Solar Panels Are Partially or Fully Shaded at Certain Times.
If one panel in a solar system is shaded, energy production is significantly affected. So, if you constantly experience even partial shading, you should seriously consider solar optimisers.
These optimisers will ensure that unshaded panels operate optimally while also providing the best possible power output from the shaded panel.

With Australia located in the southern hemisphere, the sun’s direction moves towards the north.
Thus, north-facing solar panels deliver the best output. East and west-facing panels will reduce output by 10 – 20%, while north-facing panels can reduce output by roughly 28%.
That said, if your complicated roof causes your solar panels to face different directions, you will certainly benefit from optimisers, as they can maximise the output of your panels.

DC power optimizers are electronic devices housed in small plastic boxes located under each solar panel in an array. They ensure that each solar panel in an array is operating at its maximum potential to increase the conversion rate and efficiency for DC to DC energy.
Power optimizers work in conjunction with a central string inverter, which converts the DC power output of solar panels into AC power that can be used in your home. In an array without power optimizers, a string of solar panels can experience reduced power output when only one panel is shaded.
If you have partially shaded conditions or need to install solar panels with multiple orientations to the sun, power optimizers can be a smart option and may be a better fit for your needs than microinverters. While microinverters address the same shading and roof orientation challenges as power optimizers, they are more expensive to install.
When solar panels are exposed to sunlight, they generate DC power, which is typically sent to a central string inverter. This inverter then converts the electricity into AC power for household use.
While this setup is effective for most solar systems, it can lead to reduced power output in cases of partial shading or multiple panel orientations.
In such scenarios, the productivity of the entire panel string is limited by the performance of the least effective panel. Issues such as shading from trees and clouds, dirt, bird droppings, and component failures can cause a decrease in the productivity of the entire group. Defective or shaded panels may produce significantly less solar energy, up to 50 percent in some cases, compared to other panels. By using optimizers, each panel can be managed separately, ensuring that the productivity of each solar panel is maximized.
Under challenging solar installation conditions, the maximum power output of each panel varies due to factors such as temperature, sunlight, and electrical load characteristics. These factors differ across the array when panels face multiple directions or are shaded. Power optimizers address this issue by utilizing a technique called Maximum Power Point Tracking (MPPT).
It’s worth noting that optimizers also contribute to electrical safety. HIITIO, a pioneer in the optimizer market, has introduced a Rapid Shutdown function that automatically reduces the high DC voltage of the modules to a safe level when the inverter or mains power is switched off, ensuring maximum safety. Optimizers enable early detection of potential problems and malfunctions with solar panels.
Maximum power point tracking (MPPT), sometimes referred to as power point tracking (PPT), is a technique used in variable power supplies to maximize the amount of energy extracted as conditions change and is most commonly used in photovoltaic solar systems.
Photovoltaic solar systems vary in their relationship to the inverter system, the external grid, the battery bank, and other electrical loads.
Mppt addresses the central issue that the power transfer efficiency of a solar cell depends on the amount of available sunlight, shading, solar panel temperature, and the electrical characteristics of the load.
As these conditions change, so do the characteristics (impedance) of the load that provides the highest power transfer. As the load characteristics change, the system is optimized to maintain the highest efficiency power transfer. This optimal load characteristic is referred to as the Maximum Power Point (MPP.) MPPT is the process of adjusting the load characteristic in response to changing conditions.
MPPT technology continuously monitors the output of the solar panels and adjusts the operating conditions to maintain the panels at their maximum power point. By dynamically adjusting the voltage and current to match the optimal operating point, MPPT maximizes the power output of the solar panels, resulting in increased energy production and improved overall system efficiency.
In essence, MPPT technology ensures that the solar panels are always operating at their peak performance, allowing for the extraction of the maximum amount of power from the available sunlight.
Solar optimizers are beneficial in several scenarios, including:
In installations where solar panels are subject to partial shading from trees, buildings, or other obstructions, solar optimizers can help mitigate the impact of shading by allowing each panel to operate independently at its maximum power point.
If solar panels are installed with varying orientations, such as facing different directions, solar optimizers can optimize the performance of each panel individually, ensuring maximum energy production.
In systems with panels of different makes, models, or ages, solar optimizers can help overcome the mismatch issues by individually managing the output of each panel.
Solar optimizers provide advanced monitoring capabilities, allowing for the early detection of potential problems and malfunctions with solar panels. This can help in proactive maintenance and ensuring the long-term performance of the system.
Some solar optimizers, such as those with Rapid Shutdown functionality, enhance electrical safety by automatically reducing the high DC voltage of the modules to a safe level when the inverter or mains power is switched off.
Both microinverters and power optimizers enable the monitoring of individual PV modules, providing insights into the performance of each module within the solar array.
Both microinverters and power optimizers address challenges related to suboptimal lighting conditions, such as shading or indirect sunlight, by maximizing the DC output of PV panels to enhance overall energy production.
Installation costs for microinverters are typically higher than those for power optimizers due to the more intricate circuitry of microinverters. Additionally, microinverters are bulkier and have a higher risk of lightning strikes compared to power optimizers.
In terms of functionality, microinverters convert DC to AC power, while power optimizers solely condition DC energy before it is transmitted to a solar inverter.
Scalability differs between systems with microinverters and those with optimizers. Systems with power optimizers face limitations in scalability due to their dependence on a central inverter, which has constraints on the amount of power it can handle.
Microinverters generally require more maintenance than power optimizers. While the lifespan of microinverters can vary from 5 to 12 years, power optimizers can last for nearly 25 years, twice the lifespan of microinverters.
However, it’s important to note that microinverters are less likely to impact the overall system performance compared to optimizers. This is because an optimizer system relies on a central inverter, and if an optimizer fails, it is likely to affect the inverter and, consequently, the entire system.
For those with an established solar power system, it’s crucial to consider the quantity and wattage of optimizers required. Inverters are designed to limit the AC power conversion level. If DC power is boosted using optimizers, the inverter’s capacity to convert AC power may be exceeded. While the inverter can still operate with a higher payload, excess electricity can potentially shorten its lifespan.
Similar to solar panels, power optimizer systems vary in efficiency. Efficiency measures the energy lost as heat during the conversion from DC to AC electricity. The solar inverter integrated with the system also contributes to overall system efficiency and solar electricity production, whether power optimizers are used or not.
Power optimizers are available in different sizes to handle varying maximum voltages, aligning with the wattage rating of the modules. For instance, a 300-Watt panel would typically use a 320-Watt power optimizer. It’s essential to pair a matching-sized inverter with the selected power optimizer. The capacity of the optimizer dictates the required inverter capacity. However, it’s important to avoid selecting an inverter or optimizer that is undersized for the system, as their sizes are influenced by the energy output of the solar panels.
In a residential installation with an optimized system, one power optimizer is needed per solar panel, while commercial installations may have one optimizer for every two panels. The cost is influenced by both the quantity of optimizers and the warranty periods offered by different brands. Typically, a longer warranty is associated with a higher price tag.
