Bharatpur, Bagmati Province, Nepal, located in the Northern Sub Tropics, is a pretty good location for generating energy via solar power year-round. The amount of electricity generated from each kilowatt (kW) of installed solar varies by season: 4.63 kWh/day in summer, 4.72 kWh/day in autumn, 4.18 kWh/day in winter and 6.28 kWh/day in spring.
The best time to generate solar energy at this location is during the spring when sunlight is most abundant and can produce up to 6.28 kilowatt-hours (kWh) of electricity per day for every kilowatt of installed solar panels.
For optimal performance throughout the year, fixed panel installations should be tilted at an angle of approximately 26 degrees towards the South as it maximizes exposure to sunlight over different seasons.
However, there could be some local factors that might hinder solar production at this location such as dust or air pollution which could reduce light penetration and therefore decrease efficiency levels; heavy monsoon rains or cloud cover which would limit direct exposure to sunlight; potential damage caused by strong winds or hailstorms; or shading from nearby buildings or trees.
To mitigate these issues when installing solar panels:
1) Regular cleaning can help keep panels free from dust.
2) Installations should ideally be done away from areas prone to heavy cloud cover.
3) Sturdy mounting systems can protect against wind damage.
4) If possible, panels should be placed where they are not shaded by buildings or trees for significant parts of the day.
Remember though that even with these challenges Bharatpur remains a good place for producing electricity using solar power due its high average daily sun hours across all seasons.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 40 locations across Nepal. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Bharatpur
Seasonal solar PV output for Latitude: 27.6798, Longitude: 84.4354 (Bharatpur, Nepal), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 26° South in Bharatpur, Nepal
To maximize your solar PV system's energy output in Bharatpur, Nepal (Lat/Long 27.6798, 84.4354) throughout the year, you should tilt your panels at an angle of 26° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Bharatpur, Nepal
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Bharatpur, Nepal. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° South in Summer | 33° South in Autumn | 43° South in Winter | 22° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Bharatpur, Nepal
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Bharatpur, Nepal.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Bharatpur, Nepal
Bharatpur is located in the Chitwan district of Nepal, which is primarily situated in the flat plains of the Terai region. The city itself lies near the Narayani River and has a relatively flat terrain with fertile soil suitable for agriculture. It experiences a tropical monsoon climate, with hot summers and mild winters.
This type of topography and climate makes Bharatpur potentially suitable for large-scale solar PV installations. The flat plains offer ample space for setting up solar panels without any obstruction to sunlight. Also, being close to the equator, it receives abundant sunlight throughout most parts of the year.
The areas around Bharatpur that could be most suited for large-scale solar PV would likely include:
1) Agricultural lands: These are generally open spaces that receive plenty of sunlight. Dual-use farming can also be considered where crops and solar panels co-exist.
2) Rooftops: Large industrial or commercial buildings in this area may have substantial rooftop space that can accommodate solar panels.
3) Unused land parcels: Any unused or barren land around Bharatpur could also be ideal locations as they wouldn't require clearing forests or disrupting natural habitats.
However, feasibility studies would need to be conducted before deciding on any location considering factors like availability & intensity of sunlight throughout the year, proximity to power grids for easy transmission etc. Additionally, socio-economic aspects like local community acceptance should also be taken into account.
Nepal solar PV Stats as a country
Nepal ranks 89th in the world for cumulative solar PV capacity, with 93 total MW's of solar PV installed. This means that 0.10% of Nepal's total energy as a country comes from solar PV (that's 43rd in the world). Each year Nepal is generating 3 Watts from solar PV per capita (Nepal ranks 86th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Nepal?
Yes, there are incentives for businesses wanting to install solar energy in Nepal. The Government of Nepal has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that install solar systems. Additionally, the government has established a Renewable Energy Fund which provides grants to support research and development activities related to renewable energy technologies.
