The Development Prospects Of Solar Power Inverter In Thailand

As a Southeast Asian country full of sunlight resource, Thailand's solar energy market has developed tremendously. It plays an important role in the market potential of Southeast Asia. The impact of relevant policies on the overseas layout of domestic photovoltaic companies is also worthy of attention. The Thailand solar inverter market has played an important role in the past few years. As key equipment solar system in thailand, the market demand for solar inverter in Thailand has also grown. Next, Xindun will discuss the market and future development prospects of Thailand's solar energy market.

I. Development of Thailand's solar energy industry

Thailand – an important market for green renewable energy

As a developing country in Southeast Asia with a large number of rural areas, Thailand also shows great potential for photovoltaic applications of solar inverter in rural areas. The Thai government's support for solar power projects and the growing awareness of environmental protection have caused more homes and businesses to turn to solar power, thus promoting the growth of solar inverter in the photovoltaic market.

The Thai government regards the development of renewable energy as a national strategy and is committed to increasing the proportion of renewable energy in energy consumption. Further promoting the growth of the solar inverter market and providing more business opportunities for manufacturers and investors, this provides domestic inverter manufacturers with opportunity to expand oversea solar markets.

The market of solar inverter Thailand is in a stage of rapid development, and its market size and demand continue to grow. Government support policies, technological innovation, and international cooperation will further promote market development.

1. How big is the solar energy market in Thailand?

Thailand is one of the important economies in the ASEAN region and the second largest economy in Southeast Asia. According to data from 2023, Thailand's GDP reached 512.193 billion US dollars and its population was about 70 million.

The valuation of Thailand's solar energy market has reached 30 billion baht, mainly concentrated in Bangkok and the central region, mainly for middle and high-income families. It is predicted that about 170,000 homes in Thailand have the need to install solar power systems, which only accounts for 0.8% of the country's 23 million homes. However, Thailand's home solar power market contains hundreds of billions of business opportunities, and at least 2.3 million homes meet the installation conditions. If 20% of them choose to install, a service market worth 137 billion baht will be formed. In addition, Thailand's abundant sunshine resources and reduced costs of key equipment such as solar panels have led more and more families to choose home power supply equipment, especially in the high oil price environment, solar power supply has become a better option to reduce home electricity bills.

2. Geographical conditions and talent cultivation in Thailand

Thailand is located in Southeast Asia and has vast land resources and a population base. Most parts of Thailand have a tropical monsoon climate, characterized by high temperature all year round and distinct dry and wet seasons. Thailand is located near the equator, has long sunshine hours and abundant solar energy resources.

According to statistics, Thailand has sufficient sunlight all year round, with annual radiation of about 1800kW·h/m², and more than half of the areas have a daily radiation of 5.00–5.28kW·h/m². The acceptance of the solar and energy storage markets is very high.

In terms of investment in educational resources, the Thai government keeps up with the international perspective and devotes sufficient resources to talent cultivation. This provides good condition and foundation for the localized construction and operation of solar power projects.

At the same time, Thailand has a good connection with the international market, and has a high degree of acceptance of international cutting-edge technology and various resource information, which is more conducive to the introduction of high-tech technology and funds to develop a localized photovoltaic industry. Among the top ten countries in China's solar power exports in the first quarter of 2023, Thailand ranked fourth with US$655 million, ranking first in Asia.

3. Thailand's electricity and solar storage policies

As one of the largest electricity markets in Southeast Asia, Thailand's electricity consumption reached 222 terawatt hours in 2022. With the rapid development of Thailand's industry, electricity demand has also shown a rapid growth trend. Among them, industrial electricity consumption accounts for the largest share, about 47.4%, followed by commercial electricity, residential electricity and agricultural electricity. The electricity consumption in industrial sectors such as government and non-profit sectors is relatively small.

According to the forecast of Thailand's medium and long-term GDP, population, per capita electricity consumption, electricity elasticity coefficient and other factors, electricity demand is expected to grow at an average annual rate of 2.3%. It is expected that by 2050, electricity demand will reach 403 terawatt hours (about 40.3 billion kwh).

The "2023-2027 Thailand Renewable Energy Market In-depth Research and Analysis Report" pointed out that in recent years, the Thai government has been committed to reducing its dependence on traditional energy and promoting the development of clean energy. To achieve this goal, the government has introduced a series of policies to encourage private and corporate investment in renewable energy.

For example, the Thai government has also implemented a "green certificate" program to encourage the development of renewable energy. The program allows renewable energy power stations to apply for "green certificates", each certificate represents 1 megawatt-hour of renewable energy power. These certificates can be sold on the market to companies or individual who need certificates to encourage more people to use renewable energy. In 2021 (COP 26 Glasgow 2021), the Thai government has vigorously promoted the work of the National Energy Master Plan, striving to achieve the "carbon neutrality" goal in 2050 and achieve net zero carbon emissions in 2065.

According to the regulations of the Thai government, eligible solar power system can enjoy renewable energy power subsidies, known as FIT subsidies. For solar power projects, the subsidy amount per kilowatt-hour is 2.1679 baht, and the subsidy period is 25 years. For light storage power projects, the subsidy amount per kilowatt-hour is 2.8331 baht, and the subsidy period is also 25 years. The implementation of these subsidy policies is aimed at encouraging the development and utilization of renewable energy and promoting Thailand's transition to green energy.

