Greater Noida, Uttar Pradesh, located in the Northern Sub Tropics of India, offers a promising location for solar PV energy generation throughout the year. The city's geographical position at latitude 28.4927 and longitude 77.5358 provides favorable conditions for harnessing solar power, with varying levels of efficiency across different seasons.
Seasonal Solar Performance
The solar energy output in Greater Noida fluctuates throughout the year, with spring being the most productive season. During spring, solar panels can generate an impressive 6.70 kWh per day for each kilowatt of installed capacity. Summer follows closely, with a daily output of 5.67 kWh/kW. Autumn sees a slight decrease in production, yielding 4.55 kWh/day per kW. Winter experiences the lowest output at 3.66 kWh/day per kW, but still maintains a reasonable level of energy generation.
Optimal Panel Installation
To maximize year-round solar energy production in Greater Noida, Uttar Pradesh, fixed solar panels should be installed at a tilt angle of 25 degrees 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 Greater Noida generally provides favorable conditions for solar energy production, there are some environmental factors to consider. The region experiences a monsoon season, typically from July to September, which can lead to increased cloud cover and potentially reduced solar output. Additionally, air pollution from nearby industrial areas and urban centers may occasionally impact solar panel efficiency.
To mitigate these challenges, several preventative measures can be implemented during solar installation:
- Use high-quality, weather-resistant solar panels that can withstand heavy rainfall and humidity
- Install a robust cleaning system to remove dust and pollutants from panel surfaces regularly
- Implement a slight increase in panel tilt during the monsoon season to facilitate better water runoff and self-cleaning
By addressing these factors, solar installations in Greater Noida can maintain higher energy production levels throughout the year, making it an ideal location for harnessing solar power in India's Northern Sub Tropics.
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.

Solar output per kW of installed solar PV by season in Greater Noida
Seasonal solar PV output for Latitude: 28.4927, Longitude: 77.5358 (Greater Noida, 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 Greater Noida, India
To maximize your solar PV system's energy output in Greater Noida, India (Lat/Long 28.4927, 77.5358) 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 Greater Noida, 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 Greater Noida, 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 |
|---|---|---|---|
| 12° South in Summer | 34° 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 Greater Noida, 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 Greater Noida, 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 Greater Noida, India
The topography around Greater Noida, India, is generally characterized by flat to gently rolling terrain. This area is part of the vast Indo-Gangetic Plain, which is known for its relatively level landscape. The region is primarily composed of alluvial soil deposited by rivers over thousands of years, resulting in fertile land that has been extensively used for agriculture.
Greater Noida itself is situated on a plateau, with an average elevation of about 200 meters (656 feet) above sea level. The surrounding areas have a similar elevation, with only minor variations in height. To the east and northeast of Greater Noida, the terrain gradually slopes towards the Hindon River, while to the west and southwest, it remains mostly flat as it extends towards Delhi.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would have the following characteristics:
- Flat or gently sloping land with minimal shadowing from nearby structures or natural features
- Good solar irradiance throughout the year
- Proximity to existing electrical infrastructure for easy grid connection
- Minimal conflict with agricultural or urban land use
Based on these criteria, some of the most suitable areas for large-scale solar PV installations near Greater Noida would likely include:
1. Open areas to the east and southeast of Greater Noida:
These regions have vast stretches of relatively flat land that are less densely populated and could potentially accommodate large solar farms without significant land use conflicts.
2. Yamuna Expressway Industrial Development Authority (YEIDA) area:
Located to the south of Greater Noida, this region has been earmarked for industrial development and could include designated areas for renewable energy projects, including solar PV installations.
3. Peripheral areas of nearby towns like Dadri and Jewar:
These locations offer a good balance of open space and proximity to existing infrastructure, making them potentially suitable for solar PV projects.
It's important to note that while the topography of the region is generally favorable for solar PV installations, specific site assessments would be necessary to determine the most optimal locations. Factors such as local land use policies, environmental considerations, and grid connectivity would need to be evaluated on a case-by-case basis.
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.
