Wondering what these terms mean in our industry?
| Term | Unit | Description |
|---|---|---|
| Effect | kW | Output from solar cell panels, battery pack or generator. |
| Energy | kWh |
Energy [kWh] = Effect [kW] * Time [h] |
| Installed effect solar cells | kWp p=peak |
How much effect a solar power plant has and will be able to deliver under ideal conditions. Ideal conditions are defined from STC (Standard Test Condition). |
| Yield Factor | kWh/kWp | Energy production concerning installed kWp. In Southern Norway, this factor is between 800 – 1000 kWh/kWp. |
| SoC % | % | The State of Charge. It is expressed in % of much charge or effect the battery has against its maximum charge on a scale from 0 – 100%. |
| DoD | % | Depth of Discharge. For our batteries, this is 100%, meaning that 100% of provided battery storage capacity is available. If the battery pack has 173 kWh listed as its storage capacity, the battery has 173 kWh available. |
| Cycle | count | One cycle is a change from 0% to 100% and dischaged to 0% again. |
| SoH | % | The State of Health. The battery’s capability presently compared to the battery’s condition at the time of production, which means that SoH will be 100% when the battery is new. |
