Can solar power power the Nepalese energy system?

Nepal has vast low-cost off-river pumped hydro-energy-storage potential, thus eliminating the need for on-river hydro storage and moderating the need for large-scale batteries. Solar, with support from hydro and battery storage, is likely to be the primary route for renewable electrification and rapid growth of the Nepalese energy system.

Can solar power be installed on rooftops in Nepal?

These panels can be accommodated on rooftops, in conjunction with agriculture and on lakes and unproductive land. Since most existing Nepalese hydro is run-of-river, substantial new storage is required to support a solar-based energy system.

Is solar power a viable alternative source of energy in Nepal?

As an alternative source of energy, solar power is gaining popularity across the global as well as in Nepal. Although the major investments for electricity production has flowed towards hydropower projects in Nepal, investors in solar projects have increased in recent years.

Is solar PV a viable option in Nepal?

Nepal has enormous potential for the deployment of off-river PHES systems, which have a much lower environmental and social impact than river-based hydro storage. The economic advantage of solar PV over fossil and hydro energy in a mature and competitive market is compelling. However, several factors can impede the rapid deployment of solar PV.

How much land does a solar PV system need in Nepal?

It amounts to a few square metres of land per person for the 500-TWh goal, which is much less than the land needed for the associated solar PV systems and very much less than the land alienated by an equivalent river-based system. Nepal has enormous potential for off-river PHES.

Can Nepal achieve energy self-sufficiency?

The deep renewable electrification of energy services including transport, heating and industry will allow solar and wind to largely eliminate fossil fuels over the next few decades. This paper demonstrates that Nepal will be able to achieve energy self-sufficiency during the twenty-first century.
