Having taken part in the rapid residential solar market growth in Poland over the last 2 years, APsystems is committed to continue providing innovative microinverter solutions perfectly suited to Polish residential and small-scale commercial demand and helping solar professionals differentiate from competition. The example of the installation company SunUp, based in the Silesian district in Poland, is a good illustration of how the solar installer landscape in Poland is currently evolving towards smarter AC microinverter-based solar solutions to enhance comprehensive services related to PV installations for its customers. It is also a way to address consumer demand more proactively and propose a full energy efficiency solution approach that includes heat pumps together with solar and self-consumption for households .
SunUp background
Let’s take a closer look at SunUp… It all started with its founder, Michał Klimek, who gained extensive experience managing energy projects in Poland and abroad, in Malaysia, Iceland, the United States and Sweden, before setting up his own solar installation company SunUp in Poland in 2019.
Beyond the founder’s ecological awareness, the main trigger pushing Mr Klimek to set up SunUp was the opportunity offered by the utility companies and the Polish government to Polish people to cover most of their electricity needs with solar thanks to an annual billing mechanism reaching over 80% of the self-consumption rate, using the network as a virtual battery system throughout the year.
Two years later, and despite a sensitive period with the pandemic, SunUp boasts over 60 residential and 4 commercial installations completed with APsystems microinverters, reaching over 400 kWp. At the end of 2021, Sunup will complete a 49.95 kWp installation based on APsystems microinverters. In addition to PV installations, SunUp also offers its customers ecological heat pumps that are complementary to PV systems, helping to increase the building’s auto consumption ratio.
A multi-residential project in Rybnik
A recent housing cooperative project located in Rybnik, Poland, is a good example of this green energy transition dynamic. This project consisted in 7 multi-family residential buildings, belonging to the Rybnik Housing Cooperative, which had objectives to reduce energy costs for its investors via its own solar-powered roofs. It was also a way for the housing corporation to contribute to a cleaner way to generate electricity without using fossil fuels, which remain the vast majority of conventional power plants in Poland.
The result is 11 photovoltaic installations for a total project size of approximately 42 kWp.
Mr Klimek explained the main challenges on this project:
“Firstly, we had to look for a safe, reliable solution. During the engineering phase, we realized that we were lacking space inside the building for any traditional string inverters. , the roofs built in the late 70’s each had a slightly different angle and a variety of orientations. The solutions needed a high degree of flexibility… For all these reasons, multi-module microinverters from APsystems appeared to be the best solution we could propose to our customer.”
“Another big advantage with APsystems is that each PV module benefits from its own MPP tracker, so we do not have to worry about any problems that could occur with production for our client. We can easily supervise the production of any PV module remotely. And here we are talking about 106 modules.” He concluded.
The advantages of microinverters
Leveraging a safe, more productive, and easier to maintain AC solution was key for SunUp to select APsystems microinverters for this project. It strengthened SunUp’s team confidence in building reliable PV installations in challenging conditions under a tight time schedule and budget.
With the rapid development of self-consumption in both residential and larger projects, accelerated by a constant energy price increase, APsystems is very confident in the success of its current and upcoming multimodule microinverter range with the new DS3 dual series and QT2 3-phase Quad in Poland. As a proud member of Sunspec Alliance and SBF in Poland, APsystems continues to be a leader in the ever-growing solar MLPE segment offering smart and easy-to-install microinverter solutions.

APsystems Surpasses 2 GW of Shipments Worldwide
/in Article, General News, Press Releases/by APsystemsFOR IMMEDIATE RELEASE
JIAXING, China – March 7th, 2022 – APsystems, the global leader in multi-platform solar MLPE devices, today announced it has surpassed 2 gigawatts (GW) of installed capacity to date in 2022. APsystems now has more than 146,000 solar installation sites in over 100 countries utilizing its groundbreaking microinverters and rapid shutdown devices (RSDs).
The announcement comes as APsystems passes the 1-million-unit mark for RSD shipments under its APsmart brand, another major achievement for the company. Since launching in 2019, APsmart business units have experienced solid growth supported by an innovative range of SunSpec compliant rapid shutdown devices including single and dual-module solutions.
“Reaching two gigawatts is a tremendous accomplishment for our global organization and a milestone we are all very proud of,” said Dr. Zhi-min Ling, co-founder and chairman of APsystems. “Our customers around the world recognize the tremendous value and benefits of using APsystems products. This milestone is the result of our commitment to consistently add to that value and support our customers’ goals.”
In addition to the high-efficiency power conversion provided by APsystems products in sites around the world, the 2 GW milestone translates to roughly 2.8 terawatt hours (TWh) of total energy produced, with a carbon offset of more than 2 million tons of CO2.
“APsystems has been a benchmark leader in solar energy since 2010,” said Olivier Jacques, APsystems president of global business units and global executive vice-president. “We have been recognized for creating the best-selling native 3-phase quad microinverter, and, recently, the most powerful range of dual-module microinverters in the world with the DS3 series. We are driven to push the boundaries of solar power.”
APsystems’ success in reaching the 2 GW milestone as cumulative shipments of microinverters and RSD solutions, is attributed, in large part, to its global dedication to innovation combined with the experience and capabilities of its employees in each business unit around the world. Driven by customer demand, the power electronics design experts comprising APsystems’ engineering and R&D teams employ the latest breakthroughs in power inversion circuitry, semiconductor device technology, high-speed encrypted communication protocols and intelligent control.

Sizing of PV-system increases yield dramatically
/in Article, General News/by Max BoironCorrect sizing of PV system is important for increasing yield
What is the DC-AC ratio of solar panels connected to an inverter? Within the design of a PV system, the capacity of the solar panels exceeding the capacity of the inverter is called oversizing. Reasonable over ratio design can significantly optimize inverter yields, reduce AC side equipment costs and increase overall efficiency.
Why is oversizing necessary?
The nominal power of the solar panels is the maximum output under ideal conditions in a test laboratory. However, in normal life circumstances appear to be more complex, the weather is not a constant, so the output power of panels is always variable. Due to many factors, losses inevitably occur which will cause the output power of the panels to be lower than the rated power tested. If you would you like to know more about the factors that can affect the output power of modules, such as
Summary: This article demonstrates that the actual output power of the modules is lower at their nominal power. In order to improve the utilization rate of the inverter, it is considered good practice to use DC side oversizing. Using the NREL-SAM simulation example, the data proves that increasing the DC-to-AC ratio will result in higher power generation. Although there may be a loss through clipping, the increase in power generation of the system is always greater than the loss caused by clipping.The optimum ratio of direct current (DC) to alternating current (AC) ) requires a full consideration of the benefits of system power generation, system installation costs, operation and maintenance costs, and overall system production (loss of module production and mismatch effects associates etc.), in order to strike a balance between the increased costs by over-sizing on the DC side and the revenue gains generated by the electricity production of the system. Reasonable DC to AC ratio can increase system profits, reduce system cost per kilowatt hour, and maximize overall profits.
