High-Efficiency 200W Monocrystalline Solar Panel for RV, Marine & Off-Grid

Upgraded Design

The 200 W monocrystalline silicon solar panel adopts the latest half-cut cell technology, dividing the panel into two parts. Compared to ordinary solar panels, it can reduce power loss by 4 times, increase output power by 1.5%, and achieve a conversion efficiency of up to 24%.

Reduced Power Loss

The solar panel uses half-cut cell technology to reduce internal current and line resistance, thereby decreasing internal power loss. This results in a lower working temperature for the module and junction box, with the temperature of the half-cut cell module being about 1.6°C lower than that of conventional cells. Lower temperature translates to higher photovoltaic conversion efficiency.

Efficient Performance

The bypass diode design allows the solar panel to create an alternative path for current flow in non-shadowed areas, avoiding the effects of shaded areas. This improves performance and makes the 200 W solar panel ideal for charging 12-volt batteries. Multiple panels can be connected in series for use with 24/48-volt battery systems.

Built to Last

Each 12-volt solar panel is equipped with specially designed pre-drilled holes for easy installation. The panels feature a corrosion-resistant aluminum frame and can withstand strong winds of 2400 Pa and snow loads of 5400 Pa. Two wiring boxes ensure that the upper and lower panels work independently. Even if one panel experiences partial damage, the other panel can still function.

Tips for Using

The power of solar panels fluctuates based on environmental conditions, with optimal performance when light is perpendicular to the panels. The optimal working temperature is 25°C. For every 1°C increase in temperature, power is lost by approximately 0.35% to 0.45%, and voltage is reduced by about 210-212 mV. External components like controllers and inverters also contribute to power loss.
