Abstract:
With the experience of the global energy crisis
attempts are being made throughout the world to harness
alternate sources of energy. In this respect solar and bio fuel
energy technologies stands out as the potential alternatives.
Though initially photovoltaic technology was restricted to some
special purposes, in recent times with the reduction in price of
PV modules it has expanded to variety of common uses. In
Ethiopia some PV systems have been installed for rural
electrification and for pumping drinking water. Initial
investment for this technology is very high, while operation and
maintenance cost is very low so the reduction in the initial cost
by combining with the bio fuel energy source which have
equivalent energy per gallon and lower pollution emission than
the conventional petroleum fuel is studied. In this paper several
attempts are done to analyze the feasibility of
PV-Diesel-Biodiesel hybrid system in comparison with
PV-Diesel, Diesel-Biodiesel (B20), and Diesel powered systems.
Thus this study provides some guidelines in evaluating the
present situation in the context of economic viability and future
scopes of PV-Diesel-Biodiesel hybrid technology by performing
a case study in Robit Village.
