How to connect solar panel in series.

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. Connection solar panels in series diagram first of all connect solar panel positive connection with other solar panel negative. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. Nonetheless it is possible to wire them in parallel.

In last you will find out that you have negative wire free form you first solar panel and positive from you last panel. Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array which are to be connected to the input either of the inverter in case of a grid tied system without a battery backup or the charge controller in case of a grid tied system with a battery backup or off grid solar panel system. This way two 6v or 12 or 24v 150w 12 5a solar panels and 12v 100ah batteries connected in series would have the following values. Continue this process with all panels.

Series connected solar panels batteries we may connect two solar panels or batteries by connecting their negative terminal to the positive terminal and vice versa. Since each panel is 12v and the battery bank you want to charge is 24v then you need to series your system to increase the voltage. For photo voltaic components attached in parallel absolute power is determined as cited below. When you connect the positive terminal of one panel to the negative terminal of another panel you create a series connection.

When stringing panels in series each panel additional adds to the total voltage v of the string but the current i in the string remains the same. For safety use the open circuit voltage to calculate series connections in this case the 100 watt panel has 22 5 volts open circuit and 5 29 amps. Solar devices are normally attached in parallel to achieve greater output current. Series connection of two solar panels with different current if we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series.

When stringing in series the wire from the positive terminal of one solar panel is connected to the negative terminal of the next panel and so on. Add up to combined power 150w 150w 150w 150w 600w.
