The abbreviations on the label, explained.
You do not need to memorise the acronyms. This glossary explains the values on panels, stations and batteries in plain English so the calculators and the Ireland regional checks make sense together.
Power and energy are different facts
Watts is the rate of energy use at a moment. Watt-hours is the stored or consumed amount over time. A 1,000W output for one hour uses 1,000Wh — usable energy after losses is lower than the label.
Panel letters describe the operating window
Vmp is the voltage while the panel delivers power and must sit inside the station’s working range. Voc is the no-load ceiling and rises in cold weather. Imp and Isc describe current behaviour and cable requirements.
