Modified the methods to download NASA data and Renewable Ninja data as their database changed

Before the effect of the shadows was not considered in the hourly irradiation downloaded from PVGIS or Renewable Ninja. Now it was added.

Added the possiblity to download hourly data of irradiation, wind speed and temperatura from PVGIS, for several years.

Fixed the following bugs, updated EDU version:

• Error downloading irradiation data for several locations from Renewable Ninja.
• Error in calculation of shadows

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
