Attractiveness of Self Consumption
Example:
a small consumer with 500kWp installed PV-Power in
Turkey
1. Consumer with 15$cent* electricity price
2. FiT Tariff 0-133$/kWh
> 100% Feed In
750.000kWh/a x 0.133$c= 99.750$
> 100% Self Consumption
750.000kWh/a x 0.15$=112.500$
! Difference of 12.750$/a

Outlook
> The attractiveness of a self consumption system depends on
following factors:
> Ratio between Electricity production/electricity
consumption
> Individual load profile and of course
> Current electricity tariff!
> Commercial self consumption has larger effects:
Higher contribution to the grid stabilization with PV systems, which
are closer to the main consumer hot spots.
> A close study is necessary. Since with the current electricity tariff
might be not attractive for self consumption.
! Intelligent Optimization allows higher amount of renewable
energies to the existing grid.
SMA Solar Technology AG
! Self consumption advantage increases with every electricity price
