Solar output per kW of installed solar PV by season in Ankleshwar
Seasonal solar PV output for Latitude: 21.6362, Longitude: 72.9891 (Ankleshwar, 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 Ankleshwar, India
To maximize your solar PV system's energy output in Ankleshwar, India (Lat/Long 21.6362, 72.9891) 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 Ankleshwar, 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 Ankleshwar, 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 | 28° 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 Ankleshwar, 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 Ankleshwar, 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 Ankleshwar, India
The topography around Ankleshwar, India, is generally characterized by flat to gently rolling terrain. This area is part of the Gujarat alluvial plains, which are formed by sediment deposits from rivers over thousands of years. The landscape is predominantly low-lying, with elevations typically ranging from 10 to 50 meters above sea level.
To the east of Ankleshwar, the terrain gradually rises towards the Satpura Range, but this mountainous region is quite far from the city itself. The immediate surroundings of Ankleshwar are mostly comprised of agricultural lands, interspersed with small villages and industrial areas. The Narmada River flows to the south of the city, creating a fertile river valley that has been extensively cultivated.
For large-scale solar PV installations, the areas most suited would be the open, flat lands surrounding Ankleshwar. These regions offer several advantages for solar energy production:
- The flat terrain makes construction and maintenance of solar panels easier and more cost-effective.
- There are fewer natural obstacles that could cast shadows on the panels, maximizing sunlight exposure.
- The region experiences high levels of solar radiation throughout the year, making it ideal for solar energy production.
Specifically, the rural areas to the north and west of Ankleshwar would be particularly well-suited for large-scale solar PV projects. These areas have vast stretches of open land that are not heavily forested or urbanized. The regions between Ankleshwar and neighboring cities like Bharuch and Surat also offer potential sites for solar farms.
However, it's important to note that some of these areas are currently used for agriculture, so any large-scale solar project would need to carefully consider land use conflicts and potential impacts on local communities and food production. Additionally, proximity to existing electrical infrastructure would be an important factor in selecting the most suitable locations for solar PV 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.
