Kaithal, Haryana, India, located in the Northern Sub Tropics at latitude 29.8015 and longitude 76.4, offers a promising location for solar PV energy generation throughout the year. The seasonal variations in solar energy production provide insights into the potential of this site for solar power installations.
Seasonal Solar Performance
Spring emerges as the most productive season, with an impressive daily output of 6.66 kWh per kW of installed solar capacity. Summer follows closely, generating 5.87 kWh/day, while autumn yields 4.78 kWh/day. Winter, as expected, shows the lowest production at 3.70 kWh/day, but still maintains a respectable output.
The substantial energy production during spring and summer makes these seasons ideal for maximizing solar energy generation. However, the relatively consistent output across all seasons indicates that Kaithal is well-suited for year-round solar energy production, with only a moderate dip during the winter months.
Optimal Panel Installation
For fixed panel installations in Kaithal, Haryana, the ideal tilt angle to maximize year-round production is 27 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 to ensure optimal energy capture throughout the year.
Environmental Considerations
While Kaithal generally presents favorable conditions for solar energy production, there are a few environmental factors to consider:
- Dust and air pollution: Being in a semi-arid region, dust accumulation on panels can reduce efficiency. Regular cleaning and maintenance can mitigate this issue.
- Monsoon season: Heavy rains during the monsoon (typically July to September) may temporarily reduce solar output. Installing panels at the optimal angle helps with natural cleaning during rainfall.
To enhance energy production, consider implementing dust-resistant coatings on panels, establishing a regular cleaning schedule, and ensuring proper drainage systems are in place to handle monsoon rains. Additionally, using high-quality, weather-resistant equipment can help maintain consistent performance across varying weather conditions.
Overall, Kaithal's location offers a favorable environment for solar PV installations, with strong potential for year-round energy generation and only minor challenges that can be effectively managed with proper planning and maintenance.

Ideally tilt fixed solar panels 27° South in Kaithal, India
To maximize your solar PV system's energy output in Kaithal, India (Lat/Long 29.8015, 76.4) throughout the year, you should tilt your panels at an angle of 27° 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 Kaithal, 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 Kaithal, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° 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 | 35° South in Autumn | 45° South in Winter | 23° 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 Kaithal, 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 Kaithal, 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 Kaithal, India
The region surrounding Kaithal, India, located at approximately 29.8015°N latitude and 76.4°E longitude, is characterized by a predominantly flat topography typical of the Indo-Gangetic Plain. This area is part of the state of Haryana, known for its vast agricultural lands and gentle terrain. The landscape around Kaithal is primarily composed of level plains with minimal elevation changes, making it an ideal setting for agriculture and urban development. The topography of the region is largely influenced by its location in the alluvial plains formed by the Indus and Ganges river systems over millions of years. As a result, the soil is generally fertile and well-suited for cultivation. The area experiences a gradual, almost imperceptible slope from north to south, following the natural drainage pattern of the region's rivers and streams. While the immediate vicinity of Kaithal is predominantly flat, there are some subtle variations in the landscape. To the northwest of the city, one might encounter slightly undulating terrain with occasional low-lying areas that may form seasonal wetlands during the monsoon season. To the south and southeast, the flatness becomes even more pronounced, stretching for miles with hardly any noticeable changes in elevation.
Suitability for Large-Scale Solar PV
The topographical characteristics of the region surrounding Kaithai make it highly suitable for large-scale solar photovoltaic (PV) installations. Several factors contribute to this suitability: Firstly, the flat terrain offers an abundance of open spaces that can accommodate extensive solar panel arrays without the need for significant land modification. This reduces installation costs and minimizes environmental impact. Secondly, the lack of major geographical obstacles, such as mountains or dense forests, ensures that there are few natural obstructions to sunlight. This allows for optimal solar exposure throughout the day, maximizing the energy generation potential of solar PV systems. The areas to the south and southeast of Kaithal are particularly well-suited for large-scale solar PV projects. These regions offer vast, uninterrupted stretches of level land that receive ample sunlight. Additionally, the slightly higher elevation compared to the northern parts of the district provides better drainage, reducing the risk of waterlogging during heavy rains. Another advantage of this region is its proximity to existing infrastructure. The flat topography has facilitated the development of road networks and power transmission lines, which are crucial for the construction and operation of large solar farms. This existing infrastructure can help reduce the overall cost of setting up and maintaining solar PV installations. It's worth noting that while the entire area around Kaithal offers favorable conditions for solar energy production, site-specific assessments would be necessary to determine the most optimal locations. Factors such as local land use, soil conditions, and proximity to power substations would need to be considered in addition to the general topographical advantages of the region. In conclusion, the flat, open landscape surrounding Kaithal provides an excellent foundation for the development of large-scale solar PV projects, with the southern and southeastern areas offering particularly promising potential for such initiatives.India solar PV Stats as a country
