Tirur, a city in Kerala, India, offers a promising location for solar energy generation. Situated in the tropics, this area experiences consistent sunlight throughout the year, with seasons characterized more by wet and dry periods than temperature fluctuations.

The solar energy potential in Tirur is impressive, with substantial electricity output across all seasons. Spring stands out as the most productive period, yielding an average of 6.09 kWh per day for each kilowatt of installed solar capacity. Winter follows closely behind with 5.96 kWh/day, while summer and autumn produce 5.12 kWh/day and 4.83 kWh/day, respectively.

Optimal Panel Positioning

For fixed solar panel installations in Tirur, the ideal tilt angle to maximize year-round energy production is 11 degrees facing south. This angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Seasonal Variations

The data reveals that Tirur experiences relatively consistent solar energy potential throughout the year. The spring and winter months offer slightly higher output, making them particularly favorable for solar energy generation. However, the difference between the highest and lowest producing seasons is less than 1.3 kWh/day, indicating a stable year-round potential for solar power.

Environmental Considerations

While Tirur's tropical location is generally advantageous for solar energy, there are some environmental factors to consider:

• Monsoon Season: Kerala experiences heavy rainfall during the monsoon months, typically from June to September. This could potentially reduce solar output due to increased cloud cover.
• Humidity: The region's high humidity levels may lead to increased dust accumulation on solar panels, potentially reducing efficiency.

To mitigate these challenges, several preventative measures can be implemented during solar installation:

1. Use high-quality, weather-resistant solar panels designed to withstand tropical conditions.

2. Install panels at the recommended 11-degree tilt to optimize sunlight exposure and facilitate natural cleaning by rainwater.

3. Implement a regular cleaning schedule, especially during drier periods, to remove dust and maintain panel efficiency.

4. Consider using microinverters or power optimizers to minimize the impact of partial shading during cloudy periods.

In conclusion, Tirur's location offers excellent potential for solar energy generation throughout the year. With proper installation techniques and maintenance practices, the environmental challenges can be effectively managed, making it an ideal site for solar PV systems.

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

Seasonal solar PV output for Latitude: 10.915, Longitude: 75.9202 (Tirur, 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 Tirur, India

To maximize your solar PV system's energy output in Tirur, India (Lat/Long 10.915, 75.9202) 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 Tirur, 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 Tirur, 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
5° North in Summer	16° South in Autumn	26° South in Winter	5° 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 Tirur, 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 Tirur, 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 Tirur, India

The topography around Tirur, India, located at latitude 10.915 and longitude 75.9202, is characterized by a diverse landscape that combines coastal features with inland terrain. Tirur is situated in the Malappuram district of Kerala, a state known for its lush greenery and varied geography. The area surrounding Tirur is predominantly flat to gently undulating, with low-lying coastal plains stretching along the Arabian Sea to the west. As you move inland, the terrain gradually rises, forming small hills and plateaus. The region is crisscrossed by numerous rivers and streams, including the Bharathapuzha River, which flows near Tirur and creates a network of backwaters and estuaries.

Coastal Features

The coastline near Tirur is marked by sandy beaches and occasional rocky outcrops. Mangrove forests and wetlands can be found in some areas, providing important ecological habitats. The flat coastal plains extend for several kilometers inland before giving way to slightly elevated terrain.

Inland Topography

As you move away from the coast, the landscape becomes more varied. Low hills and small plateaus begin to appear, interspersed with fertile valleys and agricultural lands. The soil in this region is generally rich and well-suited for cultivation, supporting a variety of crops including rice, coconut, and various spices.

Potential for Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would be: 1. Inland plains and plateaus: These areas offer relatively flat terrain with good exposure to sunlight throughout the day. The slightly elevated regions to the east of Tirur could be potential candidates. 2. Agricultural lands: Some agricultural areas that are less productive or lying fallow could be repurposed for solar farms. However, this would need to be balanced with food security concerns. 3. Coastal plains: While the immediate coastal areas may be prone to flooding or salt spray, the flat lands slightly inland could be suitable for solar installations. 4. Degraded or barren lands: Any nearby areas that are currently unused due to poor soil quality or lack of vegetation could be ideal for solar PV projects. It's important to note that while the topography around Tirur generally favors solar PV installations, other factors such as land availability, grid connectivity, and environmental considerations would also need to be taken into account when planning large-scale solar projects in this region.
