Lat Krabang, Bangkok, Thailand is a pretty good place for generating energy using solar panels all year round. This is because it's located in the tropics where sunlight is consistent most of the time and seasons are often characterised by wet and dry periods rather than significant changes in temperature or daylight hours.

If you were to install solar panels here, you could expect to generate on average about 5-6 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panel installed. The best times of year for generating solar power at this location would be during the Spring and Winter when output can reach up to 6.05 kWh/day and 5.97 kWh/day respectively.

For a fixed panel installation at this location, you should tilt your panels towards the South at an angle of 13 degrees. This will ensure that they capture as much sunlight as possible throughout the year, maximising your total yearly energy production from your solar setup.

However, there are some factors that could potentially hinder your solar production in Lat Krabang. These include:

1) Monsoon Seasons: Like many tropical locations, Thailand experiences monsoon seasons which bring heavy rains and cloud cover which can reduce sunlight exposure.
2) Pollution: Urban areas can sometimes have high levels of air pollution which may obstruct sunlight.
3) Dust & Debris: Dust or debris on your panels can block sunlight reducing their efficiency.

To prevent these issues from affecting your energy production too much:
1) Install a sturdy mount system to protect against heavy winds during monsoons.
2) Regularly clean off any dust or debris that collects on the surface of your panels.
3) If possible, choose a location away from sources of pollution like busy roads or factories.

Overall though, with careful planning and maintenance, Lat Krabang offers great potential for harnessing solar power effectively throughout most parts of the year.

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 88 locations across Thailand. 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 Lat Krabang

Seasonal solar PV output for Latitude: 13.7146, Longitude: 100.7805 (Lat Krabang, Thailand), 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 5.91kWh/day in Summer.

Average 5.02kWh/day in Autumn.

Average 5.97kWh/day in Winter.

Average 6.05kWh/day in Spring.

Ideally tilt fixed solar panels 13° South in Lat Krabang, Thailand

To maximize your solar PV system's energy output in Lat Krabang, Thailand (Lat/Long 13.7146, 100.7805) throughout the year, you should tilt your panels at an angle of 13° 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: 13.7146, Longitude: 100.7805, the ideal angle to tilt panels is 13° South

Seasonally adjusted solar panel tilt angles for Lat Krabang, Thailand

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 Lat Krabang, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° 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 Lat Krabang, Thailand

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 Lat Krabang, Thailand.

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 Lat Krabang, Thailand

Lat Krabang is located in the central region of Thailand, near Bangkok. The topography of this area is relatively flat and low-lying, with an average elevation of approximately 2 meters above sea level. This area includes both urbanized areas and agricultural lands.

For large-scale solar PV installations, open and flat areas are typically most suitable as they allow for easy installation and maximum sunlight exposure. In the case of Lat Krabang, the surrounding agricultural lands could potentially be suitable for such installations.

However, it's important to note that using agricultural land for solar PV can lead to conflicts over land use priorities. An alternative might be to consider installing solar panels on rooftops or other built structures in the urbanized parts of Lat Krabang.

Additionally, while the latitude and general climate conditions (tropical monsoon) in Lat Krabang would suggest good potential for solar energy generation - with high levels of sunlight year-round - consideration must also be given to factors like cloud cover and seasonal variations in sunlight intensity.

Before any large-scale project can proceed, a detailed site-specific analysis would need to be conducted to accurately assess the viability and potential productivity of a proposed solar PV installation. Factors such as local weather patterns, shading from nearby structures or vegetation, soil type (for ground-mounted systems), roof angle and orientation (for rooftop systems), grid access/connectivity issues etc., would all need careful examination.

Lastly but importantly one should also consider regulatory policies regarding renewable energy development which may vary across different regions within Thailand.

Thailand solar PV Stats as a country

Thailand ranks 26th in the world for cumulative solar PV capacity, with 3,049 total MW's of solar PV installed. This means that 2.90% of Thailand's total energy as a country comes from solar PV (that's 29th in the world). Each year Thailand is generating 44 Watts from solar PV per capita (Thailand ranks 54th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Thailand?

Yes, there are several incentives for businesses wanting to install solar energy in Thailand. The Thai government offers a number of tax incentives and subsidies for businesses that install solar energy systems. These include a 30% corporate income tax deduction on the cost of installing solar panels, as well as an exemption from import duties on certain components used in the installation process. Additionally, businesses can benefit from net metering policies which allow them to sell excess electricity generated by their solar system back to the grid at a premium rate. Finally, businesses may also be eligible for grants and other financial assistance from various government agencies and private organizations.
