By [Elliot Clark](https://energytheory.com/author/elliot%5Fclark/)November 17, 20232 Mins Read ![JAN23 What is Parallel Connection in Solar Panels](https://energytheory.com/wp-content/uploads/2023/06/JAN23-What-is-Parallel-Connection-in-Solar-Panels-1024x683.jpg "What is Parallel Connection in Solar Panels?") When solar panels are connected in parallel, the overall voltage output of the system remains equal to that of a single panel. However, the total output current increases as the sum of the current generated by each individual panel. A notable effect of implementing parallel wiring for panels is the augmentation of the output current, as it manifests as the cumulative sum of the individual amperage of each panel. In simple terms, a **parallel connection keeps the voltage consistent** while the amperage adds up. The current result of a solar panel depends on factors such as its area (surface) and the amount of sunlight it receives, known as irradiance. The current and power output increase when we connect PV panels in parallel connection. Photovoltaic cells typically produce power at around 0.5 to 0.6 volts DC; the current they generate is proportional to the cell’s area and the sunlight falling on it. However, the opposition of the connected load determines the actual number of amperages given by a panel or cell. ### **Concept of Connecting Solar Panels in Parallel** While you connect [solar panels](https://energytheory.com/specifications-of-solar-panel/) in parallel connection, the current will be measured in amperage, and add up while the voltage remains unchanged. Here’s an example to illustrate this concept. Imagine you have four solar panels, each rated at 12 volts and 5 amps. When you connect these panels in [parallel](https://www.allaboutcircuits.com/textbook/direct-current/chpt-5/simple-parallel-circuits/) connection, the entire array maintains a **voltage of 12 volts,** just like a single panel. However, the current adds up for every branch. In this case, the total **current** of the array would be **20 amps,** which is the sum of the individual panel amperages. So, parallel connection in solar panels allows you to **combine the current output of multiple panels while keeping the voltage consistent.** This parallel configuration increases the overall power capacity of your solar setup, enabling you to harness more energy from the sun. **Also See:** [What is a Panel Mismatch?](https://energytheory.com/what-is-panel-mismatch/) Share.
