In the article on Electric Vehicle charging this paragraph appears…
‘Generally, it will take a full day to charge an average EV from 20% to 80% using a common 6.5kW rooftop solar system’
This term 6.5kW (or maybe 10kW) is used a lot in articles on home Solar installations.
Surely this is misleading because the correct terminology is 6.5kWpeak - this being the best that the panels could ever produce in a laboratory environment or in the middle of a desert in Chile at the best time of day on the best day of the year. It is nothing to do with the amount that you would actually produce on your house.
People tend to relate this 6.5 figure to either the kW that will be generated each hour average or is somehow is related to the charging of the Batteries, which of course is measured in kWh.
How should we best describe the ‘size’ of a house installation?
