Connecting Small Solar Panels

Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while keeping the same voltage.

Connecting small solar panels.

These wires also need fuses which protect the wires by blowing if the electrical current gets too high. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. Parallel connection of two identical solar panels. For this example i am showing you connecting panels that are for a 12 volt system.

Most mini solar panels either use a monocrystalline silicon solar panel polycrsystalline silicon solar panel or a thin film solar panel to generate solar power from sunlight. Connecting solar panels in series the series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires.

With portable solar panels an amazing charging speed can be achieved charging smartphones up to 20 in just 10 minutes that s 75 faster than connecting your phone to a power outlet. A thin film solar panel are made by solar cells that have light absorbing layers and much smaller than a standard silicon panel which allows it to be light. At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity. Wiring solar pv panels in parallel the next basic type of connecting solar panels is in parallel.

Parallel series and a combination of parallel and series. If we have two solar panels with same voltage and power the connection will be very simple. And all you need is a usb cable.
