The Army Mobility Equipment Research and Development Center 
(USAi'iWRDC) is presently conducting a one nonth DOD Demonstration 
Study sponsored by ERDA. The objective of this study effort is 
to produce a dez.Qnstration progrm which will define the role of 
Solar Terrestrial Photovoltaic (?/VI syst.e!w as power sources 
for DOD applications. To accomplish this goal, r.umerous potentiai 
demonstrations of DOD applications are beins i2entified and 
analyzed. After the best demonstration projects are selected, 
the  P/U power source requirements and an implesentation plan for 
each dexonstration project will be developed. 
USMERDC has been assigned DOD program management responsi- 
bility for investigation of terrestrial applications of solar 
P/V devices. This assignment inclu6es the study which is the 
subject of this Faper as well as conductins the demonstrations 
evolving from the study. In additioq, USX-lEaDC has been tasked 
to estaDlish a Tri-Service coordinating mechanism relative to 
application of P/V devices and has been fundedrfor'a study to 
idenLify early market potential for P/V devices within DOD. 
In spite of limited experience in Solar P/V devices, USMEF.DC 
is well qualified to Ferforrn the P/V activity outlinec above. 
One of USA!!FtDC's prirrary missions is R&D in Electric Power 
Generation and Distribution. Of particular significance are 
major R&D activities in power conditioning and energy storage. 
Expertise and experience in these technologies will be mcst 
beneficial in establishing requirements for P/V power sources. 
DOD is dedicated to conservation of energy and reduction of 
dependence on hydrocarbon fuel. Tt-. military is also interested 
in determining applications where P,'V offers a tactical advantage. 
There may also be applications which prove cast effective, such 
as remote locations which have a high locistics burden due to 
resupply of fuel. Characteristics of P/V systems which make 
them attractiv$ to the military for electri: power sources inclcde 
high reliability, low maintenance, unattended operatioq, long 
life, silent operation and reduced logistics. 
ERDA is committed to purchase 90 KW of P/V power systems 
which will be supplied to DOD for demonstrations to provid? DOD 
with a basis for future military utilization of P/V devices. 
Two 3 KK systenis will be available on 1 Jansary 1976 for installa- 
tion in the selected der!onstration projects. Two 12 KW systems 
will be provided on 1 April, and the final 60 KW system will be 
supplied in August 1976. 
USWlERDC's study approach is t initially identify multiple 
DOD applications, analyze their F w c , r  syste:? z~~:uirernents 
relative to use of P/t' units, an? recommend t h e  nost promising 
L 3 3  
app1ics:ions to DOD and ERDA for selection of the demonstration 
projects. A preliminary systems analysis will be performed 
and an implementation plan will be developed for each of the 
selected projects.

contacted and there has been \ood response at all levels: 
potential a>plications have been provicied by all the Services. 
Candidate demonstration systems and locations are being analyzed 
using the derived evaluation criteria. Technical -?ata regarding 
available batteries and power conditioning devices are being 
accumlated. The most promising demonstration candidates in 
each of the three power sizes ( 3  KN, 12 KFIJ, and 60 XW) will be 
submitted by 25 July. Following selection of the demonstration 
projects the systems engineering, systems analysis, and 
implementation plan for each project will be initiated. 
The evaluation criteria place emphasis on military market 
potential and military advantages. The military market potential 
is an indicator of both potential energy savings and production 
base potential. The application should benefit from use of a 
P/V power source: Lhere should be an improved mission capability. 
In addition to the above primary considerations,the suitability 
of P/V to integration with the load utilizing available storage 
and power cmditioning equipment is important. Candidates are 
also being evaluate' to determine if there are similar applications 
in the civilian sector and their potential for an impressive 
demonstration which can readily "sell" the advantages of utilizing 
P/V in military applications. 
USAMERDC's projec%ed role in the DOD demonstration prograii 
includes : 
a. Assisting in de\*elopment, fabrication and assembly of 
the Photovoltaic power so.rrce. 
b. Installaticr of the power system at the demonstration 
site and integraticc of it with the load. 
c. Operation and maintenance of each demonstration project. 
d.  Monitoring system performance for at least 12 months to 
determine capability of P/V source f?  provide sufficient power 
to required quality, as dictated by che using equipment. 
e .  Evaluation of the P/V power system's design using 
recorded data: determine if there is adequate or surplus storage 
and/or array, E cc.
