Solar PV Analysis of Solapur, India
Solapur, Maharashtra, India, located at 17.6735°N, 75.9051°E, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature fluctuations.
Seasonal Solar Performance
The solar energy output in Solapur demonstrates remarkable consistency across seasons, with a notable peak during spring. Here's a breakdown of the expected daily electricity output per kilowatt of installed solar capacity:
- Summer: 5.03 kWh/day
- Autumn: 5.05 kWh/day
- Winter: 5.13 kWh/day
- Spring: 6.79 kWh/day
This data indicates that spring is the most productive season for solar energy generation in Solapur, Maharashtra, with a significant increase in output compared to other seasons. However, the relatively small variations between summer, autumn, and winter suggest that solar panels can operate efficiently year-round.
Optimal Panel Placement
For fixed solar panel installations in Solapur, Maharashtra, the ideal tilt angle to maximize year-round energy production is 17 degrees facing South. This angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data to ensure optimal performance throughout the year.
Environmental Considerations
While Solapur's climate is generally conducive to solar energy production, there are a few environmental factors to consider. The region experiences a hot semi-arid climate, which can lead to dust accumulation on solar panels. Regular cleaning and maintenance of the panels can help mitigate this issue and maintain optimal efficiency.
Additionally, Solapur occasionally experiences monsoon rains, typically between June and September. While these rains can help clean the panels, they may also temporarily reduce solar output due to cloud cover. Installing panels at the recommended angle can help with natural cleaning during rainfall and minimize the impact of temporary shading.
Overall, Solapur's location offers excellent potential for solar energy generation, with consistent output throughout the year and a significant boost during spring months. By addressing minor environmental challenges through proper installation and maintenance, solar PV systems in this area can operate at high efficiency levels year-round.

Solar output per kW of installed solar PV by season in Solapur
Seasonal solar PV output for Latitude: 17.6735, Longitude: 75.9051 (Solapur, 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 17° South in Solapur, India
To maximize your solar PV system's energy output in Solapur, India (Lat/Long 17.6735, 75.9051) throughout the year, you should tilt your panels at an angle of 17° 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 Solapur, 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 Solapur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° 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 | 23° South in Autumn | 33° South in Winter | 11° 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 Solapur, 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 Solapur, 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 Solapur, India
The topography around Solapur, India, is characterized by a relatively flat landscape with some gentle undulations. Solapur is situated in the southeastern part of Maharashtra state, on the Deccan Plateau. This region is known for its generally level terrain, with occasional low hills and shallow valleys.
The area surrounding Solapur is predominantly a semi-arid plain, with sparse vegetation and open spaces. The city itself lies at an elevation of approximately 450 meters (1,480 feet) above sea level. As you move outward from the city center, you'll find a mix of agricultural lands, fallow fields, and patches of scrubland.
To the east and southeast of Solapur, the terrain becomes slightly more varied, with some low-lying hills and rocky outcrops. These features, however, are not significant enough to dramatically alter the overall flat nature of the landscape. The Sina River flows through the region, creating some minor variations in the topography along its course.
Areas Suitable for Large-Scale Solar PV
When considering areas nearby Solapur for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would typically have the following characteristics:
1. Flat or gently sloping land: The areas to the north and west of Solapur tend to be flatter and more open, making them potentially ideal for solar farms. These regions offer vast stretches of level ground that would require minimal land preparation.
2. Low agricultural value: Lands that are less fertile or not actively used for farming would be preferable. Such areas can often be found in the more arid zones surrounding Solapur, particularly to the northwest and southwest.
3. Proximity to infrastructure: Locations closer to existing power transmission lines and roads would be advantageous. The areas along major highways leading out of Solapur, such as the Solapur-Pune Highway to the northwest, could be suitable in this regard.
4. Minimal shadowing: Regions with fewer tall structures or natural features that could cast shadows on solar panels would be ideal. The open plains to the west and southwest of Solapur generally meet this criterion.
5. Adequate solar radiation: While the entire region around Solapur receives good sunlight, areas with slightly higher elevation and clearer skies might be marginally better. Some of the gently elevated areas to the east could potentially offer this advantage.
In conclusion, while much of the land around Solapur could potentially support solar PV installations, the most promising areas appear to be the open, flat lands to the north, west, and southwest of the city. These regions combine the necessary topographical features with the practical considerations required for large-scale solar energy projects.

Are there incentives for businesses to install solar in India?
Yes, there are several incentives for businesses wanting to install solar energy in India. These include:
1. Capital Subsidy: The Ministry of New and Renewable Energy (MNRE) provides a capital subsidy of up to 30% on the cost of installing solar power systems for commercial and industrial establishments.
2. Accelerated Depreciation: Businesses can avail accelerated depreciation benefits under Section 32 of the Income Tax Act, 1961, which allows them to claim tax deductions on investments made in solar projects over a period of five years instead of claiming it all at once.
3. Net Metering: This policy allows businesses to sell excess electricity generated from their rooftop solar system back into the grid at retail rates, thus reducing their electricity bills significantly.
4. Solar Renewable Energy Certificates (SREC): Businesses can earn SRECs by generating renewable energy through their rooftop solar systems and then selling these certificates in the open market or trading platforms like IEX or PXIL at predetermined prices set by state regulatory commissions.
