This was primarily because of financial limitations at the time it was installed. The clearest sign of the level of satisfaction with the system was the installation of a new and larger array by the Indian Creek Nature Center when the test system was removed. The solar resource has been measured in central Iowa and is sufficient for practical solar energy systems. Currently available solar photovoltaic modules are able to survive for extended periods in the Iowa environment. The solar resource is greatest when energy demand is greatest in central Iowa making it a good fit as a source of peaking power.
Further study is required to evaluate how well solar and wind energy can be made complimentary.
