2 Typical Battery Powered Outdoor System with PV Panel

PV system is used to convert the light into electricity by using semiconducting materials that exhibit the photovoltaic effect. A PV system is composed of one or more solar panels combined with an electrical and mechanical hardware that use energy from the Sun to generate electricity. In some battery powered outdoor equipments, sometimes there are PV panels which is used to charge the battery and increase the usage time of battery, such as video doorbell, wireless camera, and so on.

Figure 2-1 is the function block diagram of a battery powered outdoor equipment with PV panel.

The system requirements are listed in Table 3-2.

Table 2-1 System Requirements of Battery Powered Outdoor Equipment with PV Panel
Parameters Values
Solar Panel MPP voltage approximately 2.9V
Charge Current 1A
Charge Voltage 4.2V

The MPP voltage is important and decides the output power of the PV panel and if the PV panel can operate with the highest efficiency.
