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] Ex: If a generator is working optimally for one hour with an effect of 128 kW, then 128 kWh energy is produced in an hour.
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.
