Bill of materials

Estimated cost of your energy system

The Bill of Materials (BOM) lists selected system components and materials for your energy system installation, and allows you to manually add labor costs and any other relevant expenses, helping you build a complete and accurate project cost estimate.

It is displayed at the top of the main menu (CAPEX), and you can access its configuration by clicking this field or via the System menu.

Preparing your capital expenditure

When you open the BOM table for the first time, it will be pre-filled with the materials from the current energy system configuration, with all prices set to zero. You can start adding prices to the existing items directly in the table. Editable fields are highlighted in blue, and fields with missing values are highlighted in orange.

The BOM table updates automatically every time you perform changes to the energy system, recalculating the prices per unit for every item. You need to define the prices only once per energy system.

1. The quantity used in the design is filled in automatically.

2. You can add the number of spare items if required. No spares are added to the table by default.

3. Total required item quantity (included in the system + spare).

4. Price per unit definition. Fill in the prices for all items in the BOM. Units are displayed in the previous column.

5. Total price to purchase items required in the system + spares.

Note: Proceed with adding prices to all items to get best-possible CAPEX estimate.

Adding further cost to the BOM

The table provides only items included in the design, but does not provide labour or other expenditures. You can add these manually based on our requirements to account for all known costs apart from installation materials. Click the “Add item” to the right and proceed with adding a new item to the table:

1. Fill in all details:

   • Item name

   • Required quantity

   • Spare quantity (if required)

   • Price per unit

2. After you fill in the details, click the “Add” button to add it to the table. Using the dedicated buttons, you can edit or delete custom items as needed.

Note: All added items are displayed in the table under the Custom category.

Tip: You have 5 seconds to revert the deletition of a custom item.  

Confirming your changes

Every time you make changes to the BOM table, you must apply the changes. These are not applied automatically. If you quit the BOM before you apply the changes, they will disappear, and you will have to start over.

Apply the change by clicking the “Apply” button.
