Preventative Measures
To mitigate these potential issues and ensure optimal solar production, consider implementing the following measures:
- Install high-quality, weather-resistant panels capable of withstanding heavy rainfall and humidity.
- Implement a regular cleaning schedule to remove dust and pollutants from panel surfaces.
- Use micro-inverters or power optimizers to minimize the impact of partial shading caused by clouds or pollution.
- Consider a slight increase in panel tilt during monsoon season to promote self-cleaning and improve water runoff.
Overall, Haridwar's location provides a favorable environment for solar PV energy generation throughout the year, with spring and summer offering the highest potential for production. By addressing environmental factors and implementing appropriate preventative measures, solar installations in this area can achieve consistent and efficient energy output.

Solar output per kW of installed solar PV by season in Haridwar
Seasonal solar PV output for Latitude: 29.9478, Longitude: 78.1628 (Haridwar, 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 28° South in Haridwar, India
To maximize your solar PV system's energy output in Haridwar, India (Lat/Long 29.9478, 78.1628) throughout the year, you should tilt your panels at an angle of 28° 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 Haridwar, 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 Haridwar, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 36° South in Autumn | 45° South in Winter | 23° 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 Haridwar, 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 Haridwar, 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 Haridwar, India
Haridwar, located in the northern Indian state of Uttarakhand, sits at the foothills of the Himalayas where the Ganges River emerges from the mountains onto the plains. The topography around Haridwar is characterized by a dramatic transition from mountainous terrain to flat lowlands.
To the north and northeast of Haridwar, the landscape quickly becomes hilly and then mountainous as it rises into the Shivalik Hills, the southernmost and lowest range of the Himalayas. These hills are marked by steep slopes, deep valleys, and dense forests. The elevation in this area increases rapidly, with some nearby peaks reaching heights of over 1,000 meters above sea level.
In contrast, to the south and southwest of Haridwar, the terrain flattens out into the vast Indo-Gangetic Plain. This area is characterized by low-lying, level land with rich alluvial soil deposited by the Ganges and its tributaries over millennia. The elevation here is much lower, typically around 200-300 meters above sea level.
Haridwar itself sits at an elevation of about 314 meters above sea level, positioned at this transition point between the mountains and the plains. The city is surrounded by lush vegetation, including forests and agricultural land, thanks to the abundant water supply from the Ganges and the fertile soil of the region.
Regarding areas suitable for large-scale solar PV installations, the flat terrain of the Indo-Gangetic Plain to the south and southwest of Haridwar would be most appropriate. These areas offer several advantages for solar energy production:
- Flat topography, which simplifies construction and reduces costs associated with land preparation.
- Open spaces with fewer obstructions, allowing for maximum sun exposure throughout the day.
- Proximity to existing infrastructure and population centers, facilitating easier grid connection and power distribution.
- Lower likelihood of land-use conflicts compared to the more ecologically sensitive mountainous regions.
Specific locations within a 50-100 kilometer radius south and southwest of Haridwar, such as areas near cities like Roorkee or Muzaffarnagar, could be particularly suitable. However, it's important to note that any large-scale solar project would need to carefully consider factors such as local land use, environmental impact, and proximity to the electrical grid, in addition to the topographical advantages.
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.

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.
