This adds the voltages of all panels together but leaves the current (amps) the same.įor example, if you have four panels wired in series, each with 20 volts and five amps, the output would be 80 volts and five amps. Wiring in series refers to connecting the plus of one panel or battery to the minus of another (+-). Wiring Solar Panels and Batteries in Series The orientation you choose will largely depend on the type of charge controller you use as well as the shading where you will be placing your panels. These orientations determine whether your devices’ amperage or voltage increases - an important consideration depending on what type of controller and batteries you’re using. Solar panels and batteries can each be wired in one of two orientations: series or parallel. If you’re working on a camper van or RV setup, you may also need to take into consideration some additional components that tend to already be built into homes, or that are unique to portable/vehicular solar. Most solar system setups will require the following standard components: Choose Your Componentsĭetermining what components you’ll need and finding (or drawing) images to represent them will make your diagram come to life. Choose whichever medium suits your fancy, then move on to the next step! 2. While digital renderings tend to be higher quality and more true to reality than drawn-out diagrams, paper may give you more flexibility. This will help make your diagram as realistic as possible. If you go the digital route, consider using a flexible tool that allows you to pull in images of your components from the web, such as Canva or PhotoShop. There are several ways to create your own solar panel wiring diagram - you can draw it out on paper, print out an existing diagram and mock it up with a pen to fit your liking, or design it from scratch digitally. Below we outline how to do so, step by step. While you may be able to lean on existing wiring diagrams to build out your own system, there’s a chance you’ll want to design your own diagram. How to Design Your Own Solar Wiring Diagram It’s okay if your schematic looks a bit different from that of another solar DIYer, as long as everything is connected properly. There’s no such thing as a single correct diagram - several wiring configurations can produce the same result. What Is a Solar Panel Wiring Diagram?Ī solar panel wiring diagram (also known as a solar panel schematic) is a technical sketch detailing what equipment you need for a solar system as well as how everything should connect together. You’ll be ready to power up your home or get on the road in no time. In our guide, we unpack how to wire solar panels and provide diagrams illustrating solar schematic examples for every solar setup, from residential to RV to camper van. Schematics is one of the more technical parts of DIY solar, but it doesn’t have to feel like rocket science. This will essentially serve as your map as you connect all of your components. One very important step when constructing your own solar setup is putting together a solar panel wiring diagram (or schematic). To do it right, you have to devote a lot of time and forethought into how it will come together. Like any other electrical DIY project, setting up a solar system yourself can be a complicated process.
