Solar output per kW of installed solar PV by season in Kuppam
Seasonal solar PV output for Latitude: 12.7528, Longitude: 78.3385 (Kuppam, 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 11° South in Kuppam, India
To maximize your solar PV system's energy output in Kuppam, India (Lat/Long 12.7528, 78.3385) throughout the year, you should tilt your panels at an angle of 11° 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 Kuppam, 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 Kuppam, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 3° North in Summer | 17° South in Autumn | 28° South in Winter | 7° 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 Kuppam, 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 Kuppam, 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 Kuppam, India
The area around Kuppam, India, located at 12.7528°N latitude and 78.3385°E longitude, is characterized by a diverse and interesting topography. Kuppam itself is situated in the southern part of Andhra Pradesh state, close to the borders of Tamil Nadu and Karnataka.
The landscape in this region is primarily composed of gently rolling hills and plateaus, interspersed with flat plains. The terrain gradually rises from east to west, with the Western Ghats mountain range visible in the distance to the west. The average elevation of Kuppam is approximately 635 meters (2,083 feet) above sea level, which contributes to its relatively mild climate compared to the hotter lowlands of the region.
The area is dotted with numerous small hillocks and rock formations, typical of the Deccan Plateau. These features create a picturesque landscape with occasional rocky outcrops and boulders. The soil in the region is generally red and sandy, characteristic of the semi-arid climate prevalent in this part of India.
Several seasonal streams and small rivers crisscross the terrain, although they may run dry during the hot summer months. The vegetation is mostly scrub forest and dry deciduous trees, with some areas converted to agricultural use where irrigation is available.
Suitability for Large-scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play:
- The flat or gently sloping plains to the east and southeast of Kuppam would be ideal for solar PV installations. These areas receive ample sunlight throughout the year and have minimal shadowing from hills or other geographical features.
- The slightly elevated plateaus in the region could also be suitable, as they often have good exposure to sunlight and may experience slightly cooler temperatures, which can be beneficial for solar panel efficiency.
- Areas with poor agricultural potential due to the semi-arid climate might be repurposed for solar farms, providing an economic boost to the region without compromising valuable farmland.
- Locations near existing power infrastructure would be advantageous for easier grid connection and power distribution.
It's important to note that while the topography around Kuppam is generally favorable for solar PV installations, specific site assessments would be necessary to determine the most suitable locations. Factors such as local weather patterns, land ownership, environmental impact, and proximity to urban areas would all need to be considered in addition to the topographical features.
