What Happens If One Solar Panel Fails?
Solar panel failures can impact your system's performance. The extent depends on your setup and how quickly you spot the issue.
How Solar Panel Systems Work
Your solar panels capture sunlight and turn it into electricity. This power flows through wires to an inverter, which changes it into usable energy for your home.
Each panel in your system connects to others. They form a network that sends power to your house and sometimes back to the grid.
Your setup can use series or parallel wiring. This choice affects how your system handles panel issues.

Series vs. Parallel Configurations: Which Is Better?
In a series setup, your panels link like a chain. If one panel fails, it can affect the whole system's output. Think of Christmas lights - when one bulb goes out, the whole string might stop working.
Parallel setups are different. Here, each panel works more independently. If one fails, the others keep producing power. Your system loses less energy overall.
Series setups are simpler and often cheaper to install. They work well when all panels get equal sunlight.
Parallel configurations shine when some panels might get shaded. They're more complex but offer better performance if a panel fails.
Your installer can help you choose the best option for your roof and needs.
