regions with lowest irradiation; but also it shows that, although under the base
case conditions the needed investment might not be considered profitable for cer-
tain technologies, the introduction of some incentive mechanism like a capital
subsidy, a tax relief, or a feed-in tariff, would be enough to reverse the situation.
The introduction of such measures at national policy level could make market
conditions favourable for the large-scale deployment of the photovoltaic technol-
ogy in Brazil, making it a viable alternative to contribute significantly to the ex-
pansion of the country's electricity supply capacity.
Further research is recommended into comparisons of “full” life-cycle assess-
ments (including all impact categories that are actually involved) between the
various PV technologies, between PV and other renewables, and between PV and
the electricity mix of targeted receiving countries (in this case Brazil), to allow for
better estimation of the potential benefits of substitution. Besides, there is need to
follow up the assessment in similar terms of the alternatives to PV in the market of
“clean energies”.
