Nepal possesses a vast and largely untapped reservoir of solar energy, with an estimated potential of 210 GW. This figure, which notably dwarfs the country’s recognized hydropower potential of 83 GW, was a key finding in a recent study published in the journal “Energy Sources, Part A: Recovery, Utilization, and Environmental Effects.”
Highlights of the Nepal solar power Study
The comprehensive research was a collaborative effort by experts from Tribhuvan University, Kathmandu University, and the Water and Energy Commission Secretariat. By analyzing satellite data from NASA’s POWER data archive, the team meticulously evaluated the potential for solar power generation across Nepal’s diverse geographical landscape.
According to the study, Nepal receives an average daily solar radiation of 4.42 kWh/m², a promising figure for solar energy development. The potential is not uniform, with the highest levels of irradiation observed in the northern and western regions. Specifically, the Karnali Province in western Nepal shows the greatest promise, while the eastern Terai region has comparatively lower potential.
The research team’s estimate that Nepal could generate up to 210 GW of solar power is a game-changer. This capacity is more than double the country’s hydropower potential and vastly exceeds the target of 25 GW set in the National Renewable Energy Assessment.

Current State of Nepal solar power in Nepal
Despite this immense potential, Nepal’s current energy mix is overwhelmingly dominated by hydropower. Data from the Nepal Electricity Authority reveals that hydropower generates 93.2 percent of the country’s electricity, while solar power contributes a mere 0.33 percent. This heavy reliance on a single, seasonally-variable source has led to persistent power shortages during the dry season when river flows diminish.
The study underscores the critical need for Nepal to diversify its energy sources to bolster energy security. Solar power, with its widespread availability, predictable daily generation cycle, and continually declining costs, stands out as a primary solution to meet the nation’s escalating energy demands and mitigate seasonal deficits.
Barriers to Nepal solar power Expansion
Harnessing Nepal’s solar potential is not without its challenges. The primary obstacles include the high initial investment costs associated with large-scale projects and the absence of a robust, reliable grid system capable of handling intermittent renewable energy. The study suggests that targeted government policies and financial incentives are crucial to surmount these barriers and stimulate the development of solar power projects. Understanding the solar panel manufacturing plant cost breakdown can provide insight into where these initial costs originate.
One of the study’s key recommendations is the strategic integration of solar power with existing hydropower systems. Creating a hybrid hydro-solar grid would allow Nepal to generate consistent power year-round. During sunny, dry months, solar could compensate for reduced hydropower output, creating a more balanced and reliable power supply.
Government Initiatives to Promote Nepal solar power
The Nepalese government has already laid the groundwork for a renewable energy transition through policies like the National Renewable Energy Policy and the Electricity Act. These frameworks are designed to boost the share of renewables in the national grid and curtail dependence on imported fossil fuels.
To meet its ambitious renewable energy targets, Nepal must accelerate investment in solar project development, upgrade its grid infrastructure, and create attractive financial incentives for private investors. The study emphasizes that public-private partnerships will be instrumental in driving this growth. Fostering a domestic industry requires a deep understanding of the basics of solar panel manufacturing and the sophisticated solar panel manufacturing machines involved in production.
Furthermore, the study highlights the significant environmental advantages of solar power. As a zero-emission energy source, solar has a considerably lower environmental footprint than large-scale hydropower projects, which can involve dam construction and ecosystem disruption. By investing in solar, Nepal can significantly reduce its carbon footprint and align with global climate change mitigation efforts.
Future Prospects for Nepal solar power in Nepal
The study concludes with a powerful message: solar power holds the potential to completely transform Nepal’s energy landscape. It offers a sustainable, long-term solution to the country’s energy challenges. With strategic policies, targeted investments, and international collaboration, Nepal can harness its abundant solar resources to not only achieve energy independence but also position itself as a renewable energy leader in the region.
As Nepal navigates the complexities of meeting its energy demands, solar power presents a clear and sustainable path forward. By capitalizing on its vast solar potential, the nation can build a secure and resilient energy future for its growing population and economy.
