Segment Insights
To understand opportunities and where growth is coming from, it helps to look at segments. Here are the key segmentation axes and what recent data shows:
By Product Type / Topology
String inverters: Widely used for residential, commercial rooftop systems. They give good economics and are easier to install.
Micro‐inverters: These are gaining traction especially in residential and small commercial sectors, due to module‐level monitoring, higher yield under shading, etc. Some reports suggest micro‐inverters are among the fastest growing product types.
Central inverters: Favored in utility‐scale installations where high capacities are needed. These account for large shares of market revenues in many projections.
By Capacity / Power Rating / Installation Type
Very small capacities (below 5 or 10 kW) are used in residential or small commercial rooftops. This segment is growing, especially where subsidies or policies favor rooftop solar.
Mid‐range segments (10-50 kW, 50–250 kW etc.) are driven by commercial, industrial, community installations.
Large or utility‐scale (above 1 MW or “central power plants”) rely on central inverters, and their growth is strong in countries pushing large solar farms.
By Connectivity / Grid vs Off‐Grid
On‐grid systems dominate in most developed and increasingly in emerging markets, because grid‐tied solar allows for net metering, feeding excess to grid, etc.
Off‐grid or hybrid systems are important in remote areas, islands, or where grid reliability is low. Growth in mini‐grid and hybrid systems is rising.
Smart inverters (with two‐way communication, better grid support features) are increasingly required by grid codes.
By Application
Residential rooftop solar
Commercial & industrial installations
Utility‐scale solar farms
Sometimes community solar or off‐grid use
By Other Specifications
Phase (single vs three‐phase)
Cooling type (natural, forced air, liquid) – higher power / utility will require more robust cooling.
Output waveform, power efficiency, etc.

Frequently Asked Questions (FAQs)
Q1. What is the difference between string, micro, and central inverters?
String inverters connect a string of solar panels to one inverter; relatively efficient, lower cost per watt especially for rooftops or moderate‐size installations.
Micro inverters are installed at each panel or small grouping; allow module‐level monitoring, better performance under shading, but higher cost per watt.
Central inverters are large units used for utility‐scale or large solar farms; offer economies of scale for large capacity, but are less flexible, more complex in installation and maintenance.
Q2. Which region is likely to see fastest growth?
Asia Pacific is expected to continue leading in absolute size. Emerging markets in APAC (India, Southeast Asia) plus MEA may show highest percentage growth due to low base, favorable solar resources, and increasing policy ambitions.
Q3. What are smart inverters and why are they important?
Smart inverters have enhanced features like two‐way communication, ability to respond to grid disturbances (voltage/frequency), provide ancillary services. They can help with grid stability as PV penetration rises. Grid codes in some countries are mandating such functionality.
Q4. How do policy changes affect this market?
Very strongly. Subsidies, feed‐in tariffs, tax incentives, import/export duties, local content requirements (e.g. requirements to use locally made modules/inverters) all change project economics. Policy uncertainty creates risk, which may slow investment.
Q5. What is the impact of declining component costs?
Lower module and inverter cost reduces the upfront cost of solar systems, making them more competitive with conventional generation. As panels and inverters become cheaper, more projects become viable, increasing demand. However, very low pricing may reduce margins for manufacturers.
Q6. What role do storage and hybrid systems play?
Growing role. As more solar is installed, storage helps in smoothing intermittency and ensuring supply during non‐sunlight hours. Hybrid inverters (PV + battery) reduce complexity for end users compared to separate components. They are increasingly part of new installations.
