Version 1
|
|
|
PVWATTS v. 1 can be used for locations accessible through links on the map below, or
through a text list for U.S. sites; or for sites outside the US, through
text lists by region.
Researchers at the National Renewable Energy Laboratory developed PVWATTS to permit
non-experts to
quickly obtain performance estimates for grid-connected PV systems.
Also available is an option to output hourly performance data. This option can be run after the inital calculation, and outputs the data in a separate browser window. Instructions for saving the output to a text file can be accessed through the "Help" link at the top of the hourly output page. |
