What does off-grid and on-grid mean ?

On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use.

Why is my solar panel under producing ?

Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output.

How should I connect solar panels in my electrical circuit (series vs parallel)

Connecting solar panels in series will have the effect of adding up their operating voltage output, while system current output will be the same as that for one panel. While, connecting solar panels in parallel will have a different effect;

How many solar panels do I need ?

To determine solar panel needs, calculate the power load (Watts) and capacity (Watt-hours). Size the battery bank based on minimum capacity, then adjust panel quantity or power input accordingly.

What is the meaning of 12V in the product title，Why is this value different from the voltage of the solar panel？

When you open the product page, you will see a title like "xxx Watt 12 Volt Solar Panel". The "12V" here does not refer to the voltage of this solar panel (VOC or VMP), but to the fact that one xxxW solar panel is suitable for 12V system.
