Muzaffarpur, Bihar, India, located in the Northern Sub Tropics at coordinates 26.1192, 85.3963, offers a promising environment for solar PV energy generation throughout the year. The city experiences varying levels of solar potential across different seasons, providing opportunities for consistent energy production.
Seasonal Solar Performance
Solar energy output in Muzaffarpur fluctuates across the four meteorological seasons. Spring stands out as the most productive period, with an impressive 5.93 kWh/day per kW of installed solar capacity. Summer and autumn follow closely, yielding 4.64 kWh/day and 4.60 kWh/day, respectively. Winter sees a slight dip in production, but still maintains a respectable 3.61 kWh/day.
Optimal Panel Placement
To maximize year-round solar energy production in Muzaffarpur, Bihar, fixed solar panels should be tilted at a 24-degree angle facing south. This optimal angle ensures the panels capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the city's specific latitude.
Environmental Considerations
While Muzaffarpur generally offers favorable conditions for solar energy production, there are some environmental factors to consider. The region experiences a monsoon season, typically from June to September, which can lead to increased cloud cover and potentially reduced solar output. Additionally, the area is prone to dust storms, particularly during the dry season.
To mitigate these challenges, several preventative measures can be implemented:
- Install robust mounting systems capable of withstanding strong winds during monsoons and dust storms
- Use self-cleaning or hydrophobic solar panel coatings to reduce dust accumulation and improve performance during dry periods
- Implement regular cleaning and maintenance schedules to ensure optimal panel efficiency
By addressing these factors, solar installations in Muzaffarpur can maintain high levels of energy production throughout the year, making it an ideal location for harnessing solar power.
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 422 locations across India. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Seasonal solar PV output for Latitude: 26.1192, Longitude: 85.3963 (Muzaffarpur, India), 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 24° South in Muzaffarpur, India
To maximize your solar PV system's energy output in Muzaffarpur, India (Lat/Long 26.1192, 85.3963) throughout the year, you should tilt your panels at an angle of 24° 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 Muzaffarpur, India
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 Muzaffarpur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° South in Summer | 32° South in Autumn | 41° South in Winter | 20° 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 Muzaffarpur, India
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 Muzaffarpur, India.
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 Muzaffarpur, India
The topography around Muzaffarpur, India, located at latitude 26.1192 and longitude 85.3963, is characterized by a predominantly flat landscape. This area is part of the vast Indo-Gangetic Plain, which stretches across northern India. The terrain is generally low-lying and features fertile alluvial soil deposited by the Ganges River and its tributaries over millennia. The region surrounding Muzaffarpur is known for its agricultural productivity, with expansive fields and farmlands dominating the landscape. The flat terrain is punctuated by occasional gentle undulations and small hillocks, but there are no significant elevations or mountains in the immediate vicinity. The area's average elevation is approximately 50 meters (164 feet) above sea level, with minimal variation across the region.
Suitability for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain of the region around Muzaffarpur offers advantages for solar PV development, as it simplifies construction and minimizes shading issues between solar panels. The areas to the south and southwest of Muzaffarpur would likely be the most suitable for large-scale solar PV projects. These regions tend to have slightly higher elevations and are less prone to flooding compared to areas closer to the Ganges River in the north. The elevated ground provides better drainage and reduces the risk of water accumulation, which can be detrimental to solar installations. Additionally, the rural areas surrounding Muzaffarpur, particularly those with less productive agricultural land, could be ideal for solar PV development. These locations often have large, open spaces that can accommodate extensive solar arrays without significant land-use conflicts. It's important to note that while the topography is generally favorable, other factors such as grid connectivity, local climate conditions, and land availability would also need to be considered when selecting specific sites for large-scale solar PV projects in the region.India solar PV Stats as a country
