Himamaylan, Western Visayas, Philippines is a pretty good spot for generating solar energy all year round due to its location in the tropics where sunlight is consistent throughout most of the year. The amount of electricity you could expect from each kilowatt of installed solar varies slightly by season: it's highest in spring (6.45kWh/day), followed by summer (5.62kWh/day), autumn (5.16kWh/day) and winter (4.93kWh/day). So, if you're planning to install solar panels here, you'll get the most bang for your buck during spring.

When installing these panels, pointing them 9 degrees South would be ideal as this position maximizes total yearly production from the solar PV system.

However, there are some local factors that might affect how much energy you can generate with your panels - but don't worry too much because they aren't major issues! One possible factor could be weather conditions such as heavy rain or typhoons which are common in this region; these could potentially damage your panels or block sunlight needed for power generation.

To protect against these potential problems, it's important to make sure that your panels are securely mounted and designed to withstand strong winds and heavy rains. Regular maintenance checks will also help ensure they're functioning properly despite any adverse weather conditions.

In conclusion, Himamaylan is a great place for harnessing solar power with just minor considerations regarding weather conditions that can easily be managed through proper installation and maintenance practices.

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.

Solar output per kW of installed solar PV by season in Himamaylan

Seasonal solar PV output for Latitude: 10.1003, Longitude: 122.8677 (Himamaylan, 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 5.62kWh/day in Summer.

Average 5.16kWh/day in Autumn.

Average 4.93kWh/day in Winter.

Average 6.45kWh/day in Spring.

Ideally tilt fixed solar panels 9° South in Himamaylan, Philippines

To maximize your solar PV system's energy output in Himamaylan, Philippines (Lat/Long 10.1003, 122.8677) throughout the year, you should tilt your panels at an angle of 9° 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: 10.1003, Longitude: 122.8677, the ideal angle to tilt panels is 9° South

Seasonally adjusted solar panel tilt angles for Himamaylan, 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 Himamaylan, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° 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 Himamaylan, 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 Himamaylan, 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 Himamaylan, Philippines

Himamaylan, Philippines is located in the coastal plains of Negros Occidental province. The area has a mixed topography with flatlands along the coast and hilly to mountainous areas towards the interior. The region is known for its fertile soil, making it ideal for agriculture.

Regarding solar PV installations, flat regions are typically more suitable as they require less site preparation and can accommodate larger arrays. So, coastal plains around Himamaylan could be potential locations for large-scale solar PV systems.

However, other factors should also be considered when choosing a location for large-scale solar power plants such as:

1. Solar irradiance: This refers to the amount of sunlight available in the area which can vary depending on local weather conditions and time of year.
2. Land use: Areas not currently being used for agriculture or habitation would be preferable to minimize disruption.
3. Proximity to power grid: To efficiently deliver generated electricity to consumers.
4. Environmental impact: Potential effects on local ecosystems should also be assessed.

Overall, a detailed feasibility study including these factors should be conducted before deciding on an exact location within this region for setting up a largescale solar PV system.

Philippines solar PV Stats as a country

Philippines ranks 40th in the world for cumulative solar PV capacity, with 1,370 total MW's of solar PV installed. Each year Philippines is generating 13 Watts from solar PV per capita (Philippines ranks 71st in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Philippines?

Yes, there are several incentives for businesses wanting to install solar energy in the Philippines. These include:

1. The Feed-in Tariff (FiT) program, which provides a guaranteed rate of return on investments in renewable energy projects;

2. Tax credits and exemptions from certain taxes;

3. Net metering programs that allow businesses to sell excess electricity back to the grid;

4. Grants and loans from government agencies such as the Department of Energy and the Philippine Solar Power Alliance;

5. Technical assistance from organizations like USAID’s Clean Energy Program; and

6. Access to financing through banks, venture capital firms, or other sources of private capital.
