Solar PV Analysis of Karur, India
Karur, Tamil Nadu, India is a good place for producing electricity all year round using solar panels. Its location in the Tropics means it gets plenty of sunlight throughout the year, which is ideal for solar energy production. The amount of electricity you can expect to generate from each kilowatt of installed solar changes slightly with the seasons: you'll get about 5.96kWh/day in Summer, 4.94kWh/day in Autumn, 5.39kWh/day in Winter and 6.84kWh/day in Spring.
The best time to produce solar energy at this location would be during Spring when sunshine hours are longest and intensity is high leading to an output of approximately 6.84 kWh per day per kW installed.
To get the most out of your solar panels all year round here, you should tilt them at an angle that faces 9 degrees South - this will help capture as much sunlight as possible over different times of day and across different seasons.
While Karur's location makes it generally great for generating solar power, there could be local factors that might affect how well your system works like environmental aspects (like dust or air pollution), topography (like hills or buildings that could cast shadows on your panels), weather conditions (like heavy monsoon rains or extreme heat) etc.
If such factors exist they can potentially reduce the amount of sunlight reaching your panels hence reducing their efficiency but there are ways to deal with these issues:
1) Regular cleaning can help if dust or pollution is a problem.
2) If shadows from nearby structures or land forms are blocking sun rays reaching your panel then consider installing them at a higher point if possible.
3) Weather-proofing systems can protect against damage from heavy rains.
4) Cooling mechanisms can prevent overheating during extreme temperatures which otherwise reduces efficiency.
So overall while there may be challenges depending on specific local conditions but they are manageable and Karur remains a good location for 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 Karur
Seasonal solar PV output for Latitude: 10.9536, Longitude: 78.0812 (Karur, 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 9° South in Karur, India
To maximize your solar PV system's energy output in Karur, India (Lat/Long 10.9536, 78.0812) throughout the year, you should tilt your panels at an angle of 9° 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 Karur, 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 Karur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 16° South in Autumn | 26° South in Winter | 5° 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 Karur, 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 Karur, 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 Karur, India
Karur is located in the southern state of Tamil Nadu, India. This region is largely flat with a few small hills scattered around. The landscape consists mainly of agricultural lands and some forested areas. It has a tropical climate with plenty of sunshine throughout the year.
The topography and climate make it suitable for large-scale solar PV installations. The flat agricultural lands could be an ideal location for setting up solar farms without much need for land alteration or deforestation.
However, it's important to note that using agricultural land for solar installations should be carefully considered as it can impact food production and local livelihoods. Therefore, underutilized or barren lands could also be good options.
In terms of nearby areas, Erode district to the north-west and Tiruchirappalli district to the east have similar geographical features and climatic conditions making them potentially suitable for large-scale solar PV projects as well.
Before proceeding with any such project, a detailed feasibility study considering various factors like sunlight availability (solar irradiance), land use policies, environmental impact assessment etc., should be conducted.
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.
