Solar output per kW of installed solar PV by season in Malda

Seasonal solar PV output for Latitude: 24.9998, Longitude: 88.1539 (Malda, 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 23° South in Malda, India

To maximize your solar PV system's energy output in Malda, India (Lat/Long 24.9998, 88.1539) throughout the year, you should tilt your panels at an angle of 23° 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 Malda, 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 Malda, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
9° South in Summer	31° South in Autumn	40° South in Winter	19° 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 Malda, 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 Malda, India.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Malda, India

The topography around Malda, India, located at approximately 25°N and 88°E, is characterized by a predominantly flat landscape with some gentle undulations. This region is part of the vast Indo-Gangetic Plain, which is known for its fertile alluvial soil deposited by the Ganges River and its tributaries over millennia. Malda is situated near the confluence of the Mahananda and Kalindri rivers, which contribute to the area's rich agricultural heritage. The terrain is generally low-lying, with an average elevation of around 31 meters (102 feet) above sea level. As you move away from the immediate vicinity of Malda, the landscape remains relatively flat, with occasional small hills and slight elevations.

Potential for Large-Scale Solar PV

When considering areas nearby Malda for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain in much of the surrounding region is particularly advantageous for solar projects, as it minimizes the need for extensive land preparation and allows for efficient layout of solar panels. The areas to the west and southwest of Malda would likely be most suited for large-scale solar PV installations. These regions tend to have slightly higher elevations and are less prone to flooding compared to the areas closer to the rivers. The higher ground would provide better protection for the solar infrastructure and reduce the risk of water-related damage. Additionally, the rural areas surrounding Malda offer ample open spaces that could potentially be utilized for solar farms. These locations would have the added benefit of being away from urban centers, reducing potential conflicts with existing infrastructure or residential areas. It's important to note that while the topography is favorable, other factors such as land availability, proximity to power grids, and local regulations would also need to be considered when planning large-scale solar PV projects in the region. Furthermore, careful environmental assessments would be necessary to ensure that any solar installations do not negatively impact the area's agricultural productivity or ecological balance.

India solar PV Stats as a country
