Comparing solar power production: simulated results by homer and actual provided power
I´m trying to model the energy system of a certain city.
The wind speed is downloaded from the NASA database as well as the GHI. Comparing the solar power production calculated by Homer with the actual provided solar power in the city there is far too much production in winter for this region. That doesn´t make much sense. I already checked the scaled data, but this value is right and the geografical input is also correct.
Is there another parameter which influences the results this way?
NASA's resource is based on the average values of historical data obtained over a period of 5-10 years. So it wouldn't be very precise compared to the latest historical data. We are working on updating the HOMER's connection to NASA's database so you would be able to download the latest data.
