The Bicol Region in the Philippines, located within the tropics, is a suitable location for solar energy production throughout the year. This is due to its consistent sunlight exposure and distinct wet and dry seasons. The amount of electricity that can be generated from each kilowatt of installed solar power varies by season: 5.60 kWh/day in summer, 4.74 kWh/day in autumn, 4.08 kWh/day in winter, and 6.25 kWh/day in spring.

This means that spring and summer are the best times for generating solar power at this location because these seasons have longer daylight hours resulting in higher energy output per day from your solar panels.

For maximum efficiency year-round at this location, it's recommended to install fixed panel installations tilted at an angle of 11 degrees facing southward.

However, there could be some local factors that may affect the overall performance of your solar panels here:

1) Weather conditions: The region experiences typhoons frequently which could damage or obstruct your panels with debris; hence it's important to secure them properly against strong winds and regularly clear any obstructions on their surface.

2) High humidity levels: In tropical climates like Bicol Region where high humidity is common, dust particles stick more easily onto surfaces which might lower your panels' efficiency over time if not cleaned regularly.

To mitigate these issues:
- Install sturdy mounting systems for your panels to withstand strong winds during typhoon season.
- Regular cleaning/maintenance should also be scheduled to ensure efficient operation since dust accumulation can reduce output significantly.
- If possible consider installing adjustable tilt mounts so you can adjust panel angles depending on seasonal variations or weather conditions.

In conclusion - while there are challenges associated with producing solar energy here due to local environmental factors such as frequent storms and high humidity levels - they can largely be mitigated through proper installation methods (like using sturdy mountings), regular maintenance/cleaning schedules & possibly using adjustable tilt mounts. This makes Bicol Region, Philippines a good location for solar energy production year-round.

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.

Solar output per kW of installed solar PV by season in Bicol Region

Seasonal solar PV output for Latitude: 13.2453, Longitude: 123.5698 (Bicol Region, Philippines), 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:

Average 5.60kWh/day in Summer.

Average 4.74kWh/day in Autumn.

Average 4.08kWh/day in Winter.

Average 6.25kWh/day in Spring.

Ideally tilt fixed solar panels 11° South in Bicol Region, Philippines

To maximize your solar PV system's energy output in Bicol Region, Philippines (Lat/Long 13.2453, 123.5698) 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: 13.2453, Longitude: 123.5698, the ideal angle to tilt panels is 11° South

Seasonally adjusted solar panel tilt angles for Bicol Region, 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 Bicol Region, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° 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 Bicol Region, 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 Bicol Region, 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 Bicol Region, Philippines

The Bicol Region in the Philippines is characterized by a diverse topography with coastal plains, valleys, and mountain ranges. It includes active volcanoes like Mount Mayon and Mount Bulusan, as well as several hills and plateaus. The region also has numerous rivers that flow into the sea.

In terms of solar PV potential, flat areas with high sun exposure would be most suitable for large-scale solar farms. Considering this, coastal plains and valleys might be good options given their relatively flat terrain compared to mountains or hilly areas. However, the feasibility of such projects would also depend on factors like land use restrictions, proximity to transmission lines or grids for power distribution.

Specifically looking at Bicol region's geography:

1. Camarines Sur: This province in Bicol has flat lands particularly around Pili which could potentially host large scale solar projects.
2. Albay: While known for its volcanic landscapes due to Mt Mayon, it also has flatter regions especially towards the coast which could be suited for solar PV.
3. Sorsogon: This province has extensive coastline and flatter regions near Sorsogon city which could potentially host large scale solar installations.

However it should be noted that while these are potential sites based on topography alone; other factors such as local climate (cloud cover), land availability/ownership issues etc., need to be thoroughly evaluated before deciding on any specific location for setting up a large scale Solar PV farm.

Also important is assessing existing infrastructure - both physical (roads) and electrical (grid connectivity). The site must have access to adequate transmission infrastructure or plans should include developing necessary infrastructure along with project development.

Finally environmental impact assessments will need to conducted keeping in mind Philippines' rich biodiversity including many endemic species found in this region specifically.
