6 FAQs about [Exergy systems Nepal]

How can Nepal improve its energy system?

Nepal should follow its footstep to enhance its energy system by adapting the solar PV system to its energy mix. Enhanced penetration of RETs in Nepal requires an improved financial innovation and an upscaled involvement of private sectors (Palit & Chaurey, 2011 ).

Why should Nepal invest in solar energy?

For this, India has been aggressively investing in solar PV systems with a target of 100 GW of installed solar capacity by 2022, and likewise, China has a similar target within 2020. This is the biggest inspiration for Nepal. Nepal should follow its footstep to enhance its energy system by adapting the solar PV system to its energy mix.

Could India SOLVE Nepal's energy trade-hydro problem?

Nepal's faltering renewables policy may find its solution in energy trade-hydro, RE from India. India and China are energy-hungry nations set to consume half of the world's energy by 2030.

Is Nepal a good place for solar energy?

Nepal has abundant solar energy available throughout the year (Fig. 2 ), with the average solar radiation varying from 3.6 to 6.2 kWh/m 2 /day with 300 days of sunny weather (Awasthi & Poudyal, 2018; World Bank Group, 2017 ). Therefore, it is an ideal place for solar energy.

Is Nepal a grid-connected solar system?

In Nepal, a grid-connected solar system is in its emerging phase. The history of solar power has begun with the 1-MW design at Singha Durbar, 680 kW system at Sundharighat, 100 kW system at Kharipati, 65 kW at Nepal Telecom, a 1 KW test project at the Institute of Engineering, Pulchowk, Campus.

Why does Nepal have a higher per capita electricity consumption?

The higher per capita electricity consumption is assumed to follow the Government's ambition to have an 8.5% economic growth rate, making the country in the list of middle-income countries by 2030 (NRB, 2019). To deliver such a higher economic growth rate, Nepal needs to increase its electricity consumption (Parajuli et al., 2014 ).
