Adding a 300 Watt 24 Volt black frame Monocrystalline Solar Panel to a home or commercial building is the first step in converting the structure from being energy-dependent to energy producing. Primarily used for residential and commercial purposes, rooftop solar power systems are the perfect way to decrease an electric bill. Also great for large off-grid systems, the 300W Monocrystalline Panel can be used in multi-panel solar arrays for cabins and sheds. The included PERC solar cells are efficient and help make the panel smaller and lighter. Compared to a regular 72 cell 300 watt panel this panel is 15-20% shorter and lighter. Complete a large scale project with 300W solar panels, perfect for on-grid or off-grid projects.
