Indore, Madhya Pradesh, India is a pretty good place to generate solar energy all year round because it's in the Tropics where there is consistent sunlight throughout most of the year. The amount of electricity you can get from every kilowatt of installed solar power varies slightly with each season. You can expect around 4.74 kilowatt-hours per day in summer, 4.81 in autumn, 4.65 in winter and a high of 7.04 in spring.
Spring is clearly the best time for generating solar energy at this location due to longer daylight hours and more direct sunlight compared to other seasons.
If you're setting up solar panels here, they should be tilted at an angle of 21 degrees facing south for maximum efficiency throughout the year.
As for any potential issues that could affect your solar production, Indore doesn't have many significant ones due to its tropical climate and mostly flat topography which are ideal for solar installations. However, like any other place on earth, it may occasionally experience cloudy or rainy days which could temporarily reduce your system's output.
Also note that during monsoon season (June-September), heavy rainfall might affect production as well so you might want to consider these factors when planning your installation schedule or calculating annual energy output.
To mitigate these issues and ensure greater energy production from your panels:
1) Regular maintenance: Keep them clean and free from dust or bird droppings which can block sunlight.
2) Weatherproofing: Make sure they are properly weatherproofed so that they don't get damaged by heavy rains or strong winds.
3) Backup system: Consider having a backup power source (like batteries or grid connection) for times when the weather isn't ideal.
4) Professional installation: Hire professionals who know how to install the panels correctly with optimum tilt angle and direction according to local conditions.
So overall, Indore offers good conditions for generating electricity via solar power with minor weather-related issues that can be managed with proper planning and installation.
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 Indore
Seasonal solar PV output for Latitude: 22.717, Longitude: 75.8337 (Indore, 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 Indore, India
To maximize your solar PV system's energy output in Indore, India (Lat/Long 22.717, 75.8337) 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 Indore, 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 Indore, 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 |
|---|---|---|---|
| 6° South in Summer | 29° South in Autumn | 38° South in Winter | 16° 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 Indore, 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 Indore, 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 Indore, India
Indore, India is located in the Malwa Plateau region. The topography around Indore is relatively flat with some undulating hills. The city itself is situated on the southern edge of the Malwa Plateau, and it gradually slopes down towards the plains as you move southwards.
The climate in Indore is tropical, receiving abundant sunlight throughout the year making it an excellent location for solar PV installations. Moreover, being a plateau region, there are fewer obstructions like tall buildings or trees to block sunlight.
Large-scale solar PV projects require vast stretches of land that receive ample sunlight throughout the year. In this context, areas to the North and East of Indore like Depalpur and Gautampura could be suitable due to availability of flat lands which receive good amounts of sunlight throughout most parts of the year.
Moreover, other factors such as proximity to transmission lines and substations (for easy integration into grid), access roads (for transportation during installation & maintenance), water availability (for cleaning panels), local regulations regarding land use etc., should also be considered while choosing locations for large-scale solar PV projects.
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.
