Solar PV Analysis of Hamirpur, India
In Hamirpur, Himachal Pradesh, India, located at latitude 31.6866 and longitude 76.5218, the generation of solar power is favorable due to its relatively mild and consistent climate throughout the year. The average energy yield per day for each kilowatt of installed solar capacity varies by season: it is approximately 6.12 kWh in Summer, 5.01 kWh in Autumn, 4.12 kWh in Winter, and peaks at around 6.64 kWh during Spring.
The absence of severe weather conditions such as heavy snowfall or high-intensity winds - which are common in other areas within India - further enhances Hamirpur's suitability for photovoltaic (PV) installations as these conditions can negatively impact the efficiency of solar panels.
For optimal energy production from a fixed panel installation at this location, the panels should be tilted at an angle of approximately 29 degrees towards the South. This alignment takes full advantage of the sun's path across the sky to maximize exposure to sunlight throughout all seasons.
However, it is important to note that despite its generally favorable climate for solar power generation, certain local factors could potentially affect productivity levels from PV installations in Hamirpur such as dust accumulation on panels or potential shading due to topographical features like hills or buildings.
To mitigate these potential issues and ensure optimal energy production levels from PV installations here:
1) Regular cleaning schedules should be implemented for dust removal from solar panels since accumulated dust can reduce their efficiency.
2) A careful site assessment should be conducted before installation to avoid any possible shading effects on the panels caused by nearby structures or geographical features.
3) The use of high-quality materials that can withstand potential environmental stressors specific to this region will also contribute significantly towards maintaining peak performance levels over time.
Overall though - considering both seasonal variations and local factors - Hamirpur provides a conducive environment for harnessing renewable energy through solar power systems year-round.
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 Hamirpur
Seasonal solar PV output for Latitude: 31.6866, Longitude: 76.5218 (Hamirpur, 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 29° South in Hamirpur, India
To maximize your solar PV system's energy output in Hamirpur, India (Lat/Long 31.6866, 76.5218) throughout the year, you should tilt your panels at an angle of 29° 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 Hamirpur, 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 Hamirpur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° South in Summer | 38° South in Autumn | 47° South in Winter | 25° 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 Hamirpur, 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 Hamirpur, 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 Hamirpur, India
The topography around Hamirpur, India is mostly flat with some gentle slopes. The nearby areas that would be most suited to large-scale solar PV are the open fields and plains since they can receive maximum sunlight. Additionally, the rooftops of buildings in urban areas could also be used for installing solar panels.
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.
