Profits

The profit feature is based on actual operating data from the AlphaESS system and helps you understand the economic value created by your solar and storage system over different time periods. The system compiles your generation and consumption behavior and calculates profits based on the tariff plan you configure.

• Self-consumption rate and renewable achievements

Tip: Earnings data are estimates intended to help you understand trends and comparisons; the final bill is subject to settlement by the utility company.

View earnings at different times

You can use the time selector at the top of the page to view earnings performance by different dimensions:

• Day / Month / Year：View earnings for the specified date, month, or year

• All：View cumulative earnings since system installation (date selection is not shown in this mode)

After selecting a time range, all data and charts on the page will update synchronously.

Self-consumption rate and renewable achievements

Self-consumption rate: On the earnings page, you can seethe self-consumption rate card, which intuitively shows where PV electricity goes:

• A donut chart shows the self-consumption rate for the current time range

• Clearly distinguishes the flow of PV generation:

  • Household load

  • Battery storage

  • Fed into the grid

This helps you judge: how much of the generated electricity you consumed yourself. Renewable achievements: The same card also displays your renewable achievements:

• Reflects the proportion of household electricity from renewable energy or the battery within the current time dimension

• Helps you intuitively feel the contribution of green energy to energy independence and daily life

Solar earnings

The solar earnings card will show an estimate of the “value of solar generation” for the selected time range, composed of two parts:

• Self-consumption earnings

  • Using PV electricity to directly power the household or charge the battery

  • Calculated as the electricity cost saved using the purchase price for the corresponding periods

• Feed-in earnings

  • Excess electricity sold to the grid

  • Calculated based on the feed-in tariff for the corresponding periods

The system will complete the calculation automatically without manual intervention. Tip:

• Earnings calculation is based on the tariff plan you configured

• If earnings are displayed abnormally or missing, please first checkPublic tariff plan(click the gear icon in the upper right) whether it is complete and whether the device is online

Public tariff plan

Earnings calculation depends on the buy electricity price and sell electricity price. These prices can usually be found on your utility bill. After entering the system, please follow the guide to complete your tariff plan to ensure earnings calculations match the actual situation. Public tariff plans currently support three types of pricing models:

• Fixed price

• Time-of-use (TOU) pricing

• Dynamic pricing (price data sourced fromEPEX SPOT)

Current dynamic price information sources: Germany, Poland, the Netherlands, Belgium; we will continue to update supported countries.

Start setting up your tariff plan

1. Set fixed price

• Fixed price applies to regions where the price is the same all day.

  • Entry: select the “Fixed” mode

  • Required input:

    • buy electricity price

    • sell electricity price

• The system will use the same price to calculate earnings for the whole day, no additional configuration needed.

2. Set time-of-use (TOU) pricing

• Applicable where prices vary by season / weekdays / time periods .

• Time-of-use pricing consists of two parts:

  • Periods: describe when price changes occur

  • Price types: describe the price level for that period, including Peak, High, Shoulder, Valley, Deep-valley and custom types

• Start setting TOU pricing

  • Select time factors

    • Seasons: create multiple seasons by “start date - end date”; months of different seasons may not overlap

    • Weekdays / weekends: distinguish here if weekday and weekend prices differ

  • Set period ranges

    • Divide a day into different time periods.

    • Each time period must be assigned a price type.

    • Different periods must not overlap.

  • Set prices for price types

    • Each price type (such as Peak, High, etc.) requires setting the corresponding buy price and sell price

    

    

    

    

    

After configuration, the system will automatically calculate your overall earnings based on the price type matched to each period.

3. Market pricing (also called dynamic pricing)

Only applicable to countries/regions where pricesfluctuate hourly, currently only supported for Netherlands, Belgium, Poland, Germanyusers, more regions are being expanded!

Prices are EPEX SPOT published in real time, providing 24-hour prices for the next day each day.

If your household electricity contract type is dynamic pricing, just choose Market Pricing - EPEX SPOT in the tariff plan; the system will automatically fetch day-ahead prices from EPEX every day without manual entry.

How does market pricing (EPEX SPOT) work?

• EPEX publishes the next day's hourly buy/sell prices every afternoon

• The system automatically synchronizes these data

• Your earnings calculation will be updated hourly based on real market prices

In other words: you buy and sell electricity each day at real market prices. The system will automatically record and calculate for you without any manual operation.

Frequently Asked Questions:

• Why do prices differ every day?

  • EPEX prices change in real time based on generation costs, weather, demand, and other factors; this is a mainstream market mechanism in Europe.

• Why are nighttime prices lower?

  • Prices fall when demand is low and rise when demand is high; this is normal market behavior.

• Is dynamic pricing stable?

  • Prices fluctuate, but energy storage systems can take advantage of the fluctuations to reduce costs or increase earnings.
