Energy Consumption

The page defines how and when electricity is used at the facility. The data entered here is used to calculate self-consumption, export potential, system sizing, all feasibility, and financial results.

Purpose of This Page

This page allows users to model electricity consumption behavior using daily usage patterns and monthly or annual energy values.

Consumption is defined in two dimensions:

  • Daily distributionwhen electricity is used during a 24-hour day

  • Monthly volumehow much electricity is used throughout the year

Together, these inputs determine how well the solar system matches the facility’s demand and directly affect self-consumption, the electricity export levels, and financial returns.

What You Can Do Here

Here, you can:

  • Select a predefined daily consumption profile or create a custom 24-hour consumption distribution

  • Define electricity consumption on a monthly or annual basis

  • Upload detailed hourly consumption data using an Excel file

  • View consumption charts in real time

The chart on the right visualizes the consumption pattern in real time, helping users validate their inputs.

  • Apply the same consumption settings to all design versions in the project

Daily Consumption

Daily consumption defines how electricity usage is distributed across 24 hours.

This distribution plays a critical role in:

  • Calculating self-consumption

  • Matching solar production with demand

  • Estimating electricity export to the grid

Consumption Profile

Users can choose a preset daily consumption profile or create a custom profile.

Available preset profiles include:

  • Family Day Consumption

  • 1–2 Person Family Consumption

  • Retiree or Home Office Consumption

  • Night Time Home Consumption

Each preset represents a typical hourly load curve.

Selecting a profile automatically updates the daily consumption chart.

Custom Daily Distribution

When Custom is selected, users can manually define how consumption is distributed across the day.

  • Values are entered as percentages per time range

  • The total must equal 100%

This option is useful for modeling:

  • Industrial or commercial operations

  • Seasonal or vacation homes

  • Facilities with night shifts

  • EV charging behavior

  • Industrial night shift patterns

Monthly Consumption

Monthly consumption defines the total energy used by the facility per month. This value is required for feasibility and financial calculations.

Consumption Profile

The monthly Consumption Profile determines how total consumption is distributed across the year.

Two options are available:

  • Constant Consumption

When Constant is selected, the same consumption value is applied to every month.

Best suited for:

  • Residential users

  • Facilities with stable year-round energy usage

  • Custom Consumption

When Custom is selected, users can enter individual kWh values for each month from January to December.

Recommended for:

  • Facilities with seasonal usage

  • Agricultural or tourism-related projects

  • Heating or cooling–driven consumption patterns

Period Selection

The period dropdown allows users to choose:

  • Monthly

When the Monthly option is selected, the entered value represents consumption per month.

  • Annual

When the Annual choice is selected, the entered value represents total annual consumption. SolarVis distributes this value across months based on the selected monthly profile.

Upload Consumption Profile

Instead of manually defining consumption, a detailed hourly consumption file can be uploaded to model real usage behavior.

By using this action, you can import an Excel file that contains hourly consumption data.

This method allows solarVis to use real measured data rather than estimated distributions and significantly improves the accuracy of feasibility and financial calculations.

When a file is uploaded:

  • The system reads hourly consumption values from the file

  • Daily distribution is automatically derived from the hourly data

  • Monthly consumption values are calculated based on the uploaded dataset

  • All simulations use this profile directly instead of manual inputs

This approach is especially useful for:

  • Projects with smart meter or SCADA data

  • Commercial and industrial facilities

  • Projects where accurate load matching is critical

  • Validating proposals with real consumption history

To upload a file:

  • Click the Upload Consumption Profile button

  • Download the template file if needed

  • Prepare your data in the required hourly format

  • Upload a single .xlsx file

Once uploaded, the system overrides manual daily and monthly inputs and uses the uploaded data as the primary consumption source.
