Power optimizers - more energy, more control

Power optimizers are an indispensable component of modern photovoltaic systems. These innovative devices work at module level and ensure that each module achieves maximum output independently - even with shading, different inclinations or unequal module types. The result: higher energy yields and maximum efficiency.

SolarEdge combines inverters and power optimizersinto a perfectly matched system. Their optimizers offer 99.5 % efficiency, module-specific monitoring and an increase in energy yield of up to 25 %. They are particularly suitable for systems with complex roof structures or partial shading. Huawei Smart PV Optimizers are characterized by intelligent fault detection and integrated safety functions. With a maximum input voltage of up to 80 V, they optimize both small and large systems and ensure reliable performance and safety. Tigo Energy' s modular optimizers make it easy to retrofit existing systems. Their solutions are compatible with various module types and sustainably increase energy efficiency.

Power optimizers are the ideal choice for making your PV system efficient, flexible and future-proof.

What is a power optimizer?

A power optimizer is a device that is used in solar installations to maximize the output of each individual solar module. In a solar installation, different modules can produce different amounts of energy due to factors such as shading, different orientations or soiling. The power optimizer monitors the output of each module and ensures that each module delivers its maximum energy by adjusting the voltage and current of each module. This increases the overall yield of the solar system and reduces losses that could be caused by less powerful modules. Power optimizers are particularly useful in systems where not all modules are evenly aligned or in areas with partial shading.

The advantages of optimizers for solar systems:

Increased energy production: Power optimizers maximize the output of each individual module, increasing the overall energy yield of the solar installation, especially in cases of uneven orientation or partial shading.
Better performance in partial shading: They minimize the impact of shading on individual modules as each module is optimized independently, increasing the efficiency of the entire system.
Easy fault diagnosis: Power optimizers allow precise monitoring of each module's performance, making it easier to identify and resolve problems.
Increased system reliability: As the optimizer regulates the current flow of each module, the risk of power loss or damage due to faults in individual modules is reduced.
Expandability: Power optimizers offer more flexibility when a solar installation is expanded or modified in the future, as they allow better adaptation to different modules or new system configurations.

Advantages of power optimizers for installers and end customers

Installers

Easy installation: Power optimizers are easy to integrate and do not require complex modifications to the existing system. They can be installed quickly without having to redesign the entire solar system.

Fault diagnosis and maintenance: Installers can quickly identify and rectify faults by precisely monitoring each module, which simplifies maintenance and reduces downtime.

Increased customer satisfaction: By improving the efficiency of the solar system and reducing power losses, installers can offer their customers higher performance and a better long-term return on investment.

Better adaptation to difficult conditions: Installers can optimize solar installations in areas with partial shading or complex module placement, as the power optimizers adjust the output of each module individually.

Increased flexibility in planning: Installers can consider more options when aligning and placing modules, as the power optimizers ensure that each module works independently of the others.

End customers

Higher energy yield: By optimizing the performance of each module, end customers achieve higher overall energy production, even if some modules are less efficient due to shading or orientation.

Long-term cost savings: The increased energy production leads to a better return on investment for the solar system, allowing end customers to reduce their energy costs in the long term.

Longer system life: As performance optimizers adjust the output of each module, they can help make the solar system more efficient and durable by preventing damage and unnecessary stress on individual modules.

Easy monitoring: End customers can often monitor the performance of each module via an app or web interface, providing more control and transparency over the operation of the solar installation.

Better adaptation to future requirements: If end customers want to expand or change their solar installation, performance optimizers offer the flexibility to easily add new modules or adjust the system without having to redesign the entire installation.

Power optimizers: technology and benefits in detail

Technology:
Power optimizers monitor and optimize the performance of each solar module by adjusting the direct current (DC) generated and regulating the voltage and current of each module individually.

Maximum energy production:
They maximize energy production, even with partial shading, uneven alignment or soiling, by optimizing each module independently and thus avoiding power losses.

Fault diagnosis:
Module-based monitoring allows defects and power losses to be quickly identified and localized, simplifying maintenance and reducing downtime.

System reliability:
Power optimizers prevent the overloading of individual modules, which extends the service life of the entire solar system and maintains its efficiency in the long term.

Flexibility:
They offer more design options during installation, especially in complex situations, as modules also work optimally under different conditions (e.g. shading, different orientation).

Expandability:
Power optimizers make it easy to expand an existing solar system, as they enable the integration of new modules without having to make any adjustments to the entire system.

Profitability:
By optimizing each module, yields are increased, resulting in faster amortization of the solar system and long-term cost reductions for the end customer.

Long-term performance:
Performance optimizers help ensure that the solar system operates at optimal performance over a longer period of time by minimizing losses and degradation.
