EPC

Here you can detail the project costs and selling price in the EPC mode.

These parameters should always be specified without taxes since taxes are automatically applied during the simulation.

These parameters are always taken into account for the economic analysis of the project: cash flows, savings, investment recovery, and profitability.

Installation Costs

Installation costs, also known as costs of goods sold (COGS), are those associated with the start-up of the project and include, among others, the expenses related to materials, labor, and administration.

These costs are necessary for conducting an economic analysis of the project.

You can define them in the following ways:

• Total cost: the final value of the installation cost. If you enter 10 000 €, this will be the total cost used.

• Cost per size: based on the size of the installation. If you enter 1 €/Wp for a 10 kW installation, the total cost will be 10 000 €. Additionally, if the installation includes storage, you can define a cost per capacity. For example, taking the previous 10 kW installation at 1 €/Wp and adding 5 kWh of storage with a cost of 2 €/Wh, the total cost will be: (2 €/Wh * 5 000 Wh) + 10 000 € = 20 000 €.

• Cost per module: based on the number of modules in the installation. If you specify a cost per module of 400 € and the installation has 10 modules, the total cost will be 4 000 €.

These costs are for internal use only, so they will not be displayed in the generated proposal. Instead, your client will be able to see the final selling price (including the margin).

INFO

If you do not specify installation costs, the economical analysis cannot be executed unless you define parametric default values in the Settings menu.

Selling Price

To establish the selling price of the installation, you can specify a gross margin ratio, which indicates the percentage of the selling price that you retain as gross profit.

For example, for an installation with a cost of 8 000 € and a gross margin of 20 %, the selling price of the installation will be 10 000 €.

The gross margin is for internal use only, so it will not be displayed in the generated proposal. However, your client will be able to see the final selling price (including the margin).

INFO

If you do not specify a gross margin nor define parametric default values in the Settings menu, the selling price of the installation will be equal to the installation cost, i.e. a gross margin of 0 % is assumed.

Operating Costs

Operating costs include all expenses associated with the continuous operation and maintenance of the system. These costs can be broken down into:

• Annual maintenance: may include reviews, cleaning, or replacement of components.

• Annual monitoring: may include visualization and alert services to ensure the proper functioning of the system.

These costs are reflected in the Notes section of the generated proposal.

INFO

You can set a delay in the application of these costs. For example, if maintenance and monitoring costs are 100 € in total and there is a 2-year delay, it means that from the 3rd year onwards, an annual cost of 100 € will be applied.
