Elementary school in Buštěhrad – case study ENERGY CONCEPT (PV) Total yearly electric energy consumption model (profile used for design of energy system). Energy consumption during summer holiday is minimal which means for example that produced energy from PV system in these months is hard to be consumed. Installed output of PV system [kWp] Yearly production of energy of PV system [kWh] Yearly usage of energy from PV system in the building Coverage of yearly consumption [%] Yearly delivered energy into the distribution network (not used for own consumption) Yearly take-off from the distribution network [kWh] Investment costs of PV system [CZK]* 1 986 937 66 953 80 000,- CZK 2 1 972 1 873 3 66 016 125 000,- CZK 10 9 861 8 180 12 1 189 59 710 440 000,- CZK 30 29 585 19 166 28 8 940 48 724 1 260 000,- CZK Simulation of PV system performances - results and estimated investment costs
