Solar PV Analysis of Bhilai, India
Bhilai, Chhattisgarh, India is a great location for generating solar energy all year round due to its tropical climate which ensures consistent sunlight for most of the year. The seasons in Bhilai are more characterized by wet and dry periods rather than drastic changes in temperature or daylight hours.
The amount of electricity that can be generated from each kilowatt (kW) of installed solar power varies slightly with each season. In summer, you can expect to generate about 4.81 kilowatt-hours (kWh) per day for each kW of installed solar power. This increases slightly to 4.98 kWh/day in autumn and 4.90 kWh/day in winter, before jumping up significantly to 6.65 kWh/day in spring.
This means that while you can generate a good amount of solar energy throughout the year, spring would be the ideal time as it provides the highest output per kW of installed solar power.
If you're planning on installing fixed panel solar equipment at this location, tilting your panels at an angle of 20 degrees facing south would maximize your total yearly production from your photovoltaic (PV) system.
However, there may be some local factors that could potentially affect your ability to produce solar energy consistently at this location:
1) Monsoon Season: During monsoon season there will likely be less sunshine due to increased cloud cover and rainfall which could decrease the efficiency of your PV system during these months.
2) Dust and Pollution: Bhilai is known for its steel industry which might lead to higher levels of dust and pollution compared other areas; these particles can settle on your panels decreasing their effectiveness by blocking sunlight.
To overcome these challenges you should consider regular cleaning schedules especially during drier seasons when dust accumulation might increase; also consider having a professional service check periodically if any maintenance or repairs are needed after heavy monsoons or storms.
In conclusion, Bhilai's tropical climate and consistent sunlight make it an excellent location for solar energy production all year round, with spring being the most productive season. However, local factors like monsoon season and industrial pollution may require additional maintenance to ensure your solar panels remain efficient.
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 Bhilai
Seasonal solar PV output for Latitude: 21.2129, Longitude: 81.4293 (Bhilai, 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 20° South in Bhilai, India
To maximize your solar PV system's energy output in Bhilai, India (Lat/Long 21.2129, 81.4293) throughout the year, you should tilt your panels at an angle of 20° 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 Bhilai, 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 Bhilai, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° South in Summer | 27° South in Autumn | 36° South in Winter | 15° 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 Bhilai, 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 Bhilai, 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 Bhilai, India
Bhilai, India is located in the central part of the country and is known for its relatively flat terrain. The region has a tropical climate with hot summers and mild winters. The city itself is highly urbanized due to the presence of a large steel plant.
The topography around Bhilai mainly consists of plains with some hilly regions towards the south and east. There are also several rivers flowing through this area, including the Shivnath River.
For large-scale solar PV installations, areas that are most suitable would be those with flat terrain and high levels of sunlight throughout the year. Given this criteria, open plains in Bhilai or slightly outside of it would be ideal locations for such projects.
However, it should be noted that any decision regarding setting up solar PV plants must take into account other factors such as proximity to power grids for transmission purposes, land ownership rights and environmental impact assessments among others.
India solar PV Stats as a country
India ranks 5th in the world for cumulative solar PV capacity, with 49,684 total MW's of solar PV installed. 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.
