Solar Energy Potential in Claver, Caraga, Philippines
Claver, Caraga, Philippines, situated at latitude 9.5687° North and longitude 125.7326° East, presents a promising location for solar PV installation. Located in the tropics, this region experiences relatively consistent sunlight throughout the year, with seasonal variations primarily defined by wet and dry periods rather than significant temperature fluctuations. Solar energy production at this location shows seasonal variations in electricity output. During summer months, solar panels can generate approximately 6.03 kWh per day for each kilowatt of installed capacity. Spring follows closely with 5.77 kWh/day, while autumn produces about 5.04 kWh/day. Winter months show the lowest production at 4.17 kWh/day per kilowatt installed. For fixed solar panel installations in Claver, Caraga, the ideal tilt angle to maximize year-round energy production is 7 degrees facing South. This carefully calculated angle optimizes solar capture throughout the year, accounting for the location's proximity to the equator and the sun's seasonal positions.Environmental and Weather Considerations
Several significant environmental factors could impact solar production at this location:- Typhoons and heavy rainfall during the wet season (typically June to November) can temporarily reduce solar output and potentially damage poorly secured installations.
- High humidity levels may accelerate corrosion of mounting hardware and electrical connections if not properly protected.
- Dust accumulation during the dry season can gradually reduce panel efficiency.
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 268 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 7° South in Claver, Philippines
To maximize your solar PV system's energy output in Claver, Philippines (Lat/Long 9.5687, 125.7326) 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 Claver, 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 Claver, Philippines. 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 |
|---|---|---|---|
| 6° North in Summer | 15° South in Autumn | 25° South in Winter | 3° 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 Claver, 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 Claver, Philippines.
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 Claver, Philippines
The topography around Claver in Surigao del Norte, Philippines presents a diverse landscape characterized by a striking combination of coastal plains, rolling hills, and mountainous terrain. Situated on the northeastern coast of Mindanao island, Claver features a narrow coastal strip that quickly gives way to increasingly elevated terrain as one moves inland. The municipality is nestled between the Philippine Sea to the east and the gradually rising uplands that eventually form part of the eastern Mindanao mountain ranges to the west. The coastal areas of Claver are relatively flat with some gentle slopes, primarily composed of alluvial deposits and marine sediments. This coastal plain is rather narrow, extending only a few kilometers inland before the elevation begins to increase noticeably. Several rivers and streams originating from the highlands cut through the landscape, creating small valleys and depositing fertile soil as they make their way to the sea.
Inland Topography
Moving inland from the coast, the terrain transitions into undulating hills with moderate slopes. These hills become progressively steeper and more pronounced as they merge with the mountainous backbone that runs through eastern Mindanao. The elevation in these areas can range from approximately 100 meters to over 500 meters above sea level within relatively short distances. The mountainous regions to the west feature more rugged terrain with steeper slopes, deeper valleys, and some plateaus. These highlands are part of the larger mountain system that forms the spine of eastern Mindanao. The vegetation in these areas is typically denser, with substantial forest cover on many of the slopes, though some areas have been cleared for agriculture or mining activities.Solar PV Potential Areas
For large-scale solar photovoltaic development, several areas around Claver show particular promise based on topographical considerations. The most suitable locations would be: The coastal plains and lower foothills offer relatively flat terrain that would minimize site preparation costs. These areas provide good exposure to sunlight with minimal shadowing effects from surrounding topography. The gently sloping terrain in these locations also facilitates easier construction and maintenance access. Some of the elevated plateaus and wider ridgetops in the hilly regions present attractive options for solar development. These locations often have good solar exposure throughout the day and may experience less cloud cover than lower elevations. While requiring more initial site preparation, these areas could potentially capture more consistent solar radiation. Abandoned or reclaimed mining areas within the municipality could be repurposed for solar installations. Claver has a significant mining industry, particularly for nickel, and some previously mined lands offer already-cleared, relatively flat terrain that could be ideal for solar PV development.Topographical Challenges
Despite these promising areas, the topography does present certain challenges for large-scale solar development. The steeper mountain slopes are generally unsuitable due to difficult construction conditions, potential erosion issues, and shadowing effects. The narrow valleys between hills would experience significant shading during parts of the day, reducing their viability. Additionally, the region experiences significant rainfall, which has shaped the topography through erosion, creating drainage channels and uneven terrain in many areas. Proper site selection would need to account for these drainage patterns to avoid flooding and erosion issues for solar installations. The coastal location also means that typhoons occasionally affect the area, so any solar development would need to consider wind exposure based on the local topography, with more sheltered locations potentially offering advantages for infrastructure durability.Philippines solar PV Stats as a country
