Can you tell me what the annual production reduction should be using the Conergy PH260P solar panels, and any idea how or why this was not entered into this particular estimate given? Would the program not error someone not providing some info here? I am unfamiliar with PVsyst and don't plan on using it but am reading an energy estimate for a solar project for our city and this seems to be very important missed information that affects the economic realities. thank you following is copied from the document PV Field Orientation tilt 41° azimuth 0° PV modules Model Conergy PH 260P Pnom 260 Wp Long term balance and Running conditions Annual sale tariff depreciation 0.0 % / year Annual production reduction 0.0 % / year Feed-in tariff Warranty over 25 years Tariff reduction after contractual warranty 0 % Loan duration (payment of annuities) 25 years
