Panel power=250 w

Panel area=1.65 m^2

Panel power/Panel area=power/m^2

i.e.panel power/panel area=260w/1.65m^2=151.15w/m^2

25% loss during pv generation and conversion

conversion efficiency=18%

(Energy demand/Annual full sun hours)/Efficiency=pv system size

Module power=250 watts*4.4 sun hours per day=1100wh/day

Here's a formula for calculating the solar panel's power output.

Solar panel watts x average hours of sunlight x 75% = daily watt-hours.

250 watts x 4.4 hours x .75 = 1100 daily watt hours

System power/Module power=number of modules

1100/250=4.4
