Solar PV Analysis of Guntur, India
Guntur, Andhra Pradesh, India is a very good location for generating solar energy all year round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. The amount of electricity you can expect to generate from each kilowatt of installed solar power varies slightly by season, but remains relatively high throughout the year.
In summer, you can expect about 4.99 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panels installed. In autumn, this drops slightly to 4.68 kWh/day per kW; in winter it increases to 5.15 kWh/day per kW; and in spring it jumps up significantly to 6.68 kWh/day per kW.
So while you can generate a good amount of electricity from solar power at any time during the year in Guntur, Andhra Pradesh, spring would be an especially productive time due to higher sunlight intensity.
For fixed panel installations at this location, tilting your panels at an angle of 15 degrees South will help maximize your total production from solar PV over the course of a year.
However, there could be some local factors that might affect how much energy you're able to produce with your solar panels in Guntur:
1) Dust and Air Pollution: These are common problems across many parts of India which could potentially reduce the efficiency of your panels by blocking sunlight if not regularly cleaned off.
2) Monsoon Season: Although Guntur gets consistent sunlight throughout most parts of the year, monsoons may cause heavy rainfalls and cloudy skies reducing direct sun exposure on certain days or weeks.
3) Heat: Solar panels actually become less efficient as temperature increases above certain levels so extreme heat could also potentially reduce their performance.
To mitigate these issues:
- Regular cleaning should be done especially during dry seasons when dust accumulation might be higher.
- Installations should be built sturdy enough to withstand heavy rains during monsoon season.
- And installing panels in a way that allows for air circulation behind them can help keep temperatures down and maintain their efficiency.
Overall, Guntur is an excellent location for solar energy production with just a few considerations to bear in mind.
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 Guntur
Seasonal solar PV output for Latitude: 16.3007, Longitude: 80.4639 (Guntur, 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 15° South in Guntur, India
To maximize your solar PV system's energy output in Guntur, India (Lat/Long 16.3007, 80.4639) throughout the year, you should tilt your panels at an angle of 15° 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 Guntur, 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 Guntur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° 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 Guntur, 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 Guntur, 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 Guntur, India
Guntur, India is located in the southeastern part of the country and is characterized by a mix of plains and hilly terrain. The city itself lies on a flat plain, while to the east are low-lying hills. The region experiences tropical climate with hot summers and moderate winters which can be suitable for solar PV installation.
For large-scale solar PV installations, it would be best suited in areas that have flat or gently sloping terrains to maximize sun exposure. In Guntur's case, the plains around the city would be ideal as they offer large tracts of land that could accommodate extensive solar panel arrays. Additionally, these areas are likely to have fewer obstructions such as tall buildings or trees that could potentially block sunlight.
Furthermore, given its location near the coast of Bay of Bengal, Guntur receives abundant sunshine throughout most parts of the year which makes it an ideal candidate for harnessing solar energy.
However, before proceeding with any large-scale project like this one needs to consider factors such as accessibility (for installation and maintenance), proximity to power grids (for easy transmission), local regulations regarding land use and renewable energy projects etc., along with detailed technical feasibility studies including shadow analysis etc.
It's also worth noting that Andhra Pradesh state government where Guntur is located has been promoting renewable energy sources actively in recent years which may provide additional incentives for such initiatives.
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.
