Solar PV Analysis of Krabi, Thailand
Krabi, Thailand is a good location for solar energy production all year round because it gets a lot of sunlight throughout the year. The amount of electricity that can be generated from solar panels varies slightly with each season, but overall it's quite consistent.
In summer, you can expect to generate about 5.27 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panel installed. In autumn, this drops slightly to 4.75 kWh/day per kW installed. Winter sees an increase to 5.96 kWh/day per kW installed and spring has the highest output at 6.15 kWh/day per kW installed.
The best time of year to generate solar power in Krabi would be during the spring when the output is highest, but even in autumn when it's lowest, you're still getting a decent amount of energy.
If you're installing fixed panel solar installations at this location, tilting them at an angle of 8 degrees South will give you the maximum total yearly production from your panels.
There could be some factors that might reduce how much energy your panels produce though like weather conditions or local environmental issues. For example, if there are lots of trees or buildings around that cast shadows on your panels then they won't work as well because they need direct sunlight to operate efficiently.
Also keep in mind that while Krabi does get a lot of sun over the course of a year due its tropical location; heavy rainfall during monsoon seasons could potentially decrease solar output temporarily due to cloud cover and less sunshine hours during those periods.
To prevent these issues affecting your energy production too much: make sure your panels are positioned where they'll get as much sunlight as possible throughout the day and aren't likely to be overshadowed by anything; install them securely so they can withstand heavy rainstorms without being damaged; consider using tracking systems that follow the sun’s path across sky for maximum exposure; and keep the panels clean, since dust or debris can block sunlight and reduce efficiency.
Overall though, Krabi is a pretty great place to generate solar energy despite these potential challenges.
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 Krabi
Seasonal solar PV output for Latitude: 8.0733, Longitude: 98.9135 (Krabi, 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:
Ideally tilt fixed solar panels 8° South in Krabi, Thailand
To maximize your solar PV system's energy output in Krabi, Thailand (Lat/Long 8.0733, 98.9135) throughout the year, you should tilt your panels at an angle of 8° 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 Krabi, 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 Krabi, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° North in Summer | 14° South in Autumn | 23° South in Winter | 2° 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 Krabi, 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 Krabi, Thailand.
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 Krabi, Thailand
Krabi, Thailand is located on the western coast of southern Thailand and is characterized by a mixture of flat plains and hilly terrains. The area is surrounded by beautiful limestone cliffs, offshore islands, mangrove forests, and numerous rivers that flow into the Andaman Sea.
The climate in Krabi is tropical with high temperatures and humidity levels throughout the year. It has two main seasons – dry (November to April) and rainy (May to October).
For large-scale solar PV projects, flat areas would be most ideal as they require less groundwork preparation than hilly or mountainous terrain. In Krabi province, these could potentially include areas around Nuea Khlong or Klong Thom districts where there are larger expanses of flatter land available.
However, several factors need to be considered when determining suitability for large-scale solar PV including land availability & price, proximity to transmission lines & grid infrastructure for electricity distribution as well as local regulations regarding land use.
Additionally considering environmental impact assessments are crucial especially in an ecologically diverse region like Krabi which hosts national parks & protected marine reserves. Solar farms can have potential impacts on local ecosystems through habitat loss or alteration so careful site selection minimizing ecological disruption should be a priority.
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.
