Solar PV Analysis of Vijayawada, India
Vijayawada, Andhra Pradesh, India, is a great location for solar energy production all year round due to its tropical climate with consistent sunlight throughout most of the year. The amount of electricity generated from each kW of installed solar varies slightly by season. Here's what you can expect:
- In summer, it produces around 4.99kWh/day per kW.
- Autumn sees a slight dip to 4.68kWh/day per kW.
- Winter surprisingly generates more than summer and autumn at 5.15kWh/day per kW.
- Spring has the highest output at 6.68kWh/day per kW.
Therefore, spring would be the most ideal time for solar energy generation in Vijayawada due to the highest rate of electricity production.
For fixed panel installations at this location, tilting panels at an angle of 16 degrees towards South is recommended to maximize total yearly production from solar PV.
However, there might be some local factors that could affect the efficiency of solar panels:
1) Monsoon Season: Vijayawada experiences heavy rainfall during monsoon season which typically lasts from June through September and could reduce sunlight exposure on solar panels thus reducing their efficiency.
2) Dust and Pollution: Dust accumulation on panels can block sunlight and reduce efficiency; pollution in urban areas might also have similar effects.
3) Topographical Features: Any tall buildings or trees nearby could potentially cast shadows over your installation thereby reducing its effectiveness.
To mitigate these issues:
1) Solar Panels should be cleaned regularly especially during dry seasons when dust accumulation is high.
2) During monsoon season when rainfall is high, ensure proper drainage systems are in place so that water doesn't accumulate around your installation damaging it or reducing its lifespan.
3) If possible choose a site for your installation where shadows from nearby structures or trees are least likely to fall on your panels especially during peak sun hours (10 am - 3 pm).
In conclusion, Vijayawada is a very suitable location for solar energy generation with minor considerations to be taken into account for optimal performance.
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 Vijayawada
Seasonal solar PV output for Latitude: 16.5033, Longitude: 80.6465 (Vijayawada, 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 Vijayawada, India
To maximize your solar PV system's energy output in Vijayawada, India (Lat/Long 16.5033, 80.6465) 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 Vijayawada, 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 Vijayawada, 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 |
|---|---|---|---|
| 0° 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 Vijayawada, 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 Vijayawada, 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 Vijayawada, India
Vijayawada is located in the southeastern part of India, in the state of Andhra Pradesh. The city sits on the banks of Krishna River and is surrounded by hills and canals, making up a varied topography that includes both urban areas and agricultural land.
The region has a tropical climate with hot summers and moderate winters, which means it receives ample sunlight throughout most of the year. This makes it potentially suitable for solar photovoltaic (PV) installations.
However, large-scale solar PV installations require vast tracts of relatively flat land to be most effective. In this regard, agricultural lands or barren lands around Vijayawada could be potential sites for such installations. It's important to note that any decision to use agricultural land for solar PV would need to balance food production needs with energy generation goals.
Moreover, regions towards the west and northwest of Vijayawada like Nandigama or Kanchikacherla could also be potential areas for large-scale solar PV given their relatively flatter terrains compared to other surrounding regions.
It must also be noted that detailed feasibility studies considering various factors like local weather patterns, availability & cost of land, proximity to power transmission infrastructure etc., would have to be conducted before deciding on any specific location for setting up a large-scale solar PV plant.
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.
