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

Seasonal solar PV output for Latitude: 19.0911, Longitude: 74.7312 (Ahmednagar, 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 18° South in Ahmednagar, India

To maximize your solar PV system's energy output in Ahmednagar, India (Lat/Long 19.0911, 74.7312) throughout the year, you should tilt your panels at an angle of 18° 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 Ahmednagar, 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 Ahmednagar, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° South in Summer	25° South in Autumn	34° South in Winter	13° 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 Ahmednagar, 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 Ahmednagar, 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 Ahmednagar, India

The landscape surrounding Ahmednagar, India, is characterized by a diverse topography that reflects the region's geological history and climate. Located in the western state of Maharashtra, Ahmednagar sits on the Deccan Plateau, a vast tableland that covers much of central and southern India. The city itself is situated at an elevation of approximately 650 meters (2,130 feet) above sea level. The terrain around Ahmednagar is predominantly flat to gently rolling, with occasional hills and low-lying areas. To the west of the city, the land gradually rises towards the Western Ghats, a mountain range that runs parallel to India's western coast. These mountains create a rain shadow effect, resulting in a semi-arid climate for Ahmednagar and its surroundings. To the east and south of Ahmednagar, the landscape becomes more uniform, with expansive plains stretching for miles. These areas are characterized by sparse vegetation, consisting mainly of drought-resistant shrubs and grasses. The soil in this region is typically thin and rocky, a result of centuries of weathering and erosion. Several rivers and streams crisscross the area, including the Sina River, which flows near Ahmednagar. These water bodies have carved shallow valleys and created fertile strips of land along their banks, contrasting with the drier surrounding areas.

Suitability for Large-Scale Solar PV

When considering areas nearby Ahmednagar for large-scale solar photovoltaic (PV) installations, several factors come into play. The semi-arid climate of the region, with its abundant sunshine and limited cloud cover, makes it an excellent candidate for solar energy production. The flat plains to the east and south of Ahmednagar are particularly well-suited for large-scale solar PV projects. These areas offer vast, unobstructed spaces that receive ample sunlight throughout the year. The lack of significant vegetation or urban development in these regions means that land acquisition and site preparation would be relatively straightforward. Additionally, the gently rolling terrain in some parts of these plains could be advantageous for solar panel placement. Slight slopes facing south or southwest can optimize the angle at which panels receive sunlight, potentially increasing their efficiency. However, it's important to note that the rocky soil and limited water resources in these areas may present challenges for construction and maintenance of solar facilities. Careful planning and sustainable water management practices would be necessary to ensure the long-term viability of any large-scale solar PV project in the region. Areas closer to the Western Ghats, while still receiving significant sunlight, may be less suitable due to increased cloud cover and potential shading from the mountains. Similarly, locations near rivers or in low-lying areas should be avoided due to the risk of flooding and higher humidity levels, which can affect solar panel performance. In conclusion, the vast, open plains to the east and south of Ahmednagar offer the most promising locations for large-scale solar PV installations, combining favorable topography with ideal climate conditions for solar energy production.
