Electricity Prices and Regulation (On-Grid / Zero Injection Projects)
It defines how electricity is priced and regulated for on-grid & zero injection projects, including electricity tariffs, export and compensation rules, VAT, inflation and market-specific settings.
Purpose of This Tab
The Electricity Prices and Regulation page controls how electricity consumption and solar production are converted into money. It determines how electricity purchased from the grid, self-consumption, electricity exported to the grid, and compensation are calculated.
All financial outputs, such as savings, cash flow, and payback period, depend directly on the parameters defined here.
SolarVis automatically selects the most appropriate regulation based on the project’s location and facility type. Users can review the assigned regulation or change it and adjust tariff and financial parameters when required.
What You Can Do Here
In this tab, you can:
Review or change the automatically selected Tariff
Configure electricity purchase, electricity export, and offset prices
Adjust VAT and multi-year inflation assumptions
Select the calculation currency
Retrieve up-to-date electricity prices for supported regions
Sync pricing settings across all design versions in the project
Save all changes using the Save Changes button
How It Works
The system loads the regulation based on the project configuration.
Tariff parameters populate the Tariff Details section.
Energy simulation results are combined with:
Purchase price
Export price
Compensation mechanism
VAT
Inflation assumptions
Any updates made here instantly recalculate all financial outputs after clicking Save Changes.
Regulation Selection
The Select Regulation field defines the market rules applied to the project. SolarVis determines the applicable regulation automatically using:
Project location
Facility type (residential, commercial, industrial, etc.)
Grid connection type (On-Grid or Zero Injection)
All financial outputs in the project depend on this selection.
You can manually change the regulation if needed. When a regulation is selected, its tariff structure loads automatically into the Tariff Details panel.
Global Regulation is the default (fallback) tariff applied when no active tariff exists for the project’s location and facility type.
It requires manual configuration of all tariff components and parameters, giving users full control over pricing logic, compensation rules, and financial assumptions.
It functions like creating a fully custom tariff from scratch, allowing complete flexibility to define the structure according to specific market or contractual needs.
Editing or Creating Regulations
At the bottom of the dropdown, a helper link is provided:
“To activate, edit, or create new tariffs, visit the tariff settings page.”
This link redirects to the Tariffs management page, where users can:
Create new tariffs
Modify existing tariff structures
Activate or deactivate tariffs
Only active regulations appear in this dropdown. Changes made in the Tariff Settings page become available here after activation.
Get Latest Electricity Prices
For supported regulations, users can click Get Latest Electricity Prices to automatically retrieve updated tariff data.
This ensures:
More accurate financial projections
Alignment with current market prices
Reduced manual data entry
Sync Current Changes to All Designs
Applies the current tariff and regulation settings to all designs within the project, ensuring consistent financial calculations across every design scenario.
Tariff Details
This section contains all editable financial inputs linked to the selected regulation.
All modifications must be confirmed using the Save Changes button. Updates made here apply only to the current project.
Rate Details
Defines where the tariff can be used.
Set Name, Currency, Description
The Countries and Facility Types options are locked here because they were defined when the project was created.
Solar Compensation
Defines how exported solar energy is handled.

Fixed Rate
Directly affects energy export revenue and savings.
It is only visible for Net Billing models
Rates
Fixed Charges → recurring, non-energy costs
Minimum Bill → Enforced minimum payment
Rate Periods & Tiers → Tiered or period pricing
TOU Schedule → Hourly/Monthly peak/off-peak mapping
Demand Charges → kW-based peak-demand or average-demand billing structure
Financial Parameters
VAT Rate → Applied to electricity charges
Inflation Rates → Escalates utility prices over time
Impacts long-term savings, payback, and return on investment.
Where to Configure Full Tariff Structure
The Tariff Details section in this document includes only the key parameters required for project-level financial configuration. For detailed tariff structure setup, please refer to the Tariff Settings page.
The Tariff Settings page is where tariff frameworks are created, structured, and maintained at the system level.
