Solar PV Analysis of Rohtak, India
The location at Rohtak, Haryana, India can be considered pretty good for generating energy through solar photovoltaic (PV) systems year-round. This means that if you install a solar panel system in this area, it will produce a decent amount of electricity throughout the year.
In simpler terms, for every kilowatt (kW) of solar panels installed at this location, you can expect to generate about 5.74 units of electricity per day in summer, 4.53 units in autumn, 3.70 units in winter and as much as 6.68 units per day during spring.
Spring appears to be the most ideal time of the year for generating solar power at this location due to higher daily output levels. However, even during winter which has the lowest daily output levels among all seasons - there’s still a fair amount of energy being produced.
For maximum efficiency from your solar PV system throughout the year at this location, it's recommended that your panels are tilted towards south at an angle of 26 degrees from horizontal level.
As far as environmental or weather factors are concerned that could potentially hamper solar production here; cloudy weather and monsoon rains might reduce sunlight exposure on some days resulting in lower electricity generation by your panels on those days.
However these aren't significant enough issues to deter one from installing a Solar PV system here because over the course of an entire year - sunny days significantly outnumber cloudy or rainy ones here thus ensuring overall healthy production levels.
To ensure greater energy production despite such conditions; regular cleaning and maintenance should be performed so that dust or debris do not accumulate on your panels reducing their efficiency. Also if possible try positioning them somewhere where they won't get shaded by trees or buildings especially during peak sun hours i.e., mid-morning till late afternoon.
During installation process itself - opt for high quality equipment including anti-reflective coated glass panes which can help harness more sunlight even on cloudy days. Plus, using a solar tracker system that automatically adjusts the angle of your panels to follow the sun's path can also help maximize output.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
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 Rohtak
Seasonal solar PV output for Latitude: 28.8964, Longitude: 76.5909 (Rohtak, 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 26° South in Rohtak, India
To maximize your solar PV system's energy output in Rohtak, India (Lat/Long 28.8964, 76.5909) throughout the year, you should tilt your panels at an angle of 26° 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 Rohtak, 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 Rohtak, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° South in Summer | 35° South in Autumn | 43° South in Winter | 22° 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 Rohtak, 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 Rohtak, 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 Rohtak, India
Rohtak, India is located in the northern part of the country and is characterized by a flat terrain. The region falls under the Indo-Gangetic Plain, which is known for its fertile alluvial soil and relatively flat topography with slight undulations.
The climate of Rohtak can be classified as semi-arid to sub-tropical, receiving an average annual rainfall of about 58 cm mostly during the monsoon season from July to September. It experiences high temperatures especially during summers (April to June) where it can reach up to 40 °C or more.
Considering these factors, large-scale solar PV installations could potentially be successful in this region due to abundant sunlight throughout the year. Areas with open fields would be most suitable for such installations since they provide unobstructed exposure to sunlight and easy accessibility for installation and maintenance.
Nearby regions like Jhajjar, Bhiwani, Sonipat which also have similar topographical features may also be suitable for large scale solar PV projects. In fact, there are already several operational solar power plants in Haryana state including those in districts like Sirsa and Faridabad.
However, it's important that any planning for large-scale solar PV considers other factors such as land availability & usage rights; proximity to transmission lines; potential environmental impacts etc., apart from just topography & climate suitability. Detailed feasibility studies would need to be conducted before deciding on specific sites.
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.
