Sažetak
We compared two different models for the implementation of small photovoltaic solar systems in the Croatia. The new prosumer model presented in the new Croatian law on the Renewable Energy Sources and Highly Efficient Cogeneration (OG 100/15) and PV ESCO model which is similar to net metering. The comparison was done on a 15-minute basis and there were compared values of Simple Payback Period (SPP) for different locations and systems size considering electricity demand and market prices. Internal Rate of Return (IRR) and Net Present Value (NPV) were compared for 4 different cases. Conducted comparison showed that PV ESCO model is always more favourable for the owner of PV system in terms of lower SPP and higher IRR and NPV. It has been noticed that for systems higher than 5 kWp use of PV ESCO model is recommended. For smaller systems it is not always clear which system should be used. For smaller systems from 2 to 5 kWp, PV ESCO model has SPP from 7.5 to 13 years and SPP value for the prosumer model is 8.7 to 15 years. This difference is higher when comparing PV system from 6 to 10 kWp. SPP for PV ESCO model, in that case, is from 10 to 13 years and in the prosumer model is from 17.5 to 28 years.
