The technological evolution of photovoltaic panels has consistently altered the performance of solar systems in recent years. New cell designs, changes in module architecture, and… more efficient materials They have been expanding power generation and reducing operational losses.
Within this context, DAH Solar announced the launch of a new 650 W photovoltaic module, which will be available in different versions and focused on large-scale and rooftop applications.
The solution was developed to meet the needs of ground-mounted solar power plant projects and commercial and residential systems, combining higher power output, increased efficiency, and reduced maintenance requirements over time. The arrival of the photovoltaic panels on the Brazilian market is expected in early 2026.

The new 650 W module will be available in two versions: Full-Screen and Conventional. Both share advancements in photovoltaic cell design, but differ in surface treatment and performance in environments with higher dirt accumulation.
According to the manufacturer, the reduced spacing between cells increases the active area for energy conversion. As a result, there is better use of sunlight and an increase in the module’s energy density.
Furthermore, this configuration contributes to additional generation gains and reduces the need for corrective interventions during operation.
In projects where space is limited, this factor becomes strategic, as it allows for extracting more energy per square meter installed.
In the Full-Screen version, the main difference lies in the design that minimizes the accumulation of dust and debris on the surface of the photovoltaic panels. According to analyses by the company itself, this feature can result in a gain of up to 15% in energy production, especially in regions with a high concentration of dust or atmospheric dirt.
This performance is relevant for projects installed in rural areas, semi-arid regions, or locations with infrequent cleaning.
Reducing particle buildup also helps lower operating costs, since maintenance needs tend to be lower over the system’s lifespan.
The 650 W module boasts a conversion efficiency of 24,06%, a figure considered high for commercial photovoltaic panels. This performance is made possible by the adoption of the latest generation TOPCon technology, which reduces internal losses and increases energy capture.
Furthermore, the combination of larger wafers, optimized cell architecture, and adjusted dimensions increases the flexibility of use. According to the company, the module was designed to adapt to both large ground-mounted plants and rooftop systems, maintaining high performance even in less favorable conditions.
This feature meets the growing demand for solutions that combine high power and installation versatility.
Another point highlighted by DAH Solar is the warranty policy associated with the new photovoltaic panels. The modules come with a 15-year warranty on materials and manufacturing, in addition to a 30-year warranty on energy generation.
According to the company, this commitment reflects the product’s reliability and the expectation of consistent performance over decades.
“The 650 W modules represent the most advanced technology in Full-Screen and TOPCon solutions, delivering higher energy production, lower maintenance, and excellent cost-effectiveness. We want the Brazilian market to have access to products that increase the competitiveness of photovoltaic systems and offer the best performance over time,” highlighted Thais Bittencourt, the company’s marketing manager.
The first units of the 650 W module are expected to arrive in Brazil in early 2026. Furthermore, the manufacturer already anticipates launching an even more powerful 670 W version later this year.
With this, the company expands its portfolio of high-efficiency photovoltaic panels, following the global trend of increasingly powerful, durable modules adapted to the different realities of the solar market.
