estimates for [F.sub.R] ([tau][alpha]) and [F.sub.R][U.sub.L] were used along with SPF test data  to determine the optimal values for each collector.
Database: The solar radiation data for the photovoltaic generator location were downloaded from NASA's data bank, accessed by RETSCREEN
Photovoltaic arrays of various sizes were modeled using RETScreen
to determine the best payback period of the array.
The software (MS Excel and RETScreen
) offer this functionality as a modern tool inserted in their functions.
