There is a new version 2.5. News: thermoelectric generator (TEG, Seebeck effect), improved hourly and minutes step irradiation.

Fixed an error that occurred with inverters of low power (the unmet load was not considered in some cases).

In addition, when the restrictions were not met, it did not appear in the total NPC cost “INF” but in a very large number. It has been corrected so that the value “INF” appears.

The possibility has also been added that if the renewable installed power in DC is higher than the maximum allowed by the inverter, that combination is discarded.

In addition, the information of unmet restrictions for each combination is shown..

iHOGA can simulate and optimize any case of electricity self-consumption (Net Metering or Net Billing, in annual or monthly periods, including or not rolling credit, etc.).

iHOGA has been updated to avoid an error that occurs when trying to download data from NASA website and it is out of work.

In July the 17th, 2018, we have updated the EDU version of iHOGA. Corrected errors to visualize the column of the nominal capacity in Chinise language (and other non-western languages). Also corrected problem whit wind turbines which output power at 14m/s is 0.

iHOGA has been updated to be able to perform the meteorological data downloads of the new NASA databases

Fixed an error that occurred when downloading NASA data in the event that the computer has a comma “,” as a decimal separation. The corrected EDU version has been updated in the download area.

From April 1, 2018 NASA servers change. With the previous versions of iHOGA you will not be able to download data from NASA. We have updated the EDU version (download area) in order to continue downloading the NASA data.

We have fixed a bug related to stand-alone systems that only include AC generator (diesel or gasoline) and batteries. Also other minor bugs have been fixed. EDU version has been updated.

We have fixed some bugs that affected the management of the batteries in AC grid-connected systems. The EDU version has been updated
