Monocrystalline solar panels stand out in the photovoltaic sector for their high energy conversion efficiencywhich reaches values between 16% and 24%. This type of panel consists of solar cells made with a single crystal of silicon, which ensures a higher efficiency than polycrystalline panels, which are between 14% and 18%. Despite superior efficiency, monocrystalline cells have structural fragility that can impact operation and energy efficiency over time, requiring appropriate encapsulation methods to ensure stability and durability.
To improve the strength and versatility of monocrystalline panels, Merlin Solar Technologies introduced innovative technology based on metal grills integrated into the cells. This approach increases the number of connections within the cells themselves, making the panels more robust and flexible, a feature that significantly expands installation possibilities, including on curved or irregular surfaces.
Metal grids and greater resistance for monocrystalline solar panels
One of the key innovations to increase the strength and flexibility of monocrystalline solar panels is the metal grillswhich create numerous interconnection points within and between cells. This configuration not only reduces the risk of microcracks and structural damage, but also allows the panels to better withstand mechanical stress. A further advantage of the metal grid is the optimized management of partial shadows: in case of partial shading, the energy is effectively redirected, ensuring stable conversion and minimizing power losses.
Typically, without this metal grid technology, monocrystalline panels must be encapsulated between two layers of glass and secured in a frame to prevent cracking. However, this process makes the panels heavier and more difficult to install, whereas with metal grilles the panel remains lightweight, allowing for simpler and more flexible installations.
The addition of the metal grills allowed for development highly flexible monocrystalline solar panelswhich can also be applied on irregular surfaces. Without the need for support frames, these panels adapt perfectly to curved roofs, vehicles and movable surfaces such as those of campers and trucks. The panels can power on-board devices such as refrigerators and lights, helping to reduce fuel consumption on the road.
Furthermore, this type of panel is particularly suitable for light or curved residential or commercial roof applications, offering easier installation thanks to their lightness and flexibility.
