy produced by the system and fed into
the grid because not consumed by users of the PV system.
Energy consumption [kWh]: Annual energy consumption, including any
increases in consumption. Also matches Self-consumption + Energy
taken from the grid.
Self-consumption [kWh]: The amount of energy produced by the
system and at the same time consumed by the users of system.
Economic analysis - JAROSЈAW LEWANDOWSKI
9
Energy taken from grid [kWh]: Energy consumed by the user and
coming from the grid.
Revenue of feed-in tariff on energy produced [zі]: Energy produced *
Feed-in tariff for the produced energy.
Revenue of feed-in tariff on energy fed into grid [zі]: Energy fed into
grid * Feed-in tariff for energy fed to the grid.
Revenue of feed-in tariff on energy self-consumed [zі]: Energy selfconsumed * Feed-in tariff for self-consumed energy.
Revenue from net metering [zі]: Valorization of energy escanged into
the grid.
Total revenue [zі]: Revenu of feed-in tariff + Revenue from net
metering.
Energy purchase tariff [zі/kWh]: Energy purchase tariff revalued
annually by the Energy price inflation.
Saving on energy bill [zі]: Savings due to non-purchase of energy.
Calculated as Self-consumption * Energy purchase tariff.
Maintenance costs [zі]: Cost of maintenance periodic and
extraordinary.
Depreciation [zі]: Depreciation of the system, calculated for each year
as the Realization cost * System depreciation * Annual Depreciation.
Financing [zі]: Amount of annual installment with financing. The
amount is calculated by the program based on the capital to be
financed. Also, matches Loan capital amount + Loan interest amount.
Loan capital amount [zі]: Principal portion of the installment loan.
Loan interest amount [zі]: Interest portion of the installment loan.
Gross profit [zі]: Total revenue + Saving on energy bill + Tax
detraction - Maintenance costs - Depreciation - Loan interest amount.
Total tax [zі]: Taxable income * Tax rate for income.
Income subject to tax [zі]: Part of the Total revenue subject to tax.
Taxable income [zі]: Refers to the basis upon which an income tax
system imposes the taxes, calculated for each year as Income subject
to tax - Maintenance costs - Depreciation. Note that the program does
Economic analysis - JAROSЈAW LEWANDOWSKI
10
not handle tax credits, so if Taxable income is negative then Total tax
will be forced to zero.
Tax detraction [zі]: Amount to detract by annual amount of tax, it is a
percentage of the cost of the system divided into a period of years.
Net profit [zі]: Gross profit - Total tax.
Cash flow [zі]: Net profit + Depreciation - Loan capital amount.
Cumulative cash flow [zі]: cash flow of year + cash flow of previous
year. The first year is calculated as: cash flow of year - system cost +
amount to be financed.
Net present value (NPV) [zі]: By calculating the NPV is established the
convenience expected of investment, by discounting the future cash
flows to detect the present value of the investment.
