Consumption
The page defines how electricity consumption and electricity regulation rules are modeled for feasibility and financial calculations in solarVis.
Purpose of This Section
The Consumption page is the foundation of all feasibility and financial outputs. Every calculation, such as self-consumption, grid import and export, savings, and payback period, depends on the accuracy of the data defined here.
What You Can Do Here
In the consumption page, you can:
Define daily, monthly, or annual electricity consumption values
Choose from predefined consumption profiles or create custom usage patterns
Upload detailed hourly consumption data using an Excel file
Choose applicable electricity prices and regulations based on the project location for On-Grid or Zero Injection projects
Determine preset appliances or add new ones for Off-Grid projects
Select the electricity purchase price, the electricity export price, and the electricity offset prices
Apply VAT and inflation rate
Choose the applicable project currency
Synchronize consumption settings across multiple project designs
Consumption Page Structure
This page contains three main tabs:
Energy Consumption
Defines how much electricity the facility consumes and how consumption is distributed throughout the day and across months.
Here, you can:
Enter monthly or annual consumption values
Select or customize a consumption profile
Control daily and seasonal usage patterns
This data is used to calculate self-consumption, grid usage, and energy balance.
Electricity Prices and Regulation (On-Grid / Zero Injection Projects)
Defines how electricity is priced and regulated for on-grid or zero injection projects.
Here, you can configure:
Electricity purchase, export, or offset prices
VAT and other applicable rates
Currency
Country-specific regulatory rules or global regulatory rules
These settings ensure that financial calculations comply with local market rules.
Appliances (Off-Grid Projects)
Defines electricity usage for off-grid projects based on electrical appliances.
Here, you can:
Add electrical appliances
Define their count, usage duration, and nominal power
Automatically calculate total energy consumption
This tab is used only for off-grid system designs.
Together, these tabs allow solarVis to accurately calculate self-consumption, the electricity export amounts, savings, payback period, and all related financial outputs.
This page uses auto-save, so any changes you make are saved automatically.
Upload Consumption Profile
A project in solarVis can use either manually entered consumption values or a detailed hourly consumption profile.
By using the Upload Consumption Profile action, you can upload an hourly consumption file and apply it to the design. This allows solarVis to use real consumption data instead of estimated values, improving the accuracy of feasibility and financial calculations.
The uploaded profile is used directly in simulations, and the system automatically reflects the derived daily and monthly values on this page.
Sync Current Changes to All Designs
A project in solarVis can include multiple design versions.
By clicking Sync Current Changes to All Designs, you can apply the current consumption and regulation settings to all design alternatives within the project.
This ensures that all designs use the same consumption baseline, making it easier to compare different system layouts and equipment selections.
