| Summary: | A study on the effects of solar flux on the performance of photovoltaic (PV)
energy system in the case of a 100 kWp photovoltaic power generation system has
been done in Marak Parak village, Sabah. Five criteria of solar flux were used to find
out the effects of solar flux to the performance of the PV energy system by applying
the computer analytical method. The overall PV energy system analyses were based
on daily data inputs integrated throughout the year. The results of this research show
that approximately 71.4 percent of the total solar irradiance per year at the PV site is
mostly clear day with some partial clouds cover the sky. Solar flux with a pattern of
sunny in the morning and cloudy in the afternoon is suitable for the photovoltaic
energy system as well. It has contributed 25.3 percent of the total solar irradiance per
year. Solar flux, with a pattern of cloudy in the morning and sunny in the afternoon
has rarely occurred at the PV site as well as the solar flux with a pattern of completely
cloudy day with no direct sun at the PV site, which both contributed only 1.7 percent
and 1.S percent of the total solar irradiance per year respectively. The most
significant effect of the solar flux on the performance of the PV energy system is solar
flux with a pattern of completely cloudy day with no direct sun at the PV site.
Fortunately the occurrence of this kind of solar flux has rarely occurred in four
consecutive days during the whole duration of this research. Therefore the capacity
of the storage batteries can be reduced about 2S.B percent of its initial value to 600
kWh. The PV energy system can maintain its energy supplement to the village of
Marak Parak daily without any problem if the villagers know how to use the energy
efficiently especially at the time of inadequate sunlight to recharge the storage
batteries. The researcher has suggested that the results of this research be used as
a guideline to install a central PV energy system for remote areas or rural villages
with a comprehensive energy development plan from the government |
