Badalgama Ihala, North Western Province, Sri Lanka, located at 7.3015° N, 79.9848° E, presents a favorable environment for solar PV energy generation throughout the year. This tropical location experiences consistent sunlight and is characterized more by wet and dry seasons than traditional four-season cycles.

The solar energy potential in Badalgama Ihala remains relatively stable across all meteorological seasons. Spring sees the highest output at 6.58 kWh/day per kW installed, followed closely by summer at 6.32 kWh/day. Winter maintains a strong performance at 6.21 kWh/day, while autumn experiences a slight dip to 5.65 kWh/day.

For fixed panel installations in this location, the ideal tilt angle to maximize year-round solar production is 7 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's proximity to the equator.

Optimal Times for Solar Generation

The most productive periods for solar energy generation in Badalgama Ihala are during the dry seasons, typically from December to March and July to August. These months often experience clearer skies and more intense sunlight, boosting solar panel efficiency.

Environmental and Weather Considerations

While the location is generally favorable for solar production, there are some factors to consider:

1. Monsoon seasons: The southwest monsoon (May to September) and northeast monsoon (December to February) can bring heavy rainfall and cloud cover, potentially reducing solar output.
2. High humidity: The tropical climate's high humidity levels may lead to accelerated wear on solar equipment if not properly protected.

To mitigate these challenges, consider implementing the following measures when installing solar systems:

• Use corrosion-resistant materials and weatherproof enclosures for all electrical components.
• Install a robust drainage system to prevent water accumulation on panels.
• Implement regular cleaning schedules to remove dust and debris, which can accumulate more quickly in humid environments.
• Consider micro-inverter or power optimizer systems to minimize the impact of partial shading during cloudy periods.

By addressing these factors, solar installations in Badalgama Ihala can maximize their energy production potential and maintain long-term efficiency in this tropical climate.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 109 locations across Sri Lanka. 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 Badalgama Ihala

Seasonal solar PV output for Latitude: 7.3015, Longitude: 79.9848 (Badalgama Ihala, Sri Lanka), 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 7° South in Badalgama Ihala, Sri Lanka

To maximize your solar PV system's energy output in Badalgama Ihala, Sri Lanka (Lat/Long 7.3015, 79.9848) throughout the year, you should tilt your panels at an angle of 7° 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 Badalgama Ihala, Sri Lanka

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 Badalgama Ihala, Sri Lanka. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
9° North in Summer	13° South in Autumn	23° South in Winter	1° 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 Badalgama Ihala, Sri Lanka

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 Badalgama Ihala, Sri Lanka.

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 Badalgama Ihala, Sri Lanka

The topography around Badalgama Ihala, Sri Lanka, is characterized by a mix of gently rolling hills and flat lowlands. This area is situated in the western part of the country, not far from the coast. The landscape is primarily composed of lush tropical vegetation, including dense forests and agricultural lands. The terrain gradually rises from the coastal plains towards the interior, creating a subtle elevation change as one moves eastward from Badalgama Ihala. Rivers and streams crisscross the region, contributing to its overall fertility and supporting the local agriculture. The Maha Oya, a significant river in the area, flows nearby, influencing the local topography and creating small valleys and floodplains along its course. These water bodies have shaped the land over time, carving gentle contours into the otherwise relatively flat terrain.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat, open areas with minimal shading from trees or hills. These conditions are crucial for maximizing sunlight exposure and efficiency of solar panels. The lowland areas surrounding Badalgama Ihala offer promising potential for solar PV development. These flat expanses, particularly those currently used for agriculture or cleared land, could be repurposed for solar farms. The gentle slopes in some areas might even be advantageous, as they could be oriented to optimize solar panel placement for maximum sun exposure throughout the day. Areas to the east of Badalgama Ihala, where the terrain begins to rise slightly, might also be suitable. These elevated locations could benefit from reduced humidity and potentially clearer skies, factors that can enhance solar energy production. However, care must be taken to avoid areas with dense forest cover or steep inclines, as these would require extensive clearing or grading, which could be environmentally and economically costly. It's important to note that while the topography is favorable in many nearby areas, other factors such as proximity to power infrastructure, land ownership, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar PV projects. A comprehensive site assessment would be necessary to identify the optimal areas for such developments in the vicinity of Badalgama Ihala.