4. The latest solar energy policy in Thailand in 2024

In order to promote the development of the solar energy market, the Thai government actively encourages the public to use solar energy. The Thai government has taken a series of positive measures to promote the development of the solar energy industry in Thailand. Since 2019, the "Residential Photovoltaic Program" has been launched, allowing general residential electricity users to install solar panels on their roofs to generate electricity for their own use, and can sell excess electricity to the national power company.

According to recent Thai media report, the Department of Alternative Energy Development (DEDE) of Thailand said that a new tax reduction plan for home installing rooftop solar panels is expected to be finalized in the middle of the year to reduce electricity bill and carbon dioxide emission. DEDE said that home that purchase solar panels with a power capacity of less than 10 kilowatts at price below 200,000 baht can participate in the plan. The tax reduction calculation will be determined by the Thai Tax Bureau. DEDE expects that 90,000 homes will participate from this year to next year. The plan requires a budget of 20.2 billion baht and can reduce electricity consumption by 585 million kilowatt-hours per year.

Thailand is pushing for energy transformation and diversified development. Clean and renewable energy has accounted for nearly 30% of the country's total power, with biomass power accounting for the majority, followed by hydropower, solar energy in third place, and wind energy in fourth place. The Prime Minister of Thailand said at the 2024 Sustainable Development Forum that Thailand is formulating a power development plan with the goal of increasing the proportion of clean and renewable energy in the country's total power to 50%, while ensuring electrical stability and reducing electricity costs.

5. Thailand's solar energy market has a promising future

However, it should be noted that despite the government's support, the specific subsidy intensity and policy details may change over time and policy changes. Therefore, before entering the Thai market, it is necessary to conduct in-depth investigation and research on local policies.

Low penetration: Although the solar energy storage market is gradually growing in Thailand, the penetration rate is still relatively low. This may be because some home users are not yet aware of and accept solar energy storage system, or because some users have concerns about the cost and complexity of installing and using solar energy system. Therefore, improving the public's awareness and acceptance of solar energy storage system, as well as reducing installation and use costs are the key to promoting further market penetration.

Self-power and self-use: With the development of solar energy storage system technology and the reduction of costs, more and more families are beginning to consider using solar energy systems to meet their energy needs. This self-power and self-use model can not only reduce dependence on traditional energy, but also bring energy cost savings and environmental protection advantage to home users. Therefore, providing solar energy storage system and related service suitable for home use is an important direction for future market development.

Overall, the development trend of Thailand's solar market is strong, and factors such as government support, technological progress and cost reduction have all driven market growth. At the same time, as the Thai public's awareness and acceptance of solar energy systems increases, as well as the cost of installation and use decreases, it is expected that Thailand's solar energy storage market will continue to expand in the next few years, and the market is promising in the future.

Ⅱ.Types of Solar Inverter

Solar inverter is an indispensable and important part of solar power system. Solar inverter is a type of power conversion equipment that is mainly responsible for converting the direct current generated by solar panels into alternating current to meet the needs of household, industrial and commercial electricity.

Solar inverter can be divided into three types according to the usage scenarios, namely off grid solar inverter, on grid solar inverter and hybrid solar inverter. These three types of solar inverter have their own characteristics, advantages and applicable scenarios. How to choose a solar inverter suitable for your own use requires a better understanding of the functions and characteristics of these three types of solar inverter.

1. Off grid solar inverter

Off grid solar inverter is an inverter specially used for off grid solar power system, which converts DC  into AC  for power supply load.

Off grid solar inverter has the characteristics of stable AC output and can store excess power for emergency use. The advantage of off grid solar inverter is that it is suitable for remote areas or scenes without access to the power grid, and can provide reliable power supply.

Off grid inverter is generally suitable for remote areas or places without power grid power supply, such as mountainous areas, deserts, islands, etc. Off grid solar inverter can provide reliable power supply for these areas to meet basic living and working needs. Off grid solar inverter can also be used as a backup power supply to deal with sudden power outage or disaster.

2. On grid solar inverter

For home use, such as rural household, excess power can be sold to the grid to achieve self-sufficiency, energy conservation and emission reduction, and economic benefits. Enterprises can also sell power to the grid for commercial use to obtain benefits and reduce their energy costs and environmental pollution.

3. Hybrid solar inverter

Hybrid solar inverter is an inverter that has both off grid and on grid functions. It can convert the DC power generated by solar panels into AC power for use, and can also convert grid power into DC power for storage. It can switch between off grid and on grid operation modes of solar power system. In the on grid mode, it can sell power to the grid to earn income, and has a mains charging function to charge the battery.

Feature of hybrid solar inverter: It has a bidirectional current flow function, which can realize the mutual complementation and switching of solar energy and the grid to meet the needs of different loads, and can achieve the purpose of self-power and self-use, and surplus power to the grid, so as to maximize the utilization of solar power.

Advantage of hybrid inverter: It can realize dual power supply of solar energy and grid when there is grid power supply, improve energy utilization efficiency, and provide backup power supply in the event of power outage through solar energy storage function.

Hybrid solar inverter is suitable for areas with unstable power supply. They can provide stable power supply through energy storage function to ensure the normal operation of load equipment. For example, rural households can sell the stored excess power to the grid in addition to meeting their own needs, which can not only ensure their own power supply but also earn income.
