300 watt mono solar panel specification
300 watt mono solar panel is the ideal size for small and medium sized off-grid PV system, its size is 1350*1134*35mm. one person can easily move and install it. So, it is also widely used for off-grid cabin, boat, camper, dining car. If you just use it for lighting, you can install a PV panel, which can generate about 1400Wh of electricity per day. If you also have home appliances such as computers, washing machines, fans, etc., then multiple PV panels will be needed in series.
Paired with a PV charge controller, the 300watt mono PV panel can charge lead acid batteries, gel batteries, AGM batteries, and lithium batteries. Provides power for living at night.

300w solar panel Features
HALF-CUT TECHNOLOGY: The 300 watt PV panel utilizes advanced Half-cut technology. The PV panels can increase power generation by at least 30% when shaded.
Monocrystalline Cells: This is the most advanced PV cell technology available, with a power degradation rate of less than 1% per year.
Quick installation: the MC4 connector can be directly adapted and connected to other devices, such as mobile power. PV inverter etc.
Aluminium alloy frame: it can protect the PV panels from being damaged by impact. And there will be no rust.
High transmittance toughened glass: it can increase the degree of PV panels to receive the sunlight and can protect the panels.
