Design of Solar Electricity (PV) System to Power UBTH, Accident & Emergency Operating Theatre

Abstract

There is a global shift from the conventional power sources based on
fossil fuel to renewable energy resources as a result of the nuisance
of noise, toxic fumes pollution and the global warming of the earth’s
atmosphere resulting in the dreaded climate change. This work
presents the design of solar electricity (photovoltaic) system to power
University of Benin Teaching Hospital (UBTH), Accident and
Emergency operating theatre (A&E). All the electrical appliances
were itemized, their power rating, usage hours and average
energy/load demand for 2 suits of the operating theatre was
determined. The required photovoltaic output power generated from
the photovoltaic active area was calculated. The number of
photovoltaic panels that would provide the PV panel output power to
cater for the load was also calculated. Selection of inverter, battery
banks and cables sizes were carried out. Result shows that average
energy demand for the operating theatre (2 suits) in operation for
twelve (12) hours a day was 147.84 kWh, PV area required was
282.569 m2
. The number of PV panels required was 140. The Total
number of batteries to meet the 12 hours autonomy was ten (10).
Since solar photovoltaic technology has assumed a pride of place
among the renewable energy source being exploited for use and the
ubiquitous nature of sunshine, we recommend solar technology for
residential, commercial, hospitals and isolated communities in the
developing world.
