Danao, Central Visayas, Philippines, situated at 9.543° N, 123.7726° E, offers a promising location for solar energy generation. This tropical setting benefits from consistent sunlight throughout the year, with seasons primarily characterized by wet and dry periods rather than temperature variations.

Seasonal Solar Performance

Solar panel performance in Danao varies across the meteorological seasons:

• Spring: 6.09 kWh/day per kW installed
• Summer: 5.82 kWh/day per kW installed
• Autumn: 5.13 kWh/day per kW installed
• Winter: 4.63 kWh/day per kW installed

Optimal Panel Placement

For fixed panel installations in Danao, Central Visayas, the ideal tilt angle to maximize year-round solar production is 8 degrees facing South. This angle has been calculated considering daily solar elevation angles, optimal panel tilt, and weighted by daily PV potential using NASA's solar irradiance data.

Environmental Considerations

While Danao's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. Typhoons: The Philippines is prone to tropical cyclones, which can damage solar installations. To mitigate this risk, use sturdy mounting systems and panels rated for high wind speeds. 2. Heavy rainfall: During the wet season, frequent rain can reduce solar efficiency. Installing panels at the optimal angle helps with water runoff and self-cleaning. 3. High humidity: Moisture can potentially affect electrical components. Using corrosion-resistant materials and ensuring proper sealing of electrical connections can prevent issues.

Despite these challenges, with proper planning and installation techniques, Danao remains an excellent location for solar energy production. The consistent sunlight throughout the year, particularly during spring and summer, makes it a viable option for sustainable energy generation.

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 257 locations across Philippines. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 8° South in Danao, Philippines

To maximize your solar PV system's energy output in Danao, Philippines (Lat/Long 9.543, 123.7726) throughout the year, you should tilt your panels at an angle of 8° 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.

At Latitude: 9.543, Longitude: 123.7726, the ideal angle to tilt panels is 8° South

Seasonally adjusted solar panel tilt angles for Danao, Philippines

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 Danao, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° South tilt angle throughout the year.

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 Danao, Philippines

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 Danao, Philippines.

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 Danao, Philippines

The area around Danao, Philippines, located at latitude 9.543 and longitude 123.7726, is characterized by a diverse and varied topography. This region, situated on the eastern coast of Cebu Island, features a mix of coastal plains, rolling hills, and mountainous terrain.

Along the coastline, you'll find relatively flat areas with sandy beaches and some low-lying coastal plains. As you move inland, the landscape gradually transitions into gently rolling hills. These hills become more pronounced and steeper as you progress further west, eventually giving way to the central mountain range that runs through the spine of Cebu Island.

The terrain around Danao is generally rugged, with numerous small valleys and ravines carved out by rivers and streams flowing from the higher elevations towards the coast. The vegetation in this area is typically lush, with a mix of tropical forests, agricultural lands, and grasslands.

When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few factors to consider. The ideal locations would be:

1. The coastal plains and lower hills near Danao: These areas offer relatively flat terrain with good sun exposure throughout the day. They are also closer to existing infrastructure, which could make construction and grid connection easier.
2. Elevated plateaus or ridges in the nearby hills: While potentially more challenging to access, these locations might offer excellent sun exposure and less interference from vegetation or other obstacles.
3. Former agricultural lands or cleared areas in the surrounding region: These spaces could provide large, open areas suitable for solar panel installation without the need for extensive land clearing.

It's important to note that while the topography plays a crucial role in determining suitable locations for solar PV, other factors such as local climate conditions, land ownership, environmental considerations, and proximity to the electrical grid would also need to be carefully evaluated before selecting a site for a large-scale solar installation.
