Before you purchase WindMapperPro location analysis files for your specific area, you can review our program's features with freely provided WindMapperPro analysis files for 4 radiosonde locations around the world. Below you see the analysis file for Invercargill, New Zealand. Each Analysis will summarize the data which it represents. An Analysis with a longer duration, more soundings, more data points, less ignored data and fewer time gaps would yield more accurate results.
Here are the 'bottom line' numbers for the 3 MW Vestas wind mill shown on the 'Power Curves' tab above. This is a mini-grid scenario with a diesel generator for power during wind lulls and a battery array for power storage during windy periods.
Here again is part of the analysis for Invercargill. The below graph shows the value of getting your wind generator as high as you can at this location. At 1000 feet the capacity factor would more than double what is shown for 344.5 feet. The actual data distributions for each 500 foot altitude are shown in light gray. A detailed explanation of all these screenshots can be found in the help file of the program if you choose to download and install it.
This is a graph that shows you how consistent the winds have been at another site over 14 years. The meaning of the value 'Average % Difference from Average' is that generally, the Capacity factor we expect to see in the future should be in the range of the whole periods' Potential Capacity Factor (15.6% in our case) plus or minus 16% of 15.6.
Below is 'Graph 6' for Invercargill. This Power Output graph is a 30 day window of the kW output of the wind generator along the green line. The area under the line is filled in to show when the batteries were being charged (orange) /discharged (light blue) with battery charging losses in Gray, when the diesel generator was running (red shading below the average use line) and when the wind generator was de-powered due to batteries full (green outline above the average use line). If you add all these values for the whole period, you will end up with the outputs numbers we saw in the analysis above.
Below is the Energy Status graph which shows the whole period wide state of battery charge on the top and the non-wind energy used on the bottom.
Here is a graph which is a radial 'Compass Rose' and it represents information on the most likely wind direction at this location with the longest blue line representing the most likely 'from' direction.
And finally, putting it all together on one screen for easy access, we have the complete interactive analysis screen (1/2 scale):
Another key feature of WindMapperPro allows you to create Studies, which are results of an number of analysis with differing inputs. Studies can be exported to Excel files for further presentations.
A Study was used to create this Excel graph thats shows that the most economic average power to use at this site would be 500 kW.
If you would like WindMapperPro analysis files of your area, install the software and then use the 'Order Data Page', shown below, to create a list of locations of interest to you. This map of the world has about 1000 radiosonde sites shown as black dots. When you move your cursor in this map area, your mouse cursor will be a white circle which you can place over an area of interest and then left drag the circle bigger until the radiosondes of interest are inside the circle. These sites will then fill the left lower list. Click on one site or Ctrl click on multiple sites in the list and then use the '=>' button to transfer them to the 'Order List'. Repeat this procedure until you have all the sites of interest in the Order List. Then, click on 'Request a Quote by e-mail'. This sends the request to us and creates a file which you can email to In a return email, we will send you a quote on having us build these analysis files for you.
