The SolaX Cloud provides extensive energy and system data. Terms such as yield, self-consumption or autonomy may seem clear, but in practice they often lead to misunderstandings. This article explains the most important metrics in the SolaX Cloud and puts them into context.
An overview of the monitoring system is available in SolaX Cloud: Features, Login & Data Overview.
What data does the SolaX Cloud display?
Depending on system configuration and installed measurement hardware, the following values may be shown:
- PV yield
- real-time power
- electricity consumption
- self-consumption share
- grid import
- feed-in
- battery state of charge
- system status
Not every system displays all values. Scope and accuracy depend on inverter type, meters and storage system.
Yield in the SolaX Cloud
Yield describes the energy generated by the photovoltaic system. It is measured in kilowatt hours and typically shown as:
- daily yield
- monthly yield
- yearly yield
- total yield
Yield only indicates how much electricity was produced, not how it was used.
Power vs Yield: key difference
A common misconception is confusing power and yield.
- Power (kW) is the current electricity production
- Yield (kWh) is the total energy produced over a period
Fluctuating power values are normal and depend on weather, time of day and consumption.
Understanding consumption and self-consumption
Consumption describes the total electricity demand of a household or business.
Self-consumption is the portion of generated solar energy that is used directly in the building or later from the battery.
A high yield does not automatically mean high self-consumption, as part of the energy may be fed into the grid.
Grid import and feed-in
Grid import
Grid import is the electricity drawn from the public grid when the PV system does not produce enough or the battery is empty.
Feed-in
Feed-in is the portion of solar energy that is not used locally and is exported to the grid.
In simplified terms:
PV yield = self-consumption + feed-in
Minor deviations due to measurement differences are possible.
Storage values in the SolaX Cloud
For systems with battery storage, the SolaX Cloud provides additional metrics:
- state of charge in percent
- charging power
- discharging power
The battery increases self-consumption by storing surplus solar energy.
Why do values fluctuate during the day?
Fluctuations are technically normal and result from:
- changing solar irradiance
- varying household consumption
- internal energy management strategies
- charging and discharging cycles of the battery
Snapshots should not be evaluated in isolation.
Autonomy and self-consumption rate
The SolaX Cloud often shows metrics such as:
- degree of autonomy
- self-consumption rate
These values are useful for trend analysis but should not be evaluated based on a single day.
Data delay
Data displayed in the SolaX Cloud is updated with a delay.
This means:
- no guaranteed real-time data
- updates in minute intervals
- daily values are only complete after the end of the day
Completed time periods should be used for reliable analysis.
Common misunderstandings about SolaX Cloud data
- high yield does not mean high autonomy
- low feed-in is not an error
- differences between app and web portal are normal
- short-term fluctuations are system-related
Data should always be evaluated in context.
When is SolaX Cloud data sufficient and when not?
Sufficient for:
- single systems
- private use
- overview of energy flows
- optimizing self-consumption
Limited for:
- multiple locations
- cross-manufacturer analysis
- precise billing
- external reporting
Frequently asked questions about SolaX Cloud data (FAQ)
Why do yield and consumption not match?
Yield describes generated energy, consumption describes used electricity. Part of the generated energy is fed into the grid or stored.
Why does my electricity meter show different values?
Grid operator meters are legally calibrated. The SolaX Cloud uses internal measurements that may differ in timing or method.
Why don’t I see consumption in the cloud?
Without appropriate measurement hardware, consumption cannot be displayed correctly.
Is the data real-time?
No. Data is updated with a delay and is intended for analysis, not second-by-second monitoring.
