Solar PV Analysis of Airoli, India
Airoli, Maharashtra, India is a great location for producing solar energy all year round. This is because it's in the Tropics where sunlight is consistent throughout most of the year. The amount of electricity you can expect to produce from each kilowatt (kW) of installed solar varies by season, but stays relatively high all year. You can expect about 4.79 kWh per day in summer, 4.99 kWh per day in autumn, 5.09 kWh per day in winter and a whopping 7 kWh per day in spring.
The best time of year to generate solar at this location would be during spring when the output reaches its peak at 7kWh/day for every kW of installed solar power.
When installing your panels, it's important to tilt them at an angle that will maximize their exposure to sunlight throughout the year - for Airoli, Maharashtra, this angle is about 18 degrees facing South.
However there may be some local factors that could potentially affect your solar production such as monsoon season which brings heavy rain and cloud cover reducing the amount of sunlight reaching your panels; or dust and pollution which could dirty your panels making them less efficient.
To help ensure greater energy production despite these challenges:
1) Install a system that allows you to adjust the angle of your panels so they're more directly facing the sun during different times of year.
2) Regularly clean and maintain your panels especially during dry seasons when dust may accumulate.
3) If possible choose a location away from sources of air pollution like factories or busy roads.
4) Consider investing in battery storage systems so excess energy generated during sunny periods can be stored and used later when sunshine isn't as abundant due to weather conditions like monsoons or cloudy days.
In summary, while there are some potential obstacles related with weather conditions and environmental factors, with proper installation techniques including appropriate panel tilting towards south along with regular maintenance and possible use of battery storage systems, Airoli, Maharashtra, India can be a fantastic location for year-round solar energy production.
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 Airoli
Seasonal solar PV output for Latitude: 19.1518, Longitude: 72.9958 (Airoli, 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 18° South in Airoli, India
To maximize your solar PV system's energy output in Airoli, India (Lat/Long 19.1518, 72.9958) throughout the year, you should tilt your panels at an angle of 18° 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 Airoli, 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 Airoli, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 3° South in Summer | 25° South in Autumn | 34° South in Winter | 13° 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 Airoli, 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 Airoli, 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 Airoli, India
Airoli is a residential and commercial hub located in Navi Mumbai, Maharashtra, India. The topography of Airoli is relatively flat with an average elevation of about 10 meters above sea level. The area around Airoli primarily consists of urban development with some marshy areas due to its proximity to Thane Creek.
The climate in this region is tropical monsoon type, meaning it experiences heavy rainfall during the monsoon season (June-September) but has abundant sunshine for the rest of the year which makes it suitable for solar PV installation.
Considering large-scale solar PV installations, open and flat areas are typically preferred as they allow easy installation and maintenance while maximizing sun exposure. Therefore, non-residential or underdeveloped lands on the outskirts of Airoli could be potential sites for such projects.
Another factor that can influence site selection for large-scale solar projects is proximity to power transmission infrastructure since it reduces costs associated with connecting the project to the grid.
However, before proceeding with any specific location decision, a comprehensive site assessment would be needed considering various factors like land availability and use restrictions, local regulations regarding renewable energy projects etc. Additionally environmental impact assessments may also be required given that this region hosts several protected wetlands which are important bird habitats.
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.
