This video shows my solar energy setup here in Manila, Philippines. There are three 40 watt panels, a 10 watt panel and a 5 watt panel. Suitable for charging devices, lighting and much more.
The 5 watt panel either runs a USB fan or charges a 1.7Ah Lithium-ion battery.
The 10 watt panel charges a 7Ah deep cycle battery which runs a raspberry pi connected to ethernet.
The 3×40 watt panels (120 watt total) charge a 100 Ah solarmaster (motolite brand) battery which I use for charging gadgets like phones, tablets and the kind of thing. I also have a 500 watt inverter connected so I could potentially run pretty much any household item in an emergency situation.
