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

A: Off-grid systems work independently and usually use batteries for storage. On-grid systems connect to the utility grid and can use grid power when needed.

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

A: Common causes include cloudy weather, shading, dirt buildup, poor installation angle, or high temperatures.

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

A: It depends on your system requirements.

• Series connection increases voltage
• Parallel connection keeps voltage the same and increases current
