1 Case study: Example of PV Solar Field in NOVO PRO Expert Program This case study compares simulation results from NOVO PRO with the plant actual performance for five solar plants. These plants have their actual operating data available to the general public on-line, courtesy of the plant owners.

Note Jun & Jul 2018 data are taken out due to the inverter outputs are abnormally small.

The biggest deviation in 2014 could be due to plant instability at its commissioning stage.

13 Conclusions 1. PV Solar Field in NOVO PRO is very user-friendly. 2. Only six inputs by the users each of the five plants. 3. Built-in databases (weather database, irradiance database, PV panel library, etc.) are all available within the program. 4. Annual yields from NOVO PRO match with plant actual figures very well (within ±5%) for all the five plants. 5. NOVO PRO s results are even better than the onsite programs estimation for the first two plants, in which onsite prediction data are available.
