Many thanks for your reply. I already made the change of "Max Usage" 1 to 1E+38 and the results seem to me are great. It is my first time using SAM. In Honduras, my country of origin, for the moment there is no economic incentives, there is no purchase of the extra generated energy by the PV system, or payment for the energy consumed from the PV system. The only incentive is the energy that is no to consume from the grid with the PV system running, but there is also no taxs specific to have a PV system or taxs by the energy generated. Could you check the example to see if I wrote well these parameters?
An issue that is vital in these calculations and serves much to sell PV systems is the reduction of the grid energy consumption invoice when the PV system it is generating. And this is in direct relationship with the curve of daily consumption of energy versus the values of incident solar radiation. Can we see in SAM yhe daily energy consumption curve or data, that you used? Can we see the relationship between the curve or data of daily energy consumption versus the incident solar radiation?.How does SAM calculate the electricity invoice with the system PV working?
Best Regards.
