Are power optimizers in a solar system worthwhile?

Equipping the solar system with power optimizers can be worthwhile in various cases. However, a detailed analysis of the local conditions by a solar technician is advisable in order to find the best possible solution for the individual situation. 

There are some situations in which the use of power optimizers makes sense to compensate for possible performance losses.

Shading: If certain solar modules are permanently and heavily shaded, the purchase of an optimization system can be worthwhile. However, if the shading is minor, the benefit is usually limited.

Different tilt angles: If the modules have different tilt angles, this affects the irradiation and consequently the maximum power point (MPP). This is where PV power optimizers can help to achieve the best possible yield.

Different modules: If a PV system consists of different modules, for example due to retrofitting, a solar optimizer can also be useful to achieve optimal yields.

Furthermore, equipping the solar plant with an optimizer can also be useful if easy monitoring and remote maintenance of the plant is desired. This is particularly relevant when multiple systems are operated at different locations. The use of performance optimizers can reduce the maintenance effort, since potential problems can be detected and corrected at an early stage.

A comprehensive analysis of the individual circumstances as well as professional advice are crucial to determine whether the installation of power optimizers makes economic and technical sense.

Advantages of solar power optimizers: yield optimization, easy monitoring and flexibility

Solar power optimizers offer several advantages that should be considered when deciding to install a solar system:

Higher yield: PV power optimizers have the potential to increase the yield of the solar system. Primarily used in situations where varying irradiation conditions would affect the performance of multiple modules, individual control and optimization of modules can maximize output. As a result, higher energy production can be achieved.

Easy monitoring: power optimizers are usually installed with appropriate software that simplifies monitoring of the system via cell phone or computer. This allows individual retrieval and verification of the performance of each module. Detailed monitoring allows defects or performance degradation to be detected and corrected more quickly, resulting in improved solar system efficiency.

Flexibility: Depending on the optimization system used, solar power optimizers offer increased flexibility in the planning and design of the solar system. Different module types, orientations and inclinations can be combined. This enables optimal use of the available roof area and opens up possibilities for possible retrofits. Modules that are subsequently installed - whether to expand the system or to replace defective modules - do not necessarily have to match the original modules. Flexibility in the selection and combination of modules facilitates the adaptation of the solar system to individual requirements and enables more efficient use of the available resources.

Disadvantages of power optimizers: costs, repair costs and increased energy consumption.

The decision to upgrade a solar system with power optimizers should be carefully considered, as there are also some disadvantages that need to be taken into account:

High initial costs: installing power optimizers means additional costs for the solar system. At around €50* per module, the initial cost can increase significantly. It is therefore advisable to check in advance whether these costs will be recouped by a significantly higher yield from the system.

Higher repair costs: When using power optimizers, there is also the risk of breakdowns or defects. In the event of damage, repair costs can increase accordingly. It is important to consider this when deciding on power optimizers and, if necessary, to take appropriate measures to ensure the longevity and reliability of the optimizers.

Increased energy consumption: Power optimizers require energy to function. This energy is drawn from the solar panels. Therefore, installing PV power optimizers also increases power consumption, albeit slightly. It is important to check whether the additional energy requirement is profitable in relation to the expected yield of the system.

It is important to note that the disadvantages mentioned do not occur in every case and depend on the individual circumstances of the solar system. In some cases, the advantages of power optimizers may outweigh the disadvantages. A detailed analysis of the specific requirements and economic aspects of the plant is therefore essential.

*The costs mentioned are only an example and may vary depending on the manufacturer and region. It is advisable to obtain specific quotations and seek advice from a specialist.

Alternatives to power optimizers, the ShadeFix from SMA

The ShadeFix from SMA is an innovative solution for optimizing the yield of solar modules, especially in the case of partial shading. Unlike conventional power optimizers, the ShadeFix operates at string level and enables intelligent control of module currents. Here is an overview of how the ShadeFix works and its advantages and disadvantages:

How the ShadeFix works:

  • String-level optimization: the ShadeFix works at the string level instead of optimizing individual modules. This means that the ShadeFix analyzes the behavior of the entire string and intelligently controls the current flows of the individual modules.

  • Dynamic current limiting: The ShadeFix dynamically limits the current flow of the partially shaded modules. This maximizes the current output of the optimally operating modules while minimizing the power losses of the shaded modules.

  • No additional components: Unlike power optimizers, the ShadeFix requires no additional components on the modules. This simplifies installation and reduces installation costs.

Advantages of the ShadeFix:

  • Cost-effective: the ShadeFix offers a cost-effective solution for optimizing solar modules. String-level control eliminates the need for expensive individual optimizers for each module.

  • Simplified installation: Since no additional components are required on the modules, installation of the ShadeFix is simple and straightforward. This saves time and installation costs.

  • Reliability: Due to its string-based optimization, the ShadeFix offers high reliability. There are fewer components that can potentially fail, which reduces maintenance and service requirements.

Disadvantages of the ShadeFix:

  • Limited precision: compared to power optimizers that operate at the module level, the ShadeFix cannot provide the same precision in power optimization. The performance of the shaded modules is limited instead of optimizing them individually.

  • Limited use with heavy shading: the ShadeFix is most effective with partial shading. For heavy shading, power optimizers that provide individual module optimization may provide a better solution.

In conclusion, SMA's ShadeFix is a cost-effective solution for optimizing solar module yield in partially shaded conditions. While it offers some advantages, such as simplified installation and lower cost, it is important to note that it does not offer the same precision and adaptability as traditional module-level power optimizers. The choice between the ShadeFix and power optimizers depends on the specific requirements of the solar installation and the degree of shading. It is recommended to perform a detailed analysis of the individual situation and, if necessary, to consult a professional to find the best solution for the specific solar installation.
