Dombivali, Maharashtra, India, located at 19.2185° N, 73.0741° E, presents a promising location for solar energy generation throughout the year. Situated in the tropics, this area experiences consistent sunlight and is characterized more by wet and dry seasons rather than traditional four-season cycles.

The solar energy potential in Dombivali varies across meteorological seasons, with spring offering the highest output at 7.00 kWh per day for each kilowatt of installed solar capacity. Winter follows with 5.04 kWh/day, then autumn with 4.56 kWh/day, and summer with 4.20 kWh/day. This pattern indicates that solar energy generation is viable year-round, with peak production occurring during the spring months.

For fixed panel installations in Dombivali, Maharashtra, the ideal tilt angle to maximize year-round solar production is 19 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental and Weather Factors

While Dombivali's tropical location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

1. Monsoon season: Heavy rainfall and cloud cover during the monsoon months (typically June to September) may reduce solar output.
2. Air pollution: Being part of the Mumbai Metropolitan Region, Dombivali may experience air pollution, which can decrease solar panel efficiency.

To mitigate these factors, consider the following preventative measures when installing solar panels:

• Use high-quality, weather-resistant panels designed to withstand heavy rainfall and humidity.
• Implement a regular cleaning schedule to remove dust and pollutants from panel surfaces.
• Install panels at the optimal tilt angle to maximize sunlight exposure and promote natural cleaning during rainfall.
• Consider micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.

By addressing these factors, solar installations in Dombivali can maintain high energy production levels throughout the year, taking full advantage of the location's favorable solar conditions.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 422 locations across India. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

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

Seasonal solar PV output for Latitude: 19.2185, Longitude: 73.0741 (Dombivali, 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 19° South in Dombivali, India

To maximize your solar PV system's energy output in Dombivali, India (Lat/Long 19.2185, 73.0741) throughout the year, you should tilt your panels at an angle of 19° 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 Dombivali, 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 Dombivali, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° 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	26° 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 Dombivali, 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 Dombivali, 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 Dombivali, India

The topography around Dombivali, India, is characterized by a mix of urban development and natural features typical of the coastal region of Maharashtra. Situated on the eastern outskirts of Mumbai, Dombivali is part of the larger Mumbai Metropolitan Region. The area is predominantly flat, with gentle undulations and occasional small hills scattered throughout the landscape. To the west of Dombivali lies the Thane Creek, a major water body that separates the mainland from the island city of Mumbai. This coastal influence contributes to the region's generally low-lying terrain. As you move eastward from Dombivali, the land gradually rises, forming part of the Western Ghats' foothills. These areas feature slightly more varied topography, with rolling hills and shallow valleys. The immediate surroundings of Dombivali are largely urbanized, with densely populated residential and industrial areas. However, pockets of open spaces, agricultural land, and small wooded areas can still be found interspersed within the urban fabric, especially towards the outskirts of the city.

Suitable Areas for Large-scale Solar PV

When considering areas nearby Dombivali for large-scale solar PV installations, several factors come into play, including available land, sunlight exposure, and proximity to existing infrastructure. Based on these considerations, the following areas show potential: The eastern outskirts of Dombivali, where the terrain begins to rise slightly, could offer suitable locations for solar farms. These areas generally have more open space and less urban development, providing the necessary land for large-scale installations. The gentle slopes in this region can also be advantageous for optimal solar panel positioning. Areas to the northeast and southeast of Dombivali, such as the regions around Badlapur and Ambernath, might also be suitable. These locations are slightly removed from the densest urban centers and feature a mix of industrial zones and open lands that could potentially be repurposed for solar energy production. The rural areas further east, towards the Western Ghats foothills, could also be considered. While these locations are farther from Dombivali, they offer larger tracts of undeveloped land that could accommodate extensive solar arrays. However, care must be taken to balance energy production needs with environmental conservation efforts in these more pristine areas. It's important to note that any large-scale solar PV project would require detailed site-specific assessments, considering factors such as local zoning laws, environmental impact, and grid connectivity. Additionally, given the rapid urbanization in the Mumbai Metropolitan Region, careful planning would be necessary to ensure that suitable areas are identified and secured for renewable energy development before they are consumed by urban expansion.
