BlueSolar 20W-12V Mono Solar Panel Victron Energy - SPM040203603

What is the peak power of this module, and what technology is it made of?

The Victron Energy BlueSolar 20W Mono photovoltaic panel has a nominal power of 20W. It is manufactured using highly efficient monocrystalline silicon cells, which guarantees increased efficiency and excellent energy production in all weather conditions.

What are the physical parameters (dimensions and weight) of this model?

The panel's overall dimensions are 275 x 450 mm, with a 25 mm thick aluminum frame. The device weighs only 1.3 kg, ensuring both high structural strength and maximum ease of installation on any surface.

What is the panel's operating temperature range, and is it resistant to extreme cold?

This solar module is designed for use in harsh climates and operates reliably in temperatures ranging from -40°C to +85°C. It maintains high generation efficiency both in extreme winter temperatures and during the summer heat.

What type of charge controller is best for this model?

For maximum system performance, it is recommended to connect the panel through a SmartSolar MPPT intelligent charge controller from Victron Energy. With an operating voltage (Vmp) of 21.00 V and a current (Imp) of 0.95 A, this device ideally optimizes energy transfer to the batteries.

How does partial shading affect the efficiency of a PV module?

When a part of the panel is shaded, overall output decreases, but thanks to integrated bypass diodes, power losses are minimized. Shaded elements are temporarily isolated from the overall circuit, preventing them from overheating and allowing the rest of the panel to operate normally.

What is the maximum circuit voltage allowed when connected in series?

The maximum system voltage for this model is 1000 V. This allows several panels to be connected in series into long strings to transmit generated electricity over long distances with minimal power loss.

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

For this panel, the open-circuit voltage (Voc) is 24.70 V, and the short-circuit current (Isc) is 1.99 A. These parameters are critical for the correct selection of protective automation and cable cross-section calculations. lines.

What warranty does the manufacturer provide for this product?

The manufacturer provides an official 5-year warranty on workmanship and materials. A long-term performance guarantee is also in place: the panel will retain at least 90% of its rated output after 10 years of operation and at least 80% after 25 years.

Does regular cleaning require any basic maintenance for the panel surface?

The module does not require any specialized or complex maintenance. To maintain maximum light transmittance, simply wash the protective tempered glass periodically (1-2 times a year or as needed) with clean water, without the use of chemicals or harsh abrasives.
