ENERGY, EFFECT, CYCLE OG KWH?


Wondering what the terms in our industry mean?

Term Unit Description
Effect kW Performance from solar cells, battery pack or generator.
Energy kWh Energy [kWh] = Power [kW] * Time [h]
Example : If the generator runs optimally for one hour with a power of 128 kW, 128 kWh of energy is produced.
Installed power solar cells kWp
p = peak
How much power the photovoltaic system has and will be able to deliver under good conditions.
Good conditions are defined on the basis of STC (standard test conditions).
Yield factor kWh / kWp Energy production in relation to installed kWp. In southern Norway, this is between 800-1000 kWh / kWp.
SoC% % State of Charge. Expressed in% of degree of filling of the battery (how full the battery is). Scale from 0-100%.
Death % Depth of Discharge. For our batteries, this is 100%, which means that 100% of the stated battery storage capacity is actually available. If the battery pack has 173 kWh stated as storage capacity, the battery will have 173 kWh actually available.
Cycle Number A cycle is a charge from 0% to 100% and a charge to 0% again.
SoH % State of Health. Battery condition today compared to battery condition at time of production. This means that SoH will be 100% when the battery is installed.
