Frequently Asked Question Related To Solar

What is the unit of electricity?

Electricity is measured in kWh (Kilo Watt Hour). It is the amount of electricity consumed by an appliance in a specified period. For example, 100W bulb * running for 1 hour = 100Wh which is equal to 0.1 kWh (unit).
Your electricity bill mentions the kWh (Units) consumed by you in your billing cycle.

 

What is the difference between kW & kWp in relation to Solar PV systems?

KWp is the nameplate rating of Solar PV modules and kW is the actual power delivered to the load. For instance, a 0.3kWp (300Wp nameplate) module under ideal conditions (25 degrees C and 1000 watts per sq. metre radiation, etc.) will give an output of 0.3kW. However, in real life weather conditions, the output will be lower than the nameplate rating which is denoted in kW.

What is the difference between kW and kVA?

Both are units of power , kW is active power whereas kVA is the apparent power because only a certain portion of the available kVA can be utilized kVA=kW+kVAR. If you take a mug of coffee, you can see its two component coffee+ foam. Here the portion of coffee is active power(kW), foam is reactive power caused by certain electrical equipment, and coffee + foam is apparent power (kVA).
