Sirsa, Haryana, India, located at latitude 29.5386 and longitude 75.0272, presents a promising location for solar energy generation through photovoltaic (PV) systems. This northern sub-tropical region experiences varying levels of solar energy production throughout the year, with some seasons being more favorable than others.

Seasonal Solar Energy Production

The solar energy output in Sirsa fluctuates significantly across the four meteorological seasons. Spring emerges as the most productive period, with an impressive daily output of 6.58 kWh per kW of installed solar capacity. Summer follows closely behind, generating 6.04 kWh per day. Autumn sees a moderate decrease in production, yielding 4.64 kWh daily. Winter experiences the lowest output, with 3.53 kWh per day.

Optimal Times for Solar Generation

Based on these figures, the ideal times for solar energy generation in Sirsa are during spring and summer. These seasons offer longer daylight hours and more direct sunlight, resulting in higher energy production. However, it's worth noting that even during the less productive autumn and winter months, the region still maintains a reasonable level of solar energy generation.

Panel Tilt Angle for Maximum Efficiency

To maximize year-round solar energy production in Sirsa, Haryana, fixed solar panels should be installed at a tilt angle of 26 degrees facing south. This optimal angle has been calculated considering the location's latitude, the Earth's elliptical orbit, and daily solar elevation angles, ensuring the best possible exposure to sunlight throughout the year.

Environmental and Weather Factors

While Sirsa generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

• Dust and air pollution: The region can experience dust storms and high levels of air pollution, which may accumulate on solar panels and reduce their efficiency.
• Extreme temperatures: During summer months, temperatures can soar, potentially affecting the performance of solar panels.

Preventative Measures

To mitigate these challenges and ensure optimal energy production, several preventative measures can be implemented during solar installation:

1. Regular cleaning: Establish a routine cleaning schedule for solar panels to remove dust and pollutants, maintaining their efficiency.

2. Temperature management: Use high-quality panels with good heat dissipation properties and ensure proper ventilation during installation to minimize the impact of extreme temperatures.

3. Robust mounting systems: Install sturdy mounting systems that can withstand occasional dust storms and strong winds.

By addressing these factors and implementing appropriate measures, Sirsa can effectively harness its solar potential and benefit from sustainable energy production throughout the year.

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

Seasonal solar PV output for Latitude: 29.5386, Longitude: 75.0272 (Sirsa, 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 26° South in Sirsa, India

To maximize your solar PV system's energy output in Sirsa, India (Lat/Long 29.5386, 75.0272) throughout the year, you should tilt your panels at an angle of 26° 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 Sirsa, 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 Sirsa, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
13° South in Summer	35° South in Autumn	44° 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 Sirsa, 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 Sirsa, 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 Sirsa, India

The topography around Sirsa, India, located at latitude 29.5386 and longitude 75.0272, is characterized by a predominantly flat landscape typical of the northern Indian plains. This region, situated in the state of Haryana, is part of the larger Indo-Gangetic Plain, which is known for its vast expanses of level terrain. The area surrounding Sirsa consists mainly of agricultural land, with gentle undulations and occasional low-lying areas. The land is generally well-drained, thanks to a network of canals and irrigation systems that have been developed over the years. These flat, open spaces extend for miles in all directions, creating a relatively uniform topographical profile. To the west and southwest of Sirsa, the landscape gradually transitions into the more arid regions of the Thar Desert, which begins in neighboring Rajasthan. However, the immediate vicinity of Sirsa remains predominantly agricultural, with fertile soil supporting various crops.

Suitability for Large-Scale Solar PV

The topography and climate of the Sirsa region make it highly suitable for large-scale solar photovoltaic (PV) installations. Several factors contribute to this suitability: Firstly, the flat terrain around Sirsa provides ideal conditions for solar PV farms. The absence of significant hills or mountains means that there are few natural obstacles to block sunlight, allowing for maximum solar exposure throughout the day. This flat landscape also simplifies the construction and maintenance of solar installations, reducing costs and improving efficiency. Secondly, the region experiences high levels of solar radiation throughout the year, with clear skies for much of the time. The semi-arid climate of Haryana, particularly as one moves towards the western parts of the district, ensures ample sunlight for solar energy generation. The areas most suited for large-scale solar PV installations would be the open, non-agricultural lands to the west and southwest of Sirsa. These areas, which gradually merge with the Thar Desert, offer vast, uninterrupted spaces that could accommodate extensive solar farms without significantly impacting agricultural productivity. Additionally, the regions along the outskirts of Sirsa town, where there is less intensive agriculture, could be potential sites for solar PV projects. These areas would benefit from proximity to existing infrastructure while still providing sufficient space for large installations. It's worth noting that while the entire region around Sirsa is generally favorable for solar energy, careful site selection would be necessary to balance energy production with other land uses, particularly agriculture, which remains a crucial economic activity in the area.
