What is the efficiency?
How would you calculate?
Solar Power Professional Development Course for Engineers Sizing a PV System Calculate the required PV power capacity based on – the energy consumption of the load and – the number of peak sun hours per day (at 1000W/m2) Example : Annual energy consumption of the load = 9125 kWh/year = 25 kWh/day Let’s say 50% of energy consumption will be provided by PV PV system energy output = 12.5 kWh/day Now determine the number of peak sun hours available per day at the installation location. There are two ways of doing this…
