There are 3 ways to connect solar panels; parallel, series, and a combination of parallel and series. There are three main types of connection patterns that allow for batteries to be connected to a solar panel. its hard to charge directly from the panels. The battery charge cable attaches the same way. Wiring is simple - it's all "plug and play". Generally speaking, if you need to increase the voltage output of the system, the best option is to connect the solar panels in series. When looking at this symbol the triangle points in the direction of flow, when looking at the diode in your hand there should be a colored line around one end of it. Parallel wiring in your case will probably be the worst option because, whilst the current will be additive, the overall system voltage will be limited to the lowest voltage panel i.e. Additionally, the panels should be inspected periodically for damage, such as cracked glass or loose connections, and repaired as necessary.
