Khandagiri, located in Odisha, India, presents a favorable environment for solar energy generation throughout the year. This tropical location, with its consistent sunlight patterns, offers promising potential for solar PV installations.
Seasonal Solar Performance
The solar energy output in Khandagiri varies across seasons, with spring being the most productive period. During spring, solar panels can generate an impressive 6.17 kWh per day for each kilowatt of installed capacity. Summer follows with 4.78 kWh/day, while winter and autumn produce 4.50 kWh/day and 4.44 kWh/day, respectively.
This seasonal variation indicates that Khandagiri experiences optimal solar conditions during spring, making it an excellent time for maximum energy production. However, the relatively consistent output across other seasons suggests that solar PV systems can operate efficiently year-round.
Optimal Panel Placement
For fixed solar panel installations in Khandagiri, the ideal tilt angle to maximize year-round production is 19 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.
Environmental Considerations
While Khandagiri offers favorable conditions for solar energy production, there are some environmental factors to consider:
- Monsoon season: Heavy rainfall and cloud cover during the monsoon months (typically June to September) may reduce solar efficiency.
- Dust and pollution: Being in a tropical region, dust accumulation on panels can be a concern, potentially affecting energy output.
To mitigate these factors, consider implementing the following measures:
- Install a reliable cleaning system or schedule regular panel cleaning to combat dust accumulation.
- Use high-quality, weather-resistant panels that can withstand heavy rainfall and humidity.
- Implement a slight increase in panel tilt during monsoon season to facilitate natural cleaning by rainwater.
By addressing these environmental factors, solar PV installations in Khandagiri can maintain optimal performance and ensure consistent energy production throughout the year.
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 Khandagiri
Seasonal solar PV output for Latitude: 20.2634, Longitude: 85.7885 (Khandagiri, 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 Khandagiri, India
To maximize your solar PV system's energy output in Khandagiri, India (Lat/Long 20.2634, 85.7885) 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 Khandagiri, 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 Khandagiri, 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 |
|---|---|---|---|
| 4° South in Summer | 26° South in Autumn | 35° South in Winter | 14° 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 Khandagiri, 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 Khandagiri, 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 Khandagiri, India
The topography around Khandagiri, India, located at latitude 20.2634 and longitude 85.7885, is characterized by a mix of gently rolling hills and flat plains. This area, situated in the eastern state of Odisha, features a landscape that transitions from the coastal plains in the east to the more elevated Eastern Ghats mountain range in the west. In the immediate vicinity of Khandagiri, the terrain is relatively flat with occasional low-lying hills. The famous Khandagiri and Udayagiri caves are carved into two adjacent hills, which rise abruptly from the surrounding plain. These hills are part of a series of rocky outcrops that punctuate the otherwise level landscape. As one moves away from Khandagiri, the topography becomes more varied. To the west, the land gradually becomes more undulating, with an increasing number of hills and small valleys. This area marks the beginning of the Eastern Ghats, a discontinuous chain of low mountains and hills that runs parallel to the east coast of India.
Suitable Areas for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine flat or gently sloping terrain, ample sunlight, and minimal shading from natural or man-made structures. The plains to the east and southeast of Khandagiri offer promising potential for solar PV development. These areas feature expansive, open spaces with relatively flat terrain, which is ideal for the installation of large solar arrays. The lack of significant geographical features in this direction means there are fewer obstacles to block sunlight, maximizing the potential energy generation. Another suitable area lies to the north and northeast of Khandagiri, where the landscape remains predominantly flat. This region, extending towards the city of Bhubaneswar, includes agricultural lands and open areas that could be repurposed for solar energy production. While the hilly regions to the west might seem less ideal due to their uneven terrain, some of the plateaus and wider valleys between the hills could also be considered for solar PV installations. These areas would require more careful planning and potentially more expensive site preparation, but they could still be viable options, especially if they receive consistent sunlight throughout the day. It's important to note that while topography is a crucial factor in determining suitable locations for solar PV, other considerations such as proximity to power grids, land availability, and local regulations would also play significant roles in the final selection of sites for large-scale solar energy projects in the region around Khandagiri.India solar PV Stats as a country

This means that 6.50% of India's total energy as a country comes from solar PV (that's 11th in the world). Each year India is generating 36 Watts from solar PV per capita (India ranks 56th in the world for solar PV Watts generated per capita). [source]
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.
