Victron Energy BlueSolar 55W-12V Mono Solar Panel - SPM040553603

What is the maximum power of this panel and what cell technology does it use?

The Victron Energy BlueSolar 55W Mono solar panel features a nominal power rating of 55W. It is built using highly efficient monocrystalline silicon cells, ensuring excellent conversion efficiency and outstanding performance under various light conditions.

What are the physical dimensions and weight of this model?

The dimensions of this solar panel are 715 x 445 mm with an aluminum frame thickness of 25 mm. It weighs 3.3 kg, providing a robust frame construction while remaining easy to mount on various mounting systems.

What is the operating temperature range and is it resistant to extreme frost?

This photo-module is designed for demanding environments, operating reliably in a wide temperature range from -40°C to +85°C. It maintains high efficiency during freezing winter conditions as well as hot summer days.

Which charge controller is recommended for this solar panel?

To achieve maximum efficiency, it is recommended to connect the panel via a SmartSolar MPPT charge controller from Victron Energy. With a maximum power voltage (Vmp) of 21.00V and maximum power current (Imp) of 2.60A, the MPPT controller will optimize energy transfer to the battery bank.

How does partial shading affect the performance of this solar panel?

While partial shading does reduce output, the integrated bypass diodes minimize power loss. Shaded cells are temporarily bypassed to prevent hot-spots and local overheating, allowing the rest of the solar panel to continue generating power normally.

What cable and connectors come pre-installed with the panel?

The panel is equipped with a standard cable for solar system connection with weatherproof MC4 connectors. This guarantees robust commutation, IP67-rated protection, and high UV resistance.

What is the maximum system voltage supported for series connections?

The maximum system voltage rating for this model is 1000V. This allows you to connect multiple panels in series (strings) to transmit power over long distances with minimal cabling losses.

What are the open-circuit voltage and short-circuit current ratings?

The open-circuit voltage (Voc) for this panel is 24.80V, and the short-circuit current (Isc) is 2.79A. These values are crucial for selecting appropriate circuit protection and choosing correct cable sizing.

What is the manufacturer's warranty coverage for this model?

This panel comes with a 5-year limited warranty on materials and workmanship. In addition, there is a performance warranty: delivering at least 90% of nominal output after 10 years and at least 80% after 25 years of service.

Does the panel require regular cleaning or maintenance?

No complex maintenance is required. It is sufficient to occasionally (1-2 times a year, or when visibly dirty) clean the protective glass cover with clean water and a soft cloth, avoiding abrasive cleaning agents, to maintain maximum light transmission.
