Oravetz, Steve . 1997. Tips for Maintaining Photovoltaic Systems. 9771 2303. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center.
The Cibola and Tonto National Forests in New Mexico and Arizona have used photovoltaic systems in campgrounds for the past 5 years.
