Solar output per kW of installed solar PV by season in North Lakhimpur
Seasonal solar PV output for Latitude: 27.2413, Longitude: 94.1034 (North Lakhimpur, 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 27° South in North Lakhimpur, India
To maximize your solar PV system's energy output in North Lakhimpur, India (Lat/Long 27.2413, 94.1034) throughout the year, you should tilt your panels at an angle of 27° 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 North Lakhimpur, 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 North Lakhimpur, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° South in Summer | 33° South in Autumn | 43° South in Winter | 21° 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 North Lakhimpur, 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 North Lakhimpur, 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 North Lakhimpur, India
The topography around North Lakhimpur, India, is characterized by a diverse landscape that transitions from the flat plains of the Brahmaputra Valley to the foothills of the Eastern Himalayas. North Lakhimpur itself is situated in the northeastern part of Assam, near the border with Arunachal Pradesh.
The immediate area surrounding North Lakhimpur is primarily flat to gently rolling terrain, typical of the Brahmaputra Valley. This region is known for its fertile alluvial soil, which supports extensive agriculture. As you move north and northeast from the town, the landscape gradually becomes more undulating, with low hills and small valleys appearing.
Further north, the terrain becomes increasingly hilly as it transitions into the foothills of the Eastern Himalayas. These areas are characterized by steeper slopes, deeper valleys, and denser vegetation. Several rivers and streams originating from the Himalayan range flow through this region, creating a network of waterways that shape the local topography.
Regarding areas suitable for large-scale solar PV installations, the flat plains south and southwest of North Lakhimpur would be the most promising. These areas offer several advantages for solar energy development:
- Ample open space with minimal obstructions to sunlight
- Relatively level ground, reducing the need for extensive land preparation
- Easier access for construction and maintenance
- Proximity to existing infrastructure and power grids
The agricultural lands in the Brahmaputra Valley, particularly those that are less productive or prone to flooding, could be considered for solar PV projects. However, it's important to balance energy development with food security concerns.
The hilly areas to the north and northeast, while potentially having good solar exposure on south-facing slopes, would generally be less suitable for large-scale installations due to the challenging terrain, increased construction costs, and potential environmental impacts.
It's worth noting that any solar PV development in this region would need to consider factors such as seasonal flooding, potential seismic activity, and local weather patterns, including the impact of the monsoon season on solar energy generation.
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.
