Begusarai, Bihar, India, situated in the Northern Sub Tropics at coordinates 25.4197, 86.1362, presents a generally favorable location for solar PV energy generation throughout the year. The region experiences varying levels of solar potential across different seasons, offering opportunities for consistent energy production.
Seasonal Solar Performance
Solar PV systems in Begusarai demonstrate strong performance across all seasons, with spring being the most productive period. During spring, panels can generate an impressive 6.05 kWh per day for each kilowatt of installed capacity. Summer and autumn also show robust output at 4.80 kWh/day and 4.61 kWh/day, respectively. Winter, while less productive, still maintains a respectable 3.78 kWh/day output.
Optimal Panel Positioning
To maximize year-round solar energy production in Begusarai, 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 location's specific latitude.
Environmental Considerations
While Begusarai's climate is generally conducive to 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 rainfall. This may temporarily reduce solar panel efficiency during these months.
To mitigate the impact of monsoon weather, installers should ensure proper waterproofing and drainage systems for solar installations. Additionally, using high-quality, weather-resistant panels and regular maintenance can help maintain optimal performance even during challenging weather conditions.
Dust and Air Pollution
Begusarai, Bihar, like many parts of Northern India, can experience high levels of dust and air pollution. These particulates can accumulate on solar panels, reducing their efficiency over time. To address this issue, consider implementing the following measures:
- Install automated cleaning systems or schedule regular manual cleaning of panels
- Use anti-soiling coatings on panel surfaces to minimize dust accumulation
By taking these precautions, solar PV systems in Begusarai can maintain high levels of energy production throughout the year, capitalizing on the region's favorable solar conditions.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Begusarai
Seasonal solar PV output for Latitude: 25.4197, Longitude: 86.1362 (Begusarai, 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 Begusarai, India
To maximize your solar PV system's energy output in Begusarai, India (Lat/Long 25.4197, 86.1362) 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 Begusarai, 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 Begusarai, 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 |
|---|---|---|---|
| 9° South in Summer | 31° South in Autumn | 40° South in Winter | 19° 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 Begusarai, 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 Begusarai, 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 Begusarai, India
The topography around Begusarai, India, is characterized by a largely flat and low-lying landscape. This area is part of the Gangetic Plain, a vast and fertile region formed by the Ganges River and its tributaries. The terrain is predominantly composed of alluvial soil, which has been deposited over thousands of years by river systems flowing from the Himalayas.
Begusarai and its surrounding areas have an average elevation of about 40 meters (131 feet) above sea level. The land is generally level, with only slight variations in elevation across the region. This flat topography is interrupted occasionally by small hillocks or elevated areas, but these are not significant enough to drastically alter the overall landscape.
The region experiences a subtropical climate with hot summers and mild winters. It receives moderate rainfall, primarily during the monsoon season. The flat terrain and the presence of rivers and their tributaries make the area prone to seasonal flooding, which can impact land use in some parts.
Areas Suitable for Large-scale Solar PV
For large-scale solar photovoltaic (PV) installations, the areas nearby Begusarai that would be most suited include:
1. Open agricultural lands: The vast stretches of agricultural land in the region, particularly those that are less productive or fallow, could be ideal for solar PV installations. These areas offer large, unobstructed spaces that receive ample sunlight throughout the year.
2. Slightly elevated areas: While not abundant, the slightly elevated areas or small hillocks in the region could be suitable for solar farms. These locations might offer better drainage and reduced risk of flooding compared to the lower-lying areas.
3. Barren or unused government lands: Any barren or unused government lands in the vicinity of Begusarai could be potential sites for solar PV projects. These areas often have fewer competing land-use issues and may be more readily available for large-scale installations.
4. Industrial zones: The outskirts of industrial areas or designated industrial zones near Begusarai could be suitable for solar PV projects. These locations often have the necessary infrastructure and grid connectivity to support large-scale energy projects.
It's important to note that while the flat topography of the region is generally favorable for solar PV installations, careful site selection is crucial to mitigate risks associated with seasonal flooding and to ensure minimal impact on agricultural productivity and local ecosystems.
India solar PV Stats as a country
India ranks 5th in the world for cumulative solar PV capacity, with 49,684 total MW's of solar PV installed.
