Solar PV Analysis of Ahmedabad, India
Ahmedabad, Gujarat, India, situated at latitude 23.022505 and longitude 72.5713621, is a favorable location for solar power generation due to its sunny climate and substantial average daily energy production per kilowatt of installed solar capacity throughout the year. In this region, the highest energy yield occurs in spring with an average of 7.47 kWh/day per kW of installed solar, followed by summer at 5.50 kWh/day, autumn at 5.06 kWh/day, and winter at 4.94 kWh/day.
To optimize efficiency and harness maximum sunlight exposure in Ahmedabad, Gujarat, it is advisable to tilt fixed solar panels at an angle of 21 degrees towards the South direction. This orientation ensures that the panels receive consistent sunlight throughout the year.
While occasional monsoon rains or hailstorms may occur in this area, they are typically short-lived and infrequent enough not to significantly affect overall solar energy production levels. To further enhance energy output during such weather events, proper maintenance practices like regular cleaning of panels can be employed to ensure optimal performance even under less-than-ideal conditions.
In summary, Ahmedabad's geographical location offers a suitable environment for generating solar power year-round with minimal hindrances from local factors when appropriate installation measures are taken into account.
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 Ahmedabad
Seasonal solar PV output for Latitude: 23.022505, Longitude: 72.5713621 (Ahmedabad, 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 21° South in Ahmedabad, India
To maximize your solar PV system's energy output in Ahmedabad, India (Lat/Long 23.022505, 72.5713621) throughout the year, you should tilt your panels at an angle of 21° 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 Ahmedabad, 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 Ahmedabad, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 29° South in Autumn | 38° South in Winter | 17° 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 Ahmedabad, 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 Ahmedabad, 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 Ahmedabad, India
The topography around Ahmedabad, India is generally flat with some rolling hills to the east and south. The area is mostly agricultural land with a few scattered villages. Areas that would be most suited to large scale solar PV would likely be those that are open and relatively free of obstructions such as trees or buildings. The nearby areas of Sanand, Dholera, and Viramgam could all provide suitable locations for large-scale solar installations.
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.
