Agra, Uttar Pradesh, India, situated at latitude 27.1826° N and longitude 78.0256° E, offers a promising location for solar energy generation through photovoltaic (PV) systems. This northern subtropical region experiences varying levels of solar potential throughout the year, with some seasons being more favorable than others.

Seasonal Solar Performance

Solar energy production in Agra fluctuates across the four meteorological seasons. Spring stands out as the most productive period, with an impressive daily output of 6.72 kWh per kW of installed solar capacity. Summer follows with 5.49 kWh/day, while autumn sees a slight decrease to 4.62 kWh/day. Winter experiences the lowest production at 3.62 kWh/day, but still maintains a reasonable output.

Optimal Panel Positioning

To maximize year-round solar energy production in Agra, Uttar Pradesh, fixed solar panels should be tilted at a 24-degree angle facing south. This orientation ensures optimal exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While Agra's climate is generally conducive to solar energy production, there are some environmental factors that could impact efficiency. The region experiences a monsoon season, typically from July to September, which can lead to increased cloud cover and rainfall. This may temporarily reduce solar panel performance during these months.

Additionally, Agra is known for its high levels of air pollution, particularly during the winter months. The accumulation of dust and particulate matter on solar panels can decrease their efficiency. To mitigate this issue, regular cleaning and maintenance of the panels is essential. Installing panels at a slight angle (as recommended) can also help with natural cleaning during rainfall.

Preventative Measures

To ensure optimal energy production in Agra, Uttar Pradesh, consider the following measures:

• Implement a regular cleaning schedule for solar panels, especially during and after the monsoon season and winter months.
• Use anti-soiling coatings on panels to reduce dust accumulation and make cleaning easier.
• Install a monitoring system to track performance and quickly identify any drops in efficiency.
• Consider using bifacial solar panels, which can capture reflected light and potentially increase energy yield in cloudy conditions.

Overall, despite some seasonal variations and environmental challenges, Agra's location provides a favorable setting for solar PV installations, with the potential for significant energy generation throughout the year.

Solar output per kW of installed solar PV by season in Agra

Seasonal solar PV output for Latitude: 27.1826, Longitude: 78.0256 (Agra, 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 Agra, India

To maximize your solar PV system's energy output in Agra, India (Lat/Long 27.1826, 78.0256) 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 Agra, 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 Agra, 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
11° South in Summer	33° South in Autumn	42° South in Winter	21° 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 Agra, 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 Agra, India.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Agra, India

The topography around Agra, India, is characterized by a relatively flat landscape, typical of the Indo-Gangetic Plain. This expansive region is known for its low-lying terrain, with gentle undulations and occasional small hills. The area is primarily composed of alluvial soil deposited by the Yamuna River, which flows through the city. To the north and east of Agra, the land is predominantly level, with vast agricultural fields stretching as far as the eye can see. The Yamuna River meanders through this landscape, creating a fertile floodplain that has been cultivated for centuries. The river's presence has shaped the local topography, forming natural levees and low-lying areas prone to seasonal flooding. To the south and west, the terrain becomes slightly more varied, with occasional rocky outcrops and small hillocks breaking up the otherwise flat landscape. These subtle elevation changes are remnants of the ancient Aravalli mountain range, which has largely eroded over millions of years.

Suitability for Large-Scale Solar PV

When considering areas nearby Agra for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain surrounding the city offers numerous advantages for solar energy development. The most suitable areas for such projects would likely be found to the south and west of Agra, where the following conditions are favorable: First, these regions tend to have slightly higher elevations and fewer obstructions, allowing for maximum sun exposure throughout the day. The gently rolling terrain in these areas can be easily leveled or adapted for solar panel installation without significant earthwork. Second, the land to the south and west is generally less fertile and less intensively cultivated compared to the rich alluvial plains along the Yamuna River. This makes it easier to acquire and repurpose large tracts of land for solar farms without significantly impacting agricultural production. Third, these areas are typically drier and experience less frequent flooding compared to the river valley, reducing the risk of damage to solar infrastructure during monsoon seasons. Lastly, the proximity to Agra's urban center and existing power infrastructure makes it easier to connect large-scale solar projects to the grid, facilitating the distribution of generated electricity to consumers. While specific site selection would require detailed environmental and technical assessments, the regions south and west of Agra present promising opportunities for the development of large-scale solar PV installations, leveraging the area's favorable topography and natural conditions.
