[PDF Version]We are talking about parallel connected solar panels and series connected batteries. This wiring can be done for multiple voltages systems when the solar panel voltage rating is half as compared to the batteries (e.g. 6V PV panels and 12V batteries or 12V solar panels and 24V batteries.)
Depending on the system requirements and design, solar panels and batteries can be connected in series, parallel, or a more complex series-parallel configuration to meet specific needs. In this tutorial, we will explain the basic wiring of photovoltaic panels in a series-parallel configuration.
Only the same rated solar panel can be connected in series, parallel or series parallel connection. A 12V solar panel can only be connected in (series, parallel or series-parallel) with another 12V solar panel. A 12V solar panel should not be connected (in series, parallel or series parallel) to a 6V or 24V solar panel.
In parallel connection, similar terminals of two solar panels or batteries are connected by jumper wires. For example, two 6V (or 12 or 24V) 150W, 12.5A solar panels and 12V, 100Ah batteries connected in parallel would have the following quantities: 100Ah + 100Ah = 200Ah. The voltage for solar panels and batteries remains the same in parallel connection.
For a 24V DC solar panel system, both the batteries and solar panels may be wired in parallel connection. The same 24VDC system can be achieved by wiring solar panels in parallel and batteries in series in case of the double voltage rated solar panels as compared to the batteries voltage (e.g 24V Panels in Parallel and 12V batteries in Series).
