Tariff Settings
The tariff settings define how grid electricity is priced within solarVis. Every financial output generated inside a project depends on the tariff logic configured on this page.
Purpose of This Page
The Tariff Settings page defines the grid pricing logic used in solarVis.
All financial outputs, including pre- and post-solar bills, energy export compensation, payback period, and inflation-adjusted modeling, depend directly on the tariff configured here.
This page allows you to accurately model real-world utility structures such as fixed charges, minimum bills, tiered rates, time-of-use pricing, solar energy compensation, VAT, and multi-year inflation.
Accurate tariff configuration ensures that feasibility results reflect real grid conditions and regulatory frameworks.
What You Can Do Here
From the Tariff Settings page, you can display the points below:
View all tariffs in a structured table
Search tariffs using the search field
Apply advanced filters using the Filter button
Activate or deactivate tariffs using the toggle
Switch between All Tariffs and Active Tariffs
Create a new tariff
Edit an existing tariff or duplicate it
Delete custom tariffs
Open a detailed tariff preview in a side panel
This allows centralized tariff management across multiple countries, facility types, grid connection types, and regulatory models.

This allows a quick review of the tariff.
Creating a New Tariff
Rate Details
This section defines where and how the tariff can be used.
Required Fields
Name
Currency
Countries
Facility Types
Optional
Description
What These Settings Control
In which countries is the tariff available
Which facility types (Residential, Commercial, etc.) can use it
Which projects and Lead Generator configurations reference it
A single tariff can be assigned to multiple countries and facility types if needed.
The Tariff Name and Description fields will be displayed in the proposal, so they should be written clearly, professionally, and in a client-facing format.
Solar Compensation
This section defines how exported solar energy is treated.
Compensation Mechanisms
Net Metering
Net Billing
Net Billing (Credit Carryover)
Each mechanism changes how energy exports are valued and whether solar credits exist in the system.
Mechanism Logic
Net Metering
Exported energy offsets consumption at the retail rate
Surplus becomes a credit balance
Settlement occurs during the defined true-up period
Solar credits exist
System Effects:
Activates Apply Solar Credits option in Fixed Charges
Doesn’t activate Export Settings (retail offset is implicit)
Net Billing
Exported energy is compensated at a defined export rate
No credit carryover between billing periods
No ongoing credit balance
System Effects:
Doesn’t activate Apply Solar Credits
Activates Export Settings
3. Net Billing (Credit Carryover)
Exported energy is compensated at a defined export rate
Surplus credits roll over to future billing periods
Credit balance can accumulate
System Effects:
Activates Apply Solar Credits in Fixed Charges
Activates Export Settings
True-Up Settings
When a credit-based mechanism is selected (Net Metering or Net Billing with Credit Carryover), additional settings appear:
True-up Period (Monthly or Annual)
True-up Month
Net Surplus Compensation Rate
These define:
When settlements occur
How unused credits are handled
Whether credits expire
How the final surplus is compensated
Export Settings
The Export Settings section appears only when:
Net Billing
Net Billing (Credit Carryover)
It is not visible under Net Metering
What It Controls
Defines how exported energy is valued.
You can configure:
Export Rate Type, such as:
Retail Rate
Retail Rate – Fixed Reduction
Retail Rate – Percent Reduction
Fixed Rate
This determines how energy export compensation is calculated.
Export configuration directly affects:
Post-solar bill calculation
Export revenue
Total project savings
Rates
Fixed Charges
Fixed charges represent recurring, non-energy costs added to the electricity bill.
Click Add Fixed Charge to create a new item.
For each charge, define:
Name
Amount
Billing Period (per month or per day)
Pre-Solar Bill toggle
Post-Solar Bill toggle
How It Works
Apply Solar Credits → If enabled, solar credits can reduce this fixed charge (when credit-based compensation is active)
Pre-Solar Bill → Applies before solar installation
Post-Solar Bill → Continues after installation
The Apply Solar Credits toggle appears only if the selected Solar Compensation mechanism is:
Net Metering
Net Billing (Credit Carryover)
This toggle determines whether accumulated solar credits can offset the fixed charge.
This allows modeling:
Service fees
Grid connection energy charges
Subscription costs
Fixed charges are included in both monthly and long-term financial calculations.
Minimum Bill
Defines the minimum amount payable per billing period.
If calculated energy charges fall below this value, the system enforces the defined minimum.
This is essential in markets where utilities require a fixed minimum payment regardless of energy consumption.
The Minimum Bill rule is applied to the pre-solar bill calculation, ensuring the minimum payment requirement is enforced before solar energy savings are considered.
Rate Periods & Tiers
This section defines energy-based pricing structures.
Click Add Period to create a new rate period. Each period can contain multiple tiers.
For each tier, define:
Consumption range
Maximum kWh
Rate per kWh
Adjustment value
Calculated total rate
Consumption within each tier is charged at that tier's rate.
This structure supports:
Block (tiered) pricing
Seasonal pricing
Multi-period rate structures
Ensure tier ranges do not overlap.
Defined periods are later mapped inside the Time-of-Use Schedule.
Time-of-Use (TOU) Schedule
Assigns hourly pricing logic to defined rate periods.
Configuration is separated into:
Weekday Schedule
Weekend Schedule
For each:
Month of the year
Hour of the day
You should assign a period number to the hourly cells.
The graph displays:
12 months
24 hours per day
Each hourly cell references a defined rate period.
This enables modeling:
Peak hours
Off-peak hours
Seasonal peak variations
The Time of Use schedule directly impacts grid electricity purchase cost and savings calculations.
Demand Charges
Models kW-based peak-demand or average-demand billing structures. Click Add Demand Charge to configure.
For each demand charge, define:
Name
Charge Type (Peak Demand or Average Demand)
Effective Days (Weekdays / Weekends)
Charge Rate per kW
Minimum Demand
Maximum Demand
Supports modeling of:
Peak demand penalties
Capacity-based billing
Demand charges are included in:
Feasibility analysis
Bill comparison outputs
Long-term projections
Financial Parameters
VAT Rate
Define the VAT percentage applied to electricity charges.
VAT is included in total pre-solar and post-solar bill calculations when applicable.
Inflation Rates
Define annual inflation assumptions.
Inflation is applied to:
Utility prices
The inflation rate's impact is reflected in long-term financial outcomes such as total savings and payback period.
Editing a Tariff
To modify a tariff:
Open the action menu.
Click Edit.
Update the desired configuration sections.
Click Save Changes.
You can modify all steps directly within the tariff configuration.
Changes apply to future project calculations referencing this tariff.
Duplicating a Tariff
To duplicate a tariff:
Open the action menu.
Click Duplicate.
A new copy is created with a Custom label.
This is recommended when:
Adapting a national tariff to a regional variation
Duplicating prevents unintended changes to default or shared tariffs.
Deleting a Tariff
Custom tariffs can be deleted via the action menu. System or default tariffs may be protected from deletion to ensure platform stability.
Deleting a tariff removes it from the Active Tariffs list, meaning it will no longer be available for selection in future projects.
Accurate tariff configuration is critical for reliable feasibility and proposal results. Incorrect or incomplete tariff settings will disrupt Return on Investment and customer-facing financial outputs.
