PVsyst 7 - Economic Evaluation 002 - Global overview - YouTube

The first step of the economic evaluation consists in defining investment costs and charges

Prices may be defined either globally,

or by watt-peak

or by square meter

You can choose any currency for the economic evaluation

In this example we will choose global definitions

First define the initial investment costs of your system

Investment consists of component costs,

other costs such as studies, insurance, bank charges,

and taxes

You can also reorder, update and delete existing costs,

or create your own costs according to your system and needs

By clicking here, you can restore the default PVsyst cost list

You can also manage cost list templates that can be reused in several projects

Let's set all the investment costs

Quantities for components are retrieved from the system definitions, you cannot modify them

You can modify component's price in database by clicking on this button

Let's set all other investment costs

The total cost of the installation is calculated, with the depreciable part. See the PVsyst help for a detailed explanation of depreciable assets

Then define the yearly operating costs, such as maintenance, salaries and taxes.

As for installation costs, you can customize the operating cost list . You can reorder items, update them and delete or add new items.

Now let us fill the annual operating costs

Now let us define the financial parameters of the project

This window contains all financial parameters of your project, such as inflation

taxes

depreciation and distribution of investment funds

Here you can set the starting year of the project and its duration

You can define here prospective values, such as projected inflation rate

discount rate which is used for LCOE calculation, or aging hypothesis

Here you enter income dependent expenses such as taxes or dividends

Pvsyst allows to define detailed depreciation parameters for the system

For this example we set a simple constant depreciation on 20 years with a residual value at the end of the project.

Please see help for more details about depreciation definition and calculation in PVsyst.

In this part of the dialogue you can define in detail the distribution of funds used for the investment

You can define up to 3 loans with different properties

This chart displays the distribution of the investment funds

Total yearly cost and LCOE, which means levelized cost of energy

Are automatically calculated. The resale price should be higher than this energy cost in order to be profitable

Now let us define the resale strategy

PVsyst provides multiple strategies for the resale price

- fixed feed-in tariff, wher the resale price is constant over the year

- for hourly peak/off-peak tariff the resale price depends on the hour of the day

- seasonal tariff means that the resale price is different during summer and winter

- and finally CSV file where custom prices are defined for the whole year in an external file

Let us choose an hourly tariff

First set the peak tariff which is the high price

Then set the off-peak tariff, which is a low price

Select the corresponding time ranges with the clock tool

If you would like to do the calculation with daylight saving time

set the starting dates for summer and winter time. This will allow to make a more precise financial calculation

Set the other resale parameters

Now let us see the financial results of your system

Costs of the system are calculated and summarized according to the inputs

The profitability of the system is detailed here. You can see the payback period

which is the duration needed for your project to be profitable

Annual results are available in this table

Calculation methods are detailed in the PVsyst help

You can also display a yearly graph for the net profit,

or for the cumulative cash flow

You can also visualize the distribution of the expenses for each year of the project
