Supply and Demand Assessment of Solar PV as O -Grid Option in Asia Pacific Region with Remotely Sensed Data

---

The introduction of solar photovoltaic (PV) systems in isolated areas which are far from
the main grid has provided energy to non-electrified households. Such o-grid technology is very
promising in the Asia Pacific region where increase in population and regional development has
brought an increase in energy demand. This paper presents a methodology to assess the available
supply of energy from solar PV systems and the corresponding demand from non-electrified areas.
Non-electrified high population density areas were extracted using global population distribution
and nightlight data, while the suitability of installing solar PV systems in those areas were identified
based on slope, land cover and estimated solar PV power output. Moreover, the cost and benefits of
installation were estimated based on the levelized cost of electricity generation from PV (LCOEPV)
and the percentage in the total household budget that can shoulder the said expense. Lastly, this
study also proposed a novel and simple method to extract the power transmission lines (TLs) based
on global road network and nightlight data used for defining o-grid areas. Results show that there
are three general types of electrification trend in the region with only 11 out 28 countries exhibiting
the ideal trend of decreasing population living in unlit areas with increasing GDP. This study also
generated maps showing the spatial distribution of high potential areas for solar PV installation in
Cambodia, North Korea and Myanmar as case studies. To date, the high estimated household income
allotted for PV electricity is still experienced in most countries in the region, but these countries
also have high initial generated electricity from PV systems. Outputs from this study can provide
stakeholders with relevant information on the suitable areas for installations in the region and the
expected socio-economic benefits.
