Production Costs - Standard Models
Due to the present fluctuation of currency rates and unstable energy prices, the cost calculations below
shall be considered indicative only. The values chosen for the electricity price ($0.225/kWh), interest
rate (10% per annum) and (10-years) of amortization may not correspond to those valid for your project.
However, precise calculations for actual projects can be performed upon request.
