Naraingarh, Haryana, India, located in the Northern Sub Tropics, offers a promising location for solar PV energy generation throughout the year. The seasonal variation in electricity output per kW of installed solar indicates a relatively consistent performance, with some fluctuations across different seasons.

Seasonal Solar Performance

Spring emerges as the most productive season, with an impressive output of 6.74 kWh/day per kW installed. Summer follows closely, generating 5.78 kWh/day, while autumn sees a slight decrease to 5.05 kWh/day. Winter experiences the lowest output at 4.22 kWh/day, but still maintains a respectable level of energy production.

Optimal Panel Placement

For fixed panel installations in Naraingarh, Haryana, the ideal tilt angle to maximize year-round solar production is 28 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Environmental Considerations

While Naraingarh generally presents favorable conditions for solar energy production, there are some environmental factors to consider: 1. Monsoon season: The region experiences heavy rainfall during the monsoon months (typically July to September), which can temporarily reduce solar output due to cloud cover. 2. Dust and air pollution: Being in a semi-arid region, dust accumulation on panels can be a concern, potentially reducing efficiency. To mitigate these issues, consider implementing the following measures:

• Install a reliable cleaning system or schedule regular manual cleaning to combat dust accumulation.
• Use high-quality, weather-resistant panels that can withstand heavy rainfall during monsoon season.
• Implement a slight increase in panel tilt during monsoon months to facilitate natural cleaning by rainwater.

Overall, Naraingarh presents a favorable location for solar PV energy generation, with consistent output throughout the year and manageable environmental challenges that can be addressed through proper installation and maintenance practices.

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 Naraingarh

Seasonal solar PV output for Latitude: 30.4805, Longitude: 77.1317 (Naraingarh, 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 28° South in Naraingarh, India

To maximize your solar PV system's energy output in Naraingarh, India (Lat/Long 30.4805, 77.1317) throughout the year, you should tilt your panels at an angle of 28° 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 Naraingarh, 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 Naraingarh, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
14° South in Summer	37° South in Autumn	45° South in Winter	24° 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 Naraingarh, 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 Naraingarh, 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 Naraingarh, India

The area surrounding Naraingarh, India, is characterized by diverse topography that transitions from the plains of Haryana to the foothills of the Himalayas. Located in the northern part of Haryana state, Naraingarh sits at the edge of the Shivalik Hills, which form the southernmost range of the Himalayas. To the south and southwest of Naraingarh, the landscape is primarily flat or gently undulating, consisting of fertile agricultural plains. This area is part of the Indo-Gangetic Plain, known for its rich alluvial soil and extensive farming. As one moves northward and eastward from Naraingarh, the terrain becomes increasingly hilly and rugged, with elevations gradually rising towards the Shivalik range. The region experiences a mix of small hills, valleys, and seasonal streams that flow down from the higher elevations. These features create a varied landscape with some areas of dense vegetation, particularly in the foothills, while other parts remain relatively open and suitable for agriculture or development.

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 ideal locations for solar PV projects would be: The flat or gently sloping areas to the south and southwest of Naraingarh would be highly suitable for large-scale solar PV installations. These regions offer vast open spaces with minimal shading from natural features, allowing for maximum solar exposure throughout the day. The relatively level terrain also simplifies construction and maintenance of solar arrays. Some of the less steep hillsides in the vicinity, particularly those facing south or southwest, could also be potential sites for solar PV projects. These areas may benefit from slightly higher elevations, which can reduce the impact of dust and haze on solar panel efficiency. It's important to note that while the hilly regions to the north and east may receive ample sunlight, the rugged terrain and potential forest cover make them less ideal for large-scale solar installations due to increased construction costs and environmental concerns. Areas near existing power infrastructure and transportation networks would be advantageous for solar PV development, as they would reduce the costs associated with power transmission and equipment transportation. Villages and towns in the plains surrounding Naraingarh might offer such opportunities. When selecting specific sites, developers would need to consider factors such as land availability, proximity to water sources for panel cleaning, and local climate conditions, including the impact of the monsoon season on solar radiation levels.

India solar PV Stats as a country
