1. What are Microinverters?

Microinverters are small-scale, module-level power electronics used in solar power systems that convert the direct current (DC) generated by a single solar panel into alternating current (AC). They offer an alternative to traditional string or central inverters and are designed to optimize the energy output of individual solar panels, ensuring optimal performance even under varying sunlight conditions or partial shading.

2. Features of Microinverters

• Maximum power point tracking (MPPT): Each microinverter is equipped with its own MPPT, which enhances solar panel efficiency by continually adjusting the conversion process to maximize energy output.

• Module-level monitoring: Microinverters enable real-time monitoring and performance tracking of individual solar panels, allowing system owners to detect and address any issues promptly.

• Enhanced system reliability and safety: With microinverters, a malfunctioning panel or inverter won't affect the performance of the entire system, making it more reliable and safer than traditional string inverter systems.

• Simplified system design: Microinverters eliminate the need for complex string inverter calculations and compatibility issues, making solar power system planning and installation simpler and more flexible.

3. Applications of Microinverters

• Residential solar installations: Homeowners can benefit from microinverters as they optimize individual solar panel performance, improve system reliability, and enable real-time monitoring.

• Small-scale commercial solar installations: Businesses with limited roof space or shading issues can take advantage of microinverter systems for enhanced energy yields and system stability.

• Building-integrated photovoltaic (BIPV) systems: Microinverters are particularly suitable for BIPV systems, which require complex design considerations and may include panels with varying exposure to sunlight.

4. Market Demand for Microinverters

The market demand for microinverters is expected to grow substantially as solar power system owners increasingly seek advanced technologies to optimize system performance, reliability, and safety. The global microinverter market is projected to grow at a Compound Annual Growth Rate (CAGR) of approximately 15% between 2021 and 2028.

5. Market Share of Microinverters

Although microinverters represent a relatively small portion of the overall solar inverter market, their market share is anticipated to increase rapidly as consumers and installers recognize the numerous benefits they offer. As the solar power industry continues to grow, microinverters are expected to capture a larger share of the market.

6. Price Trends of Microinverters

In recent years, the cost of microinverters has declined due to technological advancements, increased production capacity, and economies of scale. The price reduction has made them more competitive with traditional string inverters. As the solar power market grows and technological advancements continue, prices for microinverters are expected to fall further, making them an increasingly attractive option for consumers.
