FAQ

Q: What is the difference between off-grid and on-grid solar systems?

A: Off-grid solar systems operate independently and typically use batteries to store energy for later use. On-grid solar systems are connected to the local utility grid, allowing you to use solar power while also drawing electricity from the grid when needed. In many areas, on-grid systems may also qualify for net metering benefits.

Q: Why is my solar panel producing less power than expected?

A: Reduced output can be caused by several common factors, including cloudy weather, partial shading, dust or dirt buildup, improper installation angle, or high operating temperatures. Regular cleaning, proper positioning, and checking your system connections can help improve performance.

Q: Should I connect solar panels in series or in parallel?

A: It depends on your system requirements.

Series connection increases the total voltage and is often used when your inverter or charge controller requires a higher input voltage.
Parallel connection keeps the voltage the same while increasing the current, and it can help reduce the impact of shading on overall system performance.

Always make sure your panel configuration matches the voltage and current specifications of your inverter or charge controller.
