Gorakhpur, Uttar Pradesh, India, located in the Northern Sub Tropics at coordinates 26.7631, 83.3729, presents a favorable environment for solar PV energy generation throughout the year. The city experiences varying levels of solar potential across different seasons, offering opportunities for consistent energy production.

Seasonal Solar Performance

Solar energy production in Gorakhpur fluctuates across the four meteorological seasons. Spring stands out as the most productive period, with an impressive daily output of 6.16 kWh per kW of installed solar capacity. Summer and autumn follow closely, yielding 4.57 kWh/day and 4.58 kWh/day, respectively. Winter sees a dip in production, generating 3.43 kWh/day, which is still a respectable amount considering the shorter daylight hours and lower sun angle during this season.

Optimal Panel Installation

To maximize year-round solar energy production in Gorakhpur, Uttar Pradesh, fixed solar panels should be installed at a tilt angle of 25 degrees facing south. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the city's latitude and the Earth's elliptical orbit.

Peak Production Periods

The most ideal time for solar energy generation in Gorakhpur is during the spring months, typically from March to May. This period offers the highest daily output due to clear skies, longer daylight hours, and optimal sun angle. Summer and autumn also provide excellent conditions for solar production, making the period from March to November particularly favorable for solar energy harvesting.

Environmental Factors and Mitigation

While Gorakhpur's climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Monsoon season: The region experiences heavy rainfall during the monsoon months (typically June to September), which can temporarily reduce solar output due to cloud cover and reduced sunlight. 2. Air pollution: Gorakhpur, Uttar Pradesh, like many North Indian cities, can experience high levels of air pollution, particularly during winter months. This can lead to smog and haze, potentially reducing solar panel efficiency. To mitigate these challenges, several preventative measures can be implemented:

• Install high-quality, weather-resistant solar panels that perform well in varying conditions.
• Implement a regular cleaning schedule to remove dust and pollutants from panel surfaces, especially during and after the monsoon season.
• Consider using microinverters or power optimizers to minimize the impact of partial shading on overall system performance.
• Install a monitoring system to track performance and quickly identify any issues affecting energy production.

By addressing these factors and implementing appropriate measures, solar PV installations in Gorakhpur 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 Gorakhpur

Seasonal solar PV output for Latitude: 26.7631, Longitude: 83.3729 (Gorakhpur, 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 25° South in Gorakhpur, India

To maximize your solar PV system's energy output in Gorakhpur, India (Lat/Long 26.7631, 83.3729) throughout the year, you should tilt your panels at an angle of 25° 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 Gorakhpur, 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 Gorakhpur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° 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	32° 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 Gorakhpur, 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 Gorakhpur, 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 Gorakhpur, India

The topography around Gorakhpur, India, is characterized by a relatively flat landscape typical of the Indo-Gangetic Plain. This region is part of the vast alluvial plain formed by the Ganges River and its tributaries over millions of years. The terrain is predominantly level, with only slight variations in elevation across the area.

Gorakhpur itself sits at an elevation of approximately 84 meters (276 feet) above sea level. The surrounding areas maintain a similar elevation, with gentle undulations rather than significant hills or mountains. This flat topography extends for many kilometers in all directions, creating a wide, open landscape.

The region is crisscrossed by several rivers and their tributaries, including the Rapti River, which flows near Gorakhpur. These waterways have shaped the local geography, creating fertile floodplains and occasional low-lying areas prone to flooding during the monsoon season.

Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The flat terrain surrounding Gorakhpur offers numerous advantages for solar energy projects. Ideal locations would include:

1. Open agricultural lands: The vast stretches of farmland in the region could potentially accommodate solar arrays without significant land preparation costs.
2. Fallow or unused lands: Areas that are not actively cultivated or used for other purposes would be prime candidates for solar installations.
3. Areas with good road access: Locations near existing infrastructure would facilitate the construction and maintenance of solar facilities.
4. Regions away from flood-prone zones: While much of the area is flat, it's crucial to avoid low-lying areas near rivers that may be susceptible to flooding.

The districts surrounding Gorakhpur, such as Deoria, Kushinagar, and Maharajganj, likely contain suitable areas for large-scale solar projects. These regions share similar topographical features and have ample open spaces that could be utilized for solar energy generation.

It's important to note that while the flat terrain is advantageous, other factors such as local climate conditions, proximity to power grids, and land availability would also play crucial roles in determining the most suitable locations for large-scale solar PV installations in the vicinity of Gorakhpur.
