Using solar energy as an alternative source of energy with all its advantages can be a bit troublesome. This is so because you cannot control the whims of the weather, even with a weather forecast it can still be unpredictable. You can, however, make good use of the source when it is available by saving it into batteries to create a solar battery bank. This way, you are assured of having good energy stored up when you need it. You will also be able to increase the lifespan of battery cells instead of throwing then away after one or two recharges.

TOOLS:

Soldering iron and solder

Wire cutters

Hot-glue gun and hot-glue sticks

Scissors or knife

MATERIALS:

3-6x Flat Top Li-ion Batteries Bulk 2500mAh (*can be recovered from taking apart a laptop battery)

3x 1.5v Solar Cells (**can be salvaged from solar lawn lights)

1x TP4056 5v charging circuit ($0.27)

1x DC Boost Module step up Converter 3V 3.7V to 5V circuit ($0.80)

Some wire

Heat-shrink insulation

A project box or other case

Epoxy

A battery bank is made up of rows of batteries connected in such a way that batteries in a row form a series, while the rows are connected to form a parallel. Putting this together, however, will require some careful calculation to avoid having a short circuit. You should ensure that the batteries are all loaded to the same voltage if not, the whole battery could light up in flames. You can measure the voltage of each battery using a solar battery bank monitor.
