This article introduces the main categories of solar panels, including monocrystalline silicon, polycrystalline silicon, amorphous silicon, and multi compound solar panels. Monocrystalline silicon solar panels have the highest conversion efficiency (up to 15% -24%) and the longest lifespan (15-25 years), but the cost is relatively high; The efficiency (about 12%) and lifespan of polycrystalline silicon are slightly lower, but the cost-effectiveness is still acceptable; Amorphous silicon can generate electricity under weak light, but its efficiency is low and unstable; Many compounds are not yet industrially produced.

This article introduces the selection method of solar system controllers and the design process of off grid solar systems. The selection of the controller should be based on the usage scenario. For portable small systems, the economical PWM type can be chosen. For base stations and other scenarios, the MPPT type is recommended, and the amperage is not necessarily better. Designing an off grid system requires first calculating the load capacity, then determining the power of the battery and solar panels, and finally configuring the controller based on relevant parameters.
