Solar PV Analysis of Kanpur, India
Kanpur, Uttar Pradesh, India is a pretty good spot for generating solar energy year-round. The amount of electricity you can get from each kilowatt of installed solar panels varies with the season, but it's relatively high throughout the year. In summer and spring, you'll get more than 5 kilowatts per day for each kilowatt of your solar installation. Autumn and winter produce slightly less power per day, but it's still above 3 kilowatts.
The best times to generate solar power in Kanpur are during spring and summer when the sun is out longer and more directly overhead. But even in autumn and winter, there's enough sunlight to make your investment worthwhile.
If you're installing fixed panel solar at this location, tilting them at an angle of 24 degrees facing south will give you the maximum total production over the whole year.
As for local factors that could affect your solar production: Kanpur does experience some air pollution which could potentially reduce the amount of sunlight reaching your panels. Also, dust storms are fairly common in this part of India which can cover up your panels reducing their efficiency.
To mitigate these issues: Regular cleaning maintenance would be necessary to keep dust or other pollutants from blocking sunlight to your panels. You might also consider installing a tracking system that follows the sun across the sky; this could increase output by keeping your panels angled towards the sun all day long - though such systems do add cost and complexity to a project.
Overall though, despite these potential challenges, Kanpur remains an excellent location for harnessing solar energy due its ample sunshine most parts of the year.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
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 Kanpur
Seasonal solar PV output for Latitude: 26.4969, Longitude: 80.3246 (Kanpur, 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 24° South in Kanpur, India
To maximize your solar PV system's energy output in Kanpur, India (Lat/Long 26.4969, 80.3246) throughout the year, you should tilt your panels at an angle of 24° 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 Kanpur, 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 Kanpur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° South in Summer | 32° South in Autumn | 41° South in Winter | 20° 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 Kanpur, 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 Kanpur, 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 Kanpur, India
Kanpur, India is located in the northern plains region of the country. The topography around Kanpur is generally flat and low-lying with an average elevation of about 126 meters above sea level. It lies on the banks of the Ganges River which provides fertile alluvial soil to this region.
The climate in Kanpur is characterized by a tropical savanna climate with dry winters from October to March and hot summers from April to June followed by monsoon rains. The average annual sunshine hours are approximately 2800 - 3000, which indicates a good potential for solar energy generation.
Areas most suited for large-scale solar PV installations would be:
1) Unused or barren lands: These areas are ideal as they do not interfere with agricultural activities or habitation.
2) Rooftops in urban areas: Given that Kanpur is one of the major industrial cities in Uttar Pradesh, there's considerable potential for rooftop solar installations on factories, warehouses, and residential buildings.
3) Areas near existing power infrastructure: This reduces transmission losses and costs associated with connecting to power grids.
4) Regions southwards towards Jhansi and southeast towards Allahabad might also be suitable due to relatively higher levels of sunlight throughout the year.
It's important that any chosen site should have a thorough assessment considering factors such as land availability, proximity to grid connections, local weather patterns (to ensure maximum sunlight exposure), environmental impact assessments etc., before setting up large scale solar PV systems.
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.
