2. Overall information Photovoltaic collector
Probably will be one of the main energy source in the future

3. Selecting TRNSYS component

4. Model parameters

7. Model in excel
The global formula to estimate the electricity generated in output of a photovoltaic system is :
E = A * r * H * PR
E = Energy (kWh)
A = Total solar panel Area (m²)
r = solar panel yield or efficiency (%)
H = Annual average solar radiation on tilted panels (kWh/m2)
PR = Performance ratio, coefficient for losses (range between 0.5 and 0.9, default value = 0.75)

8. Comparison/conclusion
Results
TRNSYS 279,3 kWh/year
Excel 261,9 kWh/year
Comparison/conclusion
TRNSYS benefits
Excel benefits
Has a big range of possibilities
Complex system
Has demo version
Environment we are used to
Full version price much lower then TRNSYS
Other applications possible
VBA included

9. Used literature
Info about PV
TRNSYS 16 Mathematical Reference
Building a TRNSYS system

10. Thank you for attention!
