Eluru, Andhra Pradesh, India, situated at 16.7182° N latitude and 81.1041° E longitude, presents a favorable location for solar energy generation throughout the year. Located in the tropics, this region experiences consistent sunlight and is characterized more by wet and dry seasons rather than traditional four-season cycles.

Seasonal Solar Output

The solar energy potential in Eluru varies across meteorological seasons, with spring showing the highest output at 6.76 kWh per day for each kilowatt of installed solar capacity. Winter follows with 5.20 kWh/day, then summer at 5.12 kWh/day, and autumn with the lowest output at 4.57 kWh/day. This pattern indicates that Eluru maintains strong solar potential year-round, with peak production occurring during the spring months.

Optimal Panel Tilt

For fixed solar panel installations in Eluru, Andhra Pradesh, the ideal tilt angle to maximize year-round energy production is 16 degrees facing South. This angle has been calculated considering daily solar elevation angles, optimal panel tilt, and weighted by daily photovoltaic potential using NASA's solar irradiance data.

Environmental Considerations

While Eluru's tropical location offers excellent solar potential, there are some environmental factors to consider:

• Monsoon season: Heavy rainfall during the monsoon months (typically June to September) may reduce solar output due to increased cloud cover.
• Dust accumulation: The region's dry periods can lead to dust buildup on solar panels, potentially decreasing efficiency.

Preventative Measures

To mitigate these factors and ensure optimal energy production, consider implementing the following measures:

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

Overall, Eluru's location proves highly suitable for year-round solar energy generation, with only minor challenges that can be effectively addressed through proper installation and maintenance practices.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

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

Seasonal solar PV output for Latitude: 16.7182, Longitude: 81.1041 (Eluru, 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 16° South in Eluru, India

To maximize your solar PV system's energy output in Eluru, India (Lat/Long 16.7182, 81.1041) throughout the year, you should tilt your panels at an angle of 16° 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 Eluru, 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 Eluru, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	22° South in Autumn	32° South in Winter	10° 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 Eluru, 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 Eluru, 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 Eluru, India

The topography around Eluru, India, is characterized by a predominantly flat landscape with gentle undulations. Located in the West Godavari district of Andhra Pradesh, Eluru sits in the fertile coastal plains of the Krishna-Godavari delta region. The area is known for its rich alluvial soil, which has been deposited over centuries by the nearby rivers. To the east of Eluru, the terrain gradually slopes towards the Bay of Bengal, creating a vast expanse of low-lying coastal plains. These plains are interspersed with numerous irrigation canals, small streams, and agricultural fields, giving the landscape a patchwork appearance. The region's proximity to the coast also means that there are occasional wetlands and marshy areas, particularly as one moves closer to the sea. To the west and northwest of Eluru, the land becomes slightly more elevated, with occasional hillocks and small mounds breaking the otherwise flat horizon. These subtle changes in elevation are barely noticeable to the casual observer but play a role in local drainage patterns and land use.

Potential for Large-scale Solar PV

The areas surrounding Eluru offer several promising locations for large-scale solar photovoltaic (PV) installations. The flat terrain and abundant sunshine in this region make it particularly suitable for solar energy projects. Some of the most favorable areas for such developments include: The expansive agricultural plains to the north and northeast of Eluru present an excellent opportunity for solar PV installations. These areas receive ample sunlight throughout the year and have minimal shadowing issues due to the lack of significant geographical features or tall structures. The slightly elevated regions to the west and northwest of Eluru could also be ideal for solar farms. The gentle slopes in these areas can be advantageous for optimal panel orientation and natural drainage, reducing the risk of water accumulation during monsoon seasons. Unused or fallow lands to the south and southeast of Eluru, particularly those not suitable for agriculture, could be repurposed for solar energy production. These areas often have good road connectivity, which is crucial for the transportation of equipment and maintenance access. It's important to note that while the topography around Eluru is generally favorable for solar PV projects, careful site-specific assessments would be necessary to determine the most suitable locations. Factors such as proximity to power grids, local land use regulations, and environmental considerations would need to be taken into account alongside the topographical advantages when planning large-scale solar installations in this region.
