The solar PV inverters market is expected to register a CAGR of 4.73% during the forecast period, 2022-2027 reaching the value of USD 15.5 billion in 2021 from USD 12.23 billion in 2020. With the COVID-19 outbreak in Q1 of 2020, the solar PV inverters market was moderately impacted. The market growth declined due to the lockdown with delays in manufacturing new inverters, capacity addition outlook, and financial challenges for the major player’s value chain. Factors such as supportive government initiatives and investment in electrification of the remote and rural areas using solar energy are likely to support the solar PV inverters market. However, lack of general awareness, infrastructure development costs, and recent subsidy cuts on solar panels by governments in the Asia-Pacific region is expected to hinder the market growth during the study period.

Key Highlights
Central Inverters have dominated the market in the past and is expected to grow during the forecast period.
Solar PV inverter manufacturers strive for continuous technological developments, including optimized product operations, flexibility, and efficiency. This factor is expected to create immense opportunities for the solar PV inverter market in the near future.
Asia-Pacific is expected to be the fastest and largest growing market during the forecast period, with the majority of the demand coming from countries like China, India, etc.

Key Market Trends

Central Inverters Segment Expected to Witness the Market

A central inverter is a large grid feeder. It is often used in solar photovoltaic systems with rated outputs over 100 kWp. Typically, floor or ground-mounted inverters convert DC power collected from a solar array into AC power for grid connection. These devices range in capacity from around 50kW to 1MW and can be used indoors or outdoors.
Generally, a central inverter consists of one DC-AC conversion stage. Some inverters also have a DC-DC boost stage to increase their MPP (Maximum Power Point) voltage range. Low-frequency transformers are sometimes used to boost the AC voltage and provide isolation at the output. However, this reduces efficiency and increases the inverter’s size, weight, and cost.
A central inverter typically has a maximum input voltage of 1,000V. However, some newer central inverters already come with 1,500V input voltage. These inverters allow PV arrays based on a maximum voltage of 1,500V, requiring fewer BOS (balance of system) components.
Central Inverters can be monolithic (using a single power train and multi-MPPT tracker) or modular (using multiple power trains). Modular inverters are more complex but can maintain reduced power output if one or more modules fail and can use either a multi-MPPT or a master-slave control approach. The multi-MPPT system uses a separate converter and MPPT for each floating sub-array, increasing the overall energy harvest under partial shading conditions. In the Master-Slave approach, the Controller module is always on. It commands the slave modules (the slaves) to switch on when more power is available from the array, which maximizes inverter efficiency in low-insolation environments.
As central inverters are used for utility-scale applications, they should produce the same voltage and frequency as that of the electric grid where they are used. As there are a lot of different electric grid standards worldwide, manufacturers are allowed to customize these parameters to match the specific requirements in terms of the number of phases; most central inverters manufactured are three-phase inverters.
In January 2022, Sungrow launched its new “1+X” central modular inverter with an output capacity of 1.1MW at the World Future Energy Summit in Abu Dhabi. This 1+X modular inverter can be combined into eight units to reach a power of 8.8MW and features a DC/ESS interface for the connection of energy storage systems (ESS).
Therefore, with the growing demand for electricity coupled with the government’s efforts to decarbonize the power sector and declining costs of central inverters are expected to drive the segment in the coming years.

Asia-Pacific to Dominate the Market

The Asia-Pacific region dominated the solar PV inverter market in 2021, and it is expected to continue its dominance over the coming years. Most of the demand is expected to come from China, which is also the largest producer of solar energy in the world.
In China, there has been an increased emphasis on solar inverters, providing a Zero-voltage Ride Through (ZVRT) scheme. To meet the scheme norms, the solar PV power plants must continue to operate without breaking. This is even more significant as the country hosts the largest amount of solar power generation globally.
With the rising pollution concerns worldwide due to industrialization, especially in Asia-Pacific, regional solar power generation has gained considerable momentum. As part of the Paris Agreement commitments, the Government of India set an ambitious target of achieving 175 GW of renewable energy capacity by 2022. Out of the 175 GW, 100 GW was earmarked for solar capacity with 40 GW (40%), which was expected to be achieved through decentralized and rooftop-scale solar projects. To achieve this huge target, the government launched several new programs in 2019, like the solar rooftop phase-2, PM-KUSUM, and the development of ultra mega renewable energy power parks (UMREPPs).
India’s solar potential is more than 750 GW, and the country’s energy security scenario 2047 shows a possibility of achieving around 479 GW of solar PV installed capacity by 2047. The solar power in India, bestowed with high solar irradiance, has already achieved grid parity that encourages the adoption of solar power as a mainstream energy source, pushing forward the capacity installations in the utility-scale and rooftop solar segments.
As of November 2021, Sungrow Power Supply Co. Ltd had shipped more than 10 GW of solar inverters in India since its operations in the market in 2014. This is due to the increased demand for solar energy across the country.
In March 2022, Sungrow announced that it had increased its fab capacity in India to 10GW/annum capacity. Such large development in the manufacturing sector is expected to have a positive impact on the growth of the market during the forecast period.
Therefore, with various government initiatives launched by China, India, Malaysia, etc., the Asia-Pacific region is expected to dominate the solar PV inverter market during the forecast period.
