BlueSol generates a detailed table of all parameters of economic
evaluation, detailed per year for the assessment period of the system:
-
Year: Year of PV system life
-
Energy 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
-
Energy taken from the grid
[kWh]: Energy consumed by the user and coming from the grid
-
Total revenue [currency]: [Revenu
of feed-in tariff] + Revenue
from energy sale or Revenue from net metering
-
Revenue of feed-in tariff on energy produced
[currency]: Energy produced * Feed-in
tariff for the produced energy
-
Revenue of feed-in tariff on energy
fed into grid [currency]: Energy fed into grid * Feed-in
tariff for energy fed to the grid
-
Revenue of feed-in tariff on energy self-consumed
[currency]: Energy self-consumed * Feed-in
tariff for self-consumed energy
-
Revenue from energy sale
[currency]: Energy fed into grid * sale price
-
Revenue from net metering [currency]:
Valorization of energy escanged into the grid
-
Energy purchase tariff
[currency/ kWh]: Energy purchase tariff (see Average
cost of electricity withdrawn in Energy
consumption section) revalued annually by the Energy
price inflation
-
Saving on energy bill
[currency]: Savings due to non-purchase of energy. Calculated as Self-consumption
* Energy purchase tariff
-
Maintenance costs
[currency]: Cost of maintenance periodic and extraordinary
-
Financing [currency]: 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 [currency]:
Principal portion of the installment loan
-
Loan interest amount
[currency]: Interest portion of the installment loan
-
Gross profit [currency]: Total
revenue + Saving
on energy bill - Maintenance
costs - Depreciation
- Loan
interest amount
-
Total tax [currency]: Taxable
income * Tax rate
for income (see Taxes)
-
Taxable income [currency]:
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 not handle tax credits, so if Taxable
income is negative then Total
tax will be forced to zero.
-
Income subject to tax
[currency]: Part of the Total revenue
subject to tax
-
Depreciation [currency]:
Depreciation of the system, calculated for each year as the Realization
cost * System depreciation
* Annual Depreciation (see Taxes)
-
Net profit [currency]: Gross
profit - Total
tax
-
Cash flow [currency]: Net
profit + Depreciation
- Loan
capital amount
-
Cumulative cash flow [currency]: 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)
[currency]: By calculating the NPV is established the convenience
expected of investment, by discounting the future cash flows in order
to detect the present value of the investment.
