The conversion efficiency of solar panels refers to its efficiency in converting solar energy into usable electricity. The efficiency of solar panels has improved significantly in recent years, and the conversion efficiency of solar panels currently on the market is typically between 15% and 22%. High-efficiency solar panels can reach nearly 23%. Our Perc solar panels can reach 21%, and Topcon can reach 22%.

Photovoltaic power generation is a technology that converts light energy directly into electrical energy by using the photovoltaic effect of semiconductor interface. It is mainly composed of solar panels, controllers, inverters, batteries and other accessories (grid-connected systems do not require batteries).

Photovoltaic power generation systems are generally divided into grid-connected solar systems, off-grid solar systems and hybrid solar systems.

Grid-connected solar systems are connected to the grid, and the electricity generated by the solar panels is sent directly to the grid. Off-grid solar systems are not connected to the grid, and the electricity generated by the solar panels is stored in batteries. The hybrid solar system is connected to the grid and has a backup battery system to store excess power. Both hybrid and off-grid solar systems are supported by batteries, but hybrid systems are more efficient than off-grid systems. In off-grid systems, no power is available once the battery is depleted, while hybrid systems can use power from the grid when needed.
