More energy from every solar module

In traditional PV systems, when solar panels are connected in series (in a string), the total power of the system is determined by the weakest module. This means that if even just one panel in the string has reduced efficiency, it limits the performance of all the other modules. There are several reasons for this:

Mismatch in production tolerance:

Solar module manufacturers specify the rated power of each panel, but in real-world conditions this power varies. Even with the same model and manufacturer, each panel may have small variations in performance. For example, if the difference in manufacturing tolerances is about ±3%, this means that some panels may produce up to 3% less power than others. In a traditional system, this discrepancy results in power losses as the entire string operates at the level of the weakest panel.

Shading, fouling and leaf build-up:

Even partial shading of one panel can have serious consequences for a traditional PV system. When trees, chimneys, antennas or other obstructions cast shadows on part of the panels, this not only reduces the performance of the shaded panel, but also results in a proportional reduction in the power output of the entire string. In addition, debris such as dust, dirt, bird droppings and fallen leaves can block sunlight and reduce energy yield.

Uneven aging of modules:

All PV panels lose some of their efficiency over time. Typically, standard panels have an annual degradation of 0.5% to 0.8%, meaning that after 20 years they can lose between 10% and 16% of their original output. However, different panels age at different rates due to factors such as weather conditions, manufacturing differences and local impacts. In traditional systems where all panels are connected in series, the faster aging panels will slow down the others, resulting in even greater energy losses.

SolarEdge's solution

SolarEdge overcomes all these limitations through its revolutionary module-level power optimization technology. Instead of letting the entire system operate at the level of the weakest panel, SolarEdge uses power optimizers that allow each module to operate independently of the others.

How do power optimizers work?

SolarEdge's power optimizers are intelligent devices mounted on each panel that ensure maximum performance for each individual module. They adjust the voltage and current so that each panel operates at its optimum output without affecting the other panels in the system.

Benefits of SolarEdge Optimizers:

Up to 25% more energy - each module runs at its full capacity without being limited by the others.
Reduced shading and contamination losses - if one module is shaded or contaminated, it does not affect the other panels in the system.
Better use of space - the possibility to install panels with different orientations and inclinations, which optimises energy production
Longer system life - minimising the impact of uneven panel ageing.

Greater safety with SafeDC™

Traditional systems can pose a serious safety risk. In standard string inverter systems, voltages can reach up to 1500VDC (volts direct current), creating potential hazards of electrical shocks, short circuits and fires in the event of improper operation, failure or emergency.

Particularly in cases of maintenance, emergency shutdown or fire, high voltages can pose serious risks to electricians, firefighters and anyone working near the system. Even when the inverter is turned off, traditional systems continue to maintain high voltages across cables and modules, increasing the risk of power surges and uncontrolled arcs.

To minimize these risks, SolarEdge developed SafeDC™, an intelligent safety technology that automatically reduces the voltage of each module to a safe level (1V) in the event of a system shutdown. This ensures that even in an emergency situation the voltage across the cables and modules is at safe levels, reducing the risk of electrical accidents.

When is SafeDC™ activated?

The SafeDC™ function is automatically activated in several key situations, ensuring maximum protection:

When the inverter is switched off - if the inverter is shut down during maintenance or for technical reasons, SafeDC™ automatically reduces the voltage.
When the power grid is shut down - in the event of a power outage or grid failure, the modules automatically switch to safe mode.
During installation and maintenance - when the system is not connected to the inverter or repairs are being carried out, SafeDC™ prevents dangerous voltage build-up.
When high temperature is detected in the modules - if the system detects a temperature above 85°C, it automatically reduces the voltage to prevent potential problems.

This advanced technology provides greater protection for installers, homeowners and emergency crews who can safely operate the system even in unforeseen situations.

Flexibility and adaptability in design

Flexibility and adaptability in the design of solar systems play a key role in the efficiency and aesthetics of the installation. SolarEdge offers innovative solutions that enable better distribution of solar panels, maximizing the use of available space and reducing the technical constraints often found in traditional PV systems.

Thanks to power optimizers, SolarEdge's systems allow maximum use of roof space. This means that panels can be deployed in different configurations without reducing the overall efficiency of the installation. Even if part of the roof is shaded at certain times of the day or there are architectural obstructions such as chimneys and dormers, the system will operate optimally as each panel functions independently of the others.

Another advantage of the technology is the possibility of installations on roofs with different slopes and orientations. In traditional systems, all the panels in a string must be positioned in the same direction and at the same angle to avoid power loss. With SolarEdge, this constraint is dropped, allowing for more flexible system design and maximum use of available roof area. This is particularly useful for buildings with non-standard architecture or with roof segments located in different directions.

Full real-time monitoring and control

Full real-time monitoring and control is one of SolarEdge's greatest benefits, providing solar system owners with a detailed view of each individual panel's performance, inverter efficiency and overall energy output. This not only allows for better system management, but also significantly improves system reliability and long-term efficiency.

One of the key capabilities of SolarEdge's monitoring platform is the tracking of each individual module. In traditional PV systems, only the overall inverter performance is typically monitored, making it difficult to detect problems with individual panels. SolarEdge's system, however, provides detailed analytical data on the performance of each module individually, allowing quick and accurate detection of potential energy losses caused by shading, contamination or technical faults.

In addition, the platform sends automatic error alerts that help owners and installers respond immediately when a problem occurs. In the event of a panel malfunction or reduced efficiency, the system automatically generates a notification and provides specific information about the location and nature of the problem. This not only saves diagnostic time and cost, but also minimizes energy waste by allowing faster remedial action.

Access to the platform is simple and intuitive, and monitoring can be carried out via a mobile app available for smartphones and tablets. This means that homeowners can monitor both current energy production and household consumption in real time, anytime and from anywhere.

SolarEdge Intelligent Modules

SolarEdge smart modules are an innovative solution that combines solar panels with built-in power optimizers. This provides higher efficiency, easier installation and improved control of the entire PV system. The built-in optimiser allows each module to operate independently of the others, removing traditional constraints associated with shading, pollution or power differences between individual panels.

One of the main advantages of SolarEdge smart modules is faster and easier installation. Thanks to the pre-integrated optimizers, the installation of the system is simplified considerably as there is no need to add additional power optimization devices. This not only reduces the time required for installation, but also reduces potential errors and makes the whole process more efficient. With fewer components to connect, installers can complete more projects in a shorter period, improving the cost-effectiveness of the installation.

As well as making installation easier, these modules also make maintenance significantly easier. Built-in power optimizers enable remote monitoring and diagnostics, meaning potential problems can be detected and analyzed without the need for physical on-site inspection. This saves time and service costs by reducing the number of unnecessary visits by technicians. In the event of a fault, the monitoring platform provides detailed information about the specific module that has the problem, allowing for quick and accurate troubleshooting.

Another key advantage of SolarEdge's smart modules is their ability to produce more energy and have a longer service life. Thanks to module-level optimization technology, each panel operates at maximum efficiency regardless of environmental conditions. Even if some panels are shaded, dirty, or have varying degrees of aging, the system will provide optimal energy production without being limited by the weakest module. This results in a higher power yield over the lifetime of the system.

Smart modules are created with high quality materials and undergo rigorous testing for durability and sustainability. They have extended warranty periods and are designed to withstand adverse weather conditions such as high temperatures, high winds and snow accumulation.
