The differences in Significance and Status of 15 factors that might be ofdecisive influence in achieving a large-scale market introduction of
grid-connected photovoltaic (PV) systems are analyzed. As a research method
the opinions of PV experts and persons involved in the implementation of PV
have been surveyed. A questionnaire was sent to about 300 persons all over
the world (America, Europe and Asia). The methods applied to analyze the
returned questionnaires can be divided into a comparing method (Mann-Whitney
test) and ranking methods (Friedman test and the Medal-Classification test).
One of the main conclusion is that the ranking of the main critical success
factors on Significance shows no large differences between the American and
European respondents. The answers from the American and European respondents
show that the technical and financial factors are the most Significant: RD
and D, technical reliability, financing and cost reduction. The Asian ranking
does differ from the American and European ranking. The answers from the
Asian respondents show that the international factors: global developments
and internationalisation together with specialist knowledge and image are the
most Significant success factors. Another main conclusion is that the three
regions differ in the ranking of the actual Status of the factors. A
comparison of the American ranking with the Asian ranking show the largest
differences, whereas Europe is taking an intermediary position. Another
interesting observation is that the Status of factors, e.g.
internationalisation, global developments and the technical/commercial
network, are considered more positive in America, whereas Asia and Europe are
more positive about the factors RD and D, image and financing. More specific
conclusions show that there is a significant difference in answers between
the American and European respondents about the Significance of the factor
cost reduction. There is also a significant difference between the answers
from the Asian respondents versus the American and European answers about the
factor technical reliability. It also occurs that there is a significant
difference about the Status of the factor financing between the American and
European respondents versus the Asian respondents. In addition, all the
respondents have their own idea about the Status of RD and D in their region.
Also, the Status of the factor technical/commercial network is significantly
different for Asia and America. 13 refs.
