The difference between kVA and kW is as follows:
-
kVA (kilovolt-ampere) is a measure of apparent power, while kW (kilowatt) is a measure of real power.
-
In DC circuits, kVA is the same as kW, but in AC circuits, they differ.
-
kW represents the actual power consumption of devices, while kVA is used for sizing electrical equipment.
-
The basic formula for kVA is V x I, whereas for kW it is V x I x power factor.
​
Photovoltaic systems can last for more than 20 years, and some arrays come with warranties for up to 30 years.
The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer.
Most photovoltaic solar panels will last 25 years before they begin to noticeably degrade, and most solar panel companies will provide a standard 25-year warranty for the expected life expectancy of the solar panels.
The lifetime of the entire system might be as much as 40 years.
