### View profits for different time periods

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

* **Day / Month / Year**: View profits for the specified date, month, or year
* **All**: View cumulative profits since system installation (date selector 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 profits page, you can see**the self-consumption rate card**, which intuitively shows the destinations of PV electricity:

* A donut chart displays the self-consumption rate for the current time range
* Clearly distinguish PV power flows:
  * Home load
  * Battery storage
  * Fed into the grid

This helps you judge: of the generated electricity, how much you used yourself.\
\
**Renewable achievements:** The same card also displays your Renewable achievements:

* Reflects the proportion of household electricity coming from renewable sources or the battery within the current time dimension
* Helps you intuitively feel the contribution of green energy to energy independence and daily life

### Solar profits

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

* **Self-consumption profit**
  * Using PV electricity to directly power the home or charge the battery
  * Calculated as the saved electricity cost using the purchase price for the corresponding period
* **Feed-in profit**
  * Surplus electricity sold to the grid
  * Calculated by the feed-in tariff for the corresponding period

The system performs the calculation automatically; no manual intervention is required. Tip:

* Profit calculations are based on the tariff plan you configured
* If profits are displayed abnormally or missing, first check[Public tariff plans](#gong-gong-shi-ye-feilji-hua)(click the gear icon in the top right) whether it is complete and whether the device is online

### Public tariff plans

Profit calculation depends on the **buy electricity price** and **sell electricity price**. These prices are usually found on your utility bill. After entering the system, please follow the guide to complete your tariff plan to ensure profit calculations match actual conditions. Public tariff plans currently support three pricing modes:

* Fixed price
* Time-of-use pricing
* Dynamic pricing (price data sourced from[EPEX SPOT](https://www.epexspot.com/en/market-results))

{% hint style="info" %}
Currently dynamic pricing information sources: Germany, Poland, the Netherlands, Belgium; we will continue to expand supported countries.
{% endhint %}

#### **Start setting up your tariff plan**

#### **1. Set a fixed price**

* Fixed price is suitable for 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 profits for the whole day, no additional configuration needed.

#### **2. Set Time-of-Use (TOU) pricing**

* Suitable for regions where prices vary by **season / weekday / time period** .
* TOU pricing consists of two parts:
  * Time periods: describe when prices change
  * Price types: describe the price level for that period, including Peak, High, Standard, Low, Off-peak and custom types
* Start setting TOU pricing
  * Choose time factors
    * Seasons: create multiple seasons using “start date - end date”; months of different seasons must not overlap
    * Weekday / weekend: distinguish here if weekday and weekend have different prices
  * Set time period ranges
    * Divide a day into different time periods.
    * Each period must be assigned a price type.
    * Different periods must not overlap.
  * Set price type rates

    * Each price type (such as Peak, High, etc.) needs a corresponding buy price and sell price

#### **3. Market trading prices (also called dynamic pricing)**

Only applicable to countries or regions where prices**fluctuate hourly**. Currently supported only for **the Netherlands, Belgium, Poland, Germany**users, more regions are being added!

Prices are[ EPEX SPOT ](https://www.epexspot.com/en/about)published in real time and provide 24-hour prices for the next day each day.

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

<div align="left"><figure><img src="https://3500615383-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FF8UZRgRjjg1mF4YbfRnx%2Fuploads%2Fgv6xL3eEYHVkLDw0egC5%2Fimage.png?alt=media&#x26;token=9884e905-cd18-459c-a952-1e41c55c6eec" alt="" width="188"><figcaption></figcaption></figure></div>

**How does Market trading pricing (EPEX SPOT) work?**

* EPEX publishes the next day’s hourly buy/sell prices every afternoon
* The system automatically syncs this data
* Your profit calculations 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 automatically records and calculates for you without any manual operation.<br>

{% hint style="info" %}
**Frequently asked questions:**

* Why do prices differ every day?&#x20;
  * EPEX prices vary in real time based on generation costs, weather, demand and other factors; this is the mainstream market mechanism in Europe.
* Why are nighttime prices lower?&#x20;
  * Prices drop when demand is low; prices rise when demand is high—this is normal market behavior.
* Are dynamic prices stable?&#x20;
  * Prices fluctuate, but energy storage systems can use the volatility to reduce costs or increase profits.
