Graph of hourly avg kWh electricity output per kW of Solar PV installed in Sorsogon, Philippines (by season)

Sorsogon, Bicol Region, Philippines is a good location for year-round solar energy production due to its tropical climate. The sunlight is consistent throughout most of the year and seasons are characterised more by wet and dry periods rather than dramatic temperature changes.

The amount of electricity that can be generated from each kilowatt (kW) of installed solar power varies slightly with the season. In summer, you can expect around 5.79 kilowatt-hours (kWh) per day, in autumn it's about 5.03 kWh/day, in winter it drops to around 4.38 kWh/day, and then rises again in spring to about 6.54 kWh/day.

For best results with a fixed panel installation at this location, the panels should be tilted at an angle of 11 degrees towards the South to maximise total year-round production from solar PV.

However, there may be some local factors that could potentially affect solar production at this location such as heavy rainfall during wet seasons or cloud cover reducing sunlight exposure on certain days which could reduce energy generation capacity temporarily.

To mitigate these potential issues when installing solar panels:
1) Ensure proper drainage so water does not accumulate around your system.
2) Install durable panels designed for harsh weather conditions.
3) Regularly clean your panels to remove any debris or dust that might accumulate over time and block sunlight.
4) Consider using tracking systems that follow the sun's path across the sky for maximum exposure; although they're more expensive than fixed systems they can increase energy output significantly especially during less sunny periods.

In conclusion Sorsogon has high potential for successful photovoltaic installations due to its consistent tropical climate but precautions should still be taken against possible environmental factors like heavy rainfalls or cloudy days which might impede full productivity occasionally yet can also be mitigated effectively with proper planning and maintenance strategies ensuring greater overall energy yield throughout all seasons annually in this region.

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 11° South in Sorsogon, Philippines

To maximize your solar PV system's energy output in Sorsogon, Philippines (Lat/Long 12.9767, 123.9934) 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.

At Latitude: 12.9767, Longitude: 123.9934, the ideal angle to tilt panels is 11° South

Seasonally adjusted solar panel tilt angles for Sorsogon, 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 Sorsogon, Philippines. 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 19° South in Autumn 28° South in Winter 6° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Sorsogon, Philippines as follows: In Summer, set the angle of your panels to 3° facing North. In Autumn, tilt panels to 19° facing South for maximum generation. During Winter, adjust your solar panels to a 28° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 6° angle facing South to capture the most solar energy in Sorsogon, Philippines.

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 Sorsogon, 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 Sorsogon, 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 Sorsogon, Philippines

Sorsogon is located in the Bicol Region of the Philippines, at the southeastern tip of Luzon island. The topography around Sorsogon is relatively diverse, featuring a combination of flatlands, hills, and mountains. It also has coastal areas along the Albay Gulf and Ticao Pass.

The region experiences a tropical climate with abundant sunlight throughout most parts of the year which makes it suitable for solar PV installation. However, considering factors such as land use and availability for large-scale solar installations:

1) Flatland Areas: The flatland areas within Sorsogon City or nearby municipalities like Castilla and Juban could be potential locations for large-scale solar farms due to easier construction and maintenance.

2) Coastal Areas: Some coastal regions may also be suitable if they are not prone to high tides or flooding.

3) Unused Agricultural Lands: Unused or less productive agricultural lands can also serve as good sites since they often have access to infrastructure like roads and power lines which would be necessary for a solar farm.

However, it's important to note that any proposed site should undergo thorough technical feasibility studies including sunlight exposure analysis (solar irradiation levels), grid connectivity options, environmental impact assessment etc., before deciding on its suitability for large-scale solar PV installations.
