How It Works
When exposed to sunlight, the photovoltaic cells generate DC electrical power. The panel can then be connected to a suitable load or, with an appropriate solar charging/management circuit, used to charge a compatible rechargeable battery.
Important: Do not connect the solar panel directly to a Li-ion/Li-Po battery unless the charging circuit is specifically designed to regulate and manage solar charging.
